Planetary Imaging

[white prawn]

That may also be "47fps at 4k resolution". If I use lower screen size I get 192fps. I don't think I'd get that if I set it to 4k capture

[cloud copper]

oh

guys isnt this the mars-c camera?

[white prawn]

I don't have an answer on that one.

[cloud copper]

because I see that it says TS-Optics but I looks like Mars-c

it has the same imx sensor too

[livid sierra]

@cloud copper TS-optics camera use the same hexagon design as Player One

I don’t know anyone who uses them though

And yes like @white prawn said the 42fps limit is at full resolution

But you’re most likely never going to actually record planets at the full resolution but with a region of interest (ROI) instead which’ll give you faster fps too

Also the Mars-c is based on the imx462 not the imx464

[white prawn]

Which is why I record at 640x480 mode

[ruby tartan]

SV105 is a toy, don't buy it, it's worse than using a cell phone

[white prawn]

Ouch. Harsh, possibly more than what is deserved. Understandable why you're saying it, still think it's harsh. 🤷‍♂️

[ruby tartan]

Trust me, I already tested one that a friend had. The reason it is bad is that instead of cropping the sensor, it decreases the resolution, just like a cell phone

[white prawn]

So when I tell my ASI585 to record at smaller screen (640x480 instead of 1280x1024 for example) it's cropping the sensor instead of decreasing quality, where the 105 would be decreasing quality, am I thinking correctly?

Or do I need to learn how to use the ROI section in SharpCap?

[ruby tartan]

That way, it just cuts off the sensor's viewing area, it's as if it deactivates the area it won't use. As for the sv105, it works just like a cell phone camera, if you've already downloaded those custom camera apps on your cell phone, you must have seen that when selecting to record with a lower ROI, it will reduce the final quality,

[somber stratus]

Same as Player One Neptune C-II (IMX464)

good cam for sure

between Uranus-C (585) & Mars-C (462)

[cloud copper]

yea

I think ith Neptune-C as you said beacuse the sensor is the same and the images are the exact same as the ones for Player One astronomy

you can check it out here https://astromagazin.ro/camere-pentru-astrofotografie/14276-camera-ts-optics-ts464c-usb30-color-cmos-d-9-mm.html

This isnt right :/

[somber stratus]

i'd use the actual TS optics website

tbh

[cloud copper]

yea for sure

Tom, what do you think about Ceres-c? It has an Imx 224 with 154 fps at max resolution. Looks good for the price, doesn't it?

[ruby tartan]

I texted Sean and asked if he knew about it

[cloud copper]

and?

did he say anything?

[ruby tartan]

I'm waiting for the answer

[cloud copper]

ok

[somber stratus]

Might be a scam website, rather than TS optics themselves

ik Lyaphine works for/with TS - very respectable company

more the suspect website for me

[somber stratus]

Decent enough.

[cloud copper]

the website isn't a scam one, I bought my telescope from there but its confusing

[somber stratus]

Certainly better cams, but not at that price point

[cloud copper]

Yea, I think this is the best one at that price range out there

I wish more second hand astrophotography stuff were in Romania

I'm stuck to buying new cameras and they are very expensive XD

do you think ceres-c needs a uv/ir cut filter @somber stratus

[somber stratus]

All cameras do for optimal performance

OSC cameras*

[cloud copper]

any other filters that could help me get better results with it?

[somber stratus]

not particularly

[livid sierra]

Uvir cut is just to get true rgb images

Without the uvir cut you’d obviously get uv and ir interference and you’d miss out on certain detail and things that’s only visible with ir blocked for example

Like clouds on Mars

[somber stratus]

Clouds on Mars are visible in all wavelengths.

[livid sierra]

They are?

[somber stratus]

yes, just blue has them most contrast-y against the albedo markings of the terrain

Less visible in IR, but still there

[livid sierra]

Oh right

[somber stratus]

It's more the IR leak stopping you ever reaching focus on most setups. UV/IR cut allows true colour, and maximal sharpness

[livid sierra]

Yes that was it

[somber stratus]

Bc it usually focuses differently to visual bands

[cloud copper]

Ok thank you all!

[upper jewel]

The ZWO 224mc is a good planetary right?

Anyone also use the 224 for guiding though as I'll probably use it a lot more for guiding

When is it planet season anyways?

Got my only pic of Venus and the pleades by accident but really put a smile on my face after a disappointing night 🌙

2nd pic is just zoomed into the corner

[cloud copper]

224mc is good for planetary

planetary season starts in the sumer I think

[upper jewel]

👍

[somber stratus]

smooth

[flint veldt]

very smooth

[onyx garnet]

insane, great stuff

[ruby tartan]

Hi Lucaa, it's a OK, they told us that is a marketing strategy.

[somber stratus]

hmm

[cloud copper]

strange

[cloud copper]

Really nice! But is Jupiter still visible to you? Here it isn't all day long.

[sharp ridge]

Jupiter just passed solar conjunction, so right next to the sun

should start to be visible in Uune/July?

[cloud copper]

yea, it starts in july I think

[livid sierra]

These videos they’re sending are from last season

Sick shot of mars, love that face

[somber stratus]

Against the 4 bois

[somber stratus]

yeah it's actually my second shot ever of Syrtis Major

Just been clouded when it's been visible

[hasty hull]

Shame

[hasty hull]

Are Phobos and Deimos able to be extracted from this or is it harder now

[somber stratus]

urm

i can look, but X to doubt

nope, nothing

[white prawn]

What kind of scope does one need to be able to resolve the Galilean moons like you have there?

[somber stratus]

= 14” aperture

[white prawn]

So 8" and ASI585 w/ 5x and 3x stacked Barlow lenses won't do it. Gotcha. 😁

[scarlet field]

>Hubble

[near quiver]

Before planetary season this year I plan to buy a Uranus C and a nice 3x Barlow

Unfortunately a 16” dob is unrealistic for me right now but I might be able to upgrade to a 10 or 12 inch too

[coarse aspen]

You can get great results with your 8", id stay with it maybe for a little bit

[somber stratus]

Unfortunately not lol

When you’re dealing with sub-arcsecond detail on Moons, you need intrinsic resolving power which is linearly proportional to aperture.

As you have half the aperture, If Ganymede was twice the size at 3.6 arcsec, you’d have a good chance.

That said, Uranus is about this size. Possible to get polar hood detail with an IR filter.

[near quiver]

sure, but if i see the chance to get a cheap upgrade ill go for it

[cloud copper]

guys what the best phone app for planetary astrophoto

like best camera app

to control the iso and shutter speed and stuff XD

[white prawn]

Sorry, all the photos I took with my phone were taken w/ the native phone app, nothing special downloaded.

[near quiver]

astroshader is really good for iphone, not sure what android people use

[near quiver]

oh sorry i didnt even notice this was the planetary chat

use fotogear on iphone, still dont know for android

[upper jewel]

Start to be yes, it is most visible this year on Dec 28th

It is just approaching solar conjunction I believe and is also very low on the horizon atm

[summer field]

November 3rd for 2023 jupiter opposition 🙂

[nova delta]

Mercury and Venus opposition date? 🧐

[livid sierra]

Damn almost my birthday

Opposition is 6 days too early

[hasty hull]

Venus in UV just now

[main flume]

Venus with 8” dob nd iphone

[somber stratus]

Fat prom today. Quick in-the-field process

[somber stratus]

Going for a odd IR narrow band Venus combination

RGB mapped to IR (1010/38), CH4 (889/20), R (650/50)

Should get different layers of atmosphere

Maybe

[cursive inlet]

Interesting

[livid sierra]

That’s gonna be funky as hell I bet lol

[ruby tartan]

Does anyone notice any difference?

[near quiver]

yes definitely

right looks way better

[steep apex]

Yeah that circle thingy is gone on the right

[livid sierra]

The ringing is gone

[somber stratus]

Looks pretty good chief. What did you use?

[sharp ridge]

Huge difference mate

[cloud copper]

guys is a GSO ED 3x barlow lens a good one, it is an apochromatic one with 2 lenses

it is 42 euros

[ruby tartan]

I used this tool in photoshop. I will record a video using

[somber stratus]

Dodge tool?

interesting

[somber stratus]

please do

[cloud copper]

Guys, what is better for planetary imaging, a 150/1400 newt or an 84/1200 refractor

[livid sierra]

Newt

[ruby tartan]

Newt

[cloud copper]

what is the refractor good for then ?

[ruby tartan]

DSO images

Wait, is this refractor F/14?

@somber stratus

[somber stratus]

quite tedious, but works

[livid sierra]

Very interesting

[ruby tartan]

Mars IR685

[knotty salmon]

@somber stratus What does your FOV on mecury look like? And how do you go about lining up on the planet and focusing?

[somber stratus]

And i just aligned on venus, slewed over. Spotted in eyepiece, switched in the camera and focused as normal.

[knotty salmon]

Awesome, what about tracking?

[somber stratus]

Just used tracking motors. Keeps planet in FOV for around 5-10 mins

[hasty hull]

Saturn 10 mins after sunrise

[somber stratus]

Seeliger

[white prawn]

That looks really nice.

I have yet to bring out that sort of color in my Saturn photos. They've all been w/ a DSLR through a Barlow. Except one was through an SV105. Would you mind handing me a tip? 🙂

[somber stratus]

What, the blueish hue of the southern hemisphere, or just general color balance?

I record in raw (no color balance) with the Uranus-C. Appears very green-heavy, then just levels-->auto adjustment in Photoshop.

• saturate

[white prawn]

Just the general color balance.

In general when processing when is the time to do the RGB balance? After doing a sharpen/denoise or before? I processed an image of Jupiter the other night that came out kind of "ew" and I did the RGB balance before doing the sharpening. I feel like if I had done it after it would have looked better.

[somber stratus]

I tend to do it after sharpening, and derotation.

One of the final steps

[white prawn]

Ah. Sharpen, derotate, RGB balance, then play with sat and such.

[somber stratus]

This is what I have before PS

[white prawn]

But, how long are you recording that you wind up having to derotate?

[somber stratus]

Saturn, 30 mins. Jupiter 15. Each multiple 90-120sec captures. So like ~15-20 vids for Saturn, and 8 for Jupiter

[white prawn]

Aha. Okay. What I've been doing is recording up to 3min videos, stacking just that one video. I don't put it all together to have to derotate. I did try my hand at a Jupiter rotation video once.

I tried recording Saturn for a 20 min video once. I didn't see the difference between using the good frames from one 20 min vid vs. a 3-5 min vid.

I also haven't been doing this for quite a year yet and I'm still learning. Programs, equip. I think I'm doing okay for what I have though.

My images after stacking are either orange or gray, and without the detailed banding. Let me guess, 14" to resolve that level detail?

[ruby tartan]

Isn't 120sec for Jupiter too much in one video, even more so for a 16"?

[somber stratus]

I usually do 105-sec, and AS!3 copes with it absolutely fine

even with Io in transit.

Got a s23 ultra to try... now to figure out how to turn off the cyborg cameraman inside 🤔 😆

[steep apex]

This is pretty good for a phone!

[cloud copper]

could you send me the avi file

I want to try to process it

[cloud copper]

but how do you get still clouds, without them moving

[somber stratus]

Not sure what you mean

[white prawn]

I think he's referring to Jupiter rotation being visible over a short time span and substantial enough in a 15 minute window. So how do you get 15 mins of data showing movement, to not move. 🙂

[somber stratus]

Ah, derotation in WinJupos then

[ruby tartan]

I published my Saturn files for this year there in #1100095820575027230 if anyone wants to give it a try

[somber stratus]

reupload in a zip file instead

most people don't have winrar

[ruby tartan]

Ok

[somber stratus]

2 minute video. Best 10%, vs worst 10% of frames.

Yes the same capture video

[jaunty flame]

small difference

[somber stratus]

20° altitude for you

[summer field]

reprocessed some 2021 jupiter data

[coarse aspen]

insane difference

the second one looks out of focus in comparison

[blazing hazel]

thats crazy

how good would i be able to get with a 10'' dob with an iphone?

[coarse aspen]

2021 jupiter has better colors

[blazing hazel]

i also have a nikon d3000 . what would be better to use?

untracked dob also

[somber stratus]

definitely the biggest change in a year i've seen, barring 2010

[summer field]

yeah, 2021 jupiter looks very different from the other years

[hasty hull]

Never seen it look the way it did in 2021

Very unique

[wary siren]

yea I started planetary astrophotography in 2021, jupiter looked really cool

[white prawn]

You guys all saying I missed out on some really cool stuff by coming late to the game?

[onyx garnet]

does this framing look good?

[livid sierra]

I mean

[somber stratus]

what f/ratio is that, f/20?

6SE is f/10 native right

[livid sierra]

It’s not like rotating it 45° or recording Jupiter off centre is gonna change much

[onyx garnet]

yes

[somber stratus]

yeah, works

[onyx garnet]

alr cool

[hasty hull]

Mars tonight. 5.5” across

[cloud copper]

Guys, is there any way to make some money for astrophotography?

[white prawn]

Get REALLY good at it, like James Peach level of good or better, and be able to sell prints.

Otherwise, enjoy the hobby.

[livid sierra]

Do you mean for or through

If you mean for; prolly just get a job

Or start a tiktok scam page

[cursive inlet]

You could become an astrophotography influencer on instagram and put ads on it. But yeah you have to be good, astronomers arent in it for the cash 😂

[pearl urchin]

you can easily become a millionaire with astrophotography.
If you started as a billionaire.

This hobby just burns money.

[somber stratus]

Syrtis Major my beloved

[somber stratus]

Selling gear is one way, although it's a net loss.

Reminds me, i still have my old Neximage 5 & ASI462MC. Need to sell them

May as well give away the neximage for free though

[livid sierra]

I’ll buy your 462mc

Jk

Better to buy an mm

[somber stratus]

well, 462MC is better than the MM past 850nm

By a couple %, no idea why

[livid sierra]

What about uv

[somber stratus]

much worse, mono is a beast

[livid sierra]

Better to buy mm then

[somber stratus]

correct

[livid sierra]

Sawry man

[lean hearth]

Asi 178mm

Good ?

[sharp ridge]

Very poggers

[livid sierra]

What time & altitude

Local time

[somber stratus]

Early morning planetary hits different. Can't wait to do it again in a few months

[somber stratus]

for what

[cursive inlet]

Jk

Give it to one of those phone imagers

[heavy mirage]

Around 530am PST, 45 N

[heavy mirage]

True that

[somber stratus]

Last year had busy nights with Mars bringing up the rear

Ig we’ll have similar again in September with Venus before sunrise. Really good western elongation.

[ruby tartan]

Give it to @deep island

[lean hearth]

Solar, moon, planetary, maybe ap?

[somber stratus]

Good for moon, but that's about it

Would do ok for the others, but far from optimal

[deep island]

https://tenor.com/view/rock-one-eyebrow-raised-rock-staring-the-rock-gif-22113367

[ruby tartan]

Solar too

[somber stratus]

Rolling shutter isn’t too ideal

[ruby tartan]

Really? I've seen excellent solar images with this camera

[clear pier]

do these venus frames look ok? first attempt ever and without a barlow since i forgot about it

this was with 0 gain 10ms exposure on a uranus c

[ruby tartan]

Clipped the image, try using less exposure

[clear pier]

sorry what does clipping mean?

[steep apex]

Any cool planetary events this year?

[ruby tartan]

got super exposed

[clear pier]

crap that was even only at 10 ms

i guess we go lower next time

[white prawn]

So far a couple of lineups already happened and I was clouded out of both.

[clear pier]

i mean not a horrible first stacked image

[lean hearth]

I was hoping to get a lunt 40mm with this cam and a dob 10-12” for planetary

I saw this paired with the lunt

My main thing I’m saving up for is rn a ha sun rig with a nice mono cam to go with it

[somber stratus]

Venus needs about 0.5ms with a 2x barlow. Bright planet

[clear pier]

damn ok that’s short but makes sense

[clear pier]

hey quick question, what exposure times are good for getting mars?

i know it’s bright but not as bright as venus so do i need really short or maybe longer than .5ms, this will be with a 2.5x barlow, a uranus c, and a 150/750 150p

also is the .5ms for venus still good with a 2.5x or do i need shorter?

[cursive inlet]

Just set the exposure to where it doesn't limit your fps and your gain to where your histogram goes up to around 50% to 60%. And just do this for every planet.

Well not every planet, Uranus and Neptune benefit from sacrificing fps for exposure but yeah.

[clear pier]

i set my gain at 0 for this venus but exposure at 10ms, should i up gain and lower exposure?

also how do i know if my histogram is at 50-60%?

[cursive inlet]

You are using firecapture yes?

[clear pier]

no it’s not working on my mac im using astrodmx

i tried for many days to get firecapture to work but it just could not

[cursive inlet]

I havent used astro dmx but theres gotta be a live histogram option somewhere there

In firecapture it looks like this

[clear pier]

i can see the histogram but not in 3 different colors like that

[cursive inlet]

That doesnt really matter

What fps do you capture at?

[clear pier]

around 34 because my mac is incredibly slow

and that’s at raw-8

[cursive inlet]

hmm

Are you capturing at full resolution or do you do an roi at like 800x600 for example?

[clear pier]

full res

because the click and drag for roi is really buggy i hate macs

oh and im in ser format if that matters

[cursive inlet]

Well the main thing I would worry about is getting a windows laptop or smth, but to solve your current problem, I would set the gain to 0, and then raise the exposure until it starts decreasing your fps or until your histogram reaches 50%.

[clear pier]

lmao ok got it thank you

[cursive inlet]

Cuz like you are really under utilizing the camera with that mac. People usually image at 200 fps or more.

[cursive inlet]

And if you reach the point when your fps starts falling because of the exposure, but you still haven't reached 50%, only then start increasing gain.

[clear pier]

oh wow that’s insane…

[clear pier]

mm ok ok got it

well isn’t having too much exposure not good for bright planets?

[cursive inlet]

too much exposure means clipping your data, if you have your histo down to 50 its not too much.

[clear pier]

ahhh ok got it so if it’s 50% histogram it’s not clipped that makes sense

[clear pier]

did i get this mars frame all right?

this is the raw stacked image of best 1% 😬

also what do you do in autostakkert if it won't place any alignment points?

[heavy mirage]

@clear pier Try rgb alignment next time, and place a big AP to cover the whole Mars.

[clear pier]

yea im trying to do more in pipp rn, and i'll try that actually thank you

[heavy mirage]

Benus

[livid sierra]

What’s that red thing on your scope lol

By the focuser

[cursive inlet]

I think when you dont have a 10:1 focuser, some people attach jar lids or other things that make the focusing finer.

[livid sierra]

Ah yeah I’ve been thinking of that too

https://www.orenelliottproducts.com/product/bd601/ I just found this

Modifying your focuser with this should turn it into 6:1

[livid sierra]

I could attach a lid or something to one of the focuser knobs but the knobs are super close to the tube

@heavy mirage How do you deal with that with that long ass lever on your focuser?

[heavy mirage]

It comes off

@livid sierra

[livid sierra]

Damn that's nice

I should make something like that

[heavy mirage]

3d printed, then super glued metal pins inside 6 small holes

Plastic ones break off too easy

[livid sierra]

I don't have access to a 3d printer but I'll try and figure something out

In case I do find access to a 3d printer lol, can I ask you for the file of the lever?

[somber stratus]

elite

[lean hearth]

Hi

Name a nice Mono Astro cam in a like a under 700 budget ish

[livid sierra]

zwo asi462mm

zwo asi290mm

[lean hearth]

my goal is to take nice moon , planet and sun pics

[livid sierra]

462mm should be alright then

Are you planning to do white light solar or ha

Why mono tho

[lean hearth]

Ha

[livid sierra]

Are you planning to get a mono cam for solar then? You realise you'll need colour filters for the planets then too? And probably a filterwheel unless you're planning to manually switch filters like 20 times per planet

[lean hearth]

I guess so, what type of color filters would I need or would it be smarter just to get a diff cam better for planetary?

[livid sierra]

You'd need colour filters that give you colour, like rgb you know colour

So yeah I'd probably get a different cam for planetary

[lean hearth]

Which cam would you use for planetary in the same budget I gave before

[livid sierra]

Mono planetary is kinda unnecessary anyway unless you really want to squeeze out every detail you can get

[livid sierra]

Uranus-C

[lean hearth]

Heard about that one sounds nice

So I’ll keep it in mind

For planetary I’m gonna try ang get a 10-12” dob and for solar a lunt 40mm

[livid sierra]

Cool

[somber stratus]

Apollo M Max/Mini then

462MM is way too tight

only works for Planetary

[lean hearth]

Ok thank you

[lean hearth]

what’s the diff between mini. Or max

I’m might get the mini it’s cheaper

Sensor size im guessing?

[somber stratus]

Max has twice the pixel size in microns, and twice the angular FOV as a result. Mini is 4.5 microns, max is 9 microns.

Depends on your setup as to which is best

[lean hearth]

Gonna use a lint 40mm

Once I get my hands on both I’ll take nice ha pics

[somber stratus]

What focal length is Lunt 40 again?

[lean hearth]

F10 400mm

[somber stratus]

Mini then.

[lean hearth]

Ah so I’m right to get the mini

[somber stratus]

Should get full-disc coverage, just about

[lean hearth]

Nice

Been a goal for a while to capture nice sun pics

You take amazing planetary and solar pics Tom

I wanna take ones just like you one day

[somber stratus]

400mm FL with Apollo-M Mini (IMX429)

[lean hearth]

Nice

Should I get some sort of Barlow to capture like more in-depth e.g Solar prominences

[somber stratus]

yeah probably

[lean hearth]

what Barlow you recommend?

[somber stratus]

Celestron 3x X-Cel, APM 2.7x, TeleVue powermate 2.5x

[lean hearth]

May I ask what’s the diff with more expensive ha Solar scopes?

Like I see the Lunt capture amazing pictures and it’s like the cheap east solar scope on the market

[somber stratus]

You mean the Quark, or larger dedicated solar scopes?

[lean hearth]

ah that’s it I’m assuming the size is the price difference?

[somber stratus]

yeah, and Quark can be used on any pre-existing refractor.

[lean hearth]

You see the Coronado Solar max reaching like reaching way more

[somber stratus]

Ah yeah those aren't great for the price

[lean hearth]

What you think of the Coronado pst it’s a lil cheaper then the Lunt but I was told doesn’t perform well for a ha Telescope

[livid sierra]

I want that double APM 2.7x barlow

[somber stratus]

it is pretty goated

Might get one later this year

[somber stratus]

meh, Lunt more reliable

[livid sierra]

You gonna get one? Or two

[somber stratus]

Two perhaps. Depends, 6.5x is way oversamped with my 462MM & Uranus-C

[livid sierra]

Two APMs together makes for like 7.3x tho doesn’t it. Add ADC to that and I think it’d be around 8-8.5x even

[lean hearth]

Can whitelight filters show much more then just sunspots?

[somber stratus]

nah, it's a barrel extension that makes it 6.5

[livid sierra]

Oh I thought it’s like two barlows stacked but they designed in some special way that it’s meant to be used that way or something

But yeah I guess the 2 elements combined is designed more for really big scopes like Martin’s 17.5” or Ethan’s 24”

[somber stratus]

Sorry, it's 6.25x

[livid sierra]

Np

[livid sierra]

OP

[heavy mirage]

Yeah for sure, no problem! I actually made one out of cardboard at first, and it lasted for about a year or so. Eventually I needed an upgrade lol

[cursive inlet]

What the faq is happennibg to me

[ruby tartan]

What happened?

[livid sierra]

Are you drunk

[steep apex]

Venus today

[lean hearth]

should i get a solar contium

continium filter

[ruby tartan]

[little quartz]

Im buying a camera to pair with my c8 to do some planetary astrophotograhy and i've heard a lot of good things about the zwo asi224mc. Is there any better options with a similar price, or is the asi224mc the best for the $200-$300 price range?

[hasty hull]

I would go for the PO Neptune-C ii

Sensor size is pretty wide for if you want to do some dso stuff

And does 93fps at the highest resolution

If you crop the roi it is way faster even

[livid sierra]

I can finally do proper-ish UV now

Got the Player One uvir cut to pair with my w47

The ZWO uvir cut cut too much UV

[hasty hull]

Looks insane man

[livid sierra]

Thanks man

[steep apex]

What crater is this?

[somber stratus]

Idk

Just looked cool

[near quiver]

me every time i do lunar

[steep apex]

I wanna image this

[vagrant cliff]

With my 150/750 and dslr +2x Barlow would I be able to image mars even at 5"? Any detail possible?

[sharp ridge]

No way

Lucky to get a disk

If you got a planetary cam then perhaps a Lil bit of detail

[fading plume]

@sharp ridge @somber stratus Thinking of buying a nice barlow and maybe a IR pass (maybe 610nm) for this planetary season and venus elongation.
Celestron X-Cel 3x good or is there a better one? Want this to be a one time investment.

perhaps a powermate

[uneven raven]

Does Celestron ever actually make good products lmao?

[somber stratus]

Yeah, powermates do the job. I use the X-Cel and have no problems with it. The APM 2.7x is also great

[fading plume]

looking for an investment, so X cel i guess? or are there better ones.

or are they all the same

[somber stratus]

Idk. I don’t have them all. They’re all good. Certainly good enough to reach diffraction limit

APM is probably the best optically but it’s very marginal

Also depends on your camera and f ratio as per sampling.

Televue only make 2.5x,4x,5x

X-cel + ADC acts more like a 4.5-5x

[vagrant cliff]

What about Venus at 15"?
Ngl Venus never really has detail

[fading plume]

2.9 microns at F/6 so 3x is pretty good.

[somber stratus]

Yeah I’d say 2x X-cel + ADC, or APM 2.7x or 2.5x PM. Or Televue 3x Barlow (not PM), 3x X-Cel, 3x explore scientific w/o ADC as spacer

But I recommend using ADC so probs one of the first three

[fading plume]

ight thanks. My seeing is shit normally so i have a pretty hard limit, still want to get as good as i can. probs gonna get the 2x xcel then.

[somber stratus]

It doesn’t make a huge difference, just as long as you’re not using some $20 Amazon Barlow

[vagrant cliff]

What about the 5x rule on 150/750 at 3.72pizel size? Should I get a 3x or 4x Barlow?I already have a 2x barlow

[somber stratus]

It's a pretty rough rule. Anything 5-7x pixel size as f/ratio is fine. I'd say 4x, or a 3x+ADC.

[vagrant cliff]

Alr

[hasty hull]

Definitely could get the phase, not sure if any cloud detail would come through

[vagrant cliff]

You can also press Alt+N on Stellarium and it’ll annotate a whole bunch of craters on the planets and the moon

And with Alt+N enabled you can also look them up like any other object

INA with a 16" from a friend

[heavy mirage]

My take on it a few days ago with a 10"

[vestal gulch]

What eyepiece?

[cursive inlet]

💀

[livid sierra]

Lol

[heavy mirage]

fart sound

[livid sierra]

ISS in poop

[heavy mirage]

Would have been good, but I had trouble with the synscan app and sat tracker. Updating drivers etc helped but I'm still having some issues with the tracking. Which is strange because it worked great a few months back

6+ months back

The offset options in sat tracker dont work right, maybe due to the interval between steps

[sharp ridge]

whys the solar panels so bright compared to the modules?

odd

[safe compass]

its technically a mirror

reflects the light better than the modules i think

[heavy mirage]

Possibly they were shaded from that angle

[sharp ridge]

usually its the opposite, panels are usually quite dim and you have to blow out the modules

[safe compass]

Ohh, sorry, didn't know that

[sharp ridge]

the more you know

[somber stratus]

Same

latest version is whack

[somber stratus]

back-illuminated

orange when you view them from behind and they are illuminated.

[sharp ridge]

cool

[somber stratus]

Oh damn, theres a new release. Will test it now.

20th April. Last one before then was September last year

[ruby tartan]

What?

[somber stratus]

Synscan Sat tracker

version

[somber stratus]

what was the specific issue you encountered? was this with Sat track v0.25.0, PreviSat 5.1, Synscan 2.3.3?

Just tested myself now with a test pass and seemed to work fine. The offset is now similar to planetary in the way that you just slew around to centre the ISS - number denotes slew rate. You can't just tap the buttons, you have to hold them to slew. This slew speed is added/subtracted from the normal sat-tracker movement. You can use either the hand controller slew buttons, or those in the sat tracker menu.

[heavy mirage]

When I would try to slew with the offset during tracking, it wouldn't slew in the right direction and there is always some sort of weird movement that happens in the same direction no matter which direction I offset. And the slew speed doesn't affect it either. Only after a few times with the buttons I'm able to properly control it, but once I release and offset again in a different direction or something similar, the problem happens again

I havent tried using the HC for offset, and if it works it will simplify use greatly. However last time i tried, the tracking would stop.

How many steps pwr second are you generating with previsat

[somber stratus]

HC definitely works - I look through my finder scope, and slew to centre it when ISS rises. I used to do 300ms (3.3/sec), but i might drop it further to 500ms. I was also having cut outs where the tracking would just stop.

I think its bc the PC is trying to do so many things at once. Synscan app, wifi, sat tracker, and slew inputs - all that plus running FC and recording the data onto your drive. I might drop the ram buffer in FC too to reserve more ram to the other programs.

[heavy mirage]

The synscan app also has some sort of read timeout settings, which is set to 200ms by default. And I use 2 laptops when doing iiss, one for tracking and the other for capture

[somber stratus]

Interesting. Wifi still or USB?

[heavy mirage]

Yeah, wifi. I heard USB might be better, but meh it worked really well a few times. Just gotta keep trying

[somber stratus]

I tried to do USB just now but its really difficult to connect. It's just as awkward.

Plus will take USB bandwidth away from camera in my case

Doesn't help that the ISS is so rapid 😆

[heavy mirage]

Yeah, don't need more wires when the scope is moving all over the place lol

2 laptops would help maybe

I'll try a test run later and see how it performs

[somber stratus]

I did a test run with wifi and seems to work fine. I might do a whole run with FC recording too.

and slew all over the place too to test that

[heavy mirage]

Good, let me know how that goes. I'll do the same when doing my test run

[somber stratus]

I've got a 85° pass tomorrow morn. Hope i can sort it.

[heavy mirage]

You better not f it up!

Jk lol no pressure

[somber stratus]

SW recommend 20ms for wired, and 200ms for wifi. Still think thats too many points

I was still having issues with 300ms

[heavy mirage]

Maybe adjusting the timeout setting in synscan would help?

[somber stratus]

I have it at 300ms

but idk if that's for initial connection

might bump it up to 500

[heavy mirage]

Idk 2 steps per second sounds a bit sluggish, but it's probably good

[somber stratus]

It's fine if the passes are vertical in nature, i.e overhead ones

that dont change much in Az as the station is rising.

[near quiver]

i have a cool idea, probably already been done

what if you took an image of jupiter, then about 10 hours later (the time it takes jupiter to revolve once) you take another picture? would that capture cloud movement?

[somber stratus]

Yes but two different people would need to image it with similar gear

As Jupiter isn't up for 10 hours at a high altitude for almost all locations - that is except for high latitude regions during high declination oppositions. For example Jupiter will be up for 16 hours in December 2024 for me. Will definitely try such a thing and get a full rotation.

https://media.discordapp.net/attachments/570687129118703637/1008753282988134450/TL2_pipp.gif

Mine & @sharp ridge 's data from last year

10 hours apart

[near quiver]

Ooh that is cool

To solve the time issue, what if you did 20 hours? There would be a bit more change but at least you could do it by yourself

[somber stratus]

50h is the first good overlap

5 Jupiter days, 2 earth days

The ever-changing face of #Jupiter. Using images from this morning, Aug 15th, and Aug 7th, I was able to "time-lapse" the cloud evolution. Unfortunately the GRS was only well-placed on these occasions, so only two frames of animation were possible. #astrophotography

twitter one is ofc 8 earth days = 19 Jupiter rotations, but one above with my 12" is 50 hours.

Tbh if you had excellent seeing, you could probably catch cloud movement inside a 5 hour timelapse of one face rotating. You'd just need to make a map projection and animate it.

[near quiver]

Might try once I get Uranus C

[summer field]

you can do it over the course of a few weeks
here ~3 weeks

[somber stratus]

You are seeing more of the slow moving formations here. Neb & EZ is too fast.

[summer field]

definitely needs more frames, but weather/seeing makes it difficult

[livid sierra]

@cursive inlet Bro how do you do your Venus bicolour colour balancing

I can only get it to look like vomit

[cursive inlet]

Tom said to basically normalise all of the stacks before sharpening. So what I do is in AutoStakkert I set normalise to 60% for all the stacks. Then I sharpen them and then I put em into gimp and colorise.

[livid sierra]

Weird, I do the same

[cursive inlet]

Send me yo stuff I’ll give it a try

[livid sierra]

Sure

[somber stratus]

You can even normalise after sharpening but it's best to do before hand.

[thick heron]

Don’t need more than a few hours with enough aperture.

[cloud copper]

How does normalise help with my images?

[livid sierra]

It’s mostly for when you’re combining several images to make one like derotating or combining UV and IR so they’re all the same brightness @cloud copper

[cloud copper]

Oh, good to know, thanks!

[cursive inlet]

@livid sierra

I used the softer files

I am not sure but I think the lighter background and those border artifacts in the UV and IR stacks were messing up the histogram.

So when you were normalising, it also took in account those artifacts and the 60% wasn't actually 60%

I just took the individual stacks, cleaned them up in gimp and then normalized them again

This would work better actually if you do this before sharpening.

So before sharpening and derotation, you need to clean all your stacks up.

[livid sierra]

Yup

I’m free this Friday so I can spend the whole night tomorrow breaking my head over this one picture to try and get it right

[cursive inlet]

Yeah it took me some time to get it right the first time too

[topaz elk]

astropheric said 0/5 seeing -_-

[somber stratus]

So nice

#1019937457095065731 message literally suggested this a few hours ago

didn't know you actually did it

[thick heron]

I have done it four times from 2016-2018. I should consider digging them back out of the archive.

This one from the night before. MP4 this time so Discord doesn't ruin it (hopefully).

And of course I had to compare the two nights.

[somber stratus]

Very good going for only 2h 30m

[livid sierra]

@cursive inlet I finally did it

Worst 4 days of my life trying to process this lol

[hasty hull]

Beautiful shot

[safe compass]

that is venus?

[livid sierra]

Yeeesh

[livid sierra]

Thanks friend

[safe compass]

hollyy AMAZING!

[livid sierra]

Thank you!

[soft skiff]

Woah absolutely stunning

[cursive inlet]

I know this aint related to imaging but doin some visual rn and I can see some pole brightning with the w47, pretty cool

[livid sierra]

[ruby tartan]

Venus last night

[cursive inlet]

quick uv process from data about an hour ago

[white prawn]

@ruby tartan @cursive inlet what kind of scopes?

[cursive inlet]

We both image with 8" reflectors

[white prawn]

Okay, thank you. I have the same equip then. Got a few shots w/ an ASI585 but it's just a white ball for me. 😦

[cursive inlet]

Venus is mostly featureless in visible light

[ruby tartan]

Nice, i need a UV filter

[white prawn]

What if I'm using a UVIR filter?

[cursive inlet]

UVIR cut is a visible light filter. It cuts uv and ir

With that filter you image in light that you and I can see

[white prawn]

So better to do w/o filter?

[cursive inlet]

No

[near quiver]

no do it with uv/ir cut

[cursive inlet]

Without the filter you would be imaging UV visible and IR at the same time which is bad

[near quiver]

if you have uv or ir filters use them but otherwise theyll just mess stuff up

[white prawn]

I'm going to have to prep/stack data then. Have some shots before the filter, it's just a white ball. I want something that looks a bit like what you guys have. I just got so disappointed w/ the non-filtered result I didn't bother rushing to process anything.

[near quiver]

yeah for the nice contrast you need to shoot uv and ir seperate

[white prawn]

Wait. So the UVIR cut filter will NOT get me that?

[cursive inlet]

UV IR cut means that you are cutting both uv and ir, you are imaging in visible light.

Venus is featureless most of the time in visible light

[somber stratus]

It's actually got similar detail to red & NIR

just lower contrast

[cursive inlet]

Yeah, but to get the good stuff you need specialized filters that pass light outside the visible spectrum.

[white prawn]

That's why I asked if I should image Venus w/o UVIR cut filter, and I thought you said to keep the filter for imaging Venus. Confused now.

[cursive inlet]

You should never image anything without a filter.

Without any filters you capture UV, visible, and IR, which causes weird colors and other problems.

[somber stratus]

OSC

RG610

[ruby tartan]

I think I'll buy a 305mm

[somber stratus]

i mean it's 5 arcsec

lmao

[white prawn]

But if the filter leaves visible light, and Venus is mostly featureless in such light, then that still leaves me w/ a white ball.

[cursive inlet]

If a uvir cut is all you have then use that. But don't expect good detail.

[cursive inlet]

Yes but since you dont have filters that only pass uv or only pass ir, the uvir cut is your only option until you buy the other filters

[ruby tartan]

A 305mm Dobsonian or keep my 8" on the eq5?

[cursive inlet]

dob

get an eq platform if you can

though for 12" it could be expensive

[ruby tartan]

Now I have to wait for someone to sell one

[cursive inlet]

I mean hand tracking isnt that bad but an eq platform will make everything much easier

[cursive inlet]

stacked less frames, less contrast but the detail is a little finer

[somber stratus]

No filter results in a blurry mess. UV, visible light and IR focus differently with most imaging trains. UV/Blue is an absorption band when it comes to Venus, so it's comparatively much dimmer. The visible light will wash any detail out. Similar story is true of IR, except it's camera QE/response that lowers the proportion you detect.

Two choices, use a UV/IR cut, which filters only visible light (very low contrast detail), but at least you can focus right and have a sharp limb definition.

Second choice is to use a UV shortpass filter that only allows UV to pass. You'll detect the absorption band, and clouds with it. Similarly you'd use an IR-longpass filter to catch the best relative seeing conditions (longer wavelengths are less affected), and a touch of the mid-cloud layers.

[cursive inlet]

this

[somber stratus]

305mm OTA on the eq5, of course

[cursive inlet]

💀

[ruby tartan]

https://tenor.com/view/waiting-for-death-gif-19954908

[white prawn]

I see. Since what I have now is UVIR there's a little hope that I'll get something.

[cursive inlet]

tie helium balloons to the ota to make it lighter

[somber stratus]

Correct. Possibly with excellent seeing conditions and specific processing though. Best bet is to get a longpass IR filter - 610, 642, 685, 742, 807nm+ all work.

[ruby tartan]

Remove the mirror to make it lighter

[coarse aspen]

that cloud detail is definitely there

surprised its so good

shooting before sunset helps a lot with seeing i find

thats daytime?

like 30 mins before sunset

[fading plume]

Le imaging train

[ruby tartan]

Same thing as mine, just change the camera

[white prawn]

I can identify ... some things there. But why the level?

[onyx garnet]

it comes with the ZWO ADC if i'm not wrong

[main flume]

[fading plume]

Because the ADC needs to be level

[coarse aspen]

thats a long imaging train

what does it look like in the telescope

[coarse aspen]

its so far out

is the focuser ok with that

[fading plume]

That’s not in focus

The focuser has like 5mm of clearance

[white prawn]

How can it be level when the telescope isn't necessarily level?

[fading plume]

It only has to be horizontal to the horizon

[white prawn]

So what happens when you're tracking? Doesn't the level to horizon change?

[fading plume]

It does slightly.

I’m still getting the levelling thing 100%. I actually think it stays level

[fading plume]

i really need to annoy tom at some time to get a real answer

[fading plume]

Beanus

dada

[normal forge]

I am so close to get a 12" Dobson for lunar and planetary only... i can't get more aperture for 1100€ and this would really be a hugh improvement in aperture ( coming from 6" ).

[uncut glade]

I went from an 8" to an 11" and my mind was blown. Your world is gonna turn upside down my friend, 4x the light gathering power is nothing to play around with haha

[white prawn]

I'd like to get a 14-16" SCT. Basically go to 8x light gathering and 2x f/l

https://tenor.com/view/raccoon-weird-clapping-evil-laugh-gif-9962946

The universe would be at my window!

[uncut glade]

Oh man that would be awesome. Those big SCTs are no joke man haha

[white prawn]

Neither is their price point 😵‍💫 😮

[uncut glade]

TRUE

But man the stuff Damian peach does with em

[white prawn]

Kind of why I want one. Those are awesome sauce. And I'm thinking/hoping if I can do what I shared w/ a DSLR on an 8" imagine what I can do w/ a 16" and dedicated camera

[uncut glade]

It’s a world of a difference and two worlds apart of skill haha. Go in slow, it’s an incredibly intense learning curve

[white prawn]

Check out the "How Started ... How it's going " thread. I've picked up a bit in a short time w/ what I have. 🙂

[livid sierra]

Get a chad dob instead

[cursive inlet]

[soft skiff]

[heavy mirage]

I often find my self rotating it during imaging. I mean it's not a big deal for 1 short capture, but when doing many after another you'll have go start rotating due to the change in Alt

But im pretty sure that with an eq setup. This isn't necessary? (Rotating it, I mean)

[fading plume]

I think if the dob focuser pointed straight up instead of at an angle it would stay level

But because the focuser is always rotated from vertical it’s never right

I think an EQ setup would be worse

[heavy mirage]

Yeah i think you're right, if the focus was straight up it would always be level. And I mean well maybe it wouldn't work with newts on eq mount, but with refractor or scts I think it would work good. Now that I think of it. It would be best if the sct was mounted on a fork mount. Then the adc should always stay level

AZ mount

[fading plume]

It’s a shame I can’t rotate the focuser so it’s vertical.

[heavy mirage]

Could be a cool idea for "imaging" dobs lol

[normal forge]

Because he has the locations for it.
AND i wouldn't mind getting a dobs over a SCT for lunar / planetary.

I mean... 11" SCT for 3000€ vs 12" Dobs for 1200€...

Moon and planets are sooo easy to track manually.

[livid sierra]

Well I wouldn’t say handtracking at 7000mm with a 12” dob is easy

You could image at 3000 or 4500mm, which still isn’t easy, but why bother getting a big dob like that if you’re not gonna get the most out of it

A tracking eq platform would make things easier tho, and still cheaper

[sharp ridge]

yeah 7000mm handtracked is a bad idea, although doable keep in mind you gotta push it for a long time per capture

[sharp ridge]

12 goto dob > 11" sct
similar price but goto

3000euro just the ota lol

[livid sierra]

Yeah, comparing goto dobs to scts of the same aperture definitely makes dobs the better option if you ask me

Downside is that dobs don’t have eq tracking so dso is a bit harder but the sct is just the ota for the same price

Still need to buy an expensive af mount besides it

[cursive inlet]

IRgUV from yesterday

[livid sierra]

Good shit

[sand marlin]

Venus or Mars?

[safe compass]

venus

[steep apex]

Venus

[sand marlin]

Couldnt tell

And don’t tell me you don’t know

[cloud copper]

Jupiter

[bleak oak]

Uranus 🗿

[heavy mirage]

What's the best way to combine this and this?

[livid sierra]

Alyn Wallace or something has a tutorial on it

[heavy mirage]

Great, i'll check it out

[normal forge]

12" Dobs is 1500mm FL or with my 2x barlow a 3000mm.

[normal forge]

I only want the Dobs for high res lunar / planetary imaging and observation. DSO @ 1500mm FL would be great to observe only.

I took this shot with @ 1500mm FL handtracked with the 6" SCT.
The Emirates A380 was on its way from Manchester to Dubai at 11.200m / 37.000ft and traveling at 945 km/h ( according to flightradar24 ).
I guess i can do even better with a Dob. 🙂

[livid sierra]

Yeah so personally I’d either get a goto dob or a tracking eq platform if I were to get a manual 12” dob

But that’s just me

[normal forge]

Yeah but i don't have a mount for a 12" NOR do i want to spend a stupid amount for Go To i don't need. o_O

I mean its like double the price for the Go To feature.

1160€ for the Dobs, nearly 2000€ for a 12" with Go To.

[livid sierra]

You do you lol

[normal forge]

[somber stratus]

Martin Lewis' 2020 Venus data processed by me. Orbital motion ft. nightside. Spans only 10 mins. I'm so hyped for the crescent phases this year.

[somber stratus]

Yay or nay? testing some processing methods to avoid the sharpening artefacts. Again Martin's data. This is just for aesthetics of course.

can't tell if it looks more natural, or less so.

[livid sierra]

Hmm hard to say, as a still picture it might look better since the detail isn't drowned out by the noise

Not sure if some detail is being eaten by the noise reduction though

[somber stratus]

This is basically 5 different shots, with increasing sharpening, masked. Well, all have a stretch applied.

[livid sierra]

5 stacks stacked or something?

[somber stratus]

Nah, sorry. Same raw stack, just 5 processes of it.

So the dayside isn't nuked basically

Least & most sharpened. Idk whether i like the end result though 🤔

[livid sierra]

Like, HDR-ed? I'm not completely following

[somber stratus]

Nightside is sharpened more than the periphery.

[livid sierra]

Have you blended these two

[somber stratus]

There are 4, but yes.

[livid sierra]

If the nightside is just masked into the softer images then I think that might be the better look

[somber stratus]

i can't see another way of getting rid of the black ringing around the dayside.

[livid sierra]

It looks quite clean

[somber stratus]

that's what i did.

Started with the softest, as a base image

[livid sierra]

Yeah then I'd say go for that

[somber stratus]

But if you over-do it, it looks unnatural

it's a fine line

Maybe there is a different way of removing the black ringing. I'm honestly not sure.

[livid sierra]

M. Lewis' looks pretty rough but he don't give af

[somber stratus]

It's tied to the gibbs phenomenon i think. Deconvolution still yields it.

[somber stratus]

Yeah ik, that's the way to show off the detail. I'm just talking aesthetics here

[livid sierra]

Yeah

[somber stratus]

without hurting image credibility

Ig do both is the answer.

One for detail, one for aesthetic

[livid sierra]

Yeah, your method you demonstrated above seems like a pretty nice approach

Maybe see if you can perfect it some more in some way

But it looks good, and let's be real the people on ig will think it looks great anyhow

[somber stratus]

Also this is a single stack, 4mins. I think with all 71.5mins that Martin used, it might look much nicer.

I still have lots of noise.

[livid sierra]

The 20-30min rotation thing doesn't apply to the surface on Venus right?

Just to the atmosphere

[somber stratus]

Yeah, you can do stack of stacks for any given imaging session. You derotate over several days of data.

Martin's above is May 2nd-9th

derotated to the 5th

[livid sierra]

Ahh right, yeah we talked about that earlier

So plenty of data possible to be collected

Given the weather cooperates

[somber stratus]

It's quite ludicrous though, taking data spanning a week.

funny

[livid sierra]

Yeah it's genius tho

[somber stratus]

lucky Venus spins slowly

[livid sierra]

Yeah lol, works out for this practice

[somber stratus]

Although annoyingly 1 Venus-Earth synodic period equals 2 Venusian days (rotation). End result is an extremely rare synchronisation such that we only ever see the same surface features for a given eastern/western apparition. Eastern elongations have Beta Regio prominent like in Martin's 2020 data. Western elongations have Aphrodite Terra visible. Anything between these two longitudes are very hard to spot, if at all.

[livid sierra]

That's a shame

[somber stratus]

The chances are wild. It's practically exact.

[livid sierra]

I mean

In a few thousand years

I reckon it'd be shifted so it's visible right

[somber stratus]

Wait no, it's not synodic period. I'm dumb. It's something along those lines. Years/rotations/synodic period.

End result is the same. Can't remember exactly how it arises.

numbers above give 243*2 = 486, not 586.

It's 5 Venus solar days = 1 Venus-Earth synodic period. Got there in the end.

[coarse aspen]

wait thats the night side of venus? i had no idea that was possible

[somber stratus]

Yeah. Martin Lewis' data from 2020. I plan to get something similar in June/September.

It's narrowband 1010nm thermal emission from the surface.

[near quiver]

i think ill do saturn in the morning, my first image of saturn this season

actually i think that will be my first saturn image with the 224

ooh just noticed youll be able to see the shadow of the rings now

i guess i could also try jupiter if i feel lucky but i dont think ill do that

actually iss too

[somber stratus]

Jupiter's a bit of a stretch currently

[hasty hull]

8deg altitude at sunrise

[white prawn]

Yeah. Tried getting it in Feb and it came out looking like pastel painting. I'm told that getting an ADC would help.

[near quiver]

yeah i see that. i have a decently low horizon there but even still idk if that would be worth it

[safe compass]

All of planets are unavailable now until December or so 😭

[livid sierra]

Jupiter and Saturn become early morning objects around June/July

Saturn opposition is on August 27th

[safe compass]

Early morning?!

Nahh, no way lol

[thick heron]

Early bird gets the gas giants.

[safe compass]

:(

[livid sierra]

I mean it’s gonna be summer break soon

I might have my last week at my internship next week or the week after so I’ll be on break til September

You bet Imma be inverting my whole sleeping schedule to get those suckers at 4am

[safe compass]

Lmao

[somber stratus]

December? What is this, leisure planetary 😆

Summer all-nighters are the best part

[pearl urchin]

Also Venus is up🤔

[livid sierra]

Leisure planetary loool

[livid sierra]

Fr dude I can’t wait mannnn

I swear if the weather this summer is gonna suck ass I’m gonna be so disappointed

[safe compass]

Huh, or so I'd read in telescopius, lemme read sorry

The reason I said they are not available is because they hit the horizon before it gets dark.

[livid sierra]

Go to Saturn or Jupiter in Stellarium and go to like June 10th or something, just a random date

You’ll see that they don’t

Maybe July 10th

June 10th is a bit too early

[somber stratus]

Exam period is also up for most people

[livid sierra]

@safe compass

[safe compass]

So telescopius isn't accurate lmao

Thanks though

[livid sierra]

Idk I never used telescopius

[near quiver]

I got up but it was cloudy

[safe compass]

It allows accurate framing even idk if it is, and allows you see when deep sky objects are visible or not and such but they suck for planetary apparently

[livid sierra]

Stellarium does the same thing

[safe compass]

Not for mobile apparently

[livid sierra]

Yeah you have to pay for it to do framing

On desktop it’s free tho

[safe compass]

Is it even worth it

[livid sierra]

Ngl I’m paying for it

I’d say it’s worth it

[somber stratus]

Desktop version>

[hasty hull]

day after my bday

[livid sierra]

Haha no planets for you ma boy

[somber stratus]

Shame Venus drops in declination so rapidly as it approaches inferior conjunction in June. Or rather is placed south of the ecliptic - never too high after sunset. We've passed the peak altitude observed at the moment of Sunset.

Will be well-placed again in September though i guess.

[safe compass]

I forgot, how do you calculate fov? I wanna check how planets looks like with my 700mm frac

[livid sierra]

Gonna require to get up in the morning lol

[livid sierra]

You open stellarium input your camera and telescope properties and read the values in the upper right corner lol

Very ez calculation

[thick heron]

Flashbacks to my Summer 2020.

Jupiter, Saturn, Neptune, Mars, Uranus, Venus.

Did that pattern every night until sunrise or clouds came in.

[somber stratus]

2020 was so useless for me

declinations were too bad

not that i had much skill or enthusiasm at the time

Wasted away the Mars 2020.

[thick heron]

UK moment.

Just go to Barbados.

It’s that easy.

[somber stratus]

Or go to Texas and steal a 24" Dob from an unsuspecting owner

Then go to Barbados

[cursive inlet]

https://tenor.com/view/mujikcboro-seriymujik-gif-24361533

[somber stratus]

What will be odd is having Jupiter for 6 months, then Saturn for 6 months around 2030. I've only ever known it be in the same season.

[livid sierra]

Am I tripping or is Tom's name two different colours in this screenshot

It looks brown in the lower message and orange in the upper message

[cursive inlet]

optical illusion

[livid sierra]

Yea wtf

It's my stupid monitor

[cursive inlet]

Ethan's name in the reply is darker maybe thats why

[livid sierra]

Because it's higher than my other monitor

Ok I'm not tripping

[cursive inlet]

wait

your screenshot doesnt have "Then go to Barbodos" after the chad gif

[livid sierra]

Lol no tf it came before the gif in my screenshot

Odd

[somber stratus]

just depends which your client picks up first. We sent at basically same time.

[thick heron]

I miss always having one of the two in view ten years ago.

Should move to Barbados and rent out time on the 24” to others.

[somber stratus]

Yeah, only good if you're near the equator, or at least the tropics. 2031 is terrible for Jupiter up north, so it may as well be 1 visible.

I need to move to La Palma or something.

50N is just pain

It's not so much the clouds, but the altitude, and limitation of half of the apparitions.

Luckily i've avoided the recent string of poor apparitions. Only caught the tail end of Saturn's low declination.

God help me if I took interest in planetary imaging before then...

[thick heron]

I wouldn’t mind somewhere else. There are obstacles for most of the year except summer. We’ve been lucky the past few years because most planets have been visible in the summer but that is becoming less true.

[somber stratus]

Just pool income and live in Barbados with multiple monster Dobs.

Sounds like a plan to me

[thick heron]

I haven’t had the EdgeHD 14 out since early-January.

[livid sierra]

I'd be down to go on a trip with some dobs and cars someway sometime

We'd need multiple people with a car and a driver's license tho

I have a driver's license

[somber stratus]

What would be the aim.

visual?

can't drive to the tropic of cancer

[livid sierra]

Lol

Surely there are other places that are nearer that exhibit at least a little better seeing than our home places right and I think it could be fun to meet up with some people

[thick heron]

I could

Mexico here we come.

[somber stratus]

Pic Du Midi observatory is about the closest.

That area.

[thick heron]

Recreate that shirtless picture of DP from way back.

[somber stratus]

Yeah, but do it permanently, year-round

that photo is so goofy

[thick heron]

I probably couldn’t legally drive in Barbados since they drive on the other side from us.

[livid sierra]

Think that'd be a problem? I think I'd be free to drive in England and they drive on the other side too

Don't think you need some special kind of license or permission for that, not sure how it is in Barbados tho

[somber stratus]

Fairly sure it's legal, you just need to apply for an international license.

I won't have such an issue

[thick heron]

Looks like all visitors have to apply for a permit to drive in Barbados.

Not sure if there are country-by-country requirements.

[livid sierra]

Is that the same in England then, do you know that Tom?

[somber stratus]

No clue.

[thick heron]

https://www.gov.uk/driving-nongb-licence

[thick heron]

Imagine the cost of transporting a 24" dob to and from a Caribbean Island.

It's very big.

It's very heavy.

[livid sierra]

Just put it in a rowboat

[thick heron]

I remember someone in Barbados catching one of Saturn's minor moons just outside the rings.

https://www.cloudynights.com/topic/698447-unknown-object-orbiting-saturn/?p=10063587

[white prawn]

I need to move to the Caribbean

[somber stratus]

I assume that's not the F ring too.

SCT ringing.

[thick heron]

Probably not F-ring.

[somber stratus]

I got this last year. Queried Janus, but the SNR isn't really good enough to conclude.

Seeing was pretty ass, so I doubt it. Looks too sharp.

[livid sierra]

Processed my last data from April 30th. This time with ir850 for IR, instead of 610nm

[cursive inlet]

Juicy stuff

[livid sierra]

Ye, I don't really like that thick white edge caused by the lower resolution of the ir850 though

[indigo oak]

Anybody trying for the jupiter occultation?

[cursive inlet]

Realistically though, I know atleast you, me and Tom live within 3 timezones of each other, maybe we could do an online imaging party or smth cool like that.

[livid sierra]

I’d be down for something like that

[cursive inlet]

They aren't gonna touch were I am but might get a cool shot or smth. Evening and really low in the sky though so idk.

[livid sierra]

When is that

[cursive inlet]

May 17th

[livid sierra]

They only get within like 2.5’ of each other for me

[hasty hull]

Weather permitting yes. Jupiter enters occultation at around 30deg, so it’s pretty optimal for me

[near quiver]

ill have a great view of it assuming clouds dont ruin

[hasty hull]

IR Saturn just now

[somber stratus]

Next time you image, try a combination of 610 & UV/IR cut. i.e 610-700nm.

Curious if it'll improve it.

It definitely will if you don't have an ADC.

[hasty hull]

I did get a usable uvir cut capture

Duif processed my data and ended up with this composite, im going to try to make one as well when I get home from school later

[somber stratus]

No i mean stacked filters

610 on its own gives 610-1000nm ish.

610+UV/IR gives 610-700nm

Much tighter bandpass, should have better diffraction limit (on average), and is much more resistant to dispersion at lower altitudes.

You lose a bit of signal though, granted.

[hasty hull]

Oh, misinterpreted

Yeah that would be interesting, tomorrow I have clear skies again

[somber stratus]

I've only done this on Venus, and intend to when i image Saturn

just curious what you would get

[hasty hull]

I’ll give it a go

[somber stratus]

If you don't have an ADC then it'll almost certainly be improved.

[heavy mirage]

I'll have to try that out sometime as well, maybe my Venus will improve lol

Might be perfect for Uranus too
