Planetary Imaging

[normal forge]

Even with my OSC i don't get colors on the moon. It is super faint even ramping up the sliders. Well, and introducing color noise! A LOT color noise.

[topaz elk]

do you use pipp @normal forge

[normal forge]

depends

[topaz elk]

pipp can make your videos monochrome

[normal forge]

but you have to toggle that

[cloud copper]

got this pic today with my 150/1400 newton and a p30 lite phone

looks ok

[normal forge]

mhm tomorrow ... 90-91% moon ... not the best circumstances for lunar imagine or!?

[somber stratus]

Near perfect seeing atm

[normal forge]

daaaaaaaaamn! O_O

can't wait to see the results tom!

[remote star]

looks incredibly sharp

is it stacked in registax?

[somber stratus]

no, wavelets sharpen

single 8% of 10k-frame stack

[barren dune]

Swank tom

[proper oyster]

I want to learn how to use registack more sharply since 80% of my images comne out blurry

My results are sometime like this most of the time

[remote star]

10k frames

[remote star]

you can try stacking them in autostakkert

[somber stratus]

@barren dune ik you like your Lunar

[remote star]

or even ASIStudio (asi camera not needed)

[proper oyster]

o

[remote star]

asistudio is way easier

but less control

[proper oyster]

ok

[remote star]

but also a lot faster

[proper oyster]

ah

[remote star]

and generally less artifacts

[proper oyster]

i could try that later once i got the time

[remote star]

but that's probably because I suck at using autostakkert

just process with pipp and import to asistack

[proper oyster]

ok

[remote star]

literally one button and it's done

[proper oyster]

yea icould try

[remote star]

what camera do you use?

[proper oyster]

camera phone the google pixel pro 7

[remote star]

ah

[proper oyster]

planning on a dslr soon

[remote star]

it'll work with that

just process with PIPP first

[proper oyster]

yeah i already use that

[remote star]

this is a shot with my phone

stacked in asistudio

[proper oyster]

jeez

[remote star]

same in autostakkert

[proper oyster]

yea

i can see that

[remote star]

also my main camera shoots in 3096*2080 and registax absolutely hates it

I get this

[proper oyster]

knxe the weather calm down on my side imma give a shot with my 8inch newtonian since a,l my last shot was from a 4inch one since i never had my 8inch scope

the moon pichure i did was from my 8inch scope i did yesterday

[topaz elk]

why are you shooting at that resolution

[near quiver]

Uhh use ROI you’re going to be losing a lot of framerate shooting that high res

[remote star]

What res should I use?

[near quiver]

The smallest you can fit the target in if you’re tracked, if you’re untracked just make it as small as you can and still follow it

[barren dune]

@somber stratus eat a chode

[somber stratus]

[topaz elk]

wait you manually track?

[near quiver]

Yeah why not

[topaz elk]

it makes your frames not good

[near quiver]

I just dump a higher %

[topaz elk]

just let it drift?

just let it srift with auto center

[near quiver]

Well yeah I let it drift then I correct it

[topaz elk]

ohh i thought you meant you track it continuously

[near quiver]

No that would be very silly

[topaz elk]

you have to do it for the moon tho

my firecap broke so i cant auto align with the moon

[obtuse yew]

What filters do I want to use for imaging Venus later on in the year? I have a uv/ir cut filter and a color camera right now

[near quiver]

I think people use infrared filters for Venus

[hasty hull]

Majority of the good cloud detail is in UV

[cursive inlet]

What exact camera do you have rn?

[ruby tartan]

for Venus you can use a UV filter and an IR685 filter

[cursive inlet]

UV and IR filters reveal various details in the Venusian atmosphere. UV filters show very interesting and dynamic features in the upper atmosphere where certain substances absorb uv radiation from the sun. IR filters show details usually deeper in the atmosphere, which are more mundane and less pronounced, but they are different. I assume you have a some sort of color zwo cam, in that case you shouldn’t use a uv filter as others have suggested. Those uv filters are for mono cams only, they are also very expensive. What you should use instead is a W47 violet filter in combination with an IR block. The W47 is a visual violet filter that also has a little uv in it. The problem with it is that it has a huge IR leak which can cause a double image or blurring. To combat this, on top of the w47, you also screw in an IR blocking filter, not a uv/ir cut, but an ir blocking filter. The difference between the two is that ir blocks usually let some UV light through which is beneficial in our case. This filter combination should allow you to image similar features as you would with a UV filter, maybe a little less contrast. For the IR filter, I recommend buying a 685nm pass and an 850nm pass. The 685nm pass is also useful for other planets when the seeing is bad, but the 850nm is deeper and has a higher chance of revealing details on Venus. What people usually do after collecting data is merge the different images together. Sort of how mono imagers image R, G and B separately and then combine them. With Venus, people usually substitute red for IR and B for UV, so IR(g)UV. For the green channel you can do a color capture of Venus and then extract the green channel.

Here is a list of everything you basically need: W47 violet filter, IR Block, 685nm pass, 850nm pass.

Here is an example by Damian Peach, which shows the different details from UV and IR filters, and how one can combine them into a final image.

[barren dune]

@topaz elk simply wrong

Manually tracking doesnt effect image quality that much you can easily sort the best from the worst frames in autostackert

[cloud copper]

why is it green?

[somber stratus]

Raw colour output from the camera. RGGB bayer matrix - twice the number of green pixels

[topaz elk]

yeah youre gonna get more worse franes

[cursive inlet]

I think if your fps is high enough and your manual tracking isn’t too jittery then its fine. My eq platform isn’t that good so I kind of have to slightly touch my dob to keep it in the small roi.

[topaz elk]

ive done a comparison before, its not worth it

at really high magnification you will get jitter. Plus if youre not careful and not continuously track it you will get static friction and it can mess you up if you push it too hard

[remote star]

then what's the issue with using full res and letting it drift for a minute?

apart from the large file size?

[topaz elk]

the issue with that is also high static friction which can also mess you up when you try to reframe it

plus youre not supposed to be using full res on a planetary camera

you can use the Cut-out feature to reduce file size

[remote star]

ah

[weary jungle]

Looks amazing any idea on when you will have the final image?

[somber stratus]

#older_system_pics message

[weary jungle]

Oh wow thank you I must have missed it looks awesome

[near quiver]

uh now that i bought a uv/ir filter what can i expect to change when i get it

[normal forge]

guys, how many % do you stack usually on lunar imaging with okayish captures?

[fading plume]

20 for me

[normal forge]

ok

[weary jungle]

Do you know the best percentage for Mars I found about 5% to be best

[fading plume]

it depends on your data and seeing

[normal forge]

i will show my graph... 1 second

i thought to use top 10-15% this time

am i wrong here?

[fading plume]

Yeah you could do a bit more if noise is an issue

[normal forge]

those are my graphs now...

i would go for 15% on all.

[normal forge]

Data was pretty meh.

[alpine willow]

Wide

[normal forge]

Yes!

Was the best area in that time.

Everything else was just illuminated and lacking details. :/

I prefer anything around half moon to get nice details.

[sharp ridge]

25% you want low noise

[normal forge]

thx!

[topaz elk]

graph looks kinda wonky

decrease in brightness?

[normal forge]

yeah but can't remember what is was. maybe very faint clouds.

[topaz elk]

yeah its probably why, autostakkert thinks lower in brightness means less quality

so might have good data thats low in brightness and bad data thats bright and it would say the bad data is better

kind of misleading so i usually separate the videos

[summer field]

You can try to use the "variable transparency recovery" in AS!3

[topaz elk]

yeah, usually the graph is a smooth curve, no dips like yours

kinda like this

[cursive inlet]

@topaz elk what exposure to you capture mars at?

[topaz elk]

usually around 10ms, adjust gain to get it to around 50-70%

[livid sierra]

Damn

That’s wild

[thick heron]

Not a frequent comet chaser, but couldn't help myself.

[fading plume]

Looking good

[near quiver]

I have very good seeing right now

Unfortunately I still don’t have the uv/ir cut filter

Ok I got some nice data on Jupiter and mars before clouds came in

[near quiver]

[topaz elk]

that graph doesn't look right lol

i don't think its accurate

see how the gray lines follow the green curve?

looks like your data just got worse over time or something

[near quiver]

nah i have pipp put them in quality order

it doesnt match exactly because pipp and as3 disagree on what makes a good frame

[topaz elk]

ohh

[thick heron]

Biscuit‘s spy has come to learn the secrets of using an EdgeHD 14 for planetary imaging.

[barren dune]

🤣🤣🤣

[proper oyster]

he want to use ur telescope

[thick heron]

Seemed like it.

[livid sierra]

Cute bunny

[normal forge]

Which IR band pass was it?

[cursive inlet]

685nm pass

[cloud talon]

Jupiter through my skywatcher 102 refractor and my neximage 5 camera processed through PIPP, AutoStakkert! and registax

[topaz elk]

crazy how shadows can make the terrain look

[topaz elk]

idk what im doing

[normal forge]

what camera did you use on that color shots?

[topaz elk]

a6000

with planetary cam

[remote star]

with a barlow?

got a similar one without

(same camera)

[topaz elk]

yeah

[near quiver]

I finally got it

[near quiver]

And I allegedly have clear skies tonight

[coarse aspen]

same

[topaz elk]

yeah but what kind of seeing

[topaz elk]

work in process

[floral phoenix]

I think my processing was bad

[proper oyster]

I want to take colored shot like this but i have no idea how 😅

[fading plume]

Saturate the moon heaps

[proper oyster]

Oh?

[fading plume]

Saturate and keep track of your temperature and tint.

Make sure stuff that should be whiteish is still whiteish

[proper oyster]

So like keeping the r. g. b. At a equal mount while getting most color out of it

[thick heron]

RIP CEM70. Looks like the CGEM DX is coming out of retirement.

[thick heron]

This must’ve been the work of the spy rabbits.

[lean hearth]

is the moon a planetary

[fading plume]

no, its the moon. but similar capture stuff

[lean hearth]

but would it count as me doing planetary

[fading plume]

no

[lean hearth]

I dont have a good enoigh rig to do nice planetary yet

[hasty hull]

What FL do you work at

[lean hearth]

135mm

or 200mm

i have a few lens

[hasty hull]

Yeah pretty short

You could do some long exposures of Jupiter to get the moons

[lean hearth]

Soon i will save up for a 16” dob

a nice budget rig

or maybe a 8” idk

how big is a 16” may i ask?

ive seen amazing planetary but i was told they are like bigger then some humans

[hasty hull]

Huge

Taller than most definitely

I use a 6” and get some half decent stuff

[ebon sage]

16 inches

[alpine willow]

16 inches is approximately 16 inches I think

[fading plume]

Or about 160 milliinches

[alpine willow]

No

What

milli is a thousandth

160x10^-3 is not 16

[fading plume]

1600 miliinches then

I was thinking the inch was the centimetre or something lmfao

[alpine willow]

Still wrong

16,000

[fading plume]

Oh yeah, base of 1000

Man, metric system is so hard

Anyway, 16 inches is roughly 16000 milliinches, 1600 centiinches or 160 deciinches.

[jolly leaf]

tell that to tom

[livid sierra]

Huge, I talked to Tom about it, the base does not fit through a door in one piece

It's big

[ruby tartan]

400mm, almost the same size as a newborn

[livid sierra]

Why you responding to a message from September 2022

@lean hearth oh and it’s heavy asf btw

[jolly leaf]

[topaz elk]

forgot to mask out the copyright so now its green

[lunar hamlet]

You got ina

[topaz elk]

yep lol

[lunar hamlet]

What scope?

[topaz elk]

8" dob

no barlow

1200mm*

[lunar hamlet]

Do you think I could get it with 2x Barlow, 6mm lens and a 4.5” 450mm telescope? Oh and digital zoom

[topaz elk]

whats gonna be the fl

[lunar hamlet]

The scope is f4

[topaz elk]

yeah you might be able to

not sure about the dslr setup tho

[frozen root]

https://m.youtube.com/watch?v=Fr-97irpIUg @somber stratus bro I don’t think they met you

[topaz elk]

IT HAPPENS ONLY IN INDIA!

🙄

[fading plume]

Toms seeing would like a word

He has a 120mm mak or something lmfao

My pictures are sharper by far

[barren dune]

My friend matt smith (insertastronamehere) took a 100-160 I cant remeber the exact megapixel shot of the moon its insane and trumps that kids shot by a mile

[near quiver]

I mean they’re just trying to get a quick news story, and they’re assuming nobody will actually fact check

[frozen root]

well I trust national geographic

[lean hearth]

hi

[near quiver]

Normally I do too but that just isn’t the sharpest moon image

[lean hearth]

are we excluding this image, this was captured by hubble

[fading plume]

hubble has never shot the moon though.

also LRO exists

[lean hearth]

https://hubblesite.org/contents/media/images/1999/14/796-Image.html?news=true

other hubble images

[fading plume]

huh, i thought it was limited to very long sub lengths. cool

LRO is far more detailed though.

[lean hearth]

the only guy hubble csnt image is the sun

[lean hearth]

yeah but its kinda unfair to compare something that literally orbits the moon

[fading plume]

True yeah

Still, this Indian dude capturing the most detailed moon pic is bs. I’ve gotten sharper pictures

[lean hearth]

nat geo could of done atleats a bit more research to show that he prob just told them that to make him look good

[fading plume]

At least looked at my pics

[ebon sage]

iirc hubble has tried INA

or maybe it was apollo landing sites

[ruby tartan]

he never caught mercury

[lean hearth]

forgot the one srry

[livid sierra]

Are you 16 thou

I think that’s what they’re implying

Sharpest moon pic taken by a 16 year old

I mean probably still bullshit but

[fading plume]

Ken is younger than 16 I think.

Isn’t he 15 or something lol

@sharp ridge what is your legal age

[hasty hull]

[livid sierra]

Lol

Ye I think he’s 15

[hasty hull]

I’m 15 but my lunar isn’t that great tbh

Probably will be shooting the moon a lot while planets are gone

[fading plume]

Continue DSO imaging

Istg that bot

[hasty hull]

I tried to find Owl Nebula earlier but it was invisible cus of moonlight

[livid sierra]

Oh gosh darn you can’t cuss in this server? Lol

[fading plume]

I want to try HVN tonight

[hasty hull]

It’s pretty neat, go for it

[sharp ridge]

Im 15 rn

[fading plume]

Yeah damn it’s damn 1984

[livid sierra]

Gotdamn mayn

Anyway I wish I didn’t have this FREAKIN gosh darn internship everyday I’d have so much more time and energy to be shooting shii

[fading plume]

You officially have beaten some Indian kid wanting to be famous. Congratshulations

[livid sierra]

Lol

[sharp ridge]

[livid sierra]

Come on Ken cheer up

[sharp ridge]

[sharp ridge]

what indian kid

link?

[hasty hull]

Also @fading plume I got De Mairan’s but it just ended up looking like your live view

[fading plume]

The “sharpest image ever taken of the moon by a 16 year old on national geographic

[fading plume]

Gotta grind for that 8” and Uranus c

[hasty hull]

True

I’m getting a job this summer so I’m gonna try and acquire a 12”

[sharp ridge]

lol saw it, his shot aint even special

its just that he moasiced it ig

for me i cba

[fading plume]

Can someone stack this please?

[alpine willow]

💀

[fading plume]

Man Venus is twinkling ☠️☠️☠️

[lean hearth]

wag is that

[fading plume]

New planet discovery. Blob

[livid sierra]

Yooo

FREAKIN epic

[fading plume]

What does it look like

[ebon sage]

Aliens for sure

Definitely not focus

[remote star]

anyone tried using the ASICap app on android?

[lean hearth]

blob

[turbid plume]

nice shot

[somber stratus]

Cursed Southern Hemisphere

[lean hearth]

hi

[ruby tartan]

Lol

I was his age when I got an iotd on astrobin with a toya 114mm and a good photo of the moon

That was in 2021, how time flies

[thick heron]

Update on my CEM70: Tried to re-flash its firmware multiple times shortly after the picture to no avail. Took it inside the next day and revived it with another firmware flash on the first attempt.

[gray orchid]

$50 USD SVBONY sv105 (really just a webcam off a 5 yr old laptop) paired with the mighty Orion XT8.

Sharpcap, pipp, autostakkert, Photoshop.

Using sharpcap with this CMOS camera limits the framrate to 30fps and that's if it doesn't start dropping frames, which it then drops to 15fps.

Moon image is a mosaic using a Nikon d7200 in video mode also using the XT8

[fading plume]

SV105 is a nice camera. I started with the same camera different manufacture

[burnt latch]

Took this with my dob and a phone camera

[alpine willow]

What

Sv105 is like worse than a 120mm mini

[fading plume]

just uk prices making it bad

[alpine willow]

And we all know how shit the 120mm mini is

Cheap doesn’t mean good

[fading plume]

the 120mm is 4x the price

its IMX290, its alright

for $50 its nice

[alpine willow]

Its imx290 but its svbony

They somehow destroy their sensors

[azure zealot]

I don’t even know why that pisses me off so much. Maybe cause I’ve taken pics like that before but no one bats an eye

It’s a great pic for sure

But like

We have hundreds of people that do the same thing

[thick heron]

He has a dome, which is more than I can say.

Or maybe it’s his club’s dome.

[summer field]

I finally have enough data for a map 🙂

[ruby tartan]

Nice

[somber stratus]

Got some potentially good seeing forecast with light winds throughout the atmosphere - unusually low pressure for this to happen though (990mb). Will be interesting to see how it actually turns out.

[bleak oak]

406mm is the only right answer

[gray orchid]

That's awesome.

[summer field]

thanks 🙂

[somber stratus]

Potential detection of the Epsilon ring of Uranus.

Cordelia selected. It's a shepherd moon of the Epsilon ring so the orbit shown here will closely match the ring

[near quiver]

you crazy mfer

[somber stratus]

This is a single 200-sec capture btw

Going for 2 hours tomorrow when seeing & transparency is supposedly better

[near quiver]

that would be cool

waiting for the recordsetting hdr

[somber stratus]

Not even, Ariel is visible in the linear data

[obtuse yew]

Can I use my normal planetary setup to capture this comet? Can you get a decent result using lucky imaging and stacking?

[near quiver]

I would assume so

[somber stratus]

https://media.discordapp.net/attachments/570687129118703637/1064700481760415797/2023-01-16-2020_4-TW-RG610-Uranus1_pipp.gif

inverted images - shows the diffraction spike offset due to the bright(er) northern polar hood

"Rings" also looking slightly more promising in this GIF. This is only 200s of data. I plan to get 2 hours or so tomorrow

50/50 stack

[wary siren]

where are the rings supposed to be?

[somber stratus]

just out from the planet, very close to the glare, but hints are visible

[wary siren]

OH

I see it

[thick heron]

I don’t know… seen a few claims of ring detections from scopes as small as 14”, but none looked as defined as that even with much more data. They generally look like fuzzy regions.

https://britastro.org/journal_contents_ite/amateur-detection-of-uranus-rings

(Honestly, I find all previous sub-20” detections questionable to various degrees)

With the IMX462M and SC2210 sensors, it may be more doable though.

Curious to see how the 2 hour stack will turn out!

[somber stratus]

This was 16" at native 1800mm f/4.4, drizzled 3x. IR850 filter & 462MM (early-bird)

IR850 is what does it. The contrast is much enhanced

as you're taking advantage of the CH4 absorption band

[somber stratus]

D Peach's isn't at the right scale, the moons don't match

So i agree with you there.

https://twitter.com/skyinspector/status/1492138116538273793 this is legitimate i think. I spoke to Martin about how he did it. Settings, filters, camera etc

Martin Lewis (@SkyInspector)

After several years of attempts, possibly I've finally imaged the brightest of the v.faint rings around planet Uranus!
13th Jan with 444mm scope in v.good seeing & transparency. Accumulated exp. time =112mins (80% of 140mins). Winjup derotation. Reference from Uranus Viewer 3.0

His was IR685 & 290MM, but now with the IR sens of the 462M & SC2210, it's possible to extinct the planet further with an IR850

Measured the minor & major axis of the "rings" (in my possible detection) as 55px & 65px. Arcsin(55/65) gives an inclination angle of 57.7 deg. The central point of Uranus has a latitude of 56 from stellarium. Promising but not conclusive

But yeah, need more data at the end of the day to claim anything myself. We'll see what tomorrow brings

[coarse aspen]

can you find the rings with long exposures? if you arent concerned about rotation or anything, you should be able to do single exposures?

although i dont know too much about planetary, im a deep sky guy

[somber stratus]

Tracking is never that accurate, unless you had a top notch mount. Also you want to lucky image to retain image sharpness.

But in theory, with perfect seeing and a good mount, yes.

[coarse aspen]

i forgot about the part where you'll need a large telescope and high focal length

so yeah tracking isnt easy

[somber stratus]

Yup haha, maximum diameter of the rings is about 8-arcsec

without considering how thin they are

[coarse aspen]

dont you shoot at 7000mm with your dob?

[somber stratus]

yeah, 8750 for normal planetary

[coarse aspen]

wow even higher

[somber stratus]

but this needs light bucket mode

1800 f/4.4

[coarse aspen]

your dob is that fast?

[somber stratus]

yeah, most are f/4-f/6

[coarse aspen]

nice

[somber stratus]

One of the benefits over SCTs

[coarse aspen]

most scts are pretty slow arent they?

[somber stratus]

f/10 or worse typically yeah

[coarse aspen]

yeah what i thought

off topic question, but have you resolved any of Jupiter's moons other than the four galilean?

[somber stratus]

nope, i would like to try to detect some of the minor ones next season

[coarse aspen]

yeah i never see anything about the other moons

[somber stratus]

would likely need a IR850 or CH4 filter at native f ratio

IR850 would extinct the planet enough to get the shepherd moons of the main Jovian ring. Forgot their names

Metis

[thick heron]

That one is by far the best I have seen yet. I have tried with the same filter & camera with my EdgeHD 14 but all I see are clean diffraction rings every time. This one is 1 hour of data from August 2020.

I think Peach’s is maybe a real detection. The simulation is scaled smaller but otherwise lines up.

[somber stratus]

Yeah, hence why i calculated the eccentricity & inclination angle - to negate this otherwise circular diffraction ringing. True i suppose.

You're kinda limited with a C14 due to the f ratio

[coarse aspen]

what would be the minimum focal length to resolve these rings?

[somber stratus]

But we'll be screwed in ~2030 when the rings are face-on and near circular 😆

[somber stratus]

Aperture is more the question to ask. I think you could get them with a 12" at f/4 possibly. Otherwise at least 14+ to even have a chance.

[thick heron]

My plan is to try again near opposition with my 685, 850, and maybe CH4 filter if my QHY5III200M is up to the task. The bigger pixels should help if I want to decrease to F/11.

[somber stratus]

You need light gathering power. Much the same as stellar magnitude limit's a scope can resolve. The rings are so dim you need a massive aperture.

[somber stratus]

CH4 is too deep i think, but maybe with enough integration. Forgot the 200M has large enough pixels for you at native f/11.

CH4 would certainly look the best and yield the highest contrast - but how many hours of pain you must endure to achieve a usable image, i don't want to know

It might eventually be needed though, as the (bright) NPR rotates into central view over the next few years. Might need to extinct the planet even more than the IR850

I’ll do a few captures of CH4 tomorrow if I find the time. See how they end up.

[thick heron]

Guess I will find out and report back later this year. The SC2210 might be up to the task at F/11 given how clean the sensor is.

[somber stratus]

Yeah. Also worthy of note, use an offset/brightness during capture - helps massively with dynamic range & general cleanliness to the image. Did a capture with and without 300 offset and it was night & day.

Much improved

[lofty grove]

Quick question for all. I just got an ASI224MC. When I hook it up to SharpCap, is see the blue and red sliders but no green slider! The image looks weird without green. What's really weird is its showing a green channel active in the histogram. I would like to take this imager out sometime and use it but not if it's giving me this kind of problem! Help!!!!

[thick heron]

There are only red and blue sliders. You can always balance in post-processing.

[somber stratus]

There are green sliders in Firecapture though. Maybe that’s only for the P1 Uranus-C though. Haven’t got the 224MC

[lofty grove]

There's green sliders in SharpCap too. Just doesn't seem to be the case for this imager! Wish I'd known that before!

[thick heron]

Just remembered I have a friend with a 30” Obsession dob. Might make detecting rings slightly easier. 🤔

[fading plume]

Why can’t my friends have 30” obsession dobs.

[thick heron]

It brings the joy of astrophotography to visual astronomy.

[near quiver]

man why does everyone want a girlfriend when you can have 30" obsession dob

[somber stratus]

that’ll do it 😆

[thick heron]

Only seen this monster out once in the 5 years I've known this friend. It is towed in its own trailer.

[thick heron]

What if the girlfriend had an Obsession 30"?

[ebon sage]

jackpot

[near quiver]

then shes a damn keeper

she has the best hobby and also a lot of money

[ebon sage]

when i make it big u get one

[fading plume]

Then you wake up

[thick heron]

I wish Obsession still made the classic scopes. They discontinued them for going all in on Ultra-compacts a couple years ago, but I hear they have issues holding collimation (not that my EdgeHD 14 is great at that either).

The current front-runner of big dobs for me is New Moon Telescopes.

[wispy pagoda]

45k for a 30 inch at f3

[thick heron]

I’d prefer something small and affordable like the 20” or 22”.

[somber stratus]

“Small”

[wispy pagoda]

Let me dream

[thick heron]

I bet it’s at least as manageable as the FlexTube 400P. Seeing a tube that big and heavy without handles makes me shudder.

I would be interested in the Orion XX16G if they still made them. Same as the FlexTube 400P but with real trusses that let the OTA come apart.

Oh wait…

“Expected Ship Date: 01/31/2023”

I’m shocked to see this after their lawsuit with Synta.

Maybe an XX16G is in the cards after all. A nice intermediate step between the EdgeHD 14 and a big dob.

[lean hearth]

bro thats amazing i can see it faintly

[somber stratus]

I have the 400P, and previously the XX12G. Keeps collimation much the same.

[livid sierra]

I think I much prefer the Flextube models over the Orion XX truss models that have to come completely apart

Personally

The Flextube is just super convenient

[somber stratus]

Skywatcher one is lighter. I also got it due to the satellite tracker that SW have in testing.

[thick heron]

I’m concerned about carrying such a large OTA as a single unit without a handle. Don’t mind the heavier version from Orion if the individual pieces are more manageable.

On a tangent, I consider this video a required watch for any amateur astronomer: https://youtu.be/TBawz69qo_A

[livid sierra]

Putting it like that, yea the flextube does get a little unmanageable to carry on your own after a certain aperture. I own the 12” personally and I have no major issues bringing it outside or inside on my own, but I’d imagine the 16” and maybe even the 14” would be a pain in the ass to handle

It does only go up to 16” tho, after that I believe SW goes for a full on truss type dob

[thick heron]

Sky-Watcher USA stopped distributing those truss dobs a couple years ago. They tend to be pickier about the products they offer compared to the European market and price them quite a bit higher too. The FlexTube 400P is almost $1300 more expensive here than in the UK.

Last I checked, FLO will belt-mod a new HEQ5 Pro and ship it here to Texas for less than buying a stock mount from a US dealer. This is after accounting for shipping and an 8% import tax.

[somber stratus]

yeah, SW stuff is insanely cheap here through FLO

my 400P was 2.8k iirc

huh, that's pretty neat. Just reading a little more on the Epsilon ring of Uranus. It has a slight elliptical nature to it. Eccentricity is 0.0079. Not much, but enough to cause spread of particles at apoapsis, increasing the width of the ring, and thus the apparent brightness. Particles spend more of their time at apoapsis too so there's a higher proportion of particles intrinsically. It has a min-max brightness ratio (associated with periapsis-apoapsis) of 2.5-3x. 3x brighter. Will be interesting to see if i can detect this tonight given good collimation & 2 hours or so of data.

One side should be noticeably brighter

Also explains this asymmetry in ring brightness from Hubble.

[livid sierra]

Interesting. Makes it seem like SW favours business in some regions over others

[sharp ridge]

damn i looked at it and apparently they ship to Hong Kong yay
like 27000 hkd instead of 36000 I expected to pay via opt or smth

might be able to pick one up much quicker than expected

[somber stratus]

With planets near zenith that alt-az is gunna go funky

Ig only for very favourable oppositions at max declination

[barren dune]

lmao yes it has

[fading plume]

yeah i saw

[barren dune]

those are rings my man at least one but confirm with better data

im looking at a 24in hubble optics dob with goto only about 13k

[somber stratus]

Yeah, plan to get a good 40x the data tonight

2 hours if seeing/cloud holds

[livid sierra]

Gahdd damn mayn

Only bout 13k huh

Buy me one plox

[thick heron]

I’ve heard mixed things about Hubble Optics, but it’s probably the best option if the others are unobtainable.

[thick heron]

FLO ships to Hong Kong, but they won’t ship THAT to Hong Kong (or the US 😠).

Looks like they’ll only ship the 400P within the UK. Not even France and Ireland. Maybe another European dealer will though.

[topaz elk]

ina kinda blue

[topaz elk]

uranus update ‼️

[somber stratus]

@thick heron What do you think? Seeing was terrible for most of tonight, only a handful out of 40x 3m captures were usable. This is 5 stacks (12m int.) - a couple from yesterday, a couple from today, hence the moons are all over the place & duplicated.

Promising, but not conclusive enough. Need better seeing

[thick heron]

I think it looks promising! Would be curious to see a processing of just tonight's data since we already know a ring-like structure is visible in last night's image.

[somber stratus]

Sure, here is just tonight's data - hints but pretty questionable. Certainly on the edge of detectability with the seeing i had. Planetary glare was enhanced quite a bit as you can see.

This was 3 x 180s, 60%

[thick heron]

Still looks good. 👍

[thick heron]

Not sure if anyone here using WinJUPOS has tried the "create settings files (*.ims) for an image stack" feature, but it never worked for me until the most recent release.
Now that it works, saving WinJUPOS measurements for a dozen images will be less tedious.

[livid sierra]

How so?

[thick heron]

After lining up the wireframe to one image, it turns 3 mouse clicks per image (Open Image -> Save -> Save) into one click for all at once so long as their scale and rotation are the same.
It never worked for me until I sent a bug report the most recent update addressed.

[livid sierra]

I see sooo, I could input 10 Mars images, line up the outline correctly for one and it’ll automatically save that one as well as the other 9 at once? Would that work for alt-az mounts too tho?

[thick heron]

No for alt-az right now, but I sent a feature request for that almost half an hour ago.

(out of the goodness of my heart and totally not because I may be an Alt-Az user in the future)

[livid sierra]

Awesome! Hope they work it through

[thick heron]

In theory it is a simple addition. Just need time and location, both of which are already there.

[livid sierra]

Can’t wait to see the option in it. Will save so much finicking with them buttons like you said, opening an image and saving it and repeating that like a thousand times

[summer field]

I never tried it but this feature will save me so much time with a few hundreds of images to process for jupiter maps 😄

[remote star]

very quick shot with my manual dob and 178MC

atmosphere was causing a lot of distortion and seeing wasn't great

[coarse aspen]

That is a really promising image

[remote star]

It is a lot better than the one I did before

But with no barlow I've had better results so far (due to seeing, hopefully it improves soon)

[coarse aspen]

I'm gonna process this PNG for ya

@remote star Changed the color balance and did deconvolution

Bit noisy though

It brought out more details at least

Heres a version with better colors id say

[remote star]

thx

looks much better

[thick heron]

@somber stratus Curious to know how responsive the FlexTube base is to directional inputs. Hoping it would be nearly as responsive as my CEM70 (basically instantaneous), but worried it could be more like my CGEM DX (holding the direction button for at least 10 seconds working through dec backlash).

[somber stratus]

Mine has 0 backlash, continues to work flawlessly (touch wood). Had it for a year now, about 50 sessions

Tracking accuracy is meh, as is the case with alt-az. But motors work fine

[thick heron]

All good news as long as it can keep a planet on-chip.

[somber stratus]

@thick heron Managed to drop the glare a touch more. Quite convincing I think. Before & after. Nuked the first image with some large(r) scale wavelets to increase contrast, spin-blurred it a touch to drop the noise a little, then multiplied with the original at 25%.

gunna do a few more tests with this, see if it's fool proof and actually doing what i want

ring detail/noise looks near identical in both though, which is promising

Exclusion layer looks ok bar the lower left. I want it to look like there's no ring at all - only removing the somewhat-gaussian glare

[thick heron]

What you should do is get a GSO 12” newt and do some “geometric transformations” to really pull out those rings. I hear you can go beyond the diffraction limit that way.

[somber stratus]

lmao

i posted this as a joke on r/ap already

the ring system is quite a bit more extensive

should call for a discovery

[thick heron]

Now I’m sold on the 400P. I bet the XX16G could never do that!

[somber stratus]

lol

i am curious what my mirror's strehl ratio is

It does seem to do particularly well on Galilean Moons

this was the best of the summer. My only night with moments of (actual) perfect seeing

i might just be lucky as these things are factory made

[thick heron]

I think aperture is everything for the moons. Recently saw a Jupiter image from a big dob in meh seeing, but Ganymede looked better than I’ve ever seen from my scope in excellent seeing.

[somber stratus]

This is very true

i have a friend in Hong Kong with a C11. He frequently gets perfect seeing and can't match my images (of the moons) under 4-6/10 seeing

Ganymede in particular

But the planet itself is very similar

[coarse aspen]

those jupiter details are insane

[vast berry]

Guys how do I remove frames with only a part of a planet

there are a couple times when jupiter wandered off my roi

pipp removes most but still leaves a couple

and as3 ranks these partial frames really high and makes the stacked image weird

[coarse aspen]

Change pipp's threshold

Make it more picky

object detection, make it lower i believe

[vast berry]

that worked, thx

[wispy pagoda]

There's also a setting in autostakkert called "detect abrupt edges" or something like that

[barren dune]

glad u check for realness in rings unlike some imagers 😉

[barren dune]

i get some decent ish ganymede shots and im not collimated and my mirrors are filthy I wonder how good itll be once I fix my scope

[livid sierra]

@barren dune mind letting me try processing your data sometime?

[barren dune]

i dont have my raw data its a sin but i delete them all to make space for more

but if i get some good lunar data soon ill send it here

[somber stratus]

At least keep the raw stacks (tiffs) bruh

[barren dune]

never

im getting a 16gb ram 1tb storage laptop soon

beast for planetary and lnar

[somber stratus]

Takes up a couple hundred MB at most, a few seconds of raw video = the raw stacks from a session

it's nothing

[barren dune]

true

[somber stratus]

1tb SSD?

[barren dune]

yea

only 1.3k usd

[somber stratus]

I find USB bandwidth is the primary issue honestly. The actual ports.

[barren dune]

usb 3 ports

3 of em

[somber stratus]

The Uranus-C is absurd with data rate. Max res can output 0.4GB/s

400MB/s

[barren dune]

my god

[somber stratus]

laptop dies after about 10s

[barren dune]

i need to buy a uranus c after i fix my scope dude

lmfao

is it the wire it comes with or is it just the cam in gen

[ruby tartan]

@somber stratus I just saw it here, you really managed to register the rings of Uranus, congratulations

[livid sierra]

@barren dune boy you don’t even keep the stacks? Lol

I always keep those mayn

Can reprocess them again later with better skills yk

[somber stratus]

Thanks. I do plan to integrate way more data when seeing is next good. These two recent nights only had about 10mins of usable seeing. Planetary glare is enhanced & blows out the rings if seeing is poor.

[coarse aspen]

Planetary data takes a lot of space

[somber stratus]

raw data does

[coarse aspen]

At least keeping stacks shouldn't take up much though

[remote star]

I get about 8gb/minute

[somber stratus]

yeah that's what i was saying to Atreus

[remote star]

Not great for my 256gb macbook

[livid sierra]

Stacks barely take up any space

Like Tom said a few MBs at most

[somber stratus]

1hr 40m timelapse from the 17th Jan. You can see there's a very brief period where the glare is small enough & Miranda becomes visible @ruby tartan

can see Uranus' retrograde motion too - star upper right

[thick heron]

I have a bad dream about accidentally deleting raw data and this is the first thing I see after waking up.
(No joke)

[coarse aspen]

nightmare*

[heavy mirage]

Whats your technique for correcting field rotation? WJ?

[thick heron]

Got a reply about auto-adjusting the wireframe for Alt-Az mounts. Looks like it’s possible but could take time to implement.

[somber stratus]

python script

works as long as you don't rotate the camera in the imaging train during a session

[livid sierra]

I’m praying they take the time for it. Would be very inclusive for all planetary photographers everywhere for one and it would just be a great feature in general

[somber stratus]

@heavy mirage same thing i use for Mars stuff

[barren dune]

@thick heron lmao so sorry

[thick heron]

I hit delete on my computer and the hard drive disappeared right before my eyes.
Dreams are something.

[somber stratus]

I did actually delete some good data once by accident

usually i transfer to a HDD then delete off my imaging laptop's drive

forgot to transfer this time around

raw data for this

[thick heron]

Could’ve been the one night you caught a Jovian impact.

[somber stratus]

Not like I’d run them through impact detector anyway. Need to wait for AS!4

Think it’s integrated into the program

[thick heron]

Any day now...

I’ve never been so impatient for a checkbox.

Give

me

the

checkbox

PLEASE!

[topaz elk]

later this millenia

[silent star]

Jupiter spinning

[lunar hamlet]

Does any one know how to fix this?

[cursive inlet]

Bruh after 31 days of clouds theres some clear sky

[hasty hull]

Shoot the comet

[silent star]

What are you using?

[lunar hamlet]

iPhone 7, phone holder, nightcap camera app, 114mm aperture, 450mm long

[silent star]

Prolly use a more powerful eyepiece?

[lunar hamlet]

6mm and I think Barlow with digital zoom?

[silent star]

Ye

But I use a 4mm

[near quiver]

☄️🔫

[nova delta]

it almost doesn’t get above horizon for me so…

[hasty hull]

Comet:

[cursive inlet]

I'm literally fuming I got all my shit out and it got cloudy again

[proper oyster]

same

[cursive inlet]

I’m so exited for the comet! 😊😊😊😊

[wispy pagoda]

[cursive inlet]

Bruh what the app glitched out somehow

[limpid reef]

I haven't seen the sky in months I swear to you

i am about to go mental

i dont even care at this point about the night sky

I just want to see clear skies

I need to see blue not grey

[livid sierra]

Take vitamin D supplements

[remote star]

Some shots with 8" manual dob

I still think they could be better

[hasty hull]

Really solid, nice job

[remote star]

I mean

there are people in this same server who can achieve way better results with the same setup

but thanks anyway

I'm still starting out so I have a lot to learn

[limpid reef]

did you sharpen?

[remote star]

yeah I sharpened as much as I could until I started getting noise

[remote star]

Would derotarion make a huge difference? Or should I just wait until I have really good seeing?

Today it was about 1.2 arcseconds so pretty average

[wispy pagoda]

Derotarion enables you to stack more data so you can have less noise and sharpen more

[wispy pagoda]

Really nice! I think you can get better results but it's already a good result

[barren dune]

no

[cursive inlet]

You do derotation when the seeing is stable/doesnt change quickly. If the seeing is very variable and 3 out of like 6 stacks are sub par you actually get a worse result.

[heavy mirage]

Ordered while on sale

[livid sierra]

Epic

I ordered mine yesterday too

[somber stratus]

[livid sierra]

I was considering getting the ACS too but in the end I thought nah

[onyx garnet]

Will be ordering the same soon

prob yeah

[bitter bough]

Aw man I must have missed that. Where was it on sale? How much did you get it for?

[livid sierra]

What sale are you talking about

[heavy mirage]

I don't know what sale, but I got it for 450usd from the player one astronomy website along with acs

[bitter bough]

Ok, thanks!

[limpid reef]

some really dusty data you got here @ebon sage

[ebon sage]

I have 93 mins which I’ll be easier to edit if u want

[scarlet field]

Microbes omg

[ruby tartan]

@thick heron I opened youtube and it recommended this, it's been a long time

[frozen root]

51 million views

[thick heron]

That time-lapse has a whole story behind it.

The whole week preceding that triple shadow transit was nothing but rain and the sky cleared only a couple hours before the event started. Ground was so saturated with water it would squish under every step. At some point I was running outside every 10 minutes to clear dew off my EdgeHD 8 with a hair dryer.

[thick heron]

51K

[ruby tartan]

There are 51 thousand views, my youtube is in Portuguese

[frozen root]

oh

loll

[thick heron]

Had the same reaction too until I checked.

Not even my most viewed video.

[somber stratus]

You don't have to hair dryer all the time?

95% of nights i have to, even in the summer.

[thick heron]

Not with a dew shield or strap.

The ideal way to handle dew is with moving air. I plan to build a short shield with built-in fans to circulate air and remove the risk of inducing heat plumes.

[somber stratus]

Also wasn't this event caught by Hubble if I remember correctly

Ah i see, quite a good idea actually

[somber stratus]

yes it turns out

[thick heron]

Should be easy to do with a truss tube dob. Attach one pointed at the secondary and a few more at the primary. Just make sure they don’t add vibrations.

[somber stratus]

yeah will be tricky to completely eliminate vibrations

[thick heron]

I think multiple smaller fans is the key. I have 40x10mm MagLev fans and plan to install three for my EdgeHD 14 shield.

[ruby tartan]

I think I have these files

[somber stratus]

send

[ruby tartan]

What is the day of this, I have a lot of hubble files

[somber stratus]

23rd Jan 2015

24th maybe too, depends on timestamp timezone

[somber stratus]

G filter?

[ruby tartan]

Here are the files for that day

[lean hearth]

wish i could take sick planetary images like this

i can only take nebula images and small galaxy pics

[thick heron]

Rejoice my alt-az friends! Field rotation compensation in WinJUPOS has arrived under the Opt tab of the image measurement window.

[livid sierra]

Daaaamn that was fast af!

Epic, gonna try that out in a min

[livid sierra]

Works great! 👍

[somber stratus]

Rotates the frames automatically when loading images for .ims generation?

[thick heron]

Yes.

[cursive inlet]

Do I need to refocus when switching from visible to IR with a reflector?

[ruby tartan]

Switched manually? If so, it's good to check the focus

[cursive inlet]

Yeah I figure its good to refocus either way

[cursive inlet]

Mars in UV cuz why not

Some cloud revealed in the south

[ruby tartan]

Should I wake up at 4 am to capture Mercury?

[cursive inlet]

Idk the elongation passed already, and Mercury is gonna be very good in April

[ruby tartan]

he is still big

6,5" arcsec

[cursive inlet]

Hmm then maybe go for it, I am very interested in what kind of results you will get

[ruby tartan]

I woke up but it was cloudy, maybe tonight it will be clear

[devout spear]

Hello there

[ruby tartan]

Oi

Press F, my motors controller box stopped working, instead of buying a mono camera I will have to buy a new controller box

And it will still take at least 1 month to manufacture a new one

[lunar hamlet]

That’s “hi” in binary, i wanted to learn it at some point lol

[ebon sage]

It was self explanatory

[heavy mirage]

Let's go!

[frozen root]

[sharp ridge]

welcome to the club!

[heavy mirage]

Thanks!

[somber stratus]

based

[fading plume]

Now image planetary nebula

[cloud copper]

Guys should I buy a ceres c by player one?

[wispy pagoda]

Depends for what use

[cloud copper]

For planetary and lunar

[onyx garnet]

i would get a uranus c instead

for planetary

[nova delta]

It is almost three times more expensive

[onyx garnet]

hm

Mars C II?

[wispy pagoda]

Yep but better

What's your focal lenght?

And f ratio

Also are you tracked?

[nova delta]

Yeah I just don’t know if he can afford it since he was looking towards a way cheaper camera

[cloud copper]

Wayy to expensive

Even if I had the money my mum wont let me XD

Im looking for something in the price range of 150 usd

@wispy pagoda

My focal lenght is 1400

[wispy pagoda]

And what's your aperture?

[cloud copper]

6"

[wispy pagoda]

Do you have any Barlow?

[somber stratus]

@ruby tartan ayo

[wispy pagoda]

Lmao

What did you do

[cloud copper]

I will buy a 2X barlow, now I have one but its cheap

[wispy pagoda]

The ceres c will technically work but I have no experience with it and I don't know anyone that used it

[cloud copper]

it looks right, It has 154 fps with max resolution

Im untracked will that be a problem?

[cloud copper]

lol

[wispy pagoda]

Harder but not impossible

[remote star]

depends on your mount

[wispy pagoda]

I do untracked ap with 224mc (same sensor)

[remote star]

mine has a bit of friction so untracked can be a pain but even then it's not too bad

[cloud copper]

I will just make a driver for my mount at home with arduino XD

[remote star]

what scope do you have?

[cloud copper]

a 150/1400

[remote star]

dob?

[cloud copper]

newt

[sharp ridge]

what cam u use rn

[cloud copper]

a very cheap bresser ikro cam

I had a very low buget

[remote star]

hm

unless you change the mount

it could be a bit of a pain

[cloud copper]

IK

[sharp ridge]

Ceres C should be fine

[cloud copper]

nice

[sharp ridge]

what about 224mc tho

[remote star]

it's more expensive afaik

[cloud copper]

I want to upgrade my mount wsing arduino and some motors that way I will be tracked

[remote star]

but it is not a very strong mount

it's an eq2 right?

[cloud copper]

out of my buget

[cloud copper]

eq 3

[remote star]

still not that strong

[sharp ridge]

at least your not this guy

[cloud copper]

XD is that you?

[sharp ridge]

nah lol

[cloud copper]

oh ok XDD

@sharp ridge nice website

realy good images

[sharp ridge]

i should probably update it ive been quite lazy

[cloud copper]

did you code it ?

[sharp ridge]

google sites

[cloud copper]

XDD

looks good tho

[remote star]

you could save up, and get a neptune c or 178mc

[cloud copper]

I have the money for neptune c but my mom wont let me buy it

because its too expensive

even tho I have the money for it XDD

[livid sierra]

Tell your mom it’s educational

At least you’re not buying drugs or some shit

[cloud copper]

I know, told her but she doesnt understand

[near quiver]

Hell yeah, Pac-Man moon mosaic

[hasty hull]

Smol Mars tonight

[sharp ridge]

Thinking about an uv filter for Venus, what options would yall recommend, either expensive specialized UVenus or Wratten filters idm.

[cursive inlet]

I’ve seen some pretty damn good results with the wratten + ir block method

https://www.astrokraai.nl/viewimages.php?category=4

Also I’m not entirely sure about this but scts have problems imaging below 400nm because of the corrector plate.

All-reflecting otas I think are just generally better for stuff outside the visible spectrum

So you are better off with the w47+ir block

Also its a lot cheaper than the specialised filters

I bought the w47 a few months ago, can’t wait for Venus to get higher, always wanted to image it in uv.

[sharp ridge]

sooo.... this
https://www.firstlightoptics.com/visual-oberving-rgb-filter-sets/astro-essentials-125-wratten-47-violet-filter.html
and https://www.firstlightoptics.com/uv-ir-filters/astronomik-ir-blocking-filter.html this?

[cursive inlet]

Yup exactly. Some people use a BG39 instead of the ir block because it passes uv up until around 300nm but with the w47 it doesn’t really matter since most of your signal will be at around 390nm to 420nm.

I mean if you image mono you might get marginally better results but then again you have an sct so it doesn’t really matter.

[sharp ridge]

planning to get 16" one day soo lol

any bg39 link?

[cursive inlet]

16 what?

[sharp ridge]

dobby

[cursive inlet]

Oh well then you should buy a proper uv filter when you get the dob

Reflectors are better for imaging in uv

The wratten is best if you are short on money, have a cassegrain or an osc

Dunno where to get bg39 filters as its more industry related than astro

The ir block should work tho

[sharp ridge]

does the Uv work ok with color cams i cba to buy a dedicated 462mm or smth

[cursive inlet]

The special venus uv filter are mono only

Color cams are bad at uv

[sharp ridge]

ok

[cursive inlet]

The results from a w47 are usually pretty similar just maybe a little less contrast with the cloud structures.

[onyx garnet]

do I need a ir/uv cut or pass for planetary
google is giving me confusing answers

[cursive inlet]

What camera do you have?

[onyx garnet]

my phone, getting the asi585

[sharp ridge]

get ir-uv cut as the base and ir pass 685nm for bad seeing lum

[onyx garnet]

Okay

bad seeing refers to clouds right?

[sharp ridge]

bad seeing refers to bad seeing

[onyx garnet]

alr

[cursive inlet]

💀

[sharp ridge]

longer wavelength ir is less susceptible to seeing

[cursive inlet]

Seeing is how much the air in our atmosphere warps and distorts your view of the planet or whatever you are trying to image

[onyx garnet]

hm
alr

[cursive inlet]

@sharp ridge thanks for the follow

[onyx garnet]

so I use both at the same time for shit conditions?

[cursive inlet]

Noo

[onyx garnet]

ah ok

[sharp ridge]

lol no you switch, if you use both at the same time you get nothing

[onyx garnet]

Without any filter your camera sees everything, visible, uv and infrared. And that is bad because color balance gets messed up. Ir/uv cut allows your camera to only see what humans see, visible light. The IR pass cuts out the visible and only lets your camera see infrared.

[onyx garnet]

Alright

[cursive inlet]

And because of physics, when the atmospheric turbulence is bad, infrared light is less distorted and therefore you get a better image.

[onyx garnet]

and ppl have told me the baader neodymium filter is good, is it?

[cursive inlet]

That shits a scam

89 euro lmao

[onyx garnet]

cool

[cursive inlet]

Its for visual also btw

Actually no I take that back

Got it confused with another product

The neodymium is decent but its only for visual

[onyx garnet]

Ah f

[cursive inlet]

If thats what youre into then it might make your planetary views a bit better

[onyx garnet]

I'm looking for a 685nm filter, it's either optolong or antila

[cursive inlet]

Just get the cheaper one they are all the same

[sharp ridge]

i bought the player one one, think its pretty cheap

30 bucks

[cursive inlet]

Antlia has very good packaging tho, very fancy

[onyx garnet]

On a slightly tighter budget, antila it is

[cursive inlet]

And they look cool with that anodized metal around the filters.

[onyx garnet]

Damn

[cursive inlet]

They look very good

[onyx garnet]

Current future planetary set up:
ASI 585 MC
ASIAIR (i don't have a latop)
Antila IR PASS
Zwo ir cut
6se

[cursive inlet]

And the filter boxes close with magnets

[onyx garnet]

that's fancy

[cursive inlet]

Very

Are you on a budget? Because you can get 6” of aperture for much cheaper.

[onyx garnet]

no I alr have the scope

[cursive inlet]

Oh ok

[onyx garnet]

but I will def be looking to expand in the future

[cursive inlet]

You need a 2x barlow

[onyx garnet]

Got it

[cursive inlet]

What brand

[onyx garnet]

BST Star guider

[cursive inlet]

Ok it’s 3 element so its probably decent, doesn’t matter that much at 2x but still

Do you have an ADC

?

[onyx garnet]

nope

[cursive inlet]

Get the ZWO one

Its not mandatory but good when planets are low in the sky

[onyx garnet]

maybe not now

cos I can live with a little bit of Atmospheric Distortion and my parents don't want me to spend a lot at 1 time

[cursive inlet]

Aight that’s understandable

You should be set then

[onyx garnet]

Cool

[cursive inlet]

Wait a minute

You dont have a laptop?

[onyx garnet]

nope

[cursive inlet]

Do you have a pc of some sort?

[onyx garnet]

• my dad is like
  HoW aRe yOu gOnNa cArRy aLL tHaT stUFf dOwnStAiRS

[onyx garnet]

I gotta go downstairs to do astro

I live in a flat

[cursive inlet]

But you do have a pc for post processing right?

[onyx garnet]

Yes

[cursive inlet]

Ok that should be it then

[onyx garnet]

cool

[cursive inlet]

Are planning on doing deepsky in the future?

Im asking bcs the 585 is a weird choice for planetary

[onyx garnet]

Maybe, maybe not

[onyx garnet]

what

[sharp ridge]

fr, dads like paniking about me potentially purchasing the 400p dob, though its a valid response as its 150lbs +

[sharp ridge]

585 is king of planetary wym

[onyx garnet]

Lol

am confused

[cursive inlet]

462 ftw

[sharp ridge]

585 has better specs

[cursive inlet]

Oh wait sorry i confused it with another zwo cam starting with a 5

[sharp ridge]

533?

[onyx garnet]

What fps and resolution options does the 585 have

[sharp ridge]

wym

just roi and see

[cursive inlet]

No its not cooled but it has an apsc sensor

[onyx garnet]

Alr

[sharp ridge]

tf

[cursive inlet]

Hold on in tryin to find it

Bruh i am trippin balls

I should go to sleep @sharp ridge sorry man i had no idea wtf I was talkin abt

Thought of a camera that don exist

@sharp ridge btw if you haven’t seen this already this is how the w47 differs from the uv filters

[somber stratus]

less contrast, as expected

[sharp ridge]

tom what do you use

[cursive inlet]

Also if you don’t already have one, get a deep IR like an 850nm or smth like that so you can do those nice ir(g)uv images

[sharp ridge]

ye i just got one

[cursive inlet]

Nice

[somber stratus]

Optolong U-Venus, bandpass is 330/100

[cursive inlet]

Damn that is deep

[somber stratus]

havent properly tested yet as Venus has been very unfavourable for us northerners for the last 18 months

Should be good in the coming months though

[cursive inlet]

Yessir, Mercury is also finally gonna be imagable

[sharp ridge]

just wondering why the optolong is so much cheaper

[cursive inlet]

@somber stratus have you done Venus in IR?

[sharp ridge]

pretty sure most of his venus images are ir

[cursive inlet]

Where does he do most of his posting?

[sharp ridge]

solar system pics ofc

just search tom venus

[cursive inlet]

Nah like in general

Obv solar system pics

Im talking like social media

[sharp ridge]

insta

[somber stratus]

this was IR850, daytime, 20° alt

[cursive inlet]

Have you gotten IR detail during a fuller phase?

[somber stratus]

this only

actually

[somber stratus]

i have one from this year

[sharp ridge]

this one i think

[somber stratus]

ye

that was at 9° alt 🤏

[cursive inlet]

Lol

[sharp ridge]

do you need adc with ir filters

[somber stratus]

no

you can though

[cursive inlet]

It does look a little wobbly

[cursive inlet]

Wait what?

You dont need an adc?

[somber stratus]

IR is less affected by dispersion

but at 9 deg you need it, sure

[lean hearth]

hello

[somber stratus]

and IR850 is passing 850- ~900 or so due to camera sensitivity, quite a tight bandpass

= less dispersion

You certainly don't need an ADC when using a CH4 filter

same reason, only 20nm bandwidth

[cursive inlet]

But I imagine UV would be the opposite

[somber stratus]

certainly

[lean hearth]

Do you use a 16” rob?

[somber stratus]

Blue always benefits the most with ADC usage

[somber stratus]

yeah

[lean hearth]

I wanna save up for one but I was told they are a heck of a thing to move around

[sharp ridge]

oh yeah Tom do you set up the dob by yrself or need someone else to help plop the tube into the base

[somber stratus]

They do break up into pieces (the Sky-Watcher Dobs), but the main OTA is pain still

[somber stratus]

generally help from family member, but i have setup solo before

[sharp ridge]

Ok, my Moms thinking how tf do we two people place 70lbs in there

[lean hearth]

This looks nice it’s a sky watcher 16” dog and it’s collapsible would this work well and capture nice planetary

[sharp ridge]

thats literally what tom uses

[lean hearth]

That exact one
