Planetary Imaging

[somber isle]

Tom is very popular today

[fathom oak]

poor guy lol

[thick heron]

Time to make a GUI for the script.

[lyric dome]

this is my FOV for the moon, i wanna photograph rn but everything is wet, and would take too long to setup, sad but there is always next time

[main flume]

waow

[lyric dome]

Great!

[lyric dome]

Epic

[low tendon]

what part of the moon is that

[ruby compass]

uhh

[fading plume]

plato i think

[main flume]

relatable

[somber stratus]

@lyric dome before/after field derotation script

Data from tonight

[lyric dome]

That’s amazing man!

Am I not sharpening Jupiter enough?

[somber stratus]

Depends entirely on how good seeing was. Looks poor here tbh

sharpen just enough before it becomes too noisy

[lyric dome]

Granted was with a 3 inch lol

Got it

[somber stratus]

yeah that too

[lyric dome]

So it yours noisy or does it look pixilated but just enough to where it doesn’t look bad?

In your mars

[somber stratus]

I purposely sharpened a little more (or rather, denoised less) on mine as I planned to derotate it. WJ derotation "stacks the stacks" per se, so the SNR is improved.

Single stack vs derotation of all those frames

[lyric dome]

Ohhhh I see

That’s insane bro

[somber stratus]

walking noise? where

i see none

Maybe a touch of motion blur from derotation. I think I had the outline a touch too large.

This was like 4% of 24 mins

This was just the output from WJ. Processing now. Should be able to pull a little more out of it hopefully

[main flume]

blurx

[lyric dome]

Hey @somber stratus hey man sorry to ping got a question, do you have any animations of Jupiter with 3 or more moons?

Like I have this, I didn’t film very long cuz the park closed but I think the 3 moons look so sick

[teal sandal]

@lyric dome have u got your 6 inch scope already?

[lyric dome]

Yes I got it 2 days ago, I still haven’t collimated it yet though

I’ve never collimated before it’s very hard haha

Not knowing what I’m doing, those Jupiter are from my 3 inch

[teal sandal]

cant wait for ur pics with a 6 inch

Im currently saving up for a 10 inch or more

do yall think i should save up a 1000 dorrar and buy myself a 10 incher or should I save up more for a 14-16 inch (this would take a lot)

[lyric dome]

I don’t know tbh

I got impatient I was gonna buy an 8-10 inch

However I had a 3 inch a shitty one

So I was in a worse place than you

[teal sandal]

yeah

ill get my 1000 and look up for some used deals

if ill be able t find a 12 or a 14 inch for that price

would be insane

and ill diy a goto system

[lyric dome]

Fr

You can DYI 😭😭

Crazyyy

[teal sandal]

tried something creative

[teal sandal]

yesss

[main flume]

red beanus

[teal sandal]

Beans

[main flume]

my moon image is having a seizure trying to stack xD

its made some ugly looks

[lyric dome]

Damn haha our Saturns aren’t much different

[teal sandal]

Yeah didn’t get a chance to get a proper Saturn image for my aperture

It was low at the horizon for me

[main flume]

if anyone wants it xD

[dark cargo]

Is that the same filter as whats used for the Venus nightside thermal emissions?

[ruby compass]

@somber stratus im an actuall idiot. It looks like the reason my "ir" filter had those blueleaks is bc i think I was using my duoband filter😭🙏🏻

[main flume]

HOW DO YOU GET THEM MIXED

NO FKIN WONDER

[ruby compass]

Thay look the same😭🙏🏻

(My filters)

[main flume]

HOWWW

SURELY YOU CANT SEE THROUGH THE IR FILTER

[ruby compass]

Cuz i have the sv183 and the sv220?

[main flume]

AND SURELY THEY HAVE LABELING

[main flume]

im mildly worked up from terraria master mode ^~^

[ruby compass]

Also tea

Look 😄

My ngc2276 image

[main flume]

well done

good imag

[ruby compass]

Im gonna get more data n8w

[main flume]

yeasss

with the duoband filter?

[ruby compass]

Both eithout and with

I dont think ill get any IR tho

[main flume]

ir is quite a challenge

[main flume]

im waiting for a tracking mount before i try dark dso in ir

so a year or so

[main flume]

same image or edited to be closer?

D:

the treachery

[candid flare]

at this stage toms gonna release a planetary processing tutorial for $60

[somber isle]

They harrasing bro 😭

[lyric dome]

@somber stratus I’ll pay for it

[fathom oak]

lowkey worth it

[main flume]

its a thing!!!

[waxen solstice]

Yes!!!!!!

[digital steppe]

get the 14 inch, the aperture is always worth it

[thick heron]

If you're just starting out or have a small telescope, I think jumping straight to a large telescope like a 14" can be risky. The inertia of a large telescope translates into a larger mental inertia of wanting to take it outside.

[white prawn]

On the one hand, I went from 70mm el-cheapo frac to 8" Newtonian on EQ and have been very happy and satisfied w/ results.

On the other hand I would love to get my hands on a 16".

On the other hand that's an observatory size and I don't have an observatory ATM so 8-10" will be good for that purpose.

On the other hand if you do have an observatory then might as well get the chonker in.

On the other hand ... that's it I'm running out of hands.

[lyric dome]

first ever attempt on my new scope, tell me do yall think I need better collimation? I have no idea how to collimate.

[somber isle]

Better collimation maybe. How was your seeing?

[lyric dome]

that was a 2min capture

[lyric dome]

honestly seeing was terrible

this was a 3min i didnt wanna make it look crazy with waveletrs

[somber isle]

If you get a longer video and have better seeing you will probably get some crazy results

[lyric dome]

cant do longer

planatary rotation caps out for jupiter in 3 mins

[somber isle]

Oh I see

Better seeing and a more precise collimation will probably do the trick then

[lyric dome]

Yes

[lyric dome]

2 moons

Io and eroupa

this is probably overprocessed jupiter with zero gain and 9ms exposure

[white prawn]

Not bad, yeah slightly overprocessed, and I won't judge. If it weren't for my over processing mistakes I wouldn't have been processing so it works out.

[lyric dome]

yeah

thanks

I like this tbh

[white prawn]

Little wobbly. Bugs the heck out of me that the atmosphere can't be perfectly still.

[teal sandal]

Hand

I have a big backyard

@lyric dome congrats on a new scope!

[white prawn]

I have a decent size backyard, as well; just no observatory. If I were to get a 16", even a dob, I'd want to have an observatory so as to not lug it around.

[teal sandal]

Im planning to store it in a garage when i buy it

if i buy it

[white prawn]

That's where I store my gear right now. Which means on a good night I have to bring it all outside. Okay for an EQ5, maybe even EQ6R-Pro and 8". Less ideal for bigger stuff.

[fathom oak]

nice bro

[lyric dome]

Thanks, super bad seeing

[teal sandal]

there seems to be some good seeing today

but im a bit ill😭

[teal sandal]

That looks yummy

[lyric dome]

How is this process?

[teal sandal]

wow thats nice

[lyric dome]

Thanks man

Was a quick process, I don’t know how to process super well, I also think my scope is out of colimation

[white prawn]

Nice colors and processing, how'd you get that one?

[lyric dome]

Just a super small roi and 24k frames and good seeing I guess

[lyric dome]

Colomation could be better

And I need to dering

[ruby compass]

@somber stratus you told me to get it. So i did.

[fathom oak]

W

[main flume]

yay :3

@somber stratus how are teleXtenders for planetary?

[main flume]

what inchage is ur scope?

[somber stratus]

which specifically

[lyric dome]

6

[main flume]

idk 😭

i mean compared to Barlows

[main flume]

i hope I get good seeing one day 😭

[somber stratus]

A high quality barlow and high quality telecentric powermate/extender perform pretty similarly. I own both types and don't notice any meaningful optical difference as far as images are concerned. Namely 3x X-Cel Barlow, 4x TeleVue Powermate, 3x ES Extender.

Seeing is by far the limiting factor in any reasonably sized aperture

I've even used a cheap $30 single-element 2x barlow and even that performs similarly under average seeing.

[main flume]

o oke

[lyric dome]

@somber stratus what do you think?

[main flume]

personally i feel cringed out ^~^

[olive saddle]

Been a hot minute since I've heard that song, wow lol

[lyric dome]

Hahaha

[fathom oak]

bro stole my edit lol

@main flume @olive saddle

I posted this and he copied me lol

[olive saddle]

Mimicry is the purest form of flattery

[left spindle]

hello

[somber stratus]

First night of prolonged excellent seeing this evening. Random single stack with the 24".

[lyric dome]

awesome man, i got this but with 750 focal length not much to process

also jupiter few moments ago, not my best not my worse

ngl seeing was terrible

[left spindle]

Which scope?

[lyric dome]

150p skywatcher

[left spindle]

great

[main flume]

i got this with the same scope, my seeing was actually terrible

[grim gale]

Wind was ruining my frames with that wobbly eq2….. Need to change that mount

Gif with 10 frames

i think

[main flume]

woahh 6" newt?

[grim gale]

no 5inch

[main flume]

its 7

[main flume]

D:

waaaaaahhhhttt

[grim gale]

Oops

[main flume]

wdym oops?

[grim gale]

I just forgot how many frames i took

yknow

[main flume]

o oke

BUT THAT WITH A 5"

D:

what in the perfect seeing is that

[grim gale]

I was lucky

beacause seeing was perfect

but it was very windy

and that eq2 was struggling

[somber isle]

Dayum

[summer pebble]

image i got of mars about a month ago

[lyric dome]

8, first frame counts

Make it faster

Tea did you lose mininerd?

[fathom oak]

she left the server and rejoined

[lyric dome]

Why lmao

[fathom oak]

someone said the server would be better without her and she took it seriously lmao

[lyric dome]

That’s insane

@main flume the server would be better without heroic frog

I’m kidding I love him

[fathom oak]

https://tenor.com/view/frog-hello-darkness-kermit-my-old-friend-drm-gif-9482307

[lyric dome]

@somber stratus what brand of 2x Barlow should I use?

[carmine void]

Xcel

[somber isle]

Celestron omni is pretty good too

[fathom oak]

Celestron Xcel LX is definitely the best for the price

[somber isle]

Yeah I agree

[carmine void]

yep and u can get it for a good price on AliEx

[fathom oak]

or just buy used

[grim gale]

Why does my xcel 2x barlow like make the focal length bigger, but when proscesing jupiter, wavelets with the barlow just dont work, it just makes the image noiser

[fathom oak]

I don't think you understand how to use wavelets properly. This has nothing to do with your barlow. Sharpening makes the image noisy so you have to denoise as you sharpen. Idk what program you're using but I use registax and it has settings for sharpening and denoising right above each wavelet slider.

there are some good tutorials on youtube if you'd like

[grim gale]

When i use autostackert and registax with no barlow videos, wavelts work, but with barlow it just doesnt work

[fathom oak]

explain to me how you do your sharpening

[grim gale]

take the stacked photo from autostackert, and put in into registax and play around with the wavelets until it looks good

[fathom oak]

elaborate on "play around with"

do you just use the slider or do you denoise at all

and sharpen

[grim gale]

just slide the wavelets to the right, no denoise

[fathom oak]

In order to properly sharpen you need to mess with the sharpen and denoise values above the slider. As I said there are some good tutorials on youtube you can check out

[grim gale]

hmm , doesnt denoise make the image softer? Ill have to try toomorw

[fathom oak]

Yes. You need to properly balance the sharpening value and the denoise value so it's not too soft and not too noisy. A good balance of the two will result in a much sharper image than the unedited one

[grim gale]

Ok ill try toomorow, if i still have the raw data…

Thanks!

[lyric dome]

Send me a fresh stack tiff file of Jupiter with a Barlow I’ll process

[grim gale]

Thanks but i accidentally deleted my raw and stacked data thinking it was useless…..

[lyric dome]

My friends data just using discord as a way to transfer to pc

[fathom oak]

Jupiter having a disco party with all those colors sheesh

[lyric dome]

Fr 😭

Stupid phone camera fr

[rain mauve]

jupiter

not really that sharp

but kinda happy with the resulyt

result

[lyric dome]

Hell yeah

Is that a solar eclipse?

[rain mauve]

yes

solar eclipse

[lyric dome]

Awesome I have a few of those

[rain mauve]

i use dslr and 2x barlow lens right now

im comparing my vid and raw photos

[rain mauve]

stacked raw photos better

[lyric dome]

Yours is debatably sharper than mine outside of the chromatic aberration

Yesir

[rain mauve]

woahhh

insane detaill

[rain mauve]

how can i improve the image tho?

i use 80eq and 2x barlow lens

[lyric dome]

I can’t tell you right now. I’m driving but later I’ll go back and look at it.

[rain mauve]

okay

[lyric dome]

Click on it it’s an animation

[rain mauve]

looks very cool

[lyric dome]

Thanks

That’s my old 80mm scope

[rain mauve]

woahhh

the detail thoo

omg

[lyric dome]

Haha

My 80mm scope, like you have

Some advice; don’t use a Barlow (in my opinion)

Unless seeing conditions are near perfect, it doesn’t really help

[rain mauve]

do you use color camera?

i already take with no barlow lens actually

its actually worse

not that sharp lmao

[lyric dome]

Are you sure?

What kind of camera do you use?

[lyric dome]

Yes

I use sharpcap and solar system mode as well to correct chromatic aberration

[rain mauve]

yeahh

[rain mauve]

dslr camera actually xD

[lyric dome]

Those are good

How many frames are you stacking?

Also, are you aware of the time limit for recording?

You should never stack more than about two minutes of real time video because Jupiter will rotate, and when you stack it will be blurry

[rain mauve]

300

[lyric dome]

That’s very little

[rain mauve]

300 frames of photos

[lyric dome]

What is your maximum FPS?

[rain mauve]

if video

[lyric dome]

My Jupiter has 25,000

[rain mauve]

its like 3k

[lyric dome]

3K is better

[rain mauve]

yeahh

3k frames

[lyric dome]

What percentage of your frames are you stacking?

[rain mauve]

90

lmaoo

[lyric dome]

Bad boy

33% is the sweet spot

[rain mauve]

okay

[lyric dome]

Have

Haha

Those are with my new 6 inch

I have to go. We will talk more later.

Nvm

My dads driving

[lyric dome]

Awesome

Just remember that is based off of your highest quality frame, not the best images taken

It’s good because you have a high % of high quality frames for you

But even with that high I still would not use over 50%

[rain mauve]

okay okay

i use 1280x720 50 fps

or should i use 1920x 1080

but only 25 fps

[fathom oak]

hehe

[rain mauve]

heres with vids

[lyric dome]

Lordy lord

Use as small an ROI as you possible can

You want the highest fps you can

For planetary

Although you don’t track

Hm

And you don’t use sharpcap

If you don’t track then use a big ROI I guess, you want the most frames at the end

I would use a mid roi, then stop the video, move the scope again, and record again and repeat, as many times as you can in 3 minutes in real time

Then use pipp to put the videos together

[fathom oak]

Can you use ROI with dslr even?

[lyric dome]

He was talking about it so I assume? Idek

[lyric dome]

This

[fathom oak]

I wonder if that's lower resolution over the whole sensor or if that's actually using less of the sensor like real ROI

[lyric dome]

I have no idea tbh

That’s a good point though

[rain mauve]

What is roi?

I don't really know about it

My bad

[fathom oak]

Region Of Interest. It's a software thing that lets your camera use only a small bit of the sensor at once. This makes your FOV smaller but it gives you more fps which is good for planetary imaging

[rain mauve]

Ooooo

I don't use any software as well

As I attach my cam

I start to record 😂

[fathom oak]

yeah it's only for astro cams I think

[rain mauve]

No wonder

[lyric dome]

Unfortunately

[lyric dome]

@rain mauve next time do what I said from here and blow

Below

[ruby compass]

This would certently be some oversampeling👀

9x barlow with a 1200/203

🥲

Just a casual 10800mm of focal lenght (with an 8")

Thats right. I wouldnt

😂

Its 2 3x barlows

Stacked

Yes

Well I would obv not reach focus

The reason I even have 2 barlows is cuz I uppgraded from a shit one to a really good one

[rain mauve]

okay

thank you for the tips

and how can i know i have to do roi?

[fathom oak]

XCel LX is based

[ruby compass]

Frrr

The build quality is crazyy

I might be able to use it for my first time today

!!

[ruby compass]

the seeing i had today was the worst i think enyone ever has gotten.. (This is jupiter at 40 degrees above horizon in perfect focus (IR685nm)

yep. this is mars.

vs what it looked like in an good frame

[woven tundra]

[rugged knoll]

@ruby compass

[ruby compass]

I dont think thats wors

mine was in ir brw

[rugged knoll]

yours has bands

[ruby compass]

Cuz of the good equipment

Tho I did get this

[rugged knoll]

this was with a 150mm

[ruby compass]

It was actually so bad that jupiter was blinking in the sky.

..

[rugged knoll]

that happens pretty often for me

[late spoke]

Barlow up ahh

Bros gonna be seeing exo planets

[somber isle]

https://tenor.com/view/retro-disco-ball-shining-sparkle-gif-17029777

[lyric dome]

Average seeing

[somber isle]

I need to re-shoot

Seeing was buns

[vapid depot]

https://www.flir.com/discover/rd-science/lunar-eclipse-when-viewed-in-thermal/?srsltid=AfmBOoruu3SXrZJhB7HG8hx_2A3VWcgCqaDEgqGLAhBeUsB5Tkz1Iu6g

interesting.

@sour cradle

[sour cradle]

ive seen that already
and i hate the lack of up to date documentation on the 110 dollar module i bought so much

[lyric dome]

Friends Jupiter

[main flume]

JUPITER, MORE LIKE, GUPITER

[ruby compass]

Solareclipse thru an Samsung galaxy s23 Ultra (no telescope no solar filter) 1.5h timelaps

[lyric dome]

There is some kind of solar filter in phone cameras inherently because if there was not than any camera pointed at the sun would burn, anyways super cool timelaps

Wish I could have seen it

[ruby compass]

I used sv183 and sv220 for it

[lyric dome]

I forgot that Samsung has cameras haha

[vestal root]

i suck

[thin aspen]

hi guys, do you know what this ring around mars is formed from? Thx

[candid flare]

Over sharpening artifact

[thin aspen]

This is normal then? Or is there a way of preventing it?

[somber stratus]

Yup. Normal, as Yoships has explained.

[sour cradle]

Youd think but no
The sun hits such a small spot size, that heat can dissipate

[lyric dome]

Wow

[white prawn]

My accomplishment - imaging Mars between this a few months ago.

[sour cradle]

this is the same reason that all sky cameras dont destroy themselves during the day time

[main flume]

which is why pigeons cant fly

[digital steppe]

how

[digital steppe]

what satellite is that

[charred apex]

and my shot of solar eclipse

[keen ginkgo]

2nd time ever doing a planetary/solar timelapse. The frames were untracked so i think im pretty proud of myself

[charred apex]

What scope did you use?

[keen ginkgo]

Tamron 18-400mm

[low tendon]

are those trailed or are the lines solarpanels?

insane

great pic

just realised i havent shared my fav moon pic here lol

zoom in for details

[devout hound]

damn that’s crazy i got a pic of that exact spot i think

but with a super cheap telescope i still haven’t got the moon on my better one

[fathom oak]

um what did you do

please tell me you didn't look at the eclipse with sunglasses on your eyes

only phone I hope

[vestal root]

eyes too

[fathom oak]

regular sunglasses?

[vestal root]

2 glasses put on top of eachother

[fathom oak]

oh no

[vestal root]

polarized

[fathom oak]

that does not work in the slightest

you most likely damaged your eyes

[vestal root]

oh no im blind

[fathom oak]

never look at the sun without proper solar glasses or solar filter

how long did you look at it

[fathom oak]

if only looked at it for a few seconds then you probably won't go completely blind, but it's still definitely dangerous

[charred apex]

In my country there is a news telegram channel, where they wrote that there will be a solar eclipse.
So at the end. they had a caption:
"Set alarms and get your glasses ready"

so i think some people hurt their eyes a little after news of this quality

[teal sandal]

which channel

[charred apex]

No, most people weren't interested in this event, some people had cloudy weather.
It's just that this channel is one of the most popular sources of information in the country. And the information itself is of low quality. Sometimes they write that a person died, although he is alive. Sometimes they advertise on the death of a blogger and even publish astrological forecasts.

[teal sandal]

bro im from the same country as u are

I just want to look at the channel myself

[charred apex]

oh privet)

[charred apex]

i think you knew this. just like a woodcutter's tool)

[main flume]

hey, dont watch them, they want to be left in private

[rain mauve]

venus

[somber isle]

Wow that's amazing

[main flume]

space banan

[somber isle]

Holy cow thats detailed

[summer pebble]

conditions were below average too!

pretty surprised with this level

[main flume]

mooen

[ruby compass]

@main flume i need ur help.

[main flume]

with what

[ruby compass]

processing an jupiter image (i cant remove noise nor split channels)

this one

[lyric dome]

ill try

[ruby compass]

I have better data

My friend deritated it

Do you want the derotated version?

@lyric dome

[lyric dome]

yuh

[ruby compass]

Okay

Here

[lyric dome]

what is ur camera pixle size

[ruby compass]

Yeah mb

3.75

And focal 3600

[lyric dome]

did you use barlows?

sorry bro no luck here, the colors are likley do to cheap glass with chromatic abberation, if you use sharpcap you can fix this by using "solar system mode" on the bottom of the options, you also should have an IR/UV cut filter

[ruby compass]

Yeah

The barlow i used at that time wasnt the best

@lyric dome you could make it mono tho

[lyric dome]

Barlows aren’t really the issue it’s the seeing that is

Barlows will multiple how much seeing matters

Since Jupiter is bigger in frame, you get less fos

[ruby compass]

Its really good seing lmao

[lyric dome]

Whats your aperture?

[ruby compass]

203mm

[lyric dome]

In inches?

[ruby compass]

8"

[lyric dome]

I got this with a 80mm 150$ telescope with decent seeing with no derotation, I think you are using wayyyyy too high focal length mine was only 900

[ruby compass]

Well I think this looks quite good. No?

[lyric dome]

You use sharpcap?

[ruby compass]

This was with 3600mm

[ruby compass]

No

[lyric dome]

Little green but looks good

[lyric dome]

Firecapture?

[ruby compass]

Yeah. Processed by Tom

[lyric dome]

I see

[ruby compass]

No. Asi CAP

[lyric dome]

Sigh haha okay

[ruby compass]

Do you want to see what bad (HORRIBLE seeing) looks like?

This was in IR when jupiter was 45° above horizoj

[lyric dome]

Well that’s what you get with anything on horizon

[ruby compass]

Horizon*

[ruby compass]

It was high im the sky..

[lyric dome]

You misunderstand

When your scopes focal length is a certain point, using 3, 4, 5x Barlow will also make the seeing conditions matter 3, 4, 5x more

Sometimes using no Barlow is better

The air needs to be very still

[ruby compass]

Tell me wich one is best..

The diffrnece between 3x barlow and no barlow

[lyric dome]

What is your scopes standard focal length

[ruby compass]

1200mm

[lyric dome]

The same night?

[ruby compass]

No

[lyric dome]

Bro that’s way more than enough

[lyric dome]

Then comparison is irrelevant

Why are we talking about 2 different photos from the one I tried processing anyways

[ruby compass]

It isnt cuz my pixels are massive

@lyric dome I have already reached peak sharpness without barlow and it looks shit

[lyric dome]

Your camera is probably built for deep space

[ruby compass]

I dont think the zwo asi 224mc is for deepspace lmo

Lmao*

[lyric dome]

More often than not, bigger pixels are better for dso, and small for planetary

[ruby compass]

Yea but the camera i have was made in 2016

[lyric dome]

Cool

How much was it?

[ruby compass]

Cuz I live in sweden it was 300$

In the US its 149 tho

[lyric dome]

Tf lol

Crazy

If it’s zwo would be 170 now

They increased all prices by 20-30%

[ruby compass]

What.

[lyric dome]

Recently

Yeah

[ruby compass]

Why?

[lyric dome]

Tariffs

I still like trump but damn lol

[ruby compass]

Me too lmao

[ruby compass]

Btw if you think the colors are shit u can still process this

@lyric dome better colors

Btw PLEASE remove blue channel

And change it so its RGG

[lyric dome]

I’ll try

But yeah pixels are so big

[livid sierra]

You’re talking out of your ass

[lyric dome]

I’m talking based on my experience and what other experiences planetary astrophotographers have told me

And things I have tested

[livid sierra]

Well your experience is wrong then because 1200mm f/6 is wildly undersampled for an imx224

[lyric dome]

Is higher F ratio change things?

[cloud copper]

For an imx224 you have to go big with your fl

[lyric dome]

I see

See that I did not know

[cloud copper]

Talking from experience with my setup

[livid sierra]

Even 3600mm f/18 here is undersampled

[lyric dome]

My 3 inch 900mm fl had F/11

[cloud copper]

I use 4600fl and I’m still not quite properly sampled

[livid sierra]

See so you were talking out of your ass

[lyric dome]

How?

[livid sierra]

Stating that 1200mm is way too much as a fact

[cloud copper]

Fax

[lyric dome]

I didn’t say it’s way to much

[cloud copper]

1200 is ok for deepsky ig

[lyric dome]

I said I don’t think you need to triple it

[cloud copper]

You do

[lyric dome]

Maybe for that camera

[livid sierra]

Whatever you said was wrong

[lyric dome]

Maybe it was for his case, still wouldn’t say I was talking out my ass everything I said applies correctly to both of my setups I’ve had

[livid sierra]

Different scope different camera

[lyric dome]

I did not know that the laws of how things work completely change

AJ smadi and Jamie both told me when I first started a few months ago that using Barlows only works well for planetary if you have very good seeing

[livid sierra]

I don't know those people and they're wrong

[lyric dome]

You follow them lol

On Instagram

[livid sierra]

Looking at your username you're probably using an IMX715

[lyric dome]

Asi

[livid sierra]

That sensor has tiny pixels that's why it's usable without a Barlow

You're often already at/close to good sampling

[lyric dome]

I see

I think I have .86 or something

[livid sierra]

With larger pixels though you're gonna need a Barlow otherwise you're undersampled and you will never be able to resolve any of the detail that you could potentially ever resolve

[lyric dome]

I see

Well thanks for the insight

Your Instagram photos are super cool

[livid sierra]

Thanks preciate that

[livid sierra]

Tbh I follow lots of people, I don't know many of them

[lyric dome]

Gotcha

[livid sierra]

For lots of them there is lots of room for improvement and I don't understand why they do certain things that they regarding their methods

[lyric dome]

Definitely

I tried moon for the first time last night, any tips?

[livid sierra]

Looks fine overall, the blurriness could be caused by seeing or collimation or something

[lyric dome]

Yeah I I’ve been struggling with colimation since getting my new scope

So many people say the same thing find a star, de-focus, and make it all even but I try that and it just doesn’t seem to be colimated

[livid sierra]

You should only defocus a very little bit, too much and it will always look perfectly round no matter how good or bad the collimation

If you have a newtonian, I recommend using a simple collimation cap (can DIY one or buy one for like $5), collimate the secondary and primary with it (I do both using the collimation cap) and then check on a star

Collimating on a star can be tough in the beginning, I haven't fully mastered it myself. Without tracking it is near impossible unless you do it on Polaris, collimating moves the fov around so it's tough

[lyric dome]

Yes every time I move the star I manually move the scope again

Could you sent a link to a good cap?

I have a 6inch

[fading plume]

I literally use a piece of scrap plastic with a hole in it.

[lyric dome]

But doesn’t the hole need to be in the very center

[cloud copper]

How do you collimate the secondary with a collimation cap

I can’t get it right

[fading plume]

Sure

[livid sierra]

Just make sure there's nice and equal space all around the secondary

And the secondary itself is seen as as close to a perfect circle as possible, looking through the cap

[livid sierra]

https://www.firstlightoptics.com/other-collimation-tools/rigel-125-aline-collimation-cap.html?_gl=1*1rvjo3t*_up*MQ.._gaODY1NDY5NTEyLjE3NDM5NDU0MDk._ga_F6VGWQ0MW9MTc0Mzk0NTQwOC4xLjAuMTc0Mzk0NTQwOC4wLjAuMA..

[lyric dome]

This works with camera or no?

Is the issue that I’ve been trying to use my camera to colimate

[livid sierra]

No, use your eye to look through it

Collimate using your eyes with this, then check and maybe correct using camera on a star

[lyric dome]

Oh okay

[rugged knoll]

if you want to use a camera you need an allsky lens

[fathom oak]

I image at 3600mm with my 8" lol it's completely fine. A bit undersampled even (with my camera at least)

[ruby compass]

@somber stratus thank you for telling me to buy this barlow. It really is amazing.

[lyric dome]

Awesome

Maybe my camera is better for planetary then most lol this is with 6 inch with 5/10 seeing and no Barlow

[lyric dome]

I see a few really good frames

[fathom oak]

the first one is not 5/10 seeing

[summer pebble]

HDR Half Moon

[lyric dome]

Dude my seeing scale is worse than yours I have less experience, what would you say it was (they were take the same night)

[misty glen]

Moon like 10 minutes ago

[lyric dome]

Insane

[misty glen]

thx

[white prawn]

Late to the party, but can we talk about camera FOV? 😆

[charred apex]

Good morning)

[white prawn]

1200mm isn't too much with an 8" aperture. I have a 3x on my 8". I got this: https://discord.com/channels/794642864218439681/1352127801909579826

That said I won't argue the notion/fact that as focal length increases, seeing matters more.

[white prawn]

Hi

[charred apex]

I can’t believe that it’s 80 mm. How?

[white prawn]

I doubt that the statement is true. I've seen what an 80mm telescope can resolve. My 130mm at 2250mm gets this on a good night.

[charred apex]

Wow that looks beautiful. maybe I should improve my skills

[white prawn]

I still need to work on mine.

... and get a night with actually decent seeing.

[ruby compass]

Frr

[ruby compass]

Yeah. What about it?

[charred apex]

I don't think the weather will give me a chance anytime soon)

[white prawn]

Nothing serious, thus the 😆 .

I like the FOV you used; it's similar to what I use to capture.

I just tighten it down to 500x500 on the stack. 🤷

Probably a personal preference, really

[ruby compass]

I also do. Just didnt do it due to the fact that I wanted calisto in the image

[white prawn]

To be fair, I saw her out there and figured that was probably why you left it. Of course I saw after I said something about the FOV.

[ruby compass]

Yh

Btw.

What do you think of the view i got yesterday on The moon with my new barlow?

@white prawn

[ruby compass]

This

[white prawn]

Nice

You remind me that I might need to learn my way around. Or how to find marks because I'm still trying to find the one I pointed at.

Okay, I can NOT get the color right on this. Wavelets are okay though.

[somber isle]

Was just messing around and got this somewhat decent image

[ebon sage]

getting dark at 5:30pm is weird

[somber isle]

It wasn't 5:30 for me

[lyric dome]

It’s true lol, it’s a refractor

[lyric dome]

Some other ones

My talent grew drastically in this time frame

Went from this to this with the 3inch

Now I’ve reached these

[charred apex]

If it’s really made at 80 mm, then I’m shocked

[lyric dome]

I was too

No the new ones are 150mm

[lyric dome]

These are 150mm

[charred apex]

Ок

[lyric dome]

These are 80mm

[charred apex]

But it’s still very good

[lyric dome]

Yup yup

[urban ocean]

i do wonder: the quality between a dedicated cam vs a phone camera on an 80mm is night and day. is it just because of the pixel size you get on a phone camera that provides poor sampling?

[lyric dome]

I’m not sure tbh

[lyric dome]

It’s about frame rate as well

[urban ocean]

no doubt frames are important but i think the limiting factor is your resolution per pixel

[lyric dome]

Phone cameras were not built to look into telescopes they are built for wide photos, Astro cameras are built for telescopes

[livid sierra]

Framerate, pixel size, not having to image through a cheap eyepiece which introduces more CA and such

[lyric dome]

Ima let duif talk before I talk out my ass again

[urban ocean]

im actually trying to find a conversion of resolution of eyepiece projection compared to prime focus

[livid sierra]

It is not impossible to get good images with a phone if you use good equipment like a high quality EP and an ADC, but the same goes for astrocams; if you don’t use high quality equipment like a good quality Barlow and an ADC you will hardly get good images too

[lyric dome]

Also phone cameras aren’t good at color right?

[livid sierra]

Also it’s important to be able to get raw data, lots of phones compress the data that comes out of the cam

[livid sierra]

Also true

[lyric dome]

My first Jupiter I had to turn the brightness down so much it looked mono

[urban ocean]

i can confirm

some results ive been getting recently look interesting though using different capturing apps: you can just see the GRs on the left there

[lyric dome]

Yup

[urban ocean]

today i still have a preference imaging with my iphone se over my 13 even though ive looked at the specs and they should be the same

for some reason the se samples better

[charred apex]

And how do you shoot on your iPhone? Do you start the video by attaching it to the eyepiece?

[urban ocean]

yeah i use eyepiece projection by mounting the phone camera to the eyepiece: for the planets i use the shortest eyepiece possible

[charred apex]

It’s just that I do something like this, and it seems to me that there is a secret how I can do it better

[urban ocean]

you definitely want to reduce the exposure such that you dont overexpose your planets and wash out any detail: this will probably improve the quality of your images the most in the beginning stages

[charred apex]

That’s why I tried to set the frame rate higher

[urban ocean]

that would help yeah, although the software i use to capture often caps my framerate at 30fps

[charred apex]

It’s just that the iPhone often tries to find the trick by itself. And it often spoils everything

[urban ocean]

very important question: if you're using the stock camera app have you turned on AF/AE lock

[charred apex]

Idk how to do it)

https://tenor.com/view/facepalm-gif-6565016535492739421

[urban ocean]

on stock hold down on the screen until it says it on the top: this will stop your camera from readjusting focus + exposure every time the planet moves out of frame

[charred apex]

Wow it works. Thanks

[thin aspen]

Does anyone have any experience with combining two pictures of the moon at different phases, into one moon image to improve crater shadows?

[lyric dome]

I know a guy on Instagram that has done this, want his Instagram?

Or I can get yours and add yall to a group chat

He doesn’t have discord

[thin aspen]

Ye sure thanks, I think I saw his which gave me the idea.

[thin aspen]

anyone else experienced this problem recently with Registax. I get this line in-between two adjacent processing regions.

[livid sierra]

The fix is to use Astrosurface instead of Registax

Data looks pretty good overall tho

[thin aspen]

its a pain since this never happened before

[fathom oak]

Click the "do all" button maybe?

[thin aspen]

Did that, it’s just in between the the tiles it covered

[left spindle]

That looks more like a stacking error , were you trying to make a mosaic?

[livid sierra]

I would sharpen the individual panels first and only then combine them to make the mosaic

[vestal root]

i suck

[olive saddle]

What equipment was used? I think this is more of a limitation of gear and not necessarily skill

[thick heron]

Look who's back.

[lyric dome]

SATURN

[thick heron]

Aphelion clouds are setting in over Tharsis.

[late spoke]

Forgot to post this

Mineral moon attempt with a heavily undersampled rig

Weird drizzle artifacts but meh lol

Data isn’t good enough for me to bother retrying

[rugged knoll]

no idea what that means🔥

[fathom oak]

oversharpened

[somber isle]

Is this too bright?

[rugged knoll]

Yes

[vestal root]

some telescope 40070

[olive saddle]

Sounds like it's one of those cheap short tubed refractors, just going by the aperture and focal length

So likely not the greatest optical quality

[vestal root]

nope

got the wobbles too

[main flume]

nah, ur using a phone

and a cheap frac

[main flume]

slightly

just tone it down a little

[main flume]

ooo, coool, words i dont understand :3

[thin aspen]

I mean between the tiles in registax, like when you press “do all” it sweeps across tile by tile until it has processed the whole image.

[livid sierra]

Registax always does that

But use astrosurface lol

[thick heron]

I saw this last night. Southern hemisphere has the ecliptic at a higher angle so they get a decent view.

I'll take mine over Tom's situation of "wait, Saturn is back?"

[lyric dome]

Yep yep

Jamie was one of the first people that taught me how to do plantary

[fading plume]

Might try it this weekend

[lyric dome]

Dope

[lyric dome]

Awesome

[somber isle]

Wowie. What's this taken with?

[thick heron]

FlexTube 400P and Uranus-C today, Uranus-M and 850nm IR-Pass yesterday.

[somber stratus]

I’ll still be saying that in a few months tbh

[sharp ridge]

Nice Titan image

Very high res and cool

[sour cradle]

THATS TITAN????

[rugged knoll]

excuse me what

[thick heron]

Yes. Very cool to catch it like this.

[rugged knoll]

i thought it was saturn that wasn't that high quality for the scope size bc of being super low on horizon or smth

how the hell

[thick heron]

I know how...

I just lied.

It's Saturn.

[rugged knoll]

zamn

i have been tricked lmao

[lyric dome]

Hey Ethan, just followed you on insta, did you see AJ got nasa photo of the day with his ISS Venus ?

[thick heron]

Not the AJ I initially thought you were talking about.

[sand hedge]

The Mineral Moon

[elder venture]

[vestal root]

just a phone this time

[ruby compass]

beutiful.

[main flume]

through a window too

[white prawn]

HOW. DO. PEOPLE. DO. THIS.

[olive saddle]

Take many images of the moon, stack em like a normal astrophotography image, really crank up the saturation, and play around with other settings in order to bring out the colors in the titanium and iron oxide deposits, whilst keeping the white and grey rock looking the way it's supposed to.

You can even get a questionable quality mineral moon with just a single image, if you edit it right

This was one I did, obviously it doesn't have as much color in it due to it being only a singular exposure, but you can still see that it has some nice blues and browns.

[white prawn]

Basically I could potentially do that with any lunar image

[sour cradle]

yeah
theres no special techniques
just make sure color is balanced, and then crank the shit out of saturation

[sour cradle]

this isnt even a very good image, but it still works for mineral moon

[ruby compass]

@sour cradle how do people fix cromatic issues when making mineral moon?

[sour cradle]

chromatic aberrations?

[ruby compass]

this is what it looks like for me

[sour cradle]

just run an rgb align in registax

[ruby compass]

regi thinks my data is monchrome

could u vc rq so i could show u one of the issues?

[sour cradle]

ye

[lyric dome]

Haha

[terse night]

Yeah and if you decompose the image in luminance and crominance you can boost saturation without making CA insane. This here is a single sub and colours are very evident:

[terse night]

Make two copies of the image where you turn saturation to zero in one of the images. You'll only sharpen this image and, since it has no colour, it also has no chromatic abberation, then you recombine them to get colours back with pixel math, see the image above for the result.

[ruby compass]

I dont have the problem anymore

Just had to rgb allign

@terse night look at this image!

[fathom oak]

"colours" brit spotted

[terse night]

I'm Italian bruv

[fathom oak]

oh lol

[terse night]

Nice but there is some ca I think

And what's up with the left side of the image?

[fathom oak]

looks like stacking artifacts

[ruby compass]

Nope just bad WB

[ruby compass]

Stacking issues

[lyric dome]

What do you use to stack?

[ruby compass]

Autostakkery

[lyric dome]

Make a Drive with your data and send it here

It shouldn’t have stacking errors

[fathom oak]

stacking lines are pretty common for untracked lunar data

[lyric dome]

I have none

[fathom oak]

don't you have a tracking mount?

[ruby compass]

I will in like 1.3h

[lyric dome]

Yes but it’s not working lately

[digital steppe]

I shall attempt to diagnose your problem

[lyric dome]

The batteries died

[digital steppe]

I think you should get new batteries

[lyric dome]

Thank you for the advice

[waxen solstice]

Repost

[lyric dome]

Not bad bro

[left spindle]

Am i good at planetary

[rugged knoll]

show your images and equipment used

[left spindle]

114/900 scope, first 2 are with phone rest with webcam

I have more better images but they are on my laptop (those are taken with same thing but also with 2x barlow)

[left spindle]

Seach webcam in planetary pics, most of then are mine

[rugged knoll]

that is pretty good

what size was mars when you shot this

[left spindle]

I dont remember, but it was close to opposition

[left spindle]

Thx

[white prawn]

Probably about 6,800 km across the middle.

[lyric dome]

Pfffff

Guys someone please tell me how to rotate the outline

Outline only

@livid sierra

[somber stratus]

"n" and "p" iirc

"shift+n","shift+p","ctrl+n","ctrl+p" for varying step size.

[lyric dome]

THANK YOU TOM

[lyric dome]

Okay so my 1st derotation attempt was bad…

But that’s good I have to learn

[lyric dome]

So do I sharpen the images the exact same amount and then put them in? Or do I not sharpen at all?

Because that one I didn’t sharpen at all

[somber stratus]

You should sharpen before DR

[lyric dome]

all the same?

[somber stratus]

Well, normally you sharpen everything the same in batch anyway, but they can have slightly different sharpening settings depending on seeing variation

There is also the weighting option in the DR window so you can give higher weightings to the better stacks.

[lyric dome]

i see, thank you man

sharpening after deff isnt the way to go, but i like the low noise

[lyric dome]

Hey @thick heron, I can’t figure out how to resize the outline, I can zoom in and out but not resize

i think it needs to be a little smaller

[thick heron]

Page up and down.

The screenshots Tom posted earlier cover it all.

[lyric dome]

What button is page up and down on a windows

😅

[thick heron]

Is this a laptop?

[lyric dome]

Yes

[thick heron]

It might be something like CTRL+Arrow keys.

[lyric dome]

Okay

derotating is hard 😭

[thick heron]

Or maybe Fn+Arrow

[lyric dome]

not good 😅

wayyy too bright

I give up for now, my normal photo is better haha

Derotate attempt

Normal

[fathom oak]

yeah it's a bit oversharpened

[lyric dome]

I think I just suck at dr lmao

[somber stratus]

Tbh the benefit of derotation is only really noticeable for larger apertures, where you're having to stack at lower and lower %s, and hence have a reduced SNR.

Seeing is all too consistent for small and mid apertures that a single stack at 50% isn't too dissimilar to 5 x 10% derotated.

[lyric dome]

Alright bro, thank you

[lyric dome]

Tom, can you show an example of a normal photo vs a dr photo

[digital steppe]

4 pixels of Ganymede

[teal sandal]

minecraft

[rugged knoll]

i have 150mm and there is a huge difference for me

[rugged knoll]

bro😭

[lyric dome]

It really helps the edges, cool

And the noise

[lyric dome]

Teach me your ways

[low oar]

Tom owns this chat

Horrendous seeing today

[lyric dome]

He is our leader

[low oar]

Worst I’ve ever seen

[lyric dome]

I haven’t even tried Jupiter since this day, too low in the sky

[low oar]

Fair

Better seeing

[lyric dome]

Really good

[low oar]

Thanks

Made it look a tad less dead 😂

[rugged knoll]

rgb align please

[ruby compass]

Holy.

[lyric dome]

All 4 moons, Callisto is the dim one

[low oar]

Mercury and Venus yesterday during the day

[olive saddle]

Woah, good Mercury

[main flume]

morecurry :D

[main flume]

which one dslr, im deaf

[zealous smelt]

I rediscovered this Jupiter image from January 30th 2024, odd part of the northern equatorial belt stretching up north. I’ve seen images from like a few days prior and after where there’s no such prominence

[livid sierra]

1st of February 2024

It’s right there

[zealous smelt]

Cool

[lyric dome]

Is it fair to give up on Jupiter until later in the year because of its dark out angle in the sky for eastern American?

Like is it possible to get seeing this good again? Like anytime soon?

This was live view

[livid sierra]

Not sure what you mean

Jupiter is getting harder now because it sets almost right after sunset

Just gotta wait for it to start rising in the morning again and then slowly we will get to it being up in the night again

[lyric dome]

I’m saying for my location and this time of year, is it worth trying still?

Cuz idk what else to go for planatary wise rn

[digital steppe]

go for a dso, trust me

just try it

[lyric dome]

I don’t think sharpcap works for that tho

[digital steppe]

learn siril, or if you dont wanna learn use DSS

[lyric dome]

@tidal crow how do you do dso with sharpcap?

[digital steppe]

first get some data

[lyric dome]

Sharpcap is used for recording

[lyric dome]

THATS WHAT I MEAN

[digital steppe]

oh, I feel stupid

[lyric dome]

😭

[digital steppe]

im not a dedicated camera person

[lyric dome]

Right

So what do I use to get the data

[digital steppe]

dont you just set your exposure, gain and go for it

or is that not how sharp cap works of smt

[lyric dome]

Do I record or take single photos?

[digital steppe]

prob single, like 1 second exposures

first choose your target

[lyric dome]

So I need to manually click “snapshot” every single time

[digital steppe]

cant you program it to automatically take photos

[lyric dome]

I don’t know how to take single photos sob

I’ve never had to

[digital steppe]

we should discuss this in ap chat

[lyric dome]

Yeah

[tidal crow]

There is a sequence tool for shooting separate frames in one go

[lyric dome]

Ohhh, and what about live stacking?

[tidal crow]

That works too

[livid sierra]

🤷‍♂️

Only way to find out is by trying

[lyric dome]

True haha

[livid sierra]

But like I said Jupiter sets very close after sunset so it’s very low

[lyric dome]

Exactly yeah angle in sky is low

[livid sierra]

And only Mars is up right now, planetary season is ending

[lyric dome]

And mars is only getting farther away yeah

[livid sierra]

Gotta wait for the planets to start rising in the morning again. In some locations Saturn is already somewhat doable shortly before break of dawn. Not for me though, at 52°N

[lyric dome]

Damn haha

[livid sierra]

Depends on your location how long you’ll have to wait to start imaging the planets again

[lyric dome]

I’m 35*N

That’s even worse right

[livid sierra]

No, better

[lyric dome]

Ohhh, and if I’m up on a mountain?

[livid sierra]

Closer to equator, so

[lyric dome]

I see

[livid sierra]

What about it?

[lyric dome]

Will being much higher than horizon matter

[livid sierra]

It’ll help that your horizon is low, but being up on a mountain will have a negligible effect on the time the planets rise

Like a fraction of a second lol

[lyric dome]

And is it visible visually right after sunset or like

Have to find it

[livid sierra]

Saturn?

[lyric dome]

Ohhh you mean sunrise

Yes

[livid sierra]

Saturn is hardly visible after sunrise, perhaps if you know where to look

[lyric dome]

Seems like a lot of effort to not just wait

[livid sierra]

But best to image before the sky gets too bright

[livid sierra]

What do you mean?

[lyric dome]

Like seems like a lot of effort to probably get bad photo when I could wait a few months

[livid sierra]

Depends on who you ask. If I could, I would start imaging again as soon as possible. Just because I like seeing the planets change through time in my own data

And the more you image the higher your chance to catch a moment of good seeing

[lyric dome]

That’s true

At horizon it’s like 600 miles of air 😭

So gotta be really lucky

[livid sierra]

I’ve been having to image Saturn at 15-20° before sunrise here the past two years

[lyric dome]

Dang

Does it not get any higher?

[livid sierra]

In 2023 it only rose to 27° at its highest point, 2024 it got to 30° iirc
