Planetary Imaging

[cloud copper]

Yea

[cloud copper]

this is the unprocessed stack:

Can you help me get some better results? @livid sierra

[livid sierra]

I’ll try

[cloud copper]

thanks!

[livid sierra]

Looks pretty similar lol

What was your setup

[cloud copper]

I have a 6" newt and for the video I've used my phone

[livid sierra]

Oh not bad then

[cloud copper]

yea

its decent

looking forward to buy an astrocam

svbony sv205

got this image with copernicus too

Capture of lesser known crater Pitatus and Hesiodus

[near quiver]

Lmao just remembered that I shot venus during the Jupiter conjunction

It’s on visual light so it won’t be good but I’ve never done it before

[cloud copper]

lets see it

[near quiver]

I’m processing

[cloud copper]

oh ok

[near quiver]

Jesus I haven’t processed planetary in a few months, I’m very rusty

[livid sierra]

Captured Uranus together with Titania, Ariel and Oberon.

• R+IR 610 longpass: 20% of 94k frames
RGB: 20% of 8.5k frames
• 12” Dob, 3x Barlow, ADC, Uranus-C @ 6900mm f/21.6

[ruby tartan]

A very nice region, there is a crater inside another

[near quiver]

How are you not nerd

[livid sierra]

Idk man they hate me

[near quiver]

@bleak sierra have a look at this

[livid sierra]

Damn it I accidentally gave him a call lmao

Sorry Thomas my phone tripped

[bleak sierra]

@livid sierra welcome to nerd 😄

ir cut or ir pass for lunar imaging

[ruby tartan]

ir cut

[near quiver]

well heres my venus image

didnt turn out great

[ruby tartan]

Do an RGB alignment

[near quiver]

fair

im gonna process this lunar data first

[cloud copper]

looks great !

[livid sierra]

Thanks mayn

[nova delta]

What focal length? That’s beautiful

[topaz elk]

2400

[livid sierra]

What

How about IR 610nm for lunar

[cursive inlet]

Depends on the conditions

When the seeing is bad ir pass will be better but visible light always has higher potential when the conditions are good

[livid sierra]

Ic ic

[somber stratus]

For a 12" & Netherlands average seeing, it'll be IR610 in like 90% of cases

[livid sierra]

Yea makes sense

[near quiver]

im low key tempted to buy a 462mm for lunar

i probably wont but i want to

[somber stratus]

What do you have currently? @near quiver

[near quiver]

asi224mc

[somber stratus]

Ah ok, might be worth for lunar. Mono IMX462 is great for Venus imaging too. Certainly wouldnt be a waste.

[flint veldt]

Man i dont have any thing to say but ur the best planetary imaging in the world ❤️

[near quiver]

makes sense. im saving for a deep sky rig right now so it will probably be a while, but ill look into it. especially since when i get my dso rig ill be using the 224mc as a guide camera a lot

[somber stratus]

Although it's already March so might be worth waiting for the Player-One version of the IMX462

[near quiver]

when does that come out? im waiting a few months anyway

[somber stratus]

Generally they are more stable & have passive cooling etc etc. Idk, your choice though

Like a month last time i checked

[near quiver]

oh ok ill probably do that then

and looking at their track record, theres a good chance its cheaper as well

[somber stratus]

Model is Mars-M II (IMX462) i think

Doesn't show on their website yet but they made a post about it a while back

[near quiver]

i have a cool project ill be doing over the next few weeks/months, i want to image every apollo landing site

should make a cool poster

then i guess in a few months ill redo it with a 462 hopefully

ok reprocessed venus

still want to do rgb align

fixed

[fossil schooner]

im legitimately beginning to become kind of embarrassed by the fact that im not nerd yet because ive been here longer than a significant amount of people

since october 4 2021

of course i havent taken as good of photos as some of you guys, but i dont think theyre too bad

[knotty salmon]

@somber stratus @sharp ridge How do you two sharpen lunar images?

When I do, it gives me this weird pattern

[sharp ridge]

send ma the stack

[sharp ridge]

imppg + lil astrosurface

[molten kettle]

I should like defo be a nerd

[onyx garnet]

de ducc has joined the chat

[cursive inlet]

Just get a planetary cam

planetary the art of imaging planet

[random pecan]

Dude that is a fire background

Lyaphine is my idol

[hasty hull]

Mars tonight at like 8”

[onyx garnet]

Same

[hasty hull]

Pythagoras Crater

[hasty hull]

Venus earlier, no UV just visual wavelengths. I’m very interested in this large yellow cloud structure(?) @cursive inlet @somber stratus does this seem like valid detail? I’m questioning because I was unable to get UV data to confirm

the stack

[cursive inlet]

Sure looks like it

The dark band is definitely detail

[hasty hull]

Awesome

[cursive inlet]

Also visible data usually shows detail similar to what you would see in IR rather than UV

Those bands are very common in IR they are in my images all the time

[hasty hull]

Neat

My 610 is still back ordered, hoping to have it soon

[cursive inlet]

610 is good but your gonna want something like a 742 or 850+ for venus to get some really nice stuff.

610 works tho, if you don’t wanna buy a whole other filter for one planet it should work fine.

[somber stratus]

Yes. Seen it in 3 separate captures now

Appears to be in the green/red part of the spectrum which is particularly odd for something like Venus

green especially

[fading plume]

🅱️enus at 48°

Mars at 7.8" tiny af

[cloud copper]

venus with my small 6" telescope and my phone. Stacked 860 frames out of 7000.

this is my stack if some one wants to help me process this planet

[cursive inlet]

Some nice IR last week

[ruby tartan]

Damn

[somber stratus]

looks like UV ngl

Edge rind makes it confusing ig, makes it look like absorption within the disc.

[cursive inlet]

Yeah, but even in IR can't really expect anything other than some dark bands with 8" and Venus's current size

I'd say this is pretty decent for what it is

[somber stratus]

Yeah, just doesnt look like the typical IR detail, that's all. Not denying it, just looks like UV by coincidence with the dimming towards the terminator & at the equator.

IR is usually those triangular-like belts of ~uniform brightness

[cursive inlet]

Yeah it kind of does

A lot of sharpening was needed so it looks pretty cooked

[somber stratus]

yeah, is normal

Did you grab any Violet/UV that session?

or just IR

[cursive inlet]

I did uv too but im like really sick rn I have no energy to process anything

currently laying in bed

[somber stratus]

If you can stack them i can have a go in my spare time

[cursive inlet]

When I get better I might try doing the usual IR(g)B but also with a less sharpened IR as luminance for a more acurate planet shape

[cursive inlet]

ill send you them tomorrow

[cursive inlet]

bcs the sharpening eats away at the terminator so the phase looks inaccurate

[somber stratus]

Yeah, although IR lum is kinda bland I've noticed. Brightens the areas of UV absorption.

whereas a 50/50 blend doesn't.

[cursive inlet]

Ill experiment with some different combinations, maybe a less sharpened IR for green

[somber stratus]

Upper left is normal combination.

Middle column shows IR lum, and UV lum.

[cursive inlet]

These look very nice

an interesting take on Venus definitely

[somber stratus]

UV lum looks pretty neat but you have to get supreme seeing to make UV-Lum work

• SNR

IR Lum is very bland and unnatural imho,

[cursive inlet]

The L= uv67%+IR33% looks interesting

[somber stratus]

yeah definitely. But again, won't be as sharp as you're including more UV, and less IR as Lum

On most days & average seeing*

[cursive inlet]

Yeah I guess it depends on your data

@somber stratus The white streams are UV or IR data in the LRsGB?

[somber stratus]

White is technically "no feature". The orange signals UV absorption, i.e reduced intensity of blue channel giving rise to a orange hue. White is equal brightness of each channel - no UV or IR absorption.

[cursive inlet]

Rs is synthetic red?

Or smth else?

O wait is it sG?

that would make more sense

[somber stratus]

sG = synG yeah

it's R-G-B = IR-sG-UV

[somber stratus]

tfw Venus is Neptune

UV-SynG-IR

[quick umbra]

what's that?

[somber stratus]

Synthetic Green channel. 50% UV + 50% IR in most cases

[quick umbra]

ooooh

[cursive inlet]

@somber stratus yo I have a question. The deeper you go into IR, the less resolution you get, but is it the other way around with the smaller wavelengths like violet and UV? Would it make sense to use a violet filter to attempt to resolve Ceres’s disk or Vesta’s elongated shape?

[somber stratus]

Blue filter, maybe. UV has too bad signal.

[livid sierra]

I reckon what you can get with the blue channel as is is probably most you can get already

I doubt you'll get more resolution shooting in shorter wavelengths the same way longer wavelengths make for smaller resolution

[thick heron]

It’s a trade-off. On one hand, shorter wavelengths allow for finer resolution given the same aperture, but they are more susceptible to turbulence.

I only see blue as the sharpest channel in great conditions, maybe at least 9/10 seeing if you want to put it on a number scale. I have never seen UV be the sharpest channel, both because of seeing and less signal picked up by the camera.

[cursive inlet]

I guess you would need 9/10 seeing either way when attempting minor planets and asteroids.

[livid sierra]

Would definitely be best case scenario yea

[cursive inlet]

Tried smth a little different

dunno how I feel abt it

Looks good and strange at the same time

LIR(g)UV

Heavily sharpened IR for Luminance

Cleaner less sharpened IR for red

You definitely get a lot more emphasis on IR with this approach, that dark northern band is all IR.

Data is from Feb 27th btw

What do yall think?

[heavy mirage]

Looks neat!

[sharp ridge]

vry nice result

Good for lower aperture telescopes i assume

[cursive inlet]

Yeah for 8” its not bad. Venus is also still pretty small.

[somber stratus]

Doesnt look sharpened enough considering the edge rind isn't blown out

or did you mask the edge

[cursive inlet]

Yeah I masked it a little bit. I gotta say the look is growing on me, luminance as sharpened IR makes for an interesting color palette.

It also makes the image look more detailed, I mean compared to my past two images, this one’s definitely the best.

[somber stratus]

I tried it on mine but looked horrendous

[cursive inlet]

The main reason a did it this way is because the sharpened IR as the red channel was giving me a lot of blue that I was having a hard time balancing out. Maybe this only works with poor data.

[covert needle]

Opinions on processed data with my p1000? (The mars one was during 2020 October approach) but I get these weird processing artifacts even when I redo them.

[hasty hull]

They look nice, when is this Jupiter from

Were these taken at the same focal length, the mars looks much higher resolution even tho it was like half of Jupiter’s angular size

[cloud copper]

What filters do you use to be able to see the clouds on its surface ??

[cursive inlet]

Filters that pass uv light or ir light

[cloud copper]

any filter that does that will work?

[cursive inlet]

For this image I used a W47+IR block for uv and a 850nm for ir

[cloud copper]

or do you need other filters too?

[cloud copper]

Thanks

[covert needle]

I’m not sure, I’m amazed mars photo but I sadly can’t locate the data and mars was at opposition

[cursive inlet]

You gotta have a planetary camera tho, and at least 6” of aperture.

[cloud copper]

I have 6" in aperture and I will buy a ceres-c camera soon, is the cam good for the job?

it has an IMX224 with 150 fps at the biggest resolution

[cursive inlet]

Yeah it should work but I would get a different IR pass, smth like 685nm pass

[cloud copper]

ok, sounds good, thanks

[obtuse yew]

Thinking about going for Ceres this morning. Is it a hopeless pursuit with only 10 inches of aperture?

[cursive inlet]

its at about 0.80" so its pretty big. With 10" the most you could probably do is image it next to star and observe how ceres has no diffraction pattern compared to the star.

Therefore confirming it as a disc rather than a point of light

Ceres is really low in contrast, so resolving any detail is pretty much impossible.

The most ive every seen people doing online with minor planets/asteroids is resolving Vesta's oblate shape

[cursive inlet]

what cam do you have btw?

If you have a color cam then I would run the SER through PIPP and create a monochrome SER using only the blue channel

This will maximise your chances of getting anything

If your seeing is bad then I wouldn't bother attempting resolving a disk, just do a widefield animation without the barlow, those are also pretty cool.

[obtuse yew]

I have an ASI385mc

[polar sequoia]

nice! your mars is way better than mine on the p1000 but your jupiter could use some derotation or shorter subs

I took 30k frames of jup for one single image lmao

literally diffraction-limited jupiter

77mm of aperture and over the rayleigh limit

[onyx garnet]

with the p1000?

[polar sequoia]

yep

[onyx garnet]

Sheesh

[somber stratus]

Edge rind is powerful on this one

[polar sequoia]

whats that?

[somber stratus]

Limb brightening on the left edge

[livid sierra]

It looks like an hdr Jupiter

Cursed Earth shine Jupiter

[covert needle]

Try imaging planets when they are dimmer and closer! Mars has an opposition every year I think. Not sure abt the other planets

Saturn with the p1000 has no detail, how do I fix that (not in processing)

[onyx garnet]

the p1000 can get the Cassini division wth

is it your photo?

[covert needle]

THE STACK IS 3000 frames

[onyx garnet]

a

[covert needle]

Should I do lucky imaging

[hasty hull]

Could you send over the stack

[covert needle]

I lost all of my data from 2021-2020 on the p1000 because where I kept them flooded and they got corrupt

I think I’ll try shorter subs or exposures

[livid sierra]

The other way around

Mars is every two years the other planets once every year

[covert needle]

Oh

[obtuse yew]

https://www.highpointscientific.com/apertura-ad12-12inch-dobsonian-telescope-ad12

I think this is going to be my upgrade for the year. 12 inch f/5 untracked dob. I can't splurge on tracking this year. What other options should I be considering in this price range? I always assumed I'd just go for the apertura but I'm open to other options

[jaunty flame]

I’d heavily consider getting a truss

[obtuse yew]

Also is there any way for me to get a decent coupon code for highpoint scientific?

Purely due to portability? I'm not overly concerned about it and I'd prefer the collimation stability tbh

[jaunty flame]

I’ve got a 12” solid tube and it’s a bit of a pain in the arse to move

Not really a one person lift

[obtuse yew]

Mainly what I'm asking is am I getting good optics here? Or is there a better brand?

[livid sierra]

Just my personal opinion but Idk if it’d be worth it to get a 12” dob if you’re gonna use it to handtrack

[obtuse yew]

I currently do it with my 10 but I get what you mean. Is the jump going to be significantly worse?

[livid sierra]

Tracking at high fl like 7000mm will be a pain and tracking at something like 3000mm won’t allow you to get the most out of it

Unless you’re planning to get a tracking eq platform for it later but at that point you might as well just go for a normal tracking dob

Just my two cents

[obtuse yew]

Worth considering. Thanks for your viewpoint

[livid sierra]

For sure

[obtuse yew]

It just sucks that it's literally double the cost to add tracking

[livid sierra]

Yeah handtracking at 7000mm won’t be fun

[obtuse yew]

I currently do it at 3750mm and this would be jumping up to 4560mm

I honestly think it will be workable for me

Is a 4500mm focal length a far cry from getting the best out of 12 inches of aperture?

[livid sierra]

What cam are you using?

[obtuse yew]

If I did my math correctly it looks like I'm getting 44% more light collecting area in exchange for 21% more focal length (so 21% more tracking difficulty?)

Just thinking out loud here. I like the tradeoff

I have an ASI385mc

Likely to upgrade to the Uranus-C

[livid sierra]

For the Uranus-C you’d be at the correct sampling rate following the pixel size * 5 rule but I know no one who actually follows that rule religiously

[obtuse yew]

Great information to know

[livid sierra]

Most people oversample, so just imaging at a higher fl than that rule would tell you

For the Uranus C you’d stick around f/14.5 but I image at f/21.6 with my Uranus-C and most people do that or higher

I’d just go for the highest fl you can reach

[livid sierra]

12” dob too btw

[obtuse yew]

Also to be totally clear, I'm likely to add tracking to this scope myself. Good DIY skills and it seems to be easy to do for less than the $1200+ additional surcharge

I don't have a need for true go-to. Just cancelling out the Earth's rotation will work for my needs

[livid sierra]

Ah, well if you’re sure you can do that in the future and don’t need it right now I guess the manual 12” could be a good option then

Just one more thing. Are you sure you want to upgrade to a 12” if you have a 10” right now?

Or do you think 12” is the biggest you’d be willing to use, also taking into account setting it up and stuff like that?

[obtuse yew]

Eventually I'll be going for real aperture like 16-20. I'm willing to deal with the inconvenience of a massive scope. At that time I will splurge on true go-to, but that won't be for several years. For now the $500-600 upgrade cost in exchange for brand new optics and 44% more light collecting power sounds worth it to me. I bought my current 10 inch used and it's definitely been loved...I'd like to start again with fresh optics and keep it in perfect condition like I have my eyepieces, filters, and barlows

[fossil schooner]

i have this scope

[polar sequoia]

my shot

[onyx garnet]

Damn

[polar sequoia]

about 2k frames iirc

no derotation

[polar sequoia]

looks like a focus issue to me

could also be -3/5 seeing

[somber stratus]

Yeah unlikely to be limited by seeing unless it’s atrocious with 76mm aperture or whatever it is

[polar sequoia]

77mm aperture yea lmao

but tbf the rayleigh resolution is still decent

[polar sequoia]

you can get a reasonable amount of detail with a 77mm and 30k frames

I could def see difference between 500 frames and 1k in terms of seeing induced blurryness

but that just looks unfocused

[covert needle]

Might have been a little of both

[livid sierra]

Imaged Venus in IR-RGB yesterday around 15:30. Pretty happy with my first ever attempt imaging Venus

Don’t have a UV filter sadly cuz I think I could do a nice IRsynGUV image

[cursive inlet]

Very nice

[cursive inlet]

You can try doing an rgb capture and only using the blue channel in PIPP

You might get a little detail from the uv/blue part of the spectrum

[livid sierra]

With or without uvir cut?

I tried doing that with rgb data yesterday but didn’t get much

Might try again later today thou bc I think I should’ve done it differently

I was thinking of getting a Violet filter and IR cut filter (the zwo uvir cut I use cuts off before 400nm sadly) but I changed my mind and I decided to just buy a real UV filter at some point

[cursive inlet]

With the uvir cut but when stabilising in pipp you select the option to create a mono SER from only the blue channel

[livid sierra]

Ye

[cursive inlet]

Make sure you get a mono cam too cuz you cant use those real uv filters with an OSC

[livid sierra]

Oh that don't work?

[cursive inlet]

Yeah if you have an OSC you need to use the w47

Osc cams are shit at uv thats why you gotta use a violet filter

[livid sierra]

Damn man that sucks

I don’t think I wanna do that

Think I’ll wait until after summerbreak when I’m done with this underpaying internship

When I’m starting uni and I can get a job on the side

Maybe I’ll save for an asi462mm or sum

I’ll think ab it tho

[cursive inlet]

Or you could get the w47 for a few bucks.

The difference isnt that big to justify buying a whole camera and a €100+ filter in my opinion

[livid sierra]

@cursive inlet what IR cut do you use? I could find no uvir cut that doesn’t cut before 400nm and the only IR cut I could find was expensive asl

[cursive inlet]

I bought a seperate astronomik IR cut that passes up until around 370nm.

But if you dont feel like spending the extra 40 bucks or so you would probably be fine with the ir/uv cut I presume you already have.

I mean like you saw my post, the w47 is good enough. I image with an 8” and plus Venus still isnt very favourable, your results with the 12” should be even better.

[livid sierra]

Hmmm yeah I guess

Maybe I’ll get the w47 and IR cut. Could still get the asi462mm and U filter later down the line. Cuz yea the w47 isn’t that expensive I gotta give it that

I wanna get some Bob’s knobs for my secondary too. Maybe I order them together

If I can find them in the same shop

[cursive inlet]

Instead of the u filter i’d spend the 100 on smth cool like a ch4 filter

Those are very interesting on Jupiter

[cursive inlet]

Like I’ve even seen ppl get decent details with a simple blue filter. Getting deep into Uv isn’t really a requirement

[livid sierra]

I’ll be home in a bit. Can check it out then

The ir cut

@cursive inlet https://www.astroshop.eu/blocking-filters/astronomik-1-25-ir-blocking-filter/p,16754 This one yours?

[cursive inlet]

Yup

Got mine for cheaper tho

Astroshop sometimes has some stupid prices

[cursive inlet]

Getting some Venus in a few minutes

[hasty hull]

Sweet

[livid sierra]

Good shiet

[heavy mirage]

Venus, 1 stack with 807nm. Still working on processing the rest

cheap #47 filter + uv/ir cut

[fading plume]

neptune at home

[heavy mirage]

and 642nm. Gonna try to make UV(synG)IR image and see what happens once I stack and de-rotate the rest

[craggy wasp]

Is that a dob?

[tulip nova]

My first post here; Venus and Mars captured last night with an Edge 11", ASI290MM with a R685 filter, ADC and 2.5x Powermate.

[livid sierra]

It is

I feel like the majority of people here image with a dob lol

Or it’s about even

[craggy wasp]

Yep, i'm about to buy a dob lnao

[livid sierra]

Which one?

[cursive inlet]

When exactly did you image? If it was around the same time as I did it would be cool to compare.

[left spindle]

Saturn (old data) also anyone who can process better plz do so. Equipment-
4.5in reflector (untracked)
webcam

[near quiver]

I’m no expert but that looks like Saturn

[left spindle]

yeah sry ill correct it

[somber stratus]

807 is a great one for IR captures

probably optimal for Venus

850's a bit deep so you lose res, then <685nm is too featureless.

[heavy mirage]

3-4UTC on March 17

[cursive inlet]

Oh about 12 hours off, nvm then

[heavy mirage]

When looking through the data, it looked like 642 had similar/better results than 807.

Affected more by seeing though which makes sense. while 807 is less affected

[somber stratus]

Yeah, majority of the time 807 will beat out the 642. The atmosphere of Venus has more details regardless of seeing.

[cursive inlet]

@somber stratus what filter do people use for thermal Venus surface imaging? Does any 1000nm filter work or is it a specific one?

[heavy mirage]

Lol true, not like the resolution is that much different between 642 and 807

Stupid uv though, resolution is ass/ seeing effect

[cursive inlet]

Fr

[heavy mirage]

But yeah, I could use another filter in the 700nm range

[somber stratus]

I believe it's the edmund optics 1000/25 or 1000/50 filters. They aren't 1.25" so not sure how you mount them. Quite expensive too.

[somber stratus]

Yeah in terms of sharpness, they'll be pretty similar. 642 has better diffraction limit but good luck using it at ~30° altitude.

[heavy mirage]

true that

[somber stratus]

Some funny hubble data

Ganymede was a pain to correct for

R,G,B captures 4 mins apart. 10-Feb-2016

[cursive inlet]

Finally some decent UV

[somber stratus]

This actual UV, or your Violet+IR cut?

looks decent

[cursive inlet]

its the w47

Is it correct to call it uv?

i mean like everyone else does

[somber stratus]

Yeah it's got some UV passage. Was asking if you got a designated UV filter as the contrast looked pretty decent

W47 is blue+NUV, so yes you're correct, but by "actual UV" i meant a filter similar to mine which passes no blue (>400nm) light.

[cursive inlet]

I have an osc, dont think that would work with a U filter

But damn this is pretty decent

Did the capture while it was still bright outside, probably what made the difference

[somber stratus]

Doesn't make much difference. I imaged during mid-afternoon last time around.

Sky was bright

fairly* bright

[cursive inlet]

nah mean like Venus was higher than it usually was when I imaged

Cuz I didn't wait until it was naked eye visible

[somber stratus]

Mb, misread. Yeah, can make seeing better, depending on whether you've dealt with direct heating from the Sun/tube currents

[cursive inlet]

Yeah I did the recording like 30 sec after sunset. Might try on a partly cloudy day next time, capturing when the sun is blocked by clouds but Venus isn't.

[cursive inlet]

IR not too shabby either

[somber stratus]

nice

[somber stratus]

Yeah makes a big difference

[cursive inlet]

pretty nice

@somber stratus can you give this data try?

[somber stratus]

sure

[cursive inlet]

Cooked it a bit more, dunno, looks pretty good to me

no luminance shenanigans this time

[sharp ridge]

rlly nice

[hasty hull]

Sick shot

[cursive inlet]

nice

I feel the uv data is little extrapolated tho

[ruby tartan]

I'm new to processing IR+UV on Venus

[cursive inlet]

same tbh

[somber stratus]

Something like this ig

quick job

[cursive inlet]

amazing

[somber stratus]

UV

Tried to match my colouring but you do you. It's false colour so there is no "correct" way to colour balance it.

[cursive inlet]

Looks very good

I always seem to get too much blue when I process

[somber stratus]

Normalize the tiffs in PIPP prior to sharpening. Typically gets very close to the image(s) above

Normally needs +5 temp though

[ruby tartan]

Me too

[somber stratus]

But doesnt look as blue as Lucca's after initial combination

[cursive inlet]

Normalize before sharpening?

[somber stratus]

Correct

After stacking, before sharpening

If you sharpen, you bring the white point up unpredictably due to wavelets.

So normalisation is only meaningful prior to sharpening.

[cursive inlet]

aight

[somber stratus]

This can also work relatively well i've noticed

Here applied to Lucca's above

Image>Adjustments>Levels

(if you have PS of course)

[ruby tartan]

I liked this option, does it work for other planets or just Venus?

[cursive inlet]

gonna pirate it rn...

[somber stratus]

Jupiter occasionally

[sharp ridge]

Terminator* look kinda weird

[somber stratus]

I've had it work perfectly on some data, but quite poorly on other sets so, idk

[ruby tartan]

Blame the UV being flatter than the IR, I had to remove the terminator if it wouldn't be just one color

[somber stratus]

Is it not supposed to slowly fade due to limb darkening, like in my process?

Think Ken is talking about the abrupt change from light to dark.

maybe

[sharp ridge]

Yeah

[cursive inlet]

Looks too clean

[ruby tartan]

oh my mistake

Better?

[cursive inlet]

Yeah data is pretty poor

[cursive inlet]

yeah

[somber stratus]

Yup, looking good

[cursive inlet]

@somber stratus what % do you normalize to?

[somber stratus]

50 usually

But 30-70 will do.

[cursive inlet]

like this?

[somber stratus]

ye

[somber stratus]

Managed to implement my Mars map into WJ ephemerides.

[cursive inlet]

@somber stratus aight thanks, finally got the colors right

Gotta say I still somewhat prefer your version

idk tho my first attempt is fuller and probably more acurate considering the lesser amount of sharpening

[livid sierra]

Good soup

[hasty hull]

[ruby tartan]

Nice, in 10 days I will also try to capture saturn

[somber stratus]

powerful

Will have to wait until late June for it to breach 20deg altitude here

[sharp ridge]

whats the max alt this apparition for you

[ruby tartan]

That's sad, here it's already reaching 20° a little after sunrise

Saturn 20° at 5:30am

[sharp ridge]

12deg at 6 for me

[somber stratus]

27

[sharp ridge]

not bad

[somber stratus]

Pretty shite but better than the 23° of last year.

[sharp ridge]

Lol for me gained a whole 3 degrees in alt to 55

[somber stratus]

Only benefit of my latitude is that when 2031 eventually arrives, it'll be up for 16.5 hours. Could go for an ultra long timelapse of the moons.

[sharp ridge]

Jupiter would be a great apparition this year tho, 49.4" + +13dec ecliptic + autumn seeing

[somber stratus]

Yeah, october/nov aint the best though

September is optimal, i.e last year

Then again the gain in altitude probably cancels it out.

[sharp ridge]

so yeah

[somber stratus]

what is this from?

[sharp ridge]

d peach patreon

idk why i joined lmfao

[somber stratus]

Ah yeah i've never joined it

not really needed for experienced imagers like yourself ngl

[ruby tartan]

27 degrees maximum altitude?

[somber stratus]

Yes, was 23 last year. I'm at 51.3°N

Hence the spam of IR-RGB images

[ruby tartan]

Now that's sad, here it doesn't go down from 50°

[somber stratus]

Oh yeah, 27 is by no means "bad" here too. Lowest was 15° in 2018-19. Jupiter was similar over the same period too.

Mars got to a maximum of 10° in 2018.

Will be 8° in 2031 (or 33?), not sure

[ruby tartan]

Here the maximum altitude for Saturn will be 88°

[somber stratus]

juicy

[hasty hull]

I think it’s like 38 here

[ruby tartan]

It's so nice to live near the equator (-10°)

[somber stratus]

Anything above 35 is certainly workable

Sub-30 is where good seeing can only do so much

Never gunna reach diffraction limit with a large scope

[ruby tartan]

Jupiter will be 65°~

[sharp ridge]

82 or smth in HK

[somber stratus]

Quite similar to me this year actually. 53°

[somber stratus]

This was excellent seeing (or rather "moments" of). 19° altitude in OSC, no IR. Fairly sure this close to the limit of what's possible at such low altitude. The disc is usually quite low contrast with regards to banding, but only so much you can do

[sharp ridge]

Hope to get Ganymede again - still 1.8" + 16" dob should have better results eh
also potential for dual scope imaging / utilization

[sharp ridge]

tbh looks more natural

[somber stratus]

what lower contrast disc?

true

Always nice to get encke though

Found it's quite doable even under average to poor seeing

you just need aperture

[livid sierra]

@somber stratus how does Saturn get higher there than here lol

Only gets up to 25° here

Oh wait damn lmao

What I’m located higher than you

That’s crazy

Never realised that

[somber stratus]

skill diff

[obtuse yew]

36° in the land of the free

[thick heron]

Can’t complain about 50 degrees for Saturn and 75 for Jupiter.

[fading plume]

69 degrees for me

[obtuse yew]

Netherlands? Denmark?

[craggy wasp]

Well, that gives me one more reason to buy an 8" dob

[craggy wasp]

I'll need to wait 4 months

[sharp ridge]

hey so quick question im not sure what camera to buy for a heritage 150p, i’ve seen a 224mc, a mars-c, mars c II, and a neptune c II which one would be better for me or are there any other suggestions you have? thanks!

[hasty hull]

Mars trolling tonight. 6.6” across

[hasty hull]

Out of those, I’d say Neptune-c ii

It has a nice pretty wide sensor

Those are all solid cameras though

[somber stratus]

Agree with willaf

[clear pier]

hmm ok it’s at the same price as the mars c ii rn so i was wondering if it’s the best for that price range

is there anything else better in that price range or is the neptune just great?

also also will this work for dsos?

[hasty hull]

Yes, it’ll just take a decent amount of patience because your subs will have to be super short

[clear pier]

ok cool so get the neptune?

(also what are subs and what’s the disadvantage of them being short?)

[hasty hull]

Subs are the frames/images you capture

The longer the subs, the more signal and less noise show up

But you can compensate for short subs by taking a huge amount of them

[clear pier]

ahh ok makes sense

[fading plume]

Planetary chat dead frfr

[livid sierra]

No planets

Give it some time homie

They’re shy

[livid sierra]

@cursive inlet I think I'm gonna order the w47 filter and just use it with the ZWO uvir cut even though that one only passes from 400nm onwards

https://www.planetary-astronomy-and-imaging.com/en/best-filters-for-venus/ But what I'm making from this article and this image is that Venus' spectrum is strongest after 400nm anyway

And here Pellier states that indeed it doesn't matter much if the uvir cut utilised isn't completely transparent to uv

So yeah I think I'll just buy only the w47 for now, don't feel like buying a whole IR blocking filter for €59 (I can't find a cheaper one that passes UV and the Astronomik costs €59 on their own website too). I'm still thinking of buying a mono camera later down the line so with that in mind I'll just go with this for now

[cursive inlet]

Yeah that will work

[cursive inlet]

Only planet worth shooting now is Venus

Plus clouds for the past 2 weeks at least for me

[livid sierra]

Same

[somber stratus]

EU has been clouded hard the last few weeks

[livid sierra]

Looks like it might be clear for me this Sunday

According to Windy

With some pretty okay conditions

[somber stratus]

Noticed too. Jet stream never too far away though

[livid sierra]

True

But better than nuffin

[ruby tartan]

My EQ5 is working again, this week I should capture Saturn and Venus

[fading plume]

nice. I was looking when i should image saturn. june it reaches peak alt before sunrise

also, earning some nice money atm. i should get a nice barlow. x-cel 3x maybe.

[somber stratus]

Apollo-M Max just arrived. Solar rig is now waiting for me tomorrow when i get back from Uni

[ruby tartan]

Collimated telescope, possible clear night tonight

[cursive inlet]

Tis was a ruse

[livid sierra]

Might actually be able to do some Venus later today

Set my telescope up outside in case these clouds really stay away a little while longer

To let it cool off

I’m prayin mayn

[cursive inlet]

Where do you image from?

[livid sierra]

[cursive inlet]

Oh cool

[livid sierra]

Looks like there might be a gap approaching according to Windy

[vagrant cliff]

how did u get manual on iphone?

[near quiver]

Fotogear app

[vagrant cliff]

is it free?
manual video aswell?

[vagrant cliff]

would you recommend samsung/google/apple phone for planetary and light deep space? any pics for refernce>

[near quiver]

No

A cheap planetary camera or dslr will be much better

[vagrant cliff]

any under £60 plantary cams?

[near quiver]

Your best bet is a used dslr or a used asi120mc mini

[vagrant cliff]

is a used dslr usable fora ny deep space untracked?

[near quiver]

Yes definitely

I use a dslr untracked for my pfp

[vagrant cliff]

WOW

[vagrant cliff]

any galaxies possible with untracked dslr? and dslr recommednations?

[near quiver]

Canon T3i if you can find one. And yes plenty of galaxies are possible, most notably m31 and m33

T3i will be much better than what I have

[vagrant cliff]

any good plantary with t3i?

are smaller galaxies like stepehn quintent not good untracked?

[vagrant cliff]

in bortle 7 & able to spend £400 split on dslr and a new phone :/

[near quiver]

I am also in b7

[vagrant cliff]

how so good pics?!?

[near quiver]

But yeah prioritize a phone, real life is more important that this silly hobby

[near quiver]

Lots of experience and time

[vagrant cliff]

alr

t3i and then prob an older samsung

[livid sierra]

Alr just got 60k frames IR and 25k frames rgb on Venus

Guud shiet

~35deg alt though as opposed to 45deg from last time

But this time it’s dark so I’m looking forward to the results

Might actually wait a few minutes and do a 2 frame animation or sum

Correction: 25deg alt lol, misentered an option during hc setup

[topaz elk]

[ruby tartan]

Today the sky was clear, but the mount had the motorization direction reversed, I hope that tomorrow at dawn with clear skies to capture saturn

[somber stratus]

manual tracking time

I'm not even gunna attempt Saturn until late June

[ruby tartan]

I've done manual tracking for a long time, now I'm lazy, I think everyone gets like that

[ruby tartan]

What do you think of this image of titan, oops, venus

[hasty hull]

grabbed Ina just now

[somber stratus]

Strange looking for sure

Would have to see each of the raw channels though

[ruby tartan]

I just captured Saturn, when I went to see the files here on the computer, all with 1000 frames

😭

[livid sierra]

You took a bunch of 1000 frames captures?

[ruby tartan]

Yes

Instead of being 6000 frame videos, they were 1000 frames

[livid sierra]

Oh you can just combine em can’t you?

[ruby tartan]

I already do this with WinJupos, but on a larger scale and with more frames

[livid sierra]

So to put it like this you captured 3000 frames instead of 18000

In total

[ruby tartan]

I captured 8 videos (For Saturn, I usually capture 30 videos) of 60s, each one always gets 6000 frames, but this time I must have forgotten to configure firecapture and it saved 1000 instead of 6000

I'll check right now

[livid sierra]

Pain

[ruby tartan]

I checked and everything is normal, 100fps, it must have been an error that I didn't realize at the time of capture

Whatever, the focus didn't seem to be very good

[livid sierra]

Sad

And you didn’t have it limited to 1000fps per capture either?

[ruby tartan]

Maybe

Or I accidentally limited the fps to 17

[somber stratus]

oof

lesson learnt i guess

[near quiver]

two images my friend took last night. it was my gear and i tracked and processed but she gets the credit because she pressed the start and stop buttons.

[cursive inlet]

Cassini lookin good

[ruby tartan]

Nice

[near quiver]

Thank you

[ruby tartan]

Difficult file to process, low frame and a lot of noise

[somber stratus]

Why is the globe seemingly sharper than the rings?

[ruby tartan]

Separate processing, it doesn't usually look like this, but since the focus was off, I didn't process the rings

[steep apex]

I don’t know why but I really like this Saturn

[somber stratus]

Ah so you masked the rings from a single capture or something?

Then derotated the globe.

[ruby tartan]

I de-rotate normally, when I go to photoshop to process, I make a mask for the planet and another one for the rings

[somber stratus]

Ah so you mean final processing in PS. Like extra sharpening & camera raw done separately. Gotcha

[ruby tartan]

Almost like that, I sharpen the astrosurface, de-rotate it and then throw it in photoshop, that's where I really process it

[somber stratus]

Huh interesting. I do most of it in AS, then derotate. Colour & finishing noise control in PS.

Only so much you can do in PS. Some of the processes in there infer a lot of data and aren't overly accurate imho.

unsharp mask & despeckle are good though.

[ruby tartan]

That's why I didn't even want to process this image too much, I just removed the noise and tightened up the details a little, maybe I'll try to process some good files through AS to compare

[somber stratus]

Yeah, I mean PS is good for final adjustments, but Idk about using it as a more major step. I'm mainly talking about things like smart sharpen & similar.

worth the comparison

could be interesting

[lunar hamlet]

ina is in there, nice image

can’t see it in my screen shot because discord compression

[livid sierra]

My Venus capture from yesterday IR-RGB

[flint veldt]

is the IR filter just make the cloud possible to see ?

[livid sierra]

Correct

The IR image is used as luminance

[somber stratus]

& it's sharper in most cases

[near quiver]

i want to buy an ir pass filter, what kind should i buy for my asi224mc? currently looking at 850nm but im not set on that

[livid sierra]

What aperture

[near quiver]

8"

[livid sierra]

Maybe 610nm is better

Or 685

[near quiver]

how do i know which ones are good to use?

[livid sierra]

224 doesn’t have that high sensitivity from 850 and with the reduction in resolution and 8” I don’t think that’d be a good choice personally

This is the response curve of the 224mc

[near quiver]

how do different wavelengths affect the image?

[livid sierra]

Depends on the planet

[near quiver]

i would probably mostly be using it for moon and venus

[livid sierra]

Ir generally gives better results when seeing is bad though

For the moon you’d be better of using the 610 or 685

And I think 8” aperture plus 224mc’s low sensitivity from 850nm won’t give good results

Keep in mind infrared imaging makes for a lower resolution too

[near quiver]

that makes sense, less light

[livid sierra]

Low sensitivity makes for less light yes and low resolution is caused by the big wavelength

[near quiver]

i am struggling to find a narrowband 610nm filter

[livid sierra]

I have a Baader 610

From Astroshop

[near quiver]

the longpass one

[livid sierra]

Yes

[near quiver]

ok cool thank you

[hasty hull]

Ordered one from baader in mid December, still hasn’t shipped

[livid sierra]

Cancel your order bruv

You waiting on nothing

[barren dune]

Some lunar from last night

[somber stratus]

Back in business after 6 weeks

Seeing meh, but should get better tomorrow maybe

[ruby tartan]

👌

[livid sierra]

Did you get it collimated finally?

[somber stratus]

IR850 quite interesting

[livid sierra]

Oooh

[cursive inlet]

Yeahh buddy

Good week ahead

Might have a chance to bag Mercury for the first time

[livid sierra]

@cursive inlet Could you show me an image with your w47+ir block filter?

Not an RGB combined one, just the w47+ir block image

I used mine with the zwo uvir cut for the first time today but looks like the zwo cutting at 400nm might be too much, detail in the image resembles for ir than it does uv

[cursive inlet]

This was back in February, probably the best I've gotten yet. That being said I haven't gotten anything that decent yet since most of my sessions have been after sunset.

[cursive inlet]

With the osc most of your signal is still above 400nm which is why the ir cut doesn't make a huge difference.

@livid sierra could you send your uv image?

[livid sierra]

This is mine

And this is IR

Tom mentioned to me that in UV the poles should be brighter than the centre of the planet

[cursive inlet]

Looks good to me, nice whiter polar region in your uv, maybe need a little more wavelets

[somber stratus]

much lower contrast though

than actual UV

[livid sierra]

I did one edit combining the RGB data just to see how it would look

Gonna reprocess it tomorrow again to do better edge rind removal and stuff

[cursive inlet]

Dunno about you but that looks sweet

[somber stratus]

This was my UV from the same time Guga for reference

tbh i think the UV/IR cut is punishing you Duif

[livid sierra]

Thanks

[somber stratus]

you're basically shooting blue

[livid sierra]

Yeah that's true but do you think getting that IR block would make much of a difference?

[somber stratus]

I mean it's necessary due to the IR leak unfortunately

unless you find a new filter that only blocks IR

[livid sierra]

This is the Astronomik IR block spectrum

[somber stratus]

whatever that might be

thats decent

[livid sierra]

But it costs 60 bucks it's so stupid

[somber stratus]

very decent actually

ah

best to go onto actual UV at that point

[livid sierra]

Yeah but with osc?

Not really worth it is it

[cursive inlet]

https://teleskopy.pl/product_info.php?products_id=4088&lunety=Filtr Astronomik IR BLOCK w oprawie 1 25 8H0009 check out this polish shop

got all my stuff from here

nvm the filter is out of stock

[livid sierra]

Pain

[cursive inlet]

but still, they have a lot of cheap stuff

[livid sierra]

Also a shame I can't find any other uvir cuts or IR blocks that don't cut from 400nm

[ruby tartan]

Wait, don't you have a UV/IR block?

[somber stratus]

He does, but it's ZWO. Blocks 400nm & below

results in only blue light being transmitted

This is for W47+IR cut application on Venus

[ruby tartan]

Isn't that the purpose of an ir-uv blocker?

[somber stratus]

yes, but you can get some that cut-on a little lower down, into the UV a touch

helps get that UV detail.

I.e Astronomik L-3 filter for example

[ruby tartan]

Like this one from playerone?

[somber stratus]

yeah

This is ZWO

That extra ~20-30nm makes a massive difference

[ruby tartan]

[hasty hull]

@ruby tartan you are super good at processing Venus, heres some data i got under good seeing tonight. Play around with it if you want, im just curious on whats in here because I suck

rgb and uv

[livid sierra]

I’m considering that very much now, just import taxes and shipping will add onto it quite a bit

[ruby tartan]

I turned the RGB image into a mono image as it didn't show many colors

[livid sierra]

I ordered it lol

I swear this is the last filter I’m buying for now

[livid sierra]

No wait I wanna buy some solar foil later too

Dang it

[cursive inlet]

Buy a ch4 too 😂

[livid sierra]

Nah ch4 kinda boring

[hasty hull]

Awesome

[somber stratus]

woah

[livid sierra]

Well for the price

It’s kinda meh

[cursive inlet]

What about a c2h6 filer 😱

Do those even exist?

[livid sierra]

Actually got it to look pretty decent as opposed to what I got yesterday don't you think @somber stratus @cursive inlet

[bleak oak]

Has anyone ever used Registax for stacking? XD

[topaz elk]

bro thats like 1 m^2 for each AP

so you need more like what duif said

[bleak oak]

It were 27.000

About 703 703,7037037037 Meters Square per Ap

[stray chasm]

I have but I actually just switched to autostakker because of how much error could occur with registax

[onyx garnet]

neat images

[cursive inlet]

Might have a shot at Mercury for the first time if it stays clear till sunset.

[ruby tartan]

Good luck

[livid sierra]

I tried yesterday

Had it for a sec but then lost it

But good luck

[cursive inlet]

Its gonna pretty low though, yall recommend the 685nm or 850nm?

[livid sierra]

I’d think 850nm. You got one?

[sharp ridge]

850 if ya got the aperture

685 should be good enough

[livid sierra]

Yeah that’s what I was thinking too 850nm might be a bit much for 8”

[cursive inlet]

Did a test in December, the resolution loss isn’t THAT bad.

This was under 1/5 seeing, probably what I will be imaging through tonight since Mercury is going to be very very low.

[livid sierra]

Mercury is tiny tho

[sharp ridge]

purpose of 850 is mainly for daytime imaging of mercury to avoid poor seeing, not cope with shit low alt seeing

ofc in 1/5 850 will outperform color

[cursive inlet]

Ill do both 850 and 685 then

[cursive inlet]

Yeah

Barely even got the phase

Shits horrible

[summer field]

yeah, the resolution loss isn't that bad in poor seeing 🙂

[livid sierra]

Lol

I think Mercury might be easier during the day

Sun will be a b*tch

But what I struggled with yesterday was trying to find it and keep it before it went too low

[cursive inlet]

Got some Venus data though

[normal forge]

Anyone here doing ( don't laugh! ) analog lunar / planetary imaging? O_o

[livid sierra]

Probably not

[obtuse yew]

If I had a huge scope id love to try something like this with 35mm film

I really think you'd need 16+ inches of aperture. Ideally 20

[white prawn]

If I had the equipment, I'd try taking a few shots of the moon on film.

Planetary, however, is another world (ha!) entirely. Honestly I can't picture (ahem!) imaging planets with film. You need to stack a lot of images to get a good output, and further edit it. Sure you can buy a few rolls of film and go through them, but what happens after you develop them? Can you stack the negatives? How much can you do analog before you really need to get digital? Maybe you'll get lucky and get a few really nice single shots - heck, it's not impossible, I have a GREAT single shot of Jupiter and a couple of moons. But I can't imagine it happening often enough to actually invest in it. Not even if I had enough money to throw away at the project; if I had so much money that I wouldn't think twice about spending hundreds on film, I would probably think of other uses for those hundreds.

But the moon - something that can be imaged relatively easily in one shot with the right settings? Yeah, I could spare a few photos from a roll for that.

[normal forge]

When it comes to film rolls - i don't mind buying some.
A friend has a great Pentax K camera and i have the adapter. I used to make single shots with a Olympus EM10 II ( digital ) before getting some planetary cameras for each usecase. So iam not totally new into stressful capturing attempts.
Depending on image size, conditions etc. i would try something between 1000 f6.3 and 1500m f10.
It will be trial and error - i have to admit. But the itch to try is so strong.

[white prawn]

I definitely get what you're saying there. My viewpoint is based on at least a couple of things.
A) My best photo of Jupiter involved 5000 frames and using about 1200 of them - that's a lot of film!
B) To be perfectly honest, there's a lot involved in the analog process that I don't know - would you need to develop your own film, how do you stack them, how do you develop the stacks, how much can you work with it analog. I'm sure there's a lot that can be done analog, and it's a lot that I don't know.

BUT! That's me. Analog is something that interests me in terms of "gee, I wonder how this would work" but I'm not sure I'd be eager to go into it in-depth. 🙂

[normal forge]

I have 1 point that stands out when i had the first thoughts of doing so - i have a nice guy 1 house next to us and he is photographer and has a studio incl. a store with analog stuff. 😄

I guess i will talk to him a bit after easter holidays.

[livid sierra]

I think your only chance to get an at least somewhat successful image of a planet on film is probably gonna be either Jupiter or Saturn and you’d need perfect seeing

I don’t think stacking is possible with film Idk how that would ever work

Or you’d just use an astrocam and process your image like normal then take an analog picture of the image on the screen kek

You stack planetary images to overcome atmospheric effects to a certain degree obviously

So without perfect seeing you’d probably just get a smudge or a really vague image

[white prawn]

@livid sierra while I agree in principle with what you're saying - esp for single images - snapping a single shot of a planet that's decent can happen. Heck, I got a single image of Jupiter w/ 3 moons on a nice night. No touch-up image attached. I would be curious about how to enhance w/ analog methods.

[somber stratus]

With sufficient focal length & focus, you should get the moons every time in single exposures. They are the same surface brightness as the planet itself. Sure, Callisto is dimmer perhaps, but the other three.

Agree with what Duif said. For sufficient SNR on single analog exposures, you need longer exposure times which need excellent seeing.

[white prawn]

Two questions if you don't mind. Well maybe 3. 1) can you define "sufficient focal length"? 2) Is 1000mm sufficient? 3) Are you one of the pros that I strive to set my quality standards to? 😁

[somber stratus]

Image scale is perhaps the better word, which is tied to focal length. You need enough pixels to cover the moons (not just one!), otherwise surface brightness is irrelevant and you are indeed limited with single exposures. I would say 2000mm with any standard camera with 2-5 micron pixels.

And noone should be a standard, not a competition - strive to improve on your own images, and eventually you'll get to a very good quality.

[white prawn]

Fair enough. Thank you.

To be fair, I do strive for good quality, and I want my stuff to look like the high quality output that I see from others. So not so much competition, as much as "This looks good, I want my stuff to look good".

With perhaps a dusting of "I want to take a clearer picture of Jupiter than the one recognized as clearest from land based telescope." I'll just remove the dusting then. 😁

[somber stratus]

I see, sure.

[jaunty flame]

I’d definitely use the f6.3 scope as you’ll struggle to get a decent SNR on analog.Colour you’re limited to about 800 iso and black and white you’re looking at 3200 or possibly 6400 as a max with pushed hp5

Pushing film depends a lot on the developer (for black and white) and the actual film stock you use

Tbh I’d probably stick to blakc and white at least at the start

You can shoot a roll of pushed hp5 and dev it for much cheaper than a high iso colour stock (portra 800 is the only 800 iso stock available new atm and is about $20-25 a roll for 35mm)

[normal forge]

Thank you guys! 🙂

[normal forge]

We will go for ISO 3200.

[jaunty flame]

Delta 3200?

[ruby tartan]

Another day without capturing

[hasty hull]

Saturn this morn, 12deg altitude

[sharp ridge]

Mars rn, methane band

[somber stratus]

but why

[sharp ridge]

idk just some test

[somber stratus]

Ah yes, the CH4 rich martian atmosphere

[sharp ridge]

heard its good for venus tho

[somber stratus]

Not really

again, no methane, so it's pointless - just go IR850

Only benefit is you wouldn't need an ADC with CH4

[sharp ridge]

d peach says its pretty good

[somber stratus]

but SNR is shite

[sharp ridge]

yeah 850 is same

[somber stratus]

850 has way more signal

disagree with DP on that one

If you have no ADC, then sure.

Even then 850 passes ~150nm bandwidth, which isn't terrible even if you're using without an ADC

Plus, CH4 has less resolving power. Optical train has less transmission too. Just a lose lose.

[cursive inlet]

Bruh

[hasty hull]

Mercury at 10° altitude

[fading plume]

Leave the server.

[ruby tartan]

This was supposed to be Mars

[ruby tartan]

Venus too

[fading plume]

Now image moon in ch4

[sharp ridge]

It's just a dim ir filter

Results similar to ir850

[cursive inlet]

@somber stratus what about ch4 uranus and neptune?

Both have methane in their atmosphere

[somber stratus]

Good luck with that one

You're looking at practically 0 signal. Uranus in CH4 is unimaginably dim

[cursive inlet]

Damn aight

[somber stratus]

IR850 you need to go at native f/4-5 and even then you still need 50ms at mid-high gain

For CH4, you'd need 1 second exposures at native focal length, mid-high gain.

There's a reason Hubble CH4 images are on the order of 300 seconds each

889nm

Literally can't register it.

[cursive inlet]

https://rk.edu.pl/en/imaging-jupiter-ammonia-absorption-bands/

Could be interesting

From what I understand you subtract your ammonia image from a wider bandpass and you supposedly get an image which shows areas of lower and higher ammonia concentration

[sharp ridge]

https://britastro.org/wp-content/uploads/2022/01/EPSC-2021_Hill_Jup-in-ammonia-band.pdf

[somber stratus]

Very similar to continuum H-alpha subtraction in DSO imaging

[white prawn]

Mars is a small target, getting further away. Just this once, I liked the dithering feature on AS!3.

[ruby tartan]

Saturn this morning

[livid sierra]

Looking good

What was the altitude?

[somber stratus]

40° or so for his latitude, before sunrise

[livid sierra]

Good shit

cries in max alt of 25° all year

[lean hearth]

Planetary is cool

[cursive inlet]

Correct

[somber stratus]

I think Lucca gets zenith this year.

[somber stratus]

Join us then

[livid sierra]

Damn where he imaging from?

[somber stratus]

Brazil, 10deg South

[livid sierra]

Good location

[ruby tartan]

Correct

Almost zenith, will reach 80°

[lean hearth]

I wish I could I’ve seen ur pics they are truly amazing but I don’t think a Rokinon 135mm would make the cut or a 200mm lens (that’s the highest fl thing I own)

all I can do that’s kinda planetary ish idk if it counts is moon and sun

[hasty hull]

Pretty terrible Mercury from a bit ago

[lean hearth]

What you use?

[hasty hull]

6” dob + 3x barlow with a Mars-c + uv/ir cut filter

[craggy wasp]

Dude when will saturn be visible on chile?

[ruby tartan]

From 4 o'clock in the morning, but I think that in Chile, Saturn must be very low

[cursive inlet]

Chile is pretty long tho, probably depends where in Chile.

[somber stratus]

Most of Chile will have Saturn high up before sunrise

The planet's still at negative 12 declination

[livid sierra]

Close to perfection

[upper jewel]

@lean hearth ha! Not at those FLs !

@lean hearth you'll be lucky to get the moon 🌙

@lean hearth and no a moon or a star don't really count! Buy a cheap high FL low app refractor or a cheap high FL reflector telescope

[somber stratus]

Man got hit with the triple ping

[cursive inlet]

naw man

spacey mcspaceface 💀

[livid sierra]

Fr lmao

[cursive inlet]

@lean hearth you gotta respond with with the quadruple now

[ruby tartan]

I agree, @lean hearth you have to respond with the quadruple

[coarse aspen]

I am also in agreement, @lean hearth you have to respond with the quadruple and buy a quadruplet too.

[normal forge]

So - update from my side after my question.

I will get a Pentax K1000 ( 1976 - manufactured in Japan ) with adapter K -> T for lunar imaging.
For that my neighbour and photography shop owner said the Ilford Delta 400 would be great and pushable to ISO 800.

Seems like we are going for some first analog lunar imaging test shots in 1-2 weeks, depending on weather. O_O

If anyone is interested, i will share results here.

( That said, we do have ZWO 385MC, 178MC, 178MM and 678MC cameras to do the job - but still... we wanted to try something complete different. 🙂 )

How this happened: I have a decent Celestron C6 XLT tube that already delivered pretty good images and a friend of mine is into analog B/W photography. So this is our tiny project.

[lean hearth]

what da

[lean hearth]

I’m gonna get maybe a 12” dob soon

[upper jewel]

How do I add a photo please?

[heavy mirage]

Just drag and drop, or use the + icon to the left of messaging if you're on mobile

[cloud copper]

Did any of you guys buy anything from player one astronomy, I want to purchase a ceres-c camera and I want to know if the web site is safe

I dont want my money to be stolen

and do you know any coupons I could use?

[livid sierra]

I think everyone who uses a Player One camera here bought it straight from their website

Why would the website not be safe

[hasty hull]

PO is perfectly fine

Dozens of imagers here have had nothing but good experiences from them

[ruby tartan]

https://player-one-astronomy.com

[clear pier]

just bought a uranus c and yup perfectly safe, it just looks a little sketchy

[white prawn]

@fading plume has purchased from them before and pretty much swears by them. He has a Uranus-C

[somber stratus]

P1 are great

[cloud copper]

Ok thanks

[cloud copper]

I think the ceres c camera is the best camera that can be used for planetary in the 150$ price range, are there any other cameras that are better than it that dont pass 170$?

[somber stratus]

A second hand 462mc

[cloud copper]

I had no luck so far finding one second hand in România, searched every where :/

[livid sierra]

Mars-c?

That’s also imx462

[cloud copper]

Nice suggestion, a bit expresive I will think about it!

[white prawn]

I would give the SV105 another shot now that I know its failures might have been me rather than the camera. With that having been said, it's not a camera that's recognized natively w/ FireCapture, so I don't know how it would play w/ anything other than SharpCap. But I bought mine for about $50

[white prawn]

Sample image from that camera. Not sure anymore if I had a Barlow on it, maybe 2x? Again, not sure. And that's before I knew what I was doing for using the camera and before I learned some finer tuning of stacking itself.

[cloud copper]

I think ceres-c is way better than sv105, the 105 is cheaper but I want to buy a camera that will work for me for a long time, I cant decide between mars-c and ceres-c

sv105 only has 30 fps, ceres-c has 150 at max resolution and It can go up to 204

@white prawn

[white prawn]

Sounds fair enough, I was focusing in on price point and I completely understand that you want longevity/quality as well. SV105 may not be horrible per se, it def is a rather beginner tool and lacking in quality compared to some of the others you've mentioned.

[cloud copper]

yea, thanks for your suggestion

but why does everyone use a uranus-c camera if it only has 47fps, isnt higher fps better for planetary?

[white prawn]

I don't. I use an ASI585MC
