Planetary Imaging

[flint siren]

Pinching on the optics can also do that but unlikely due to the clear direction of the effect.

[low oar]

Ok 😂

Saturn this morning

[ruby compass]

Cool

[lyric dome]

@livid sierra is this Barlow good?

[fathom oak]

yes. Is it the 2x or 3x version?

I have the 3x Xcel barlow and it's pretty good

[lyric dome]

2x

My scope can’t handle a 3x

[white prawn]

How? I have a 130/750 and a 3x is fine

[flint siren]

Duif is the replacement of Tom for ping spams it seems.

[thick heron]

@livid sierra How can I improve this Jupiter photo?

[sour cradle]

how did you produce something so shit yet so good

[flint siren]

Ethan trying to not be cringe (impossible) :

[lyric dome]

What’s mine again?

It’s a 6 inch

750mm

[lyric dome]

I’ll get the 3x next purchase e

I remember @candid flare did my calculation for my scope he said ideal magnification is 1.9x

[candid flare]

I don't remember that.

[lyric dome]

I do

It was like February

Or march

[thick heron]

This important matter needs to be in-Vesta-gated thoroughly.

[flint siren]

shut up dude that ain't funny

[lyric dome]

Yes it is

[thick heron]

Why so Cere-ous?

[lyric dome]

I think Ethan is saving us

[lyric dome]

Don’t be so Saturned off, I’m just trying to have a good time eh eh eh

[white prawn]

The Barlow you need is based on your ideal focal ratio, which in turn is based on the pixel size of your camera. Ideal focal length is found by taking your pixel size in µ and multiplying it by 7.

Native focal ratio is focal length in mm divided by aperture width in mm.

My 585 is 2.9µ pixel; 2.9*7 ~ 20.3. Native focal for Rio is 1000/203 ~ F4.9. Ideal divided by what I have, so 20.3/4.9 ~ 4.14and a bunch more.

My ideal Barlow is actually a 4x so 3x does it.

Now ... if I take my 3x and learn to use it with ADC, the resulting magnification is equivalent to 4x so the one ADC photo I have is pretty good.

[lyric dome]

Dang

Well my pixel size is 1.45

750mm

F4.9

6inch

150p

[white prawn]

Ideal is F10.15. So 10.15/4.9 = 2.07and a bunch more.

In your case 2x is ideal

[lyric dome]

Heck yeah

I made the right choice

Thank you man

[flint siren]

Not funny-cringe-dead meme combo. 🥀 🥀

[thick heron]

The simple joys of life come from keeping the barlow.

[teal sandal]

Wow

I need myself a big aperture scope

[low oar]

the moon 2 nights ago on june 3rd

please give feedback and suggestions to change

[flint siren]

Cooked like the last one.

Sharpness is better but oversharpened. Colors are still off. The overall looks good.

[olive saddle]

Alright that was pretty good lol

[livid sierra]

Nice

[keen ginkgo]

This is SHARP

[somber stratus]

I found it quite funny tbh

[left spindle]

finally assembled my rig, hopefully it will be clear tonight

[white prawn]

This should do it

https://planewave.com/products/rc1000/

[brisk yacht]

i finally removed a stuck screw out of my barlow

basicaly my barlow fell once and part of the screw in it brroke of which made it impossible to unscrew

ill be able to do some planetary again

[brisk yacht]

Ina

[low oar]

The Moon June 3rd

[lyric dome]

Detail is just crazy

[low oar]

Thanks

[flint siren]

Bro burnt the kitchen.

[ashen raft]

Where did all that color come from??

[low oar]

My camera

[olive saddle]

Iron Oxide and Titanium deposits on the moon's surface

[flint siren]

Why the glow though ?

[ruby compass]

YES

[lyric dome]

Ayyyy

[low oar]

It’s so subtle how did you notice 💀

Makes it look good

[flint siren]

well you go for a Bray Falls style it seems

[low oar]

🤷‍♂️

I’ve never seen his lunar work

[flint siren]

Diffraction limited lunar through the convection.

[low oar]

Huh

[flint siren]

?

[somber stratus]

Yeah that doesn’t make sense lol

[flint siren]

what doesn't make sense ?

[somber stratus]

Can’t be diffraction limited and infer seeing wasn’t great.

[flint siren]

1 µm moment

It was convection, just at 1 µm.

[hasty hull]

https://tenor.com/view/confused-stare-at-paper-gif-5257839294650729742

[low oar]

👀

[thick heron]

One easy trick to reach the diffraction limit: make it larger.

[flint siren]

Exactly.

[sour cradle]

exaxtly
Dont tell anyone but thats secretly the real reason im moving over to n band
Bad optics cant hurt me when the waves are 17 times longer

[teal sandal]

looks amazing i love it

[white prawn]

I've had clear skies and the moon has a red hue around it because of particulates in the air. Lovely, fantastic, I'm sure that any imaging I do right now will come out splendidly.

[low oar]

ohhh yea thats cool

[white prawn]

Not really, means seeing is absolute 💩 .

[low tendon]

@ruby compass

[low oar]

2 day lunar composite

[lyric dome]

We love theee

[low tendon]

just tranfering a file

[ruby compass]

Some of my sharpest lunar data ever.. (captured like 2months ago)

The line in the middle of the bigger line is only 500meter wide.. (and u can see it in this image)

[lyric dome]

Epic

Now see a honey bee

[native plume]

where is this on the moon

[ruby compass]

yeah

[lyric dome]

Wow

Amazing

@somber stratus you really outdid yourself on this

[thick heron]

[olive saddle]

So close! That is a shape stellarium.

[deft spoke]

did anyone here try to get any dwarf planets?

OMG

4WAHT

[low oar]

😂

[sour cradle]

yeah thats about the reaction the rest of us had

[low oar]

This morning

Aristarchus last night

Mons Rumker

[thick heron]

Happy birthday @hasty hull! 🎉

[somber stratus]

Happy bday willaf

[lyric dome]

Happy bday bro

[cloud copper]

Happy birthday willaf!!

[waxen solstice]

Saturn this morning 🪐

[ruby compass]

@somber stratus can u show the live view of vesta?

[candid flare]

im sure hes uploaded the footage somewhere

[ruby compass]

couldnt find any

[candid flare]

not in this server

[ruby compass]

no

[lyric dome]

It was probably so faint

[ruby compass]

Vesta is like mag 7 tho.. (about the same as neptune)

[lyric dome]

That’s pretty damn faint lmao

Imagine tracking it too

Probably had to download some software

[lyric dome]

Epic man!

I need to do some more lunar, weather here has just been so bad

[sterile marsh]

Tried to shoot the flat thing that was posted here but the only good results are the apenine mountains

[fathom oak]

flat thing?

the blue lake aka Ina?

[sterile marsh]

This

[fathom oak]

ah

[sterile marsh]

Ina is here

[fathom oak]

I don't see it in the image but yeah I know where it is

I attempted to shoot it once

barely got it

I will definitely revisit soon

[sterile marsh]

Discord ruins it so much😭

[fathom oak]

You on mobile or something? It looks completely normal to me

[sterile marsh]

Yes

Wait ill reprocess the data

Also happy to inform that im getting the 14 inch dobsonian telescope in 10 days

[hasty hull]

YO TY GUYS

I’m now an adult or smth

[sterile marsh]

Oh shi i didnt see that happy birthday willaf!

[hasty hull]

Appreciate it bro

[ruby compass]

mine

[sterile marsh]

Bro i Lost the data 😭😭😭😭😭😭

[ruby compass]

?

[sterile marsh]

I dont have the video

[ruby compass]

same. lost my best ever luna data

[sterile marsh]

I might Save it oli hope

[sterile marsh]

Its there but its smal

[flint siren]

Wth are you talking about ?

Standard sideral do the job and no it ain't faint, even at f/20.

It was mag 6 when we all captured it.

[lyric dome]

Well excuse me for making an educated assumption about a very small asteroid dwarf planet thing that is affected by the gas, giants gravity, all the time

😭

[flint siren]

Bro tf

'educated assumption' 🥀

[flint siren]

There you go. ^

[ruby compass]

Crazy

[low oar]

Did I get a good ina?

[flint siren]

Y'all have an obsession with this mid a** thing.

[low oar]

lol

I feel like there are other cool things

Biscuit just made it popular

[ruby compass]

@low oar i mean yeah but please rotate the image

Took me forever to find it due to rotation

😭

[lyric dome]

@flint siren no offense ur kinda being a dick

[low oar]

Hasn’t he always been

[lyric dome]

Yup

[lyric dome]

“Tf are you talking about?” There was no “all captured it”, without a huge scope and good mount it’s not doable. Not my choice I can’t invest my entire paycheck on Astro gear

[thick heron]

Vesta is the brightest asteroid in the night sky, brighter than Uranus at it's brightest. The challenge is resolving it's shape. It's been done with telescopes as small as 10".

[lyric dome]

Which is still pretty big for an average Joe if you include a mount?

[lyric dome]

That was satire btw

[olive saddle]

I figured lol

[lyric dome]

Haha

[thick heron]

Most telescopes will be big to an "average Joe".

For someone in planetary imaging a telescope around that size is probably their second telescope.

[lyric dome]

Cool.

[sterile marsh]

Todays morning Saturn

[low oar]

currently mosaicing

Terrible seeingh

i got the moon rising though

[olive saddle]

that's a neat shot, the moon between the cooling towers

[low oar]

thanks

it was with a gskyer scope

[rugged knoll]

how is that with a scope

it's so wide

[flint siren]

I'm offended. All i said was "what is the link between gas giants and resolving, bro on some good stuff".

[flint siren]

I did it at 8", no big scope involved.

[brisk yacht]

Ooo that's a nice result

You can see Ina pretty clearly

[lyric dome]

That is not what you “said” but I’m leaving it.

[lyric dome]

He is probably very far away

[rugged knoll]

I mean like compared to the moon too

That's wider than my binos

[lyric dome]

Oh fr?

Could be the different in lens he is using

I know some make farther objects take up more of the screen, and some do the opposite

I’m not an expert tho

Yosh gonna pull up cursing me out again if I say anything off

[tiny topaz]

What do you use to create mosaics? I wanted to try one but maybe I’ll hold off if I need photoshop or another paid program

[sterile marsh]

hey does anybody know how to shrink files

[low oar]

The towers is with a dslr and the moon is with the scope

[low oar]

What do you mean

[fathom oak]

you can compress the data but it makes the quality worse

[flint siren]

Having a convo in this place is indeed pointless.

[tiny topaz]

What program do you use to create your mosaics? Like stitch the panels together

[fathom oak]

we got Zach and Yosh beef before GTA VI

[lyric dome]

I don’t have beef with him, his attitude is just very negative for the environment

[digital steppe]

https://tenor.com/view/stop-fighting-hose-parenting-hose-off-gif-12003125

[lyric dome]

Like I said, not fighting. Just made a statement

I’ve never experienced disrespect of others in this community so it stands out

[low oar]

I do it manually in photoshop

[tiny topaz]

Ah okay fair enough I’ll have to look into using that

[livid sierra]

Photoshop also has a feature to just do it automatically, and Microsoft ICE works well too

I find Photoshop works best, with some manual touchup afterwards

Not necessary to do it manually imo, manual correction I need to do is almost negligible

[sterile marsh]

duif what did friderick say?

[livid sierra]

Yeah sadly he doesn't have any telescopes for rent or to lend

[sterile marsh]

oh thats unfourtunate

[livid sierra]

Yeah, but was to be expected tbh

I also emailed a Croatian store but same answer, as expected lol

That one gave me a follow on ig tho

Cool guy

[left spindle]

Forgot to post it here [114/900 scope, webcam, untracked, almost 800 frames stacked]

Gso 2x barlow too

How do i improve my images to make them sharper, i have reached the max magnification limit, seeing is okay here, bortle scale is 4, should i stack more or less pics? also how do i fix the onion skining?

[thick lotus]

Generally if you are at the limits of FL already, trying to stack only the very best frames is the ticket for improvement (so long as you have enough good ones) so cutting down on quality that still gets to your stack might help a bit

well, not cutting down raising the bar rather is what i mean

[flint siren]

'negative for the environment'

Ok i'll stop

[flint siren]

Most just say nothing out loud and keep that for themselves, sadly.

Somes have something i'm sure. (Won't say names)

[lyric dome]

Well, I believe the ability to keep your emotions to yourself is mature, thank you for relaxing though. No reason to spread hate even if they are wrong, constructive criticism is how we learn. Not bashing people

[flint siren]

Hell nah bro i wasn't badhing you lol. Just wait for someone to do it when they will have enough. Can't talk about maturity either.

Constructive critisism doesn't seem to work apparently.

[left spindle]

I see, ill try to get more frames next time

What abt the onion skinning

[low oar]

Well here’s my flower moon so far

[sterile marsh]

Guys i am happy to say i just collected the money for the 14 dobson

[livid sierra]

There’s a forum for lunar imaging https://discord.com/channels/794642864218439681/1019760880231125132

[thick lotus]

Onion skinning may be bit if over sharpening going on hence why maybe keep smaller percentage of frames so you only get very beat.

[left spindle]

Ahh i see, so onion skinning isnt related to exposure

[rugged knoll]

thr last image was in 2024

[thick lotus]

You are more prone to it if you have too low exposure, specially if rolling shutter but, generally you never have it so bad that you get it even before sharpening so you can control it by how much you sharpen even in worst case

If histogram looks ok you have done what you can and rest is just limit of how much you can sharpen with that data

With moon it would be very rare to under expose cause there is whole bunch of light so i doubt it would be that

Usually it happens when trying to max out frames on dimmer planets

[livid sierra]

Great reason to fire it back up again

[left spindle]

I see, thx for the help, really appriciate it

[lyric dome]

What’s the best Jupiter live view? I just watched Astro biscuits one, looks insane

[shell epoch]

Best view is irl

[thick lotus]

eye is really, really good image processor you do get planetary views that trump camera live view usually on eyepiece

Camera live views are sharp as well though so long as you have patience to keep scale small enough

Have it so that it looks like pin of a needle on arms length like on visual view and usually it looks good even in weather

[olive saddle]

There's a really neat video I've seen on Astronomy sketch's with an 18" Binoscope, it's mostly nebulae but they guy also presented a live view sketch he did of Jupiter and it looks incredible

https://youtu.be/IaQgP_md1Dg?si=T3tnfFR9LE6u2ttG

[thick lotus]

I have seen photos of people projecting Jupiter like you used to do sun on 1 meter Astro fox :p

Huge folded Newtonian that one, basically

Most of the time if you want to actually visually observe from live view though, just leave out the Barlow, small sharp image is much nicer than big blurry one

Same goes most often for eyepiece too unless it is super good night

[lyric dome]

So interesting

[thick lotus]

I have never, ever had seeing this good, would love to have it once in my life: https://youtu.be/CAQjpW7DlDY?si=XonUeLDhbK2mthFS

[lyric dome]

That’s so good

This is my best live view with a 6 inch, if I had a bigger scope it could have been special man

[thick lotus]

Trust me in good seeing it is special on 6 inch scope as well

[lyric dome]

It’s sending

I think colimation was slightly off but

It’s an animation

[lyric dome]

Sadly I never looked myself

Only filmed

[thick lotus]

My seeing is more often more like this (excuse over twelve year old video though)

https://youtu.be/8M21_wdEjsQ?si=S6hTvvoHHcyjQYzp

[lyric dome]

Ooooo

Holy crap!

That’s really good!

My average is so bad

[fathom oak]

it's so weird seeing Jupiter with only one dark equatorial band lol

[thick lotus]

There was that one time when the other one disappeared

[livid sierra]

You could use softer/less wavelets for a more natural look

[thick lotus]

Looked super weird yeah

[livid sierra]

This is quite oversharpened

As in you sharpened but no more detail gets brought out

[thick lotus]

With almost any aperture scope you can still get sharp and nice looking Jupiter images just need to be fine with letting image scale be smaller

Get more light with smaller aperture and better exposure and less breakup when you sharpen

[fathom oak]

got any pictures of that perhaps?

[thick lotus]

I am actually not sure let me dig around, ton in the internet but I am not sure if I have any of my own, not sure if i had anything to take pictures with, if i did it has been from eyepiece with point and shoot camera

It was just after Christmas in 2010 when it happened I think that is what i recall best anyway

Might have been bit later, march or April or so

[fathom oak]

lol I was 1 year old then

[thick lotus]

My first actual images are from 2012 so i was too late

I could swear that it also happened in early 90:s but I did not have a telescope back then yet so. Never saw myself, it was talked by a lot by visual folk though

I do not even remember which of the belts disappeared then

[rugged knoll]

The hell

Do you live 35km high

[thick lotus]

That was from my balcony on quite good really cold night on old blue tube SW 200P

No idea what the camera was, maybe modified MS lifecam

[rugged knoll]

My seeing sometimes looks like this

Oops

Wrong image lmao

[rugged knoll]

why did the screen recording compress it so much wth

[thick lotus]

That is most nights for me too, if you are able to, place that has no asphalt or concrete underneath can help, over forest or maybe frozen lake

So that you have calmer air usually it is the very lowest layer of air that does that sort of thing

[rugged knoll]

what kind of mystical place do you live in

frozen lake and forest

[livid sierra]

Quite wobbly lol

And blurry

Also is that like 5fps?

[thick lotus]

Might well be

It is either point and shoot camera or ancient MS lifecam

[livid sierra]

Really doesn’t look that good like no offence but that’s like 6/10 at best

[thick lotus]

That is usually the best you can hope for here, maybe two - three nights better

[rugged knoll]

that's about as good as my seeing gets😭

ive had one night where it looked like that

[thick lotus]

Strangely best i have ever had usually has been in between clouds

[rugged knoll]

lost the data sadly

I got this out of it, wish i could do a reprocess

[thick lotus]

Point and shoot with plywood jig, was what i had first and then people started to modi’s Philips webcams and those actually worked really good

FPS was low then too around 15 I think at best

All Philips spec 900 disappeared from used market lol

Spc*

[low oar]

Voyager 1

[ruby tartan]

Mine

[fathom oak]

wow what scope is that with?

[ruby tartan]

GSO 12" dob

[fathom oak]

very nice

[lyric dome]

First one is same night, this better?

[livid sierra]

That second image is a great example of what not to do, the first one looks good yeah

Quite nice, looks like compression is kind of ruining it though

[limber reef]

This year has gone so fast its nearly planet season again

[lyric dome]

Thank you! A compliment from a top planetary photographer means a lot

[low oar]

Dang dude

[lyric dome]

Yeahh the 2nd one I was just saturating

[native plume]

first image looked like my first attempt on jupiter

[rain mauve]

This is my first try on jupiter

Using phone and a telescope, it was really bad seeing

[limber reef]

My first attempt

Could do with better focus and integration

Maybe better camera too

[low oar]

Highly Detailed Image of The Strawberry Moon

[white prawn]

I need to have wildfires stop and get some good seeing.

[livid sierra]

Holy crap that must be at least 1,000,000 pictures right

You got some weird white spots in the sky there

[white prawn]

I think I'm going to take a longer image of the moon at some point and get a decent MM.

I could probably combine all the frames from a sequence that I took on a night or so ... I feel like just doing one single long vid would be better/easier

[low oar]

Stars lol

[low oar]

Only 14,520

[livid sierra]

Nice stars

[low oar]

Thx

They look fine zoomed out

I don’t mind

[livid sierra]

Did you actually just draw these stars with the brush tool?

[low oar]

Naw just some png off google

[fathom oak]

why even include it in your image lmao

[livid sierra]

Ain’t no way

[thick heron]

If you're taking images off Google you should attribute the source at minimum, but just don't do that in the first place. They aren't that important for the image.

[low oar]

Instagram likes it

And it’s just dots

I completely change it

[fathom oak]

at least take your own star pic. It takes 2 seconds and looks much more natural than these clipped MS paint stars

[low oar]

Ye

It was already 2 in the morning and I reshot my mosaic 3 times

I was good for the night

[lyric dome]

I made the same mistake Kenny and everyone criticized me haha

It’s probably better to not

[low oar]

Naw its chill idc lol

[livid sierra]

You captured thousands and thousands of photos lol

Like really I’m not trying to hate if you just want people to like your glowing moon pic be my guest but always that caption like lol

Does your finger hurt from pressing the shutter thousands and thousands of times?

[ruby compass]

hello everyone

[low oar]

Are you joking?

[livid sierra]

Bruh yes my guy I am

[low oar]

😞

[fathom oak]

lmao

[livid sierra]

Of course I don’t think you pressed the shutter a million times

[ruby compass]

how.

[livid sierra]

But the instagramers will think that

And they eat it up

But that’s what you aim for is it not?

Making people think you spent the whole night shooting the moon to produce the glowing strawberry moon picture

[low oar]

Idk

Just the way I word it

[livid sierra]

You took a video lol

You pressed record in sharpcap and your cam started recording a video, that’s literally what it is

[low oar]

I ain’t wording that in a description

[livid sierra]

Technically yeah you took a million photos but by wording it as “I took thousands and thousands of photos” is just a clickbait way to get likes and views

Like yeah the instagramers will eat it up but here you are not fooling anyone

[low oar]

Thanks?

I guess

Idk

Not that deep

[fathom oak]

lol what is going on here

[low oar]

Brotha dogging on me

[livid sierra]

Really man I’m not tryna dog I just have an ick for this clickbait type of imagery and captioning

Don’t mind me just keep taking the glowing moon pictures

[low oar]

Allllllright

Here

[livid sierra]

Beautiful my man

Also why do you start every word in your caption with a capital letter? Genuine curiosity I sometimes see people do this online in like messages and I always thought it was OCD or something but you don’t seem to do it when just chatting

So please enlighten me

[low oar]

Idk tbh

[livid sierra]

Must be almost as tiring as pressing the shutter a thousand times loool

Last joke for now

[fathom oak]

bro lay off of him lol

[livid sierra]

Come on man nothing wrong with joking around a little

[low oar]

💀

[fathom oak]

I agree it's cringe but let him be

[livid sierra]

I’m sure he can take it

[low oar]

Listen to yourself bro

Holy 😂

Bruh the New York mirror just posted my pics and didnt credit me 💀

[livid sierra]

I think I was being very civil but if you think I was being a dick then I apologise

[thick heron]

Maybe they just got some PNGs off Google.

[low oar]

I sent it to them

[fathom oak]

||seems to be a common theme||

[low oar]

Alr

[livid sierra]

Just gonna say one last thing you are posting glowing moon pictures in an environment of mostly people either taking lunar closeups or high res planetary images. Maybe the glowing moon pictures are the odd ones out

[thick heron]

Now that I'm able to look at it from home, I think the red channel is not aligned with the others. There's a red ghosting off to the side of many features.

[livid sierra]

I think that much is obvious there’s a strong 3D effect going on but the instagramers won’t notice Ethan

[fathom oak]

duif throwing shade left and right haha

[low oar]

💀

[lyric dome]

Atleast it’s constructive criticism unlike someone…..

[flint siren]

Duif already got a girlfriend zach

No need to be like that

And tom's not interested

[fathom oak]

bro who invited you here

quit adding to the drama

[flint siren]

Or just stop being like that, that ain't constructive behavior

[fathom oak]

you talkin to me?

[flint siren]

Ofc not

Ya ain't zesty

[fathom oak]

what is it with you and Zach bro just lay off already

[lyric dome]

lol

Never said anything abt you

Yosh

And I have a girlfriend lol

[flint siren]

That's the worst answer i've ever seen, lower than my lowest expectations. GG

[fathom oak]

dude if you're gonna be this negative for no reason then see yourself out

[lyric dome]

It’s sorta irritating because I had huge respect for this guy, he caught Uranus’s rings, it’s unfortunate

I find getting the rings super cool

[keen ginkgo]

Ill tell u what to do. If u cant take a proper image of the stars, take a blank image (like a dark flat). Bunp up noise to max and then desaturate

Thats what i used to do in my early days

[tiny topaz]

honestly kind of genius

[keen ginkgo]

What can i say

Im just that guy

[lyric dome]

That’s rly smart actually

[keen ginkgo]

Wait lemme find an image where i used that

[low oar]

😭

[keen ginkgo]

Like you cant tell me this doesnt look real

[shell epoch]

That's genius

[keen ginkgo]

Im the smartest dude in asia for a reason

[lyric dome]

which is better??

[low oar]

ide say you could do a fov in between the 2 and it wont look bad

[low oar]

Got my moon shot printed

[ruby compass]

W

[olive saddle]

That's so nice looking

[fathom oak]

all fun and games until someone tries to platesolve it

[compact bough]

Looks very clean

[keen ginkgo]

Very nice!

[keen ginkgo]

Surely no one in insta has enough time to do that

[flint siren]

Or just get real stars

[keen ginkgo]

Yea i couldve, but getting this many stars in the centre of a white b9 was kinda hard, considering this was one of my first moon images

[flint siren]

why add fake stars though ?

[keen ginkgo]

I was 13 at the time, who knows

[rain mauve]

This is my strawberry moon here

Using 300mm focal length with 1300D camera

[terse night]

Is that Uranus image in your pfp yours? What's the aperture of the scope?

[flint siren]

That's a comp and 8".

[terse night]

Yeah it did look way to clean

[low oar]

That’s good for 300mm dude better than I’ve done at that length

[lyric dome]

Awesome

[rain mauve]

Thank you

[candid flare]

anyone got this? https://bintel.com.au/products/zwo-atmospheric-dispersion-corrector-adc-2

what are thoughts on it/

[sterile marsh]

Saturn and titan yesterday

[deft spoke]

i see titan, rhea and dione

nice!

[lyric dome]

Nice bro, I got this the other day

[summer pebble]

Eclipse on Saturn by Titan

[fading plume]

It’s fine. Does the job.

[lyric dome]

i hate bad seeing

[left spindle]

😭

[lyric dome]

How close was mars in ur photo

[left spindle]

Opposition

[livid sierra]

Doesn’t look that bad

[lyric dome]

Thanks man! There was a thin cloud infront of it kinda annoyed me, I stayed up for Saturn and Venus but they were completely behind clouds lol

[white prawn]

Agreed

[livid sierra]

That really sucks, especially when it's time that you could've been sleeping sound lol. I'm hoping to get Saturn and Venus tomorrow morning too

Definitely gonna take some time to take a nap sometime tonight though because I slept terribly last night

[lyric dome]

You understand so well haha

I’m so tired, and work tmr morning, even if it’s clear can’t risk oversleeping

[whole osprey]

Me when bad seeing.

[candid flare]

ADC purchased

[sterile marsh]

New beast arrived

Compared to an 8 incher

[candid flare]

👀

[white prawn]

I've seriously thought about getting a bigger OTA. not going to happen unless/until I have a building for it.

Simply because I am NOT hauling that thing out every time it's nice out

[low oar]

It’s worth it

[livid sierra]

Is the planet in the room with us?

[lyric dome]

The what

[lyric dome]

I saw ur Saturn bro, insane

Better than toms…. So fr

[livid sierra]

The planet because we’re in the planetary imaging forum lol

[livid sierra]

Much appreciated

[sour cradle]

well
yeah
its called earth

[ruby compass]

Some of my best data ever. (Old data)

[ruby compass]

tried combining the duoband data (for clouds) with broadband data for details.

[left spindle]

Thats actually pretty good

[left spindle]

Woaaahhhh, which scope do u have?

[ruby compass]

8" dob

Untracked

[somber stratus]

Why duoband?

If it passes red (either Ha/Sii) then it's not going to be great for clouds.

normal blue filter is best.

[ruby compass]

Idk. Just tried it ones for fun and it actually worked.

[ruby compass]

@somber stratus clouds look good here tho

[ruby compass]

Would just the bluechannel work? (I have a color camera and no blue filter)

[somber stratus]

yes but it'll be noisy as you only have 1/4 of the signal compared to a mono sensor and B filter

[ruby compass]

True

How much was your scope btw?

The 24"

[somber stratus]

3.5 used

I'm sure I've said before

somewhere

[sour cradle]

3.5 dollars? Man i could only get a 2 and a half inch scope for that price.

(i actually have like, 11 2 and a half inch mirrors at that price)

[left spindle]

why is the res so bad even with an 8in?

[ruby compass]

Bad??

[left spindle]

heres mine with 4.5in

[ruby compass]

@left spindle ur calling this bad?

[left spindle]

thats good

[ruby compass]

Mine wasnt during opposition

[left spindle]

Ah i see

i wish i had an 8in 😭

or a better cam

[flint siren]

Well it ain't great

[ruby compass]

You are not a human tho Yosh.

[rugged knoll]

reprocess

[rugged knoll]

old process:

(this was from march)

[white prawn]

Reprocessed has a bit of edge rind on the right.

[rugged knoll]

i did this to it

i think i just messed up tbh, gotta do a third reprocess tomorrow

or maybe ill throw it in share your data

[white prawn]

Mars is ... not kind when it comes to avoiding edge rind.

Not kind at all.

[rugged knoll]

heres what it gave after winjupos

it is already sharpened a bit

[white prawn]

Like me, getting rind "right out the gate".

[rugged knoll]

whats a good scope for the planets

im gonna get a 150mm f/4 soon to replace my horrible collimation flextube but thats still a dso scope

[white prawn]

Eh. That'll do. If my 130 F/5 can do planetary, your 150 F/4 will be fine.

[rugged knoll]

(on a tight budget, i wish i could get a 12" dob or smth)

[rugged knoll]

this was with the 150 f/5 flextube

[white prawn]

I'd say it's performing then. You're struggling with edge rind because Mars does that. Try Jupiter & Saturn when they come up.

[rugged knoll]

the new scope will only be a bit better, it was designed about a thousand times better but it is the same aperture, and aperture is king

[white prawn]

You could get this

https://planewave.com/products/rc1000/

[rugged knoll]

ive done some a while ago

[rugged knoll]

dont wanna spend too much cause well obviously i dont have too much, but also my seeing is VERY bad where i am so its kinda pointless to spend a lot

[rugged knoll]

this is the best my seeing gets

yea even an 8" is too much

[digital steppe]

Even cheaper https://www.explorescientific.com/products/explore-scientific-10-inch-hybrid-truss-tube-dobsonian-telescope-dob1045c?srsltid=AfmBOoqN4NwuAgEbi_KQwihWhCcbljQD87jhBdEGo_SngJt33OR7s5No

[digital steppe]

Only 650 for a 10 inch

[rugged knoll]

sold out but thats a damn good deal

[rugged knoll]

https://www.explorescientific.com/collections/all-telescopes/products/explore-firstlight-10-dobsonian-telescope-package-fl-dob1005-02-pk even less

[digital steppe]

Or that, but I like trusses because they are easier to transport

[rugged knoll]

im not putting it in a car or anything, only carrying it like 50 meters its fine

[digital steppe]

Ok

[white prawn]

Nice work, you're getting it.

If your seeing is bad, then you got those on some decent nights. I've done imaging on bad nights, it's good for the laughs.

Mine is an 8". You can get some really good stuff out of a 4" if you know how to work with your stuff.

[rugged knoll]

my best views of jupiter ever were actually with a 4.5"

it was one winter night when i was a beginner, somehow the skies were like perfectly frozen

[sterile marsh]

Hey can anyone tell me if my ASI 662 would work good with the adc

This is without the adc

[dark cargo]

Are you using a UV-IR cut filter? Looks like you aren't, so I would recommend buying one first. ZWO or playerone should be like 30 bucks I think?

Basically your camera is really sensitive in NIR light(redder than red) but those larger wavelengths can't be focused into as small of a point so you do get less details on things. Also they mess with the colour balance making everything look red.

I have the same sensor, and this is how a nebula looks like without the uv-ir cut compared to a galaxy I took with one: Much more colourful.

ADC would help, especially if planet is lower on the horizon, but at this point definitely get the uv-ir cut first.

[sterile marsh]

I have an UV/Ir cut

[dark cargo]

if you were using it, how low was saturn on the horizon? Ideally you want to shoot when the planet is higher than 30 degrees altitude as otherwise you will be shooting through a lot more air(which also will make things look redder/oranger).

[sterile marsh]

Ill check the altitude and i used an Ir-pass filter

[ruby compass]

hi yall

[sterile marsh]

Saturn is higher than 30 degrees

[fathom oak]

you just said you have a UV/IR cut filter, and now you're saying it's an IR-pass? Or do you have 2 filters?

[sterile marsh]

I have two filters

[dark cargo]

Ahh well that is why it looked that red. Probably better to use UV-IR cut, or even both at the same time. imx662 is very sensitive to NIR light which you will get a lot of with a IR pass filter.

[sterile marsh]

I was thinking on buying an ZWO 678mm

[dark cargo]

I don't think you have a camera problem here imx662 is same technology as uranus-c etc which is basically the best you could get. Try using UV-IR cut and wait for better seeing. If it's not seeing its probably some other issue like not actually being collimated where the camera is placed or focus being wrong.

[sterile marsh]

So your saying that i have the same technology as an Uranus-C

[dark cargo]

yes the camera is great, so your issue lies elsewhere.

[sterile marsh]

So maybe the issue is that i dont have the adc?

[dark cargo]

I think you have to solve this with skill instead of money.
TLDR: make sure you are actually collimated and focused then get lucky with the seeing.

I think saturn is also fairly far from earth + with flat rings so that doesn't help

[sterile marsh]

Both things were perfect today the collimation and the focus too

[dark cargo]

If you ignore the IR pass filter that does not look right to me. See what happens when you shoot with the uv-ir cut. The IR pass is more of a "seeing is terrible and I have a big aperture" type of thing afaik?

[livid sierra]

An ADC can improve your pictures and it's essential when imaging the planets at high magnification and at low altitudes, but you won't have any use for it without a proper Barlow first.

I don't know how you think a ZWO 678mm is going to fix your issue.

[dark cargo]

Oh if not barlow you probably want one.

Max barlow power = 7 times pixel size in um(2.9 in your case) divided by focal ratio

The picture does look pretty soft without the barlow, which is why I think there might be some collimation, focus or seeing issue. If we ignore the IR pass filter since I don't quite know how much I can blame it for, but it definetly does not help.

[sterile marsh]

I have an 2.5 times GSO apo barlow

[livid sierra]

Would be a good idea to use it while imaging.

[ruby compass]

does anyone here know how to derotate?

[sterile marsh]

Yeah but while i image it looks blurry and noisy

[ruby compass]

get perfect colimation (laser colimators need to be colimated) and no shit that its going to be blurry if u have bad seeing or its really low on the horizon

[livid sierra]

That sounds like bad seeing, of course when you are at a higher magnification, the effects of bad seeing become more apparent. The image also becomes darker, because you are at a slower focal ratio, which is why it looks noisy. This is why you stack!

[sterile marsh]

35 degrees above is not low

[livid sierra]

35° is pretty low

[sterile marsh]

Really?

[livid sierra]

Yes, really.

Also relevant is if the planet was actually at that elevation at the time of imaging, or if it reaches that altitude in general.

[ruby compass]

kinda is

[sterile marsh]

my new best saturn

[ruby compass]

Crazy data Tom. (your data processed by me)

[fading plume]

45 degrees is my cutoff point for too low.

[ruby compass]

oakley.

i have a question

where/how do i derotate?

[fading plume]

Winjupos, there are guides online.

[ruby compass]

alr.

could u try or nah?

i have the data stacked already

[fading plume]

Sure why not

[ruby compass]

alrr

do i send in dms or here?

[fading plume]

Oh I do it, sorry busy for the next week

[ruby compass]

busy rn?

[fading plume]

Yeah got classes in an hour and I have to get ready

[ruby compass]

alr

[somber stratus]

lol

mfw the average meridian crossing is 38° here

[somber stratus]

Don't remember sharing this set but was a while ago

Jupiter and Sun Conjunction ☀️

Tonight on June 23rd 4:00am in the morning, the planet Jupiter will disappear behind the Sun for approximately 15 hours, when it will reappear at 7:00pm in the evening on the 24th

If I did my research right, I’ve calculated that this event will not happen until 2031 and 2032 where the transit will happen ex...

[sour cradle]

tom
every time you say shit like this it just helps the case that you are using a deal with the devil to get better data

[thick heron]

Around 30° is where I draw the line between low and okay in normal circumstances.

But if it's Mars, Jupiter, or Saturn and it's just coming out of solar conjunction I'll go for it as soon as it rises above my horizon.

[ruby compass]

Yeah it was a long time ago

[ruby compass]

@rugged knoll i sent u the data in dms

[fathom oak]

Does a Saturn process look better normal or color balanced?

[ruby compass]

normal

color balenced looks ir

[ruby compass]

@fathom oak the new Vera rubin observatory images are insane.

[shell epoch]

I like the tan version more imo

[low oar]

Saturn this morning

[ruby compass]

cool

***Jupiter 26/02-2025 ***

[low oar]

How do you view mercurys tail?

Time of year? Filter?

[somber isle]

You need a narrowband filter

Also it's usually when it's near the horizon

[thick heron]

Likely need a sodium 589nm narrowband filter unless the sky is incredibly transparent.

[fading plume]

As opposed to when it’s directly overhead just before sunrise?

[low oar]

How much do those cost

[flint siren]

275€ for the unmounted 10nm bandpass filter

[thick heron]

These aren't normal astronomy filter sizes so up to you to figure out how to mount it.

[sour cradle]

From where? Edmund or some shit?

[flint siren]

Aluxa

[ruby compass]

Sodium filter

[sterile marsh]

@ruby compass

[ruby compass]

Cioo

Cool*

[low oar]

Is it possible to image without it or no?

[flint siren]

Not possible unless you are at Cerro Tololo/Paranal or at La Palma. You would need insane transparency to go and try broad band

[summer pebble]

a very distant mars

[sour cradle]

see and this is why aliexpress is best

tangsinuo, doesnt have a 590nm, but other places do
and they much cheaper

[flint siren]

But have unwanted reflexions. Aluxa is trust worthy.

[livid sierra]

Unwanted reflections as well as a higher probability of having unwanted leaks. They have much worse QC. There’s a reason they’re so much cheaper.

[sour cradle]

so far, ive never had an inaccurately described filter, all the sellers ive looked at have been honest
they are, broadly lower OD, but thats not so much of a killer when its something you can afford versus just never getting

[flint siren]

Someone tried those 'cheap' filters for the sodium cloud of Io and it turns out they're trash.

[sour cradle]

then they should find a better seller

[flint siren]

Aluxa.

[sour cradle]

idk
ill take my chances that after 15 different cheap filter sellers one of them will turn out good

[livid sierra]

Yeah, they’re honest in that they literally state themselves that not every filter will be the exact same, and might have a different transmission graph than from the ones they show on their page.

[sour cradle]

ive never had an optical filter not be the same as the transmission data they provide, idk i just think you are looking at bad sellers

like if you have had bad experiences i get that

but those are just bad experiences

[livid sierra]

It was Tangsinuo.

[sour cradle]

where exactly?

[livid sierra]

AliExpress.

[sour cradle]

right
where does he say that the transmission might be different?
unless you are misconstruing "Transmission curve:(If you require the detailed transmission data,please contact)"
because yeah
the graph doesnt show you the actual numbers that are behind the datapoints

did you think that was like "yeah we have a fake graph, but if you email me ill show you the real graph"

[livid sierra]

Of course not, but it’s to be expected that with the low prices they offer there is much less possibility that their quality is as consistent as that of more expensive filters.

https://www.ultravioletphotography.com/content/index.php?/topic/5518-new-tangsinuo-filters-which-to-get/&do=findComment&comment=58402

There is a difference from glass melt to glass melt.

[sour cradle]

im looking thru this thread, and i see that guy reference different transmission between batches, but i dont actually see the post where he posts the different batches, do you remember which one it is?

he says "those two QB21 AR filters I bought at the same time in different sizes differ in their transmission spectra."
does he mean the two different thickness ones?

listen at the end of the day if you dont trust cheaper stuff thats your choice, i get why it just feels irrational to me sometimes

I found this thing recently

300pds on an az mount

[thick heron]

Tethys casting a shadow on the rings.

[ruby compass]

How??

[teal sandal]

This Saturn looks insane

I bet it will look even more crazy when the rings have more tilt

[lyric dome]

@somber stratus hey man, just reposted ur post, I’m wondering like what mount do you use for that scope? Did you build it? I would just like to learn more about your gear process

[lyric dome]

Focal length?

[summer pebble]

3000mm

[lyric dome]

Damn that’s crazy

What Barlow?

Is 40 degrees at 5am good?

[summer pebble]

Just a simple Celestron Omni 2x

[lyric dome]

Damn my normal fl is 750 so with my 2x I can get 1500

That’s it though

[summer pebble]

Hey as long as you’ve gotten promising results

[summer pebble]

Seems good to me if there still isn’t sunlight

[fathom oak]

It doesn't have to be astrodark but the more daylight there is the worse your SNR is

[lyric dome]

I mean isnt higher in the sky better even if there is sunlight

To an extent

[lyric dome]

I have been busy for the last month, this was a month ago

Without the new 2x Barlow

So I’m excited to see results tn

I got a 150$ Barlow

[summer pebble]

Hey is that a Titan shadow transit??

[lyric dome]

So it’s gonna help I hope

[lyric dome]

Yeah

[summer pebble]

Looking pretty neato

Nope

Saturn and cat

[fathom oak]

wait that looks like my cat lol

hol up lemme try to find a pic

[somber stratus]

meh, for Venus yeah but other planets you lose SNR. Saturn is basically unusable in the day

[somber stratus]

It's just an alt/az base with Servocat motors. I didn't build it, bought it second-hand.

[lyric dome]

Thanks for sharing, how much was it?

No stress to share

[ruby compass]

Yeah

[woven kite]

my powerseeker is a pain in the bum

how do you guys do the sliders?

i just play around with them to my liking

[ruby compass]

Same

@woven kite however i find astrosurface better

[woven kite]

alr im checking that out

[ruby compass]

Yeah

[lyric dome]

There are no short cuts with AP, you have to self teach because looking good is subjective

[fathom oak]

there are some good tutorials on youtube. You have to play around when the sharpen and denoise values also, not just the sliders.

[lyric dome]

Slider 4 from the top is important tho

[lyric dome]

Oh yeah frog I found my laser sight

I’m going out tonight

youtube tutorials are your friends

[somber stratus]

IR vs OSC (converted to mono), 4 mins apart. Same wavelet settings, focal length etc

if anyone was in any doubt as to the seeing benefit of IR

[cloud copper]

What ir filter do you use?

[somber stratus]

I use multiple, but this session in particular was the Astronomik 642BP

[fathom oak]

that's actually crazy

[somber stratus]

642-842nm ish, it's not a longpass so dispersion isn't so bad.

Baader RG610 or 685 would do pretty well too.

[fathom oak]

got any recommendations for IR filters for planetary?

[somber stratus]

Which do you have currently?

[fathom oak]

oh wait nvm do you need a mono camera for IR filters or can OSC work?

I don't have any filters currently

[somber stratus]

OSC can work, but it's slightly less efficient. The bayer matrix becomes transparent above ~850nm so IR850+ and CH4 are unaffected by camera (give or take a few %)

But anything shorter wavelength you'll start to be hindered

[thick heron]

If you care about UV it will be an issue.

[fathom oak]

ah ok

[somber stratus]

yup

UV is suicide with an OSC cam

IR is usable

[somber stratus]

I'd probably say 685, 850 and CH4. Those can do pretty much everything

Can swap out the 685 for a 642BP arguably, but maybe then you'll need to pick up a RG610 for that extra signal should you need it.

[sour cradle]

well
shouldnt you use different wavelets with the different data?

[somber stratus]

I use the 610,642,850,CH4 fairly regularly. I wouldn't bother with anything in the 700-800 range (e.g 720 longpass or Astronomik 742) unless you care about Uranian rings.

[fathom oak]

why am I seeing like 8nm CH4 filters lol I thought IR was like 780+

[somber stratus]

Sure, but defeats the point of the comparison of the seeing benefit.

[sour cradle]

8nm bandwidth

[fathom oak]

oh ok thanks

[somber stratus]

I'd get a 20nm CH4 tbh.

8nm is hella dark and more expensive

[sour cradle]

oh really
that wide works?

[fathom oak]

I'm seeing a lot of ZWO ones. Does the brand matter a whole lot?

[somber stratus]

Yeah, it's not like Ha in DSO imaging. The absorption is quite wide.

1 sec

~20nm

[somber stratus]

Not really. Most use the ZWO, including myself. Works fine

[sour cradle]

we both know im gonna tell you to buy the tamgsinuo one but as much as i hate zwo their filters prob work fine

[thick heron]

I've used the ZWO CH4 for almost a decade. Works good.

[sour cradle]

plus they only have a 30nm wide one for that band so
not ideal

[somber stratus]

I'd probably get a 685 before the CH4 tbh, if you have zero IR filters thusfar @fathom oak

or 642, pretty similar

[thick heron]

My 685nm filter is the single longest lasting item in my setup so it's a good one to have.

[sour cradle]

oh no wait they do have one thats 20nm
its 2 and a half dollars cheaper than the zwo one
so thats not a good deal

[fathom oak]

oh?

[somber stratus]

I've somehow avoided picking one up. Got many around the 685 mark but never felt the need to pick one up. If I had no filters, it would probably be my first.

[sour cradle]

yeah 685 is pretty versatile

[fathom oak]

but that's not even IR though

[somber stratus]

610,642,720,742,850,CH4,1010 is all I have

[thick heron]

It was my first filter, before RGB filters.

[somber stratus]

It's a longpass.

90% of the transmission is in NIR

[thick heron]

685, 720, 850, CH4, 1010

[fathom oak]

but at 685nm it would be more affected by an OSC bayer matrix correct?

[sour cradle]

yeah

[thick heron]

Guess 742 counts too but it's a 36mm filter for DSO imaging.

[somber stratus]

Granted.

[sour cradle]

only at around 850nm on most cams does the bayer stop

[flint siren]

610, 720, 850, CH4, 1010

[somber stratus]

You still pass the 850+ part of the spectrum though with the 685, so the SNR will still be better than an 850 longpass, despite the OSC cam.

[fathom oak]

so still probably better than ch4?

[somber stratus]

They're completely different use cases, so hard to compare.

[sour cradle]

I have 685, 850, 940(20nm wide), and 1000

[somber stratus]

CH4 is pretty niche

[fathom oak]

oh sorry lol I'm still trying to learn what all of this stuff does

[somber stratus]

685 can be used for all types of imaging. Luminance combination with RGB, Venus IR-UV bi-colour to name a few.

[fathom oak]

ok thanks for the help!

[somber stratus]

this is CH4 btw

[fathom oak]

I just think this looks so cool hahah

[sour cradle]

wait till u see saturn ch4

[flint siren]

yeah but remember it's a 1m heroic frog

[somber stratus]

presumably a 685 or some red filter on top here. CH4 bottom.

[flint siren]

CH4 suffers a lot from diffraction, especially with small apertures

[somber stratus]

Completely different aesthetic. Depends what you like

[fathom oak]

I'm at 8" currently

[sour cradle]

the one downside to infrared light... a shame really

[livid sierra]

Wth is 940/20nm for.

[flint siren]

i'm at 8" too

[somber stratus]

Imagine IR was both better for seeing and resolve.

[thick heron]

8" is fine for CH4.

[flint siren]

quite limited on saturn tbf

[sour cradle]

well
if the universe worked like that
imagine how good radio would be

[fathom oak]

I'll probably go for 685 I guess

[somber stratus]

true

[flint siren]

yeah 685 is the best option with similars 642

[sour cradle]

its for sulfur III
its mostly useless
but technically isnt

[fathom oak]

any good brands for this one or not really?

[somber stratus]

Player one, Baader

[flint siren]

as in a filter that differs from red but not too deep in NIR for res and SNR

[somber stratus]

yup, why I like my 642BP.

Cuts the 850+ part so improves res under not-shit seeing

and dispersion is reduced at 200nm bandwidth. Helps with ADC inaccuracies

[livid sierra]

How would 642BP compare against 610+uv/ir cut for 610-700nm bandpass?

[fathom oak]

hmm the player one 685 filter is much cheaper than baader. Any reason?

[sour cradle]

thats just called a red filter

[livid sierra]

Right woops.

[flint siren]

that's also called poor SNR

[somber stratus]

More SNR, and that's about it. Slightly different look too as it's slightly shifted to the longer wavelengths.

Technically the 642 would be lower res too but likely not noticeable

[sour cradle]

does jupiter and saturn have anything going on in the uva region?

[flint siren]

For a saturn with more opened rings maybe, right now it sucks a bit

[somber stratus]

yeah they look really cool, but the SNR is absolute dogshit since they're so far from the Sun, and Earth's atmosphere blocks a bunch of UV

[sour cradle]

well
you know how stupid i am thats not gonna discourage me im gonna go image them in uv now

[thick heron]

But the whole point of CH4 is for the cloudtops. Wide open rings block more of that.

[fathom oak]

Is there a reason the P1 685 filter is so much cheaper than the Baader one?

[flint siren]

But looks better

[somber stratus]

UV from last year with the 16" at native

[flint siren]

noisy ahh

[thick heron]

Which UV filter?

[somber stratus]

and year before that

Baader Bessel-U

[flint siren]

Jupiter looks way cooler than Sat lol

UV Jupiter deserve more love

[somber stratus]

shame the seeing is so bad too

[sour cradle]

well
at least you get less diffraction

[flint siren]

better but unsable resolving power

[sour cradle]

yeah
unless u move to space
always an option to move to space tho

[thick heron]

RIP Transmission.

[sour cradle]

is that better or worse than the U-venus?

[livid sierra]

I believe the signal is about the same as a 320-380nm filter because it passes some longer wavelengths.

You could argue Bessel-U is better.

[somber stratus]

yup, would've liked a chroma but they're rare

[thick heron]

Which U-Venus?

[livid sierra]

https://www.planetary-astronomy-and-imaging.com/en/best-filters-for-venus/ Article about it.

[thick heron]

There are multiple.

[sour cradle]

theres more than one type?
damn

[thick heron]

Who makes the U-Venus you're thinking of?

I know of two off the top of my head.

[sour cradle]

the baader one

[thick heron]

Apparently there are a lot more than two.

This is their U-Venus filter.

This is my Chroma U-Bessell.

[livid sierra]

It's just a general name companies use I think, P1 has one too.

[sour cradle]

ah yeah i can see why that one is the best

[fathom oak]

.

[sour cradle]

because player one is best

[fathom oak]

is there actually any difference between the filters?

because $70 less is a pretty nice deal

[sour cradle]

probably not much
i mean, the baader one might be tighter on the pass or a little higher transmission, but there shouldnt be much difference

[ruby compass]

Yo. Could someone like fix the brightness and stuf of my moon mosaic?

preview:

[fading plume]

You can. Use astrosurface for wavelets and make a preset.
Crop panels before stitching.

[low oar]

Should I remove my ir/uv cut filter when recording? and just go visible?

[low oar]

You have to do it by yourself to each panel

Looks like all you need is the second one from top

To be dimmer

[thick heron]

Either UV/IR cut to pass visible light or IR-pass to... well... pass IR light to the sensor. Without a filter, the sensor gets both, which will be more affected by seeing than either on their own.

[somber stratus]

not to mention dispersion

[somber stratus]

like Ethan says, unfiltered is unwise. Choose one or the other, VIS or NIR

[sterile marsh]

Tom what barlow do you suggest i buy

[ruby compass]

Celestron Xcel Lx 3x barlow

He would deff recomend the same one

If not than the 2x

[low oar]

So I have to get 2 separate ones? The filter I use is both uv and ir cut

[thick heron]

One UV/IR cut filter for visible light, one IR-pass filter for near-IR.

[main flume]

Hi

[main flume]

This is my best of Jupiter. Telescope stats: 130 mm aperture, 650 mm focal length, Barlow 2x and ASI662MC CCD camera.

Also Jupiter

This one is my last. I took it in march 2025 just 2 days before lunar eclipse. Idk why but it looks green unlike others, maybe cuz it wasn't late enough so it had enough scattering. Also you can see Io's shadow

[ruby compass]

Really good for 5"

[main flume]

Actually I was very surprised for my own results, since a 5 inch telescope isn't... well, not the best, you know, and most online reviews weren't as good as I expected. But it was my 1st telescope, so I still bought it. It resulted to be good enough. But I used just my phone, a 10 mm ocular and no barlow lens. This still good enough, at least to distinguish Saturn's rings. But in december I got my CCD and it was the best addition for my telescope. Also the Barlow lens came with the camera.

An addition I do need is a filter to avoid IR and UV

Those are for planetary

And for deep sky I need a filter to avoid light pollution

Any recommendations?

[woven kite]

Oh yar thats dope

[sterile marsh]

I finally learned how to get rid of luminance noise

[cursive inlet]

Venus uv/ir last morning

[cursive inlet]

Gonna try to get Mercury in daylight

[livid sierra]

Nice, good luck

[livid sierra]

Luminance noise?

[somber stratus]

Nuked timelapse from the 30th showing the rotation a little better. Ring spoke top right is more prominent here too.

[livid sierra]

I might have barely gotten that same spoke, still have to process it but I got some 850nm data at the same time. At the same time I doubt it because L resolution.

[sour cradle]

Interesting to actually be able to see the planet with enough detail to see its rotation

[sterile marsh]

Yeah

[livid sierra]

What do you mean?

[sterile marsh]

In photo shop there is a setting called luminance noise reduction and it transformed the image

[livid sierra]

So just noise reduction.

Might as well just use a bit of gaussian blur or despeckle.

Rhea transit on Saturn.

[fathom oak]

you can do the same thing in registax or astrosurface which are each good planetary processing software

[ruby compass]

get an 8" dob

[ruby compass]

thats called bluring the image

[low oar]

This morning

[sterile marsh]

I use all of that to but it didnt get rid of that

[main flume]

I was asking a filter to avoid IR or UV

[ruby compass]

oh

idk

ir is alot better tho

[livid sierra]

How is IR better.

[rugged knoll]

Svbony uvir cut

[livid sierra]

A UV/IR Cut.

[rugged knoll]

Cheap and works well

[livid sierra]

They're all cheap and I'd avoid Svbony personally.

It's probably fine but I'd rather get a filter from a more reliable company.

[main flume]

Thank u

[ruby compass]

ir is better than uv cuz its great for removing atmospheric wobble and uv is kinda hard to use

[main flume]

Yeah ik

[ruby compass]

oh. wait. he was asking to remove themm

[livid sierra]

Yeah but isn’t a UV/IR Cut a better filter to have if you only get one?

[ruby compass]

yeah than uv/ir cut

[ruby compass]

personally no. you can still shoot broadband without an uv/ir cut.
