Planetary Imaging

[quick cairn]

You are smart

[flint siren]

high dynamic range, means that faint and bright features are composited to appear at the same brightness

[quick cairn]

Gotcha, does that take photoshop or ?

[flint siren]

i do it with PS but you can do it with GIMP i'm sure

[quick cairn]

I don’t have ir720

I have ir 650 and ir850

[flint siren]

the rings is for experienced imagers though

[quick cairn]

Well, you start somewhere

I’m experienced with the bigger gas giants

[flint siren]

you'll see yourself, thing ain't easy

[quick cairn]

Definitely not

How many failed attempts in good seeing?

[flint siren]

more than 10

[quick cairn]

Respectable

What do you mean exactly by integrate, did you derotate at all?

[flint siren]

integration just means how many time you spent on the target

[quick cairn]

I knew that I was just verifying? So when you say integration with Uranus, for example you just mean the total amount of time you put into all the stacks together.

[flint siren]

can be derotation, stack of stacks or just pure integration

[flint siren]

Yeah

[quick cairn]

I have never tried stacking multiple stacks together. That is very interesting to me.

I mean, it’s definitely possible with my set up correct?

[flint siren]

it's only usefull for certain thingss

[flint siren]

What ? the rings ?

[quick cairn]

Yeah

[flint siren]

dunno, i've never used your scope

[quick cairn]

It’s a 10” goto skywatcher

Native 1200mm

F/5

[flint siren]

if you have too much glare then no

[quick cairn]

Like moonlight?

[flint siren]

Tom got the ring with a 16" SW Dob so i guess the SW dobs are able to do it

though the tracking is gonna limit you there

[quick cairn]

Yeah for sure

What scope do you have?

[flint siren]

no, some parts in your scope reflecting light from the target making a halo around the planet

[flint siren]

I use a C8 with a glare shielding

like i cover the shiny parts of the scope with some things to limit glare

[quick cairn]

That’s interesting can you give me an example?

[quick cairn]

Eq mount?

I’ve heard of some guiding for the ice giants, do you?

[flint siren]

yeah, i did guide when shooting the rings

it helps

[flint siren]

For example, the secondary holder of the older C8s is shiny af

So it put a cover around it so it doesn't affect my observations

[quick cairn]

That’s smart

I’ll look into that

[quick cairn]

Did you self teach imaging Uranus’s rings or what was your motivation?

[flint siren]

you just try, fail, learn from that fail and try again

a bit like everything lol

[quick cairn]

and you put an hour worth of 15 min stacks you said?

[flint siren]

nah, one time was two hours of integ, one was 15 mins

but it's barely visible in 15 mins

whereas it's clearly visible in two hours

[quick cairn]

so can tell me exactly what you did with the integration? im still a little confused

how long were the stacka and what percent, and then what perfect of those stacks did you stack

basically asking how many videos to take how long each, and what ir pass filters for them

[flint siren]

stacks are usually 3 mins, 90%.

And i already said for the filters.

[quick cairn]

this isnt rings right?

it that halo'ing you were talking about?

[flint siren]

That would be the airy disk

[quick cairn]

from glare?

How do you tell the difference

[flint siren]

no, from diffraction

[quick cairn]

ah,

could you maybe share with me your data so i can practice processing the final stack?

[flint siren]

yeah i'll send you a DM tomorrow

[quick cairn]

thanks

apprec it

old data im stacking higher percents

[somber stratus]

Some minor moon spotting.

[quick cairn]

thats dope

im clouded out atm

[shell epoch]

It's a lot cheaper to just mod a regular 8" dob mount and attach onstep to it

Or get a polar wedge for it

[shell epoch]

You should image proplyd's in the Orion Nebula for your next dso

[quick cairn]

This had to have resolved enke

[low oar]

Copernicus Tonight

[somber isle]

Crazy stuff

[quick cairn]

24" bad seeing

This is 3 minutes of data derotated

[ruby compass]

Woahh

[livid sierra]

If this is with a 24” then I feel sorry for that thing.

[thick heron]

Seeing signs of astigmatism that are giving me flashbacks.

[somber stratus]

lol

[quick cairn]

Haha yeah the seeing was bad

It was built in the 90’s it’s an F/5

[quick cairn]

Can you explain what you mean?

Tom if you wrote a guide to large mirrors with planetary imaging handbook I’d buy it

[livid sierra]

24” in a closed tube is an interesting choice I feel like.

Asking for tube currents.

[quick cairn]

Yeah it’s tough

It’s a visual scope but I managed to slap a camera on it

[somber stratus]

That mirror support looks questionable but hard to tell what's inside.

[quick cairn]

Yeah I’m not sure, it’s colimated well

I let it sit out for hours before using it to cool down

[quick cairn]

You said you got your 24” second hand? What site? And did you install the tracking or did they already have it

[somber stratus]

Just an astro buy/sell site in the UK. It's not like there's another one since it's a custom built scope.

[quick cairn]

Well you have really good equipment, quite special

[ruby compass]

is there any astro buy/sell for the rest of europe?

[somber stratus]

No idea.

[thick heron]

I see a directional blur. The best way to check is to see if the out of focus doughnut is elongated. It will rotate by 90 degrees if you switch from one side of focus the other.

[untold spear]

This with 3x Telecentric Svbony?

[elder venture]

varies country to country

i mean i recently saw a 14'' goto SW go for 850 here

the thing was in perfect condition

[low oar]

Yea how you know?

[untold spear]

Ig story

[rain mauve]

finally some reasonable seeing

[woven tundra]

Not with a phone right?

[rain mauve]

no.. im not using phone haha

[low oar]

Ahhh

[woven tundra]

Ok i got scared, nice image tho

[rain mauve]

hahaha why scared tho

[woven tundra]

That you took the phone to the next level

[rain mauve]

Oh damnn..

[elder venture]

What scope did you use?

[untold spear]

I finally found first person who use it for imaging

What Barlow did you use before?

[quick cairn]

insane

[quick cairn]

sorry going to blend for friend

[ruby compass]

@flint siren did u ever get surface detail on like io?

Cuz ganemeade i think u did

[somber stratus]

The bright equatorial region is relatively easy when Io is in transit, but other than that I doubt it with an 8".

[ruby compass]

Yeah

But Yoships is Yoships 😂

[quick cairn]

its always too bright for me

[ruby compass]

Io?

[quick cairn]

If i crank down gain and gamma and rise brightness you can see some detail but this was also in pretty bad seeing, ive gotten detail on the 24" though but thats different this is 10"

[silent mesa]

I’ve got slight detail before

[quick cairn]

Yeah transits are easier

[ruby compass]

24" tho

😭

[ruby compass]

What size?

[silent mesa]

8 inch

[ruby compass]

W bro

[quick cairn]

I got this

here is io in bad seeing with 10"

[ruby compass]

This is my latest jupiter. Its from this monday with bad seeing.

Ir ofc

[quick cairn]

8"

Im not sure which moon is bottom left but its bright asf

[quick cairn]

nir

[ruby compass]

Never understod. Does nir mean near ir as in close to ir or as in closest range of ir?

[quick cairn]

near infered

[ruby compass]

Its 685nm btw

[quick cairn]

yeah nir

[ruby compass]

?

[quick cairn]

near ir

[ruby compass]

So nir is near infrared as in closest range of ir?

[quick cairn]

n o

as in close to infered

but you can't get there with our cameras

I THINK

it may be that it breaks throught the air better, if we recorded in complete ir it would be dimmer because of way less signal

[ruby compass]

What nm is actually ir tho?

Also fun fact if you didnt know. At 1mm wavelenghts it doesnt matter if you shoot during the day or night

[quick cairn]

Interesting

[quick cairn]

not bad for 8"

[somber stratus]

Near Infrared is a subdivision of IR. There’s NIR aka short-wave IR, SWIR (700nm-2,500nm), Mid-wave IR (2.5 to 25 microns), and far IR which is 25 to 1000 microns ish but it’s on the border with Microwave at that point.

[quick cairn]

In planatary is there any use for over 900?

[somber stratus]

Yes, Venus nightside imaging.

[quick cairn]

I remember you doing those.

[somber stratus]

And technically Uranus ring imaging takes advantage of that band though admittedly with longpasses

[quick cairn]

I am going to try Uranus rings on a new moon and hope for good seeing, I know the methods and have the equipment but I’ll probably fail a lot

@flint siren would an 8” refractor with amazing tracking, super good clock drive, be better for Uranus rings than my 10” skywatcher that’s not nearly as good tracking?

It’s F/15 so I’d use an ADC and the filter and that’s all

Would be like 4500mm

Would be F/19.5

Finding it will be a nightmare but once I do shouldn’t have issues can star hop visual first

[ruby compass]

Yeah

Thanks

[ruby compass]

Europa most likley

[rain mauve]

DIY Hadley telescope, it has a 4.5 inch diameter of primary mirror

[quick cairn]

Terrible seeing tonight ):

[elder venture]

Oh right you’re the feller we showed the Hadley too, very lovely to see you getting this far already

[rain mauve]

Thank youu very much

[terse night]

There's Astrosell in Italy, they sometimes ship internationally

[flint siren]

Nope, you can only get the equatorial band during transits as Tom said.

Never got the chance to have a proper transit.

[flint siren]

f/15 is too much, so no not really.

unless you have insane tracking then yeah with good seeing you can just crank up the exposure time.

[quick cairn]

Don’t you use high F ratio?

[flint siren]

f/10 yeah

[quick cairn]

It’s that’s it)?

I swore you said you got at like F/27 or something

[flint siren]

but i feel like that's the limit for them rings

[quick cairn]

Gotcha

[flint siren]

for standard planetary

[quick cairn]

Where do you want the histogram for the rings?

[ruby compass]

Ah. Ganemeade tho?

[flint siren]

Yeah ganymede is easier

[flint siren]

Dunno i don't really look at the histogram

I usually go with the longer exposure the conditions can handle and adjust the gain so the planet is barely saturated

[rain mauve]

Does drizzle really help?

[quick cairn]

can yall give the data a go?

Im terrible at moon processing

jupiter and ganymede

last night, terrible seeing

[livid sierra]

That's not a raw stack.

[quick cairn]

i cropped, here

pixel size 2.9

[low oar]

Well I was only using it for tests, I used a cheap 2x Barlow before and I was testing the 3x they sent me because I won it in a contest they did

[livid sierra]

It's still not raw.

I can't do any processing if you already processed it.

[quick cairn]

I’m confused. It’s from winjupos

Like i saved it from winjupos

I’ll download again

[livid sierra]

A raw unsharpened stack is required to do some meaningful processing.

Your image is already sharpened and derotated now. What do you want people to do with it?

[quick cairn]

I see, i was under the impression you sharpen slightly before derotation and then process some after

here are the better of the night, i derotated 33 though

[livid sierra]

Doing that turned this moon into my pencil size 15 in PS.

[quick cairn]

I thought that looked okay, maybe ive been doing it all wrong?

do you process all of them individually before derotation? I batch sharpen

[livid sierra]

Not individually, batch sharpen. But the main sharpening is done before derotation, not afterwards.

[quick cairn]

what were the sharpen settings for this one?

[quick cairn]

Thanks for the advice, Duif.

[livid sierra]

No problem.

[quick cairn]

I just used them and dude, I have so much to learn its wayyyyy better than what I did.

[livid sierra]

I'll say your sharpening wasn't bad either. But generally it's bad practice to derotate non-sharpened, or very lightly sharpened stacks, to then do processing afterwards.

[ruby compass]

crazy

[ruby compass]

how far across is it in angular size? (ganemeade)

like in arc

[somber stratus]

Ganymede* and 1.7".

[ruby compass]

ah

yeah mb

[ruby compass]

okay so its 10 pixels across exactly for me.

thats quite good for a 8" right?

[ruby compass]

@somber stratus jupier rings when?

[quick cairn]

Never, he tried

I mean maybe if he gets a bigger scope but probably not

[ruby compass]

it should be possibloe tho with like 10h of data

[somber stratus]

not really

Even HST struggles immensely with long exposure CH4.

whereas it gets Uranian rings with ease, in all filters.

[sand umbra]

It’s easy to get Io’s detail and shading during Jupiter transit

[ruby compass]

Ah

[ruby compass]

Whats your best seeing ever in a video? Is it still the mars ir video?

Also bro you NEED to image the terapizium

[quick cairn]

He had some crazy Saturn once

That’s bad seeing for him but I think it’s pretty cool

[gray orchid]

It's been a dam minute since I've done some planets

winter seeing is on average pretty horid but ehh this was fun at least

I am now no longer untracked, and finally picked up a uranus C.

[quick cairn]

Awesome man

[graceful creek]

https://tenor.com/view/fun-ok-gif-23395164

[ruby compass]

Alot of turbulence but very sharp

[quick cairn]

was like 20 degrees yeah

[ruby compass]

This is the one im talking about

Dont ask how i found it

[ruby compass]

Nice

[ruby compass]

@quick cairn

[quick cairn]

his data

[ruby compass]

Ye

[quick cairn]

that is insane seeing good god

[ruby compass]

Think thats the best he has ever had

Atleast it was in may

[untold spear]

So how is the performance to you?

[rain mauve]

Can I get Uranus through 4.5 inch telescope?

[white prawn]

It was discovered with a 6" telescope. Was 7' long so F14. Can't speak for the level of detail but you'll probably see something.

[sand umbra]

It will appear as a star but if you process it you’ll know cuz of the color

[rain mauve]

Alright thanks for the information!

[elder venture]

I can see Uranus as a very small, light-blue dot through my 5“ so yeah

[olive saddle]

I saw it once with my StarBlast, which is a 4.5" newt

It appeared as a star, but after a quick phone image it was very noticeably blue, like much bluer than stars that are already noticeably blue.

no actual detail resolved ofc, but this is roughly what it looked like. I only spotted it because it was close to the Moon at the time, and I was using my night sky app to figure out where it was in relation to the Moon.

[ruby compass]

@somber stratus fire video https://www.youtube.com/watch?v=M4yghGKkY78

[ruby compass]

tried reprossesing some of your old data (gone wrong)

idk what i was on 😭

[main flume]

gammy knees

[rain mauve]

i see...

[rain mauve]

woahh very nice

[olive saddle]

it's really not lol

honestly the live view was more impressive

[rain mauve]

atleast u got something xD

i didnt spot any at all, since im manually tracking

[olive saddle]

even despite just being a tiny dot, was cool to know I was looking at Uranus

visual astronomy really is about appreciating the almost unseeable

[low oar]

Well I’ve used it once in ok seeing and I enjoyed the views pretty well

I’ll test more in the future under better seeing to push the limits on my scope

[rain mauve]

Yeahh, might be need to experience this once xD

I have no chance to see them XD, might need to precise point at them

[olive saddle]

well, yeah

that's how you look at literally anything in the night sky

A Telrad can help find things, if a basic finderscope or red dot sight are too difficult to use for some reason

[rain mauve]

Ahhh I see

Alright alright

Thanks tho

[sand umbra]

Yet to image, Hawaiian weather is super bad, but when it’s clear it’s super wobbly, when it’s not wobbly it’s not transparent

10” is waiting to collect light again, and I’m sure it’s more than ready

[keen ginkgo]

My first attempt at planetary using my DSLR attached to Skywatcher 200PDS. 3 minute video, stacked and processed using PIPP, Autostakkert, and Registax (also it was my first time using Registax)

(And 5x Barlow so effective focal length of 5000mm)

[rain mauve]

Very cool

[olive saddle]

pretty good for your first

[keen ginkgo]

I have to admit, the conditions were basically pristine

[rain mauve]

jupiter and europa transit, seeing were bad, high thin clouds were everywhere and kind of messed up my image xD

[rain mauve]

Anyway does derotation like really improving the quality of the image?

[graceful creek]

earth

[quick cairn]

Only for big aperture

[ruby compass]

Woah

What scope?

😭🙏🏻

[main flume]

how big is ur appature

like 50 meters?

how do you get high res shots like that

[rain mauve]

awesome!

[low oar]

Not the best but a nice io transit the other day

[quick cairn]

From that distance I like it

[low oar]

Thx

[elder venture]

It cleans it up

Though on small apertures the effect is negligible

[quick cairn]

Hey @thick heron I have the 715mc and the imx585. I understand the 585 is simply better but the pixels are also bigger so for the same sampling I need much more focal length, doesn’t that depend on seeing though? The 715 has half the sized pixels 1.45. So for the sampling I need half the focal length? But it’s more complicated than that because the 585 has a better sensor in general right? Can you clear this up for me

[quick cairn]

Or anyone with an understanding.

[low oar]

115 Megapixel Full Wolf Moon Mosaic At 99% Illuminated

[thick heron]

You need more focal length for the IMX585 to reach the same sampling of the IMX715. Seeing doesn't change anything about this relationship.

[graceful creek]

when will moon be 120%

[buoyant belfry]

drgs pobly

[quick cairn]

Single 30s stack

[quick cairn]

Gotcha. Last thing, if I’m getting 5-6k frames with 45 second videos, in good but variable seeing probably 20% of the video is above average. What percent do I stack? I would think 20% but at the same time that only stacks 1000 frames so what’s your advice?

[thick heron]

Experiment and find what works best for you. Probably don't ever go single digits, or very high unless the seeing is very consistent for the entire recording.

[flint siren]

Just use the IMX585C at ~f/20 and you'll be good.

[flint siren]

We said this already but you can do longer vids. At least 90s i'm pretty sure.

[flint siren]

You can maybe even reduce the fl if your seeing is not good enough.

[loud ledge]

Hello

I recently got a new camera, now i dont have any barlows yet but this is what jupiter appeared like in size

Would anyone know what barlow and what type of barlow id need to get (3x, 2x etc)

My telescopes fl is 650mm

[low oar]

I would try a 2x but the fl seems to be what is bringing it down, the fov is to wide

[ruby compass]

@flint siren are there any good reducers for my scope? (Skywatcher skyliner classic 200p dob)

[loud ledge]

So should i just buy a 2x?

[fading plume]

What camera and telescope?

[low oar]

Personally I would invest in a larger scope, idk what you want your images to look like though so it’s up to uou

[buoyant belfry]

3x

wait 2x andalso crop it

[woven kite]

3 occultations this year

(its gonna be cloudy all 3 days)

[flint siren]

No, newts have no reducer (except of CCs that reduce the fl a tad bit).

[thick heron]

Starizona Nexus has a 0.75x reduction.

[elder venture]

But it’d cost more than just a scope with less focal length

[terse night]

Go with the ASA one and you get 0.73x

[ruby compass]

So what do I do if I want a better F ratio?

[flint siren]

Wydm by better f ratio ?

i'm sure it's already enough at f/6 (?)

[terse night]

Get a faster mirror, correctors have a limit to how much they can reduce before ruining the image, and they get expensive quickly (The Nexus is like 600€; the ASA is out of production, but we are talking 1000€)

[ruby compass]

I dont want to buy a new mirror tho😭

[elder venture]

Buy a different scope

[low oar]

Last night

[elder venture]

Very neat

[low oar]

Thanks

Thoughts?

[elder venture]

Id say it’s very very very slightly oversaturated looking at the GRS

If through some photoshopping you could remove/desaturate the blue edge caused by derotation I wouldn’t have anything negative to say about it

Very nice work

Quick phone edit

[sharp ridge]

nICW

Nice

looks a lil soft

can i have da stack?

[somber stratus]

Osiris my beloved

[rain mauve]

Woah moon surface

[low oar]

Valid valid

@elder venture I already posted to insta, and I’m happy with the result, but that blue edges on the left and right are bugging me now haha

[main flume]

i made a 0.33x reducer (in a sim), was like 8 lenses and still barely fit the spots in the airy disk

[somber stratus]

Blue hue is real detail.

That shouldn't be removed

It's a haze near the equator that's prominent in UV and Blue.

[elder venture]

The blue edges is real detail?

Ive only seen it happen because of derotation

[somber stratus]

Yes, atmospheric haze. It’s very much visible in single stacks.

[elder venture]

well the more you know

i may have just done the planetary equivalent to scnr

[somber stratus]

Saturated single stack.

UV from the other day too.

[elder venture]

Damn

very interesting actually

thank you for this

[graceful creek]

oh damn epic

[low oar]

Thought so

[main flume]

o waw

[woven kite]

toms always cooking

[olive saddle]

I love that you just have the ability to say "oh yeah no, this detail is real, here's an incredible photo I took that not only proves it but also shows how beautiful it is"

like that's just such an awesome thing to be able to do, with your planetary imaging

[graceful creek]

also i feel like its almost same color as seen with eye

[buoyant belfry]

1 hour rotation of jupiet using a phone and a 6"nwet

[rain mauve]

Very cool

[flint siren]

As tom said, the blue of the edges is real, but blue at the center of the planet is not.

[woven kite]

this is not my image. is this average for sct optics? theres a ghosting effect around it and a lot of sct images ive seen has this "overlay". ive gotten a second hand 8se sct and havent tried it yet due to clouds. im a bit disappointed already

[ruby compass]

@somber stratus your actually not far off yhe VLT 😭

[sharp ridge]

The vlt one is probably not even sharpened

[livid sierra]

These aren’t even the same objects.

[flint siren]

Stupid glazing, again

[somber stratus]

It is Ganymede but diff waveband

[rugged knoll]

toms images are crazy but hes definitely far off the vlt

[ruby compass]

It is

[ruby compass]

I mean ofc. But remember the vlt can go up too 200meter mirror. And doesnt have atmospheric wobble

[rugged knoll]

ok but hes still far off from the vlt

that doesnt make his image better

[rugged knoll]

also where exactly did you get a 200 meter mirror from

[ruby compass]

The vlt can combine the 4 big scopes and the small 1 meter ones with interferometry to use it as an 200meter mirror

[rugged knoll]

thats not a 200 meter mirror

[ruby compass]

Mathemeticly it is

[livid sierra]

I see. Still a bad comparison though.

[ruby compass]

The vlt hasnt shot it in another wavelenght

[flint siren]

It's about right, the VLT interferometer can achieve a resolution comparable to the one you could obtain with a 130-200m mirror.

[livid sierra]

Like I said, bad comparison.

Get an image that’s also in VIS.

[flint siren]

The VLT usually shoots in far NIR, so that comparaison doesn't hold.

For ffs stop making these 'me vs hubble' ahh comparaisons

[ruby compass]

Its fun tho😿

[flint siren]

Maybe but it doesn't tell much

Pointless

Everything to glaze Tom these days

[olive saddle]

Tom's good, real good. But there comes a point where the complimenting does get a little over the top lol

[somber stratus]

Io from LBT

that's a fair comparison and it's understandably out of any amateur league.

[ancient kelp]

Wow that’s amazing

[white prawn]

The atmosphere moves aside for him and the planets pose for him. We're just acknowledging the favoritism

[olive saddle]

that's just so cool, that this can be done at all with a ground based telescope

[elder venture]

I am wondering

What if tom were to shot in SWIR?

Wouldnt seeing effect it much less?

[fading plume]

The resolution drop is quite substantial.

[somber isle]

@flint siren

[elder venture]

I mean it depends on which camera no?

the IMX993 has a really good res of i think around 1440p (?) and sensitivity up to 1800nm

[fading plume]

Yeah but the wavelength is longer

Resolution drops. The only way to gain it back is more aperture.

[elder venture]

I mean... 24'' of aperture

So I suppose it depends how limited the aperture is by seeing to conclude whether or not youll end up gaining anything

[fading plume]

Over like 680nm ish you lose quite a lot.

[flint siren]

?

[untold spear]

Man, just keep mewing instead of glazing Tom 🥀

[flint siren]

Or work on your processing instead

[rain mauve]

I though the telescope from lbt would like:"oh yeah, maybe it has like 40 inch or more max like 60 inch to resolve detail like that" But no, I was wrong, it ain't telescope, it's a canon

I wonder how did they colimate it?

[flint siren]

And then imagine doing this with 4+ scopes at the VLT.

[rain mauve]

This one? 💀

[flint siren]

yeah

[rain mauve]

This can resolve another solar system?

[flint siren]

these questions...

[rain mauve]

alright sorry

[flint siren]

individual units are used to image exoplanets

but the interferometer can resolve stars btw

[rain mauve]

I see...

[flint siren]

Antares for example

[rain mauve]

What is this? Betelgeuse?

[flint siren]

Antares......

[rain mauve]

Oh wait I didn't see the message, sorry

[flint siren]

T Leporis

[rain mauve]

Woah...

[flint siren]

Pi1 Gruis

[flint siren]

Betelgeuse with a single unit

[rain mauve]

Very interesting...

[rain mauve]

Why is it darker on the December one

The rotation?

[flint siren]

cloud passing infront of it

[rain mauve]

Ohh....

I heard they use adaptive optics?

The vlt one, to get a better images

[flint siren]

Like almost every "large" professional telescope.

[rain mauve]

I see...

That answers my question, thanks anyway

[brazen moth]

Hi all! I made major updates to https://eise.app, a web based planetary image stacker, in the past few days. Biggest changes:

• Allows loading huge SER files
• Allows loading huge non-compressed AVI files
• Allows loading multiple files for stacking (like TIFs)
• Major improvements to post processing tools, added deconv sharpening
• Allows downloading a cropped and centered SER file, to replace PIPP maybe?

Let me know what you think, and if you run into issues let me know. If we all agree it's stable I would love to have some offiial "video reviews" from astro nerdfluencers, but not sure if people like it enough :).

[rugged knoll]

wow i havent heard from you in a long time

what happened

[rain mauve]

Very cool

[rain mauve]

It's there a limit? For uploading huge files?

[teal sandal]

what is the point of a web based stacker? Who is it for?

[low oar]

People without windows

[rain mauve]

People that doesn't have laptop, or pc, just phone and want to do Planetary stacking

[low oar]

A phone is crazy

[teal sandal]

Oh okay, makes sense now

[livid sierra]

I have yet to see a phone that can record SER videos.

[main flume]

you dont need windows for stacking

[low oar]

Well I know but it’s still the most popular

[silent mesa]

@livid sierra how do you colorize Jupiter in your images

[low oar]

?

What question is this?

I’m confused

[silent mesa]

Mb

It’s just I’m wondering how you get Jupiter so vibrant

[low oar]

What do yours look like

[silent mesa]

I feel like there is a big difference between how our images are colored. Mine looks a lot less saturated. I’m wondering how you do it

[low oar]

Like this?

[silent mesa]

Yeah

[rain mauve]

No phone can do that type of format... Sadly...

[livid sierra]

Increase saturation.

[silent mesa]

What program

[livid sierra]

Any image manipulation program.

GIMP, PS, AstroSurface, Affinity, Krita, just to name a few.

[low oar]

Increase exposure and carefully adjust the saturation and color sliders

[silent mesa]

In this case should I use smth like GIMP

[silent mesa]

What do you use

[brazen moth]

Yes exactly! Nothing works on my macbook.

[brazen moth]

Haha, I'm mainly a winter astro-nerd :).

[brazen moth]

There should not be a limit

[rugged knoll]

impossible for me lol

one clear night since September so far

[brazen moth]

Wow

Regarding developing Eise. The generative AI code assistants got so good, that adding new algorithms and easier file support is super easy to implement.

[low oar]

I just use Photoshop but yea that’s a close second

[brazen moth]

Here is it with more saturation and vibrance (using eise.app)

I might've overdone it a bit 🙂

[silent mesa]

It looks good though

I like it ❤️

[brazen moth]

I just dragged the Vibrance and Saturation sliders. And yes, great shot! what gear and how many frames did you have?

[sand umbra]

Gotta stop falling asleep I missed a good Galilean moon alignment with Jupiter, Callisto, Io, and Ganymede with the GRS but I fell asleep 2 hours before

[elder venture]

@somber stratus
I have a question.
Does it ever get boring to you? Planetary imaging?
Youve been at it a while, pumping out the best images but doesnt it get boring over time, when the room for improvement goes to essentially nil?

[brazen moth]

Well, you can always capture a meteorite or asteroid impacting jupiter right? :-D.

[teal sandal]

and there are countless small DSO's

for example seeing Hoag's object in Tom's 24" scope would be quite interesting actually

[brazen moth]

It's ridiculous how fast you can "code" with AI these days. Now Eise has a frame quality threshold checker thing!

[main flume]

evil vibe coder

:(

[brazen moth]

I could do it myself, but everything that I've built in the past week would've taken me full time for a year.

[marsh elbow]

Yeah its good and bad, it can help you alot but you wont learn anything from just putting prompts to gpt and letting it do all the work. People's work should be appreciated more!!

[brazen moth]

I am learning though! About algorithms, how to implement them. But indeed, I'm not core diving into it. And even then you have those things off the shelf as well of course. It's as if I install a tonload of dependencies that are generated for me on the fly.

[low oar]

Does Apple stop making iPhones?

[marsh elbow]

Nice! I was once interested in learning coding in python and lua but i just lost motivation, mainly because of ai because i would be afraid ai would dominate coding and plus coding wasnt that fun. Spending 1 hour coding something simple aint fun.

[sand umbra]

Things are never fixed, his equipment may stay the same but soon enough he’ll get something else to test out and possibly bring more detail out. And with the planets, they are constantly changing. Ex: Jupiters cloud belts, storms, and its perspective on earth/subtle tilt. For Saturn sometimes we get intel about things that are visible with our equipment like Saturns band disruption. Mars comes once in a while, and there’s still a lot to go through.

TL;DR - things are never the same, new opportunities to catch

[elder venture]

Oh im well aware

But doing the same thing over and over will become boring at some point

Until there’s something new like new gear

[brazen moth]

Know that there are people out there that like to log things, and that data sometimes ends up being very valuable in the future. Like this Dutch guy who counted bees from one single spot every day (or week or month). Or this other Dutch professor (Kees de Jager) who every day logged the rotation speed of the earth by tracking one single star every 24 hours and writing down the timing of it passing the Meredian. Nothing changes in the task at hand, it doesn't get more spectacular over time, but people see the importance or just like it :).

[livid sierra]

Indeed. Imaging is not merely about constantly needing to do new things. Keeping track of the planets through the time is a very large part of it.

[rain mauve]

yesterday jupiter opposition, not great seeing

[main flume]

smol 🤏

[rain mauve]

Yeah this is through 4.5 inch with 1800 fl, svbony305 pro

[main flume]

impressive!

[rain mauve]

Thanks

[winter moat]

Here Jupiter with mine 4.3 Inch CCT

[rain mauve]

Nice!

[main flume]

jup

[rain mauve]

i have mine with ok seeing!

[winter moat]

Niice

which scope do you have

[rain mauve]

It's DIY Hadley telescope

[quick cairn]

I got cloud cover and stopped or else would have imaged the entire thing

[quick cairn]

My work lately with the 10”

[brazen moth]

Could anyone try to stack and process the above Jupiter's with Eise.app? Would help be a bunch fixing bugs!

(Or I would like to have the source data so I can try it myself)

[main flume]

the shadow has a shadow

[quick cairn]

Lol winjupos is hard to master

I’m getting better though

[quick cairn]

Sharing huge SER or AVI files to you would take hours, I’ll test them myself when I get off work with very good (easy to work with) data

[quick cairn]

May I ask, does the app need perfect tracking? Or can it manager frames at different ROI’s? Also what’s the code doing to decide the quality of a frame?

[brazen moth]

No the object is allowed to jump around, you can recenter manually during the vid. It will auto crop and center it etc.

[quick cairn]

I like what you are doing btw

Stacking on phones is needed imo for beginners that don’t have laptops

Especially kids

[brazen moth]

I actually don't know how well it works on phones. Especially if the file you select requires ffmpeg in the browser (it works but is slow). "simple AVI" files or SER files are parsed with custom optimized code that works pretty smooth.

[sharp ridge]

Ill give it a try

Hmm

[brazen moth]

Meh! Perhaps we can DM to get it fixed?

[quick cairn]

That’s one hell of a reference frame

[brazen moth]

I think this is an out of memory issue. If you provide a max frames or "just stack the best 30%" it will use less memory. Curious how big your vid file was?

[quick cairn]

My single videos are often between 6-10gb for 60 seconds

That’s not much **to us **

But I’m not sure about smalller scopes might work better

[sharp ridge]

Im trying a different file with just auto 30% and it seems fine for now

[brazen moth]

This is one of my processed stacks. My frames are way smaller so less data, haha.

[quick cairn]

Right

[winter moat]

Here is my best picture of Jupiter, finished a few hours ago

[brazen moth]

nice! Did it reach the end and post processing screen?

[sharp ridge]

Its still stacking

Ok it stacked

[quick cairn]

What size scope?

[winter moat]

114mm Aperture

https://www.astroshop.eu/telescopes/omegon-cassegrain-telescope-pro-cc-114-1368-ota/p,80953

[quick cairn]

Very good for size

Exceptional even

[winter moat]

I had very good seeing

[sharp ridge]

This weird pattern isnt normal tho

[brazen moth]

I sometimes get that when I overdo wavelets? Or is this without doing that?

[sharp ridge]

Its wavelets but shows up at any setting

[brazen moth]

Odd. So do use wavelets in other tools as well and then you don't see it?

You can get the unprocessed png to test somewhere else

[quick cairn]

What kind of file is the final image?

It it’s Jpeg it’s simply too compressed

Sharpening doesn’t work the same

[brazen moth]

no it's PNG lossless

[quick cairn]

Damn.

Does the stacking convert whatever file you input into a PNG or JPEG before a stack?

The file type of the final is only dependent if the rest of the files are unchanged

[brazen moth]

I don't think so. checking

[quick cairn]

Alright

[brazen moth]

I chose PNG as export file type because that's the only native image format that provides no compression. ( I think, it's a decision from a while bac)

[quick cairn]

PNG compresses iir but a lot less

Than jpeg or meg or anything like that

@sharp ridge take an AS4 fresh stack and convert it straight into a PNG and see if you get the same affect? When using wavelets

I would but I’m at work

[brazen moth]

Yes but PNG can compress without "optimizing" the image and losing detail

[quick cairn]

I think how it works is PNG can be used to view the raw image but if you try to post process a png it starts being weird

(Could be wrong)

[brazen moth]

You view the raw stacked data on a 8 bit canvas. The png download button just turns that data into a PNG. In the stacking process nothing is turned into a PNG

[quick cairn]

You can download Tiff files onto your phone you just can’t view them, perhaps make another part of the website that can open them and process them in the app then turn into a png?

[sharp ridge]

Yeah its the png

[quick cairn]

Or have some wavelet options straight out of stacking

[sharp ridge]

First one is sharpened with astrosurface wavelet

Second one is through the app

[quick cairn]

Maybe this if you made the stack a tiff file instead of png and have a preview image in the state of a png? Thats a little complex but I don’t know another way

[brazen moth]

Thanks wow!

[quick cairn]

If you made the preview image a png converted by the current wavelet you apply on the tiff you never have to view the tiff

Because png can look the same as tiff before wavelets but in this case you’ll never apply the wavelets to the png

Only to the tiff

That’s previewed as a png

Not sure if that’s how it works

Just a thought

[sharp ridge]

Same settings in as4

Same wavelet

[brazen moth]

I learned it's called Moiré, it's not jpeg artefacts but because of doing debayering and demoisaicing in the wrong order. Building a fix I hope.

[quick cairn]

Awesome work

Keep it up

[brazen moth]

Thanks Ken for debugging! And also Thanks Jack for you cheering 😄

[sharp ridge]

Perhaps you can do the auto 30% but allow us to change the % before the analysis as many of us just use a stock % depending on liveview

[brazen moth]

Cool, will do. How do you decide the stock percentage in those nights?

[sharp ridge]

Guess lol

Like just have a text box there for us to type in the % beforehand

Another error

[brazen moth]

In my opinion this is an error it should ignore and just continue, but meh. thanks!

Oh wait, it says too many errors, my code didn't like it anymore

[quick cairn]

Hahaha

[brazen moth]

I haven't been able to fix the moiré yet. 💤 see ya

[quick cairn]

If it’s due to the png file you might want to consider what I said

[quick cairn]

The script would run it in this order:

Stack as a TIFF file,
Finish stacking,
Show image preview as a png conversion,
Allow wavelets to be applied then click apply and image preview reloads with the new wavelets.

You never need to view the tiff or download it, and you ignore the PNG compression issue when applying wavelets because the only thing the PNG does is give a preview image of the tiff file. The tiff file is what’s being given the wavelets.

It’s the same idea as AS4 with the preview but it’s slower

[brazen moth]

Btw, when I take Ken's Jupiter stack, and I put it in Eise for postprocessing, I don't get those moise artefacts. So the issue is at least not because of how the image is loaded into the post processor or displayed in the browser. Diving into it still!

[rain mauve]

today's jupiter

seeing was ok, but high cloud trespassing, making my vids a lot darker and detail wasnt in there

[quick cairn]

Nice bro

[brazen moth]

Hey Ken, would you be able to shrink down this SER to 20 frames or something and then upload it somewhere?

[cloud copper]

what are you using for processing?

[sharp ridge]

https://drive.google.com/file/d/13CINowgEaLBjOBiThFlsUa2snYUYdUPL/view?usp=sharing

Here i did 500 frames of best quality

[sharp ridge]

?

For that photo the Elise app

[cloud copper]

Never heard of it, is it good?

[brazen moth]

Woah thanks so much!!!

[brazen moth]

I think it started taking data from the SER file halfway the first frame?

[sharp ridge]

Hmm

So the first frame is bad?

[brazen moth]

I don't know exactly. I can also make a tool (tomorrow) in Eise to trim and export SER files.

[sand umbra]

Another hacker with the seeing

[brazen moth]

@sharp ridge Hey there! https://eise.app now has a Tools section, where you can select a SER file and trim the frames.

[rain mauve]

excellent seeing but, thin clouds disturbs my image session alot and wind also

[quick cairn]

holy single stack

[quick cairn]

single

[quick cairn]

All single stacks

[low oar]

Good seeing

[quick cairn]

Indeed

[sharp ridge]

Not bad eh

Reminds me of this image I took before

[quick cairn]

Thanks, this is 25 derotated ill work on more later have school

some of my best data

with a 10"

[sharp ridge]

Noice

[quick cairn]

Thanks

I have like 70 more stacks

[sharp ridge]

Perhaps try wavelet decomposition?

[quick cairn]

but you cant derotate all 70 so ill figure it out

[sharp ridge]

Idk if its beneficial to 10" scope tho

[quick cairn]

derotation?

[quick cairn]

im not sure what the decomposition part means

[sharp ridge]

Its a new(ish) technique for combining ir and color data when the seeing isn't the greatest

[quick cairn]

ohhh

[sharp ridge]

Keeps the sharpness of Ir data while maintaining color balance

[quick cairn]

See i took 5 ir and 20 raw and put them into winjupos... does it ignore the ir?

[quick cairn]

wow

How do you do it?

[sharp ridge]

Uh you do it separately I think

[quick cairn]

I had no idea

[sharp ridge]

I can send the link to the tutorial

[quick cairn]

thanks please do

[sharp ridge]

Its lil more complicated

And you use gimp

[quick cairn]

i have that yeah

[sharp ridge]

https://www.cloudynights.com/forums/topic/988913-nir-on-colour-wavelet-compositing-for-better-detail-with-proper-colour-in-poorer-seeing/#comment-14473797

[quick cairn]

okay.. for a 10" this is pretty good right?

[low oar]

Yea good seeing

I got the same data lol

I’m gonna process more when i get home

[quick cairn]

it was decent

some good and bad momets

i took 105 60 second stacks lmaooo

[low oar]

Jeeze

I didn’t get that much

I got tired

[quick cairn]

haha me too

and cold

the shadow after was too tempting

but i had to stop becasuse it went behind my house

[low oar]

Aw rip

[quick cairn]

I need to learn firecaptyre

i use sharp

[low oar]

My collation could have been better I think

It’s really easy

[quick cairn]

i stopped maybe 20 mins after this

[low oar]

Clean

[quick cairn]

single stack yeah seeing was getting worse too\

but it was also getting lower

[flint siren]

Not enough integ

[quick cairn]

scroll up

[flint siren]

Yeah for both

[low oar]

They are good images

[quick cairn]

More integration?

[flint siren]

Yeah

[quick cairn]

Well good thing I have 70 more stacks… that was 25

[flint siren]

I do ~25 of 2 mins usually.

[quick cairn]

Yeah that was 25 60 seconds

[quick cairn]

This

[sharp ridge]

I think you still haven't hit your scopes limit yet

[quick cairn]

Hell yeah

Good to hear

This is probably my best so far

Does it beat this? Ken?

[sharp ridge]

You sharpened it more, looks about similar?

With better seeing you can sharpen with less radius

Maybe smth like this

You can generally tell if you maxed out the scope if the details when you sharpen have kinda a granular look

Esp if you use deconvolution

[low oar]

Before opposition

I need to get a ir filter fr

Push my scope better

[low oar]

Isn’t 2 min to long?

[flint siren]

no ?

[low oar]

Alr

To each is their own

[sharp ridge]

I believe people have tested it to work for 5mins

Even with 16" scopes

Not ideal but autostakkert does do the job

I lost the thread but yes it should be fine

[low oar]

Interesting

I guess I just break it up for animation purposes

[quick cairn]

I’ll start doing two minutes again, then better SNR

[sharp ridge]

What were you using

Id say for you 3mins

If you want animation just interpolate

[quick cairn]

Are use 60 seconds.

I use

That was Christopher goes advice, but I don’t know

[sharp ridge]

He uses mono

And he has imaged from the 2000s

When tbe software wasn't that good

[quick cairn]

I see

[sharp ridge]

Nowadays you can do mono for 2 3mins and then derotate the mono channels seperately

[quick cairn]

Should yoships also use 3 mins? He hasn’t 8 inch.

[quick cairn]

I see

[sharp ridge]

I mean its up to preference

[quick cairn]

I see

[sharp ridge]

Tom does 75 secs

[quick cairn]

For 60 seconds I’m getting around 6000 frames per stack

[quick cairn]

Yeah

[sharp ridge]

It doesn't make difference

[quick cairn]

So I ended up having about 2000 images in the stack

[sharp ridge]

But if you want better stacks then longer is better

If you derotate then in the end its the same

[quick cairn]

I see

In theory it should be yeah

[sharp ridge]

Toms file sizes are absurd so 75secs is mainly for that I think

Its like 3-5gb for 75secs

Goofy

That's at 10500mm but now he change to 8100mm

[quick cairn]

Yeah, mine are roughly 6 to 8 GB for 60 seconds

[sharp ridge]

Do you use cutout

[quick cairn]

Like ROI? Of course.

[sharp ridge]

No, cutout

The scissors

[quick cairn]

No sure what you mean then

I processed completely on a PS4, Astro surface, and winjupos

[sharp ridge]

For example

The whole screen is the roi

But the yellow box is the scissors

So im only capturing the yellow box

[quick cairn]

I set my ROI to the size of the yellow box in that video

[sharp ridge]

Lol

Tracking must be pain then

[quick cairn]

Lol I use sharpcap pro

[quick cairn]

Not so much

[sharp ridge]

Rip then

[quick cairn]

I use planetary stabilization and censoring on the ROI so it really does not move at all

Centering*

[sharp ridge]

Ok

[quick cairn]

Very, very still

[sharp ridge]

I do feel that 6-8 gb per min is a lot tho

Are you doing 16 bit

[quick cairn]

Yes

[sharp ridge]

No wonder

[quick cairn]

Raw16

[sharp ridge]

Use 8 bit

No need 16

[quick cairn]

Really?

[sharp ridge]

Yes

[quick cairn]

That’s nice to know

Haha

[sharp ridge]

Unless you going for faint stuff like Uranus rings, Venus nightside or like some faint saturn moons smh you dont need 16 bit

[quick cairn]

Thanks for the info

[quick cairn]

What’s your exposure on this?

I use 10ms

Usually around 370 gain

Or is the seeing just great

[sharp ridge]

11 ms and like 330 gain

Tbf that was f15

Normally it would be 380 gain

Tom uses 12ms iirc

Im like his apprentice now

[low oar]

I use like 8-12 depending on the night

[quick cairn]

I run at F/19.5. and use 10ms

[quick cairn]

That live of you looked so clear, does fire capture let you adjust the gamma on the preview?

[sharp ridge]

Yes

[quick cairn]

I see

[quick cairn]

Let me show my live view from last night

[sharp ridge]

I do make goofy sounds in good seeing

[quick cairn]

Oh me too… last night I was going Hehehehehehehehe

Your voice…. I likey

[low oar]

Transit last night

[quick cairn]

Single stack I need to process the rest and derotate I’m just lazy hah

[rain mauve]

1 hour Jupiter rotation

[quick cairn]

Awesome

[dusty needle]

Hi, do u think i can do smth witha 60/900mm refractor (from Ziel) a 6mm 68 degrees svbony eyepiece and s25 camera?

[low oar]

the best gear to use is the gear you have

[dusty needle]

That's right but I mean what's the best I can do

[low oar]

not sure, you tell us, your probably the only person with that setup

[dusty needle]

okok

[low oar]

whats your best pics so far

@dusty needle

[brazen moth]

Working on adding some kind of comparison video export to https://eise.app. Good for social media!

[low oar]

that seeing is rough

[low oar]

im testing it right now

i meant to the other day but i have some time

[dusty needle]

i can't post pictures i don't know why

[low oar]

you need a differnet roll

different

[dusty needle]

roll?

[low oar]

role

[brazen moth]

Haha yeah it's some recent capture of me. I'm not that skilled yet :D. I find focussing difficult while having a laptop outside. When turning the knobs it wobbles, and then what, is it in focus? I don't know..

[low oar]

😢

[dusty needle]

oh okay

[low oar]

i usually focus on moons

[brazen moth]

Yeah those were also wobbly and very dim.

Waiting for clear nights and then let's goo!

I also added processing on the GPU as an experimental feature, it's way more super faster.

[low oar]

im doing that rn yea

i like the concept

but definitely needs some work 👍

[brazen moth]

Any idea what went wrong here you think? Could you share your data? Seems like the incorrect bayer profile?

[sharp ridge]

Did you add the function to cut the video

I was thinking

[low oar]

naw i did it right im sure

i just turned down the saturation

[sharp ridge]

One of the drawbacks of autostakkert is you cant cut out bad sections of video when for example the planet drifts out of frame or half cut out

[low oar]

cuz there is no auto balance

[low oar]

there is a reject frames with straight line artifacts setting

[brazen moth]

Oh, Eise just skips frames that have a half planet.

[sharp ridge]

You have to use space bar for every frame, being able to deselect the frames would be handy

[sharp ridge]

It doesn't work lol

[low oar]

yea

lol

didnt know if it was just me

[sharp ridge]

Then you get artifacts which sucks

So you have to use space bar 1000 times

[brazen moth]

So autostakkert doesn't skip frames with cut off planets?

[sharp ridge]

It should, but doesn't always get it right

[low oar]

naw

for some people thats a really importsant feature to have

[sharp ridge]

Its not much of a problem now but it might be nice for you to have the ability to select chunks of a video to stack say 0-3250, 3500-7000, and 7200-7500

You can only do one chunk in autostakkert

[low oar]

yea

[quick cairn]

I sit there removing frames it takes agessss

[quick cairn]

Who made AS4?

Why can’t he make it a hold space + drag

He could update it

[livid sierra]

AS!4 is not being worked on very actively because as far as I’m aware the author is busy doing things with NASA or ESA I believe.

[livid sierra]

Also his name is literally in the title bar of the software when you open it.

[quick cairn]

That’s fantastic

[quick cairn]

Yeah I knew that but I don’t have my laptop on me atm

[flint siren]

It does

[sharp ridge]

Well it certainly doesnt for me

[quick cairn]

Me neither

[low oar]

yeaa same here

[flint siren]

Try to use the stacks for animations

WJ's artefacts are just too obvious

[quick cairn]

How do I combat field rotation?

[flint siren]

Field rotation scripts

[quick cairn]

I have that from tom but completely forgot how to use it

[flint siren]

he explained it in this thread for someone

[quick cairn]

Alright

not bad

[flint siren]

The convo starts here, just see what's posted below. Tom explains everything you need to know IIRC.

[quick cairn]

oh sick

[flint siren]

You should also correct for that slight dispersion

[quick cairn]

dispersion?

like shaking?

[flint siren]

Stop reposting that thing

[quick cairn]

i keep changing it lol

[flint siren]

No atmospheric dispersion. I know you used an ADC but there is some slight disp left. You can see it on the oval storms in the south.

It looks (it's not) like missaligned channels.

[quick cairn]

i see

so rbg align?

[flint siren]

Maybe run the field rotation script before

Because if you run it on the stacks themselves, the field rotation will cause some issues

[quick cairn]

I see

[woven kite]

900mm focal length lol

you could get closer cause ur lens have different magnifications

apsc sensor cropping area is minuscule

900mm iss

[quick cairn]

80mm 150$ refractor 900 focal length

[quick cairn]

Did you track or did you hand track with guide scope?

[dusty needle]

That is crazy, i'll wait until my 6mm eyepiece arrive and then try to shoot some photos

[dusty needle]

what magnification? and what aperture?

[dusty needle]

how did you found it and track it so well?

[quick cairn]

900mm is the magnification

[quick cairn]

I hand tracked everything for my photo

[quick cairn]

This one

Just takes patience

[woven kite]

???😲

[quick cairn]

hey @somber stratus Im entering an in real life print out only planetary comp, trying to decide which image to do, Ive been told to turn gamma to 1.2-3 because print outs are different than pixels, whats your advice?

im not the best at processing these are all derotated

im also trying to decide if less noise is better or more noise better detail

[flint siren]

Could do a lil more processing

[quick cairn]

the issue is

if i wavelet or sharpen anymore

the moon gets an outside edge

[flint siren]

You need to learn to mask for that

We don't use the WJ derotation alone in our final images

I dont know how to

[flint siren]

Because it has artefacts, you need to manually clean them

We all use Photoshop

i dont know how to mask
