Planetary Imaging

[rugged knoll]

How do you do an hdr

[woven tundra]

All i know is that instead of a video he takes loads of pics with one overexposed

Like hundreds of moon pics, with one overexposed

Phone can too

[elder venture]

How well would you deem a 12'' thats untracked?

[thick heron]

Might be practical with a larger sensor like the IMX585. Never done it with a scope that large though.

FOV is about comparable to the tightest I've done untracked.

[elder venture]

Another option I have is a Class Cass 6'' F/12 I could get and put on my HEQ5

thats about 1850 Focal Length

[thick heron]

You can always DIY a ServoCat or OnStep system onto the dob if you're inclined to put in the work.

[elder venture]

i have no idea how that would even work

I mean i can prolly figure it out with my dad

[low oar]

Fancy photoshop

[ruby compass]

hi

[ruby compass]

Saturn 15/07-25. my first planet since april. (IR685NM)

Venus (really bad)

[native plume]

bad focusing or bad weather

[teal sandal]

Looks out of focus

[terse night]

@somber stratus escuse me for the ping, does it looks like DRIZZLE3 is doing something here? I'm very undersampled in this shot but the two results seem very similar to me.

[somber stratus]

resize the small one 300% and see if it changes at 1:1.

I don't see any benefit from drizzle personally.

[terse night]

Meaning I just upsample it 3x?

I also have this comparison, again very similar to me

[ruby compass]

2 degrees above horizon

[ruby compass]

kinda was yh

My first image of a star since april. (Vega after sunset)

great colimation

[low oar]

That’s cool

[ruby compass]

also new and improved venus

[low oar]

I just realized I have Venus data to edit

[ruby compass]

nice

also why its elongated is due to it being very low in the sky

@low oar new improved Saturn

old vs new

differnet data btw

[low oar]

Nice

Venus July 8th

Uv/Ir cut filter

[low oar]

Could be a smidge out of focus or a combination with wobbly seeing

[ruby compass]

Literally perfect colimation

[ruby compass]

What.

[low oar]

Didn’t say anything about collimation 😂

[low oar]

What?

[ruby compass]

Nvm read combination as colimation

[ruby compass]

Its killing my happines

[low oar]

Oh

Don’t let that happen lol

Be happy with ur pics

[elder venture]

How did you

Get that good detail with just uv/ir cut??

[white prawn]

I'm interested to hear that, as well. Guessing a low light setting.

But isn't a lot of signal from Venus in IR so wouldn't IR Pass make more sense?

[elder venture]

The point is to reduce signal in venus.

Its so incredibly bright you have to isolate light

Infrared shows deep clouds/surface

UV is for general clouds

[white prawn]

So you could capture some general clouds with a UV/IR cut filter

Fine-tune gain/exp/brightness settings.

[low oar]

Idk how it’s possible either

But I did it lol

[white prawn]

Which ... is true pretty much for anything, just with Venus you're working with an object that is brighter than normal.

One of two things:

1. You got the settings exactly right and your seeing was fantastic.
2. Something else is at play, maybe another piece in the imaging train that you forgot about.

Either way, I hope to be able to capture some details on Venus.

[low oar]

My “imaging train” is the uv/ir cut filter lol

And seeing was fine I fuess

[elder venture]

Yes, but it would be INSANELY bright still.

[low oar]

These were the same morning

[elder venture]

which cam and scope

[low oar]

Uranus C and a C 11 and Uv/Ir cut filter, nothing elese

[elder venture]

OOO A C11

[elder venture]

How bright was it and how much int

[low oar]

I have no idea lol it was July 8th

[elder venture]

aa

oh wait

given that it had to be fairly bright

[low oar]

My friend did better than I did

[elder venture]

my assumption is the exposure to make the background appear black, paired with the fact that you have such a wide aperature and long focal length with a high res camera allows you to get a real-colour image of the clouds

[elder venture]

waaa

[low oar]

Venus rises when it’s still dark anyway

[somber stratus]

who's is this?

I recognise the processing but can't put a name to it

[livid sierra]

Aj.smadi

Needs some more sharpening though.

[somber stratus]

more time in the slow cooker

[thick heron]

Do people just not care if their cooked limb makes the planet look like a watermelon?

[livid sierra]

Those are the ice water clouds obviously. It’s real detail.

[somber stratus]

I understand the cooked monochrome images, for ALPO etc.

but otherwise absolutely not

[white prawn]

I do, that's why I get frustrated at about 99% of my Mars images

[low oar]

Aj

[teal sandal]

dang seeing clouds with just a uv ir cut is insane

what scope does your friend have

[somber stratus]

It’s easy if you nuke the wavelets.

Cloud detail is there in all bands

[teal sandal]

oh thats where the sharp edge came from

[somber stratus]

Partly yeah

[teal sandal]

will it be possible to get 'em clouds with my mak in september?

5 inch aperture

[low oar]

He has a 9.25 and I used a 11

[teal sandal]

nice

dang

venus will be quite smol

but ill prolly shoot without a barlow

cuz clouds

[low oar]

Yea

[teal sandal]

this makes it super smol

[low oar]

lol

This is mine

[teal sandal]

i mean i shot mars when it was small

with my mak

and this is with my old zwo 224 mc i have player one 664 now

so i should get... some? detail

[teal sandal]

what cam do u have

[low oar]

Uranus c

[elder venture]

A fellow 664 enjoyer

https://tenor.com/view/ah-i-see-you-you-are-man-of-culture-as-well-gif-26222969

[teal sandal]

Hell yeah, I love my 664

[elder venture]

mine has yet to arrive

[teal sandal]

what scope are you pairing it with?

expect amazing deep sky and planetary with this cam

also if u have questions abt it u can ask me ive used it for half a year already

[elder venture]

130PDS and hopefully a C8

[teal sandal]

oh nice

did you order the one from zwo or player one

[elder venture]

dude

i am the Nr. 1 zwo hater

[teal sandal]

https://tenor.com/view/ah-i-see-you-you-are-man-of-culture-as-well-gif-26222969

[elder venture]

i look down with dissapointment to new people who willingly bought a zwo camera and didnt buy the P1/touptek counterpart

ive saved a few people from the asiair spiral

[teal sandal]

ZWO makes great equipment but its overpriced and i dont like their closed asiair ecosystem

[elder venture]

Great is an overstatement

their cams are average

the red metallic finish is drippy as flip though

[elder venture]

the cygnus app on NINA makes advising against it so much easier lol

[teal sandal]

yes it is

[teal sandal]

what cygnus app

[elder venture]

oh you dont know

[teal sandal]

touch n stars

?

[elder venture]

AsiAir but for NINA

[elder venture]

nah a new one

[teal sandal]

wtfff

tell me more

[elder venture]

is it free? yes
can you use it right now? yes

[elder venture]

download advanced API plugin and the app on your phone and youre set

[teal sandal]

Does it work on IOS?

[elder venture]

when NINA is open on your laptop, the app recognizes that and builds this connection;

Phone -> Home Wifi -> PC

[elder venture]

yes

[teal sandal]

dude

game changer

[elder venture]

so basically you can control your rig from your literal BED

provided your PC and phone are on the same network

[teal sandal]

ive been thinking of buying a touchscreen for my minipc to imitate controlling from a phone or something but this is a gamechanger

[elder venture]

this also means you can literally control 99% of your setup from INSIDE the house

[teal sandal]

can i use the network my remote desktop creates

[elder venture]

i dont know lol

[teal sandal]

ill try\

[elder venture]

but i dont think nina cares

network is network

[teal sandal]

yes true

[elder venture]

https://tenor.com/view/meme-gif-20591327

[teal sandal]

thanks for this info man

i needed this stuff for my future setup

[elder venture]

NINA is the GOAT

[teal sandal]

it is

[elder venture]

spread the word

[rugged knoll]

whats it called

i dont see anything if i just search cygnus

[elder venture]

cygnus astro

[rugged knoll]

still dont see it

it showed an astrology app instead

[rugged knoll]

is it ios only

[elder venture]

nawr its on google play as well iirc

[rugged knoll]

ig my phones too old then

im on android 13

s20+

[elder venture]

do you know how to put apps on yo phone using apk files
if so
https://drive.google.com/file/d/1hpHNIsWhp_6wkB-OfmWBAh4ZZRiMK_mw/view?pli=1

[rugged knoll]

i dont

[rugged knoll]

real

mars is SUCH a pain

the right one looks like it has a bit more detail to me but the edges are terrible

[lyric dome]

@rugged knoll is the moonlight gonna effect my Saturn photo?

[woven tundra]

No

Only the clouds will

Also that wind might make your mount wobbly

[elder venture]

vro

[lyric dome]

Mars small

I got crazy data

On Saturn

Let’s go

[elder venture]

yoo

[lyric dome]

upgrade from this right?

[elder venture]

hell yeah

what equipment

[lyric dome]

Thanks

150p skywatcher, asi715, Celestron 2x

30k frames stacked

[elder venture]

not bad

[lyric dome]

thanks, need to learn to process better

[elder venture]

hold up

i think you captured a transit

[candid flare]

[ruby compass]

Hard to when bro is getting detail with uv/ir cut and I cant even get detail with ir pass😭

[elder venture]

What equipment

[ruby compass]

8" dob, zwo 224mc and celestron xcel lx 3x barlow

However my tracking didnt work and it was 3° above horizion

[elder venture]

Okay you cant compare a C11 with a 585 on tracking and good seeing with that lol

[lyric dome]

im aware lol

[elder venture]

theyre not common nor simple to capture afaik

[lyric dome]

yeah it was on purpose

[dense burrow]

which moon is that? titan?

[lyric dome]

@somber stratus any chance you could process this data? just dont crop it at all?

i like this process too

[elder venture]

Just a quick one

You captured a moon again, nice

[lyric dome]

i captured a few yeah

https://drive.google.com/file/d/15pExsvT0M5VSzkuhTx-ymY5TKNEroDeu/view?usp=sharing

[ruby compass]

Yeah.

[lyric dome]

@white yoke

[low oar]

Nice

[white yoke]

That's me

[woven kite]

Saturn and titan with my seestar😁

[zenith nimbus]

Stellarium free ahh

[ruby compass]

Luna from yesterday (20° above horizon)

[ruby compass]

LMAO

[summer pebble]

titan shadow transit
i need more data but ended up being ambushed by clouds

[low oar]

Nice though

[somber stratus]

3? lol

[low oar]

😭

[lyric dome]

Fuckkkkk I wish I got this

[lyric dome]

Just posted these on Instagram, the transit would have been so much better

[low oar]

The next transit is on my bday

[ruby compass]

Yeah

[ruby compass]

Also Tom what do you think about my moon from yesterday? (15° above horizon)

Vey cool line

vs google moon

[low oar]

@somber stratus how do I pick the correct ir filter?

[sour cradle]

there arent that many different types to pick from

a 685 is bright but you lose out on the ability to treat it output like mono on an osc cam, and its a bit less of seeing benefit
a 850 is dimmer, better seeing, notably worse diffraction, can treat like mono on most oscs
890 is a unique narrowband for some planets, revealing methane
1um is used for venus nightside

[somber stratus]

Highly dependent on gear and conditions.

[low oar]

Uranus C

What do you use with ur Uranus c

[somber stratus]

I don't. I use mono cameras for my IR stuff

[low oar]

I seee

So it would be pointless for me?

[somber stratus]

with the exception of Venus NS, but I will be using the Uranus-M for that now too.

Not pointless, just less useful. You're limited to using the longer wavelength filters, IR850 pass and 889/20 CH4 are your only (efficient) options with OSC due to the bayer matrix transparency

[somber stratus]

see above^

[low oar]

And osc stands for?

[somber stratus]

one-shot-colour

[low oar]

I see

[sour cradle]

osc, like the uranus c

[low oar]

And that is what a Uranus c is

Ahh

[somber stratus]

hence the -C

[low oar]

lol yea

So I feel like I would want to pick one for just sharper results

Not to enhance planet specifics like clouds and such

[sour cradle]

your best bet then is an 850

[low oar]

Ok in which order do these have importance

Adc

Filter

And Barlow

[sour cradle]

filter should be as close to your camera as it can be, i think

[low oar]

Should I buy a good adc first or a better Barlow first or the correct filter first haha

No I know

I’m not saying order on the image train

I’m saying importance of purchase

lol

Sorry

[sour cradle]

o

yeah i mean
with filters, adc becomes a bit less important, barlow is probably most important tho depending on your setup

[low oar]

Because rn for my imaging I’ve been just doing native

Or a cheap Barlow

Yea I have a c11

Every time I use the Barlow I get ghosting on Saturn on the right side

[sour cradle]

is ur barlow out of collimation?

[low oar]

Can’t see it in the live view or in the ser but after I sharpen it pops out and ruins it

I mean I’ve collimated the best I could

On multiple occasions

[sour cradle]

nah like
did u drop ur barlow
and now its messed up

[low oar]

Shoot idk it’s cheap and sometimes I take it apart to clean it 💀

😬

[sour cradle]

....

so yeah your barlow is a wee bit screwed probably

[low oar]

Didn’t even know Barlow collimation was a thing

Sometimes the glass moves idk

[sour cradle]

everything needs collimation

[low oar]

Jeeeze

So invest in a good Barlow first you think?

[sour cradle]

yeah
probably
and dont take it apart

[low oar]

Because I know my results are good I’m not saying that but I’ve seen what the c11 can do and I feel like I can do better

[low oar]

😂

Currently my best this season

[elder venture]

Treat barlows like refracs

[elder venture]

With a C11 and a Uranus C? Yeah dude get a good barlow pwetty pwease

[low oar]

Haha

That’s what I’m saying

My potential is there

It’s just I need some puzzle pieces to fit

What’s like the best Barlow

That’s not the cost of a new telescope

[elder venture]

You don’t need an extremely professional Barlow for it to work

You should just have a functional one

So any 100 USD one should suffice

[somber stratus]

Doesn't matter for fairly wide bandpasses.

Only CH4 it might make some difference due to wavelength shift on fast systems. Best place it after/behind the barlow in this case.

[low oar]

Well I screw my uv ir cut right on my cam and it’s fine

I see a lot of people use one called powermate?

I saw one guy do really well with a Celestron

[somber stratus]

Most modern barlows that aren't awfully cheap work well. Powermate is just a (usually 4-element) telecentric barlow made by Tele Vue

[low oar]

So it’s better?

Also tom you gonna try and catch a titan transit this time around or no?

It’s worth it

[somber stratus]

Barely. I don't notice much difference.

[low oar]

Ahh I see

I could have gotten the transit this morning but just didn’t wake up 😭

Maybe I can get a Barlow before the next one

[somber stratus]

All of them aren't visible here due to a odd 'resonance' between Titan's orbital period and Earth's rotational period. Only one part of Earth gets to see them for an entire season. This equinox it's NA/SA.

[low oar]

Woah shoot dude

I had no clue

That’s insane

That’s like actually crazy how that works

[somber stratus]

Literally not visible anywhere else. I think the 2040 series is better placed for us.

maybe

[low oar]

I don’t understand but it’s crazy haha

[somber stratus]

It's all coincidence. No causal relationship

[sour cradle]

so we are safe from u specifically in the category of titan transits

[low oar]

Haha

How does that work though that doesn’t make sense

It’s a billion miles away

And a shadow

How is it not visible

Or is it just light out when it’s happening or something

[somber stratus]

Just the orbital period is a multiple of earth days. Just coincidence

like how Jupiter's inner 3 moons have roughly the same position every 7 days.

[low oar]

Oh

[somber stratus]

15.95d to be exact, but that 0.05 drift is countered by the fact Saturn rises earlier and earlier due to Earth's orbit around the Sun.

[low oar]

I sure I could understand if there was a picture 😂

Thanks for attempting to explain though

But you got it in 2040

A Solar Eclipse 1 Billion Miles Away! 🪐

This morning on June 2nd I was lucky enough to image Saturn and its largest moon Titan, Titan was casting its shadow on to the surface of the gas giant! 📸

This is the best I could do on the last one

Hopefully I get the one on my bday

[thick heron]

Shadows are well-placed for me again in 2039. Thank goodness, I'll need it at this rate.

[somber stratus]

Yeah, checked it just now. 2039 is also shit for us

then 2054 is good for Asia.

gg

[thick heron]

You've got some time to move.

Group-buy a 32" HO and ship it to Barbados.

[elder venture]

I am so certain the solar system has beef with Europe

[low oar]

😂

That’s unfortunate though

[somber stratus]

Soon ™

[woven kite]

How often are titan transits

I was awake but i didnt feel like moving anything

UNTIL 2040?….?

[low oar]

Depending on where you live I guess

But yea

They come in periods

We are in one rn for certain areas

[somber stratus]

Last one of this stretch is late this year. After that, you'll be waiting until 2039

Only happen near and around Saturnian equinox (~15 years).

[woven kite]

Ill be 34

[somber stratus]

Solar system for ya

You'll be lucky if Neptune does half an orbit during your entire lifetime

[woven kite]

Thats crazy

Ill live to 83

[elder venture]

[low oar]

dang powermate 2x is expensive

[thick heron]

Doesn't have to be Tele Vue to be good.

[somber stratus]

yup

In my case I just have it as it's one of the few that can reach focus, and it puts me in the correct FL range

[ruby compass]

Btw the Barlow u recomended has been working great! Thanks

[sterile marsh]

Thats the one i have but mono

[teal sandal]

Has anyone here attempted cloud details on Neptune

I saw this

[sour cradle]

tom prob got surface details on neptune

[thick heron]

I've gotten them.

Only way I would consider valid is with a time-lapse except possibly in exceptional circumstances. Hard to distinguish from artifacts otherwise.

This was with the EdgeHD 14.

[terse night]

What software do you use to add the time/info?

[terse night]

Oh damn. Yeah I ain't getting shit with the C8 then

[thick heron]

Affinity Photo

[white prawn]

Neptune would likely be a little over half the size of that with Rio then.

[white prawn]

There a free equivalent or am I fine to keep using Gimp?

[thick heron]

GIMP is the free equivalent.

Krita too but think that's geared more towards art than photo manipulation.

[lyric dome]

Ethan that’s crazy you can see Neptune

With good seeing and a 6 inch and a good 2x Barlow at 1500 focal length total could I detect it?

[somber stratus]

Easily. It's only mag +8

[elder venture]

You can detect it very easily

only issue is actually imaging it

its a blurry circle

[thick heron]

I accidentally found it a couple weeks ago.

It's next to Saturn.

[lyric dome]

How many pixels could I get like could I image it?

The only 2 planets I haven’t imaged are mercury and Neptune

Go figure

My pixel size is 1.45

Microns

At 1500 focal length

Asi715mc

[elder venture]

It’s like 2.2 arcseconds wide so

You can use telescopius to figure out how many arcseconds you get per pixel with zat

[lyric dome]

I have no idea how to do that but

Oh damn

11 pixels wide…

That’s pretty damn small

[low oar]

The only planet I need left is Neptune

[ruby compass]

Okay. Wth.

[teal sandal]

hm yeah i can see there are quite a lot of artefacts

timelapse helps

did you use any filters or just color rgb imaging?

[ruby compass]

Would assume uv/ircut

[lyric dome]

Right???

[white prawn]

Centered on something else?

I think there's a speck or something in the band on the first image ... which happens to be at ... about the center of the image.

[lyric dome]

interesting

that sucks

thatll work for now, going to film saturn again tonight

[rain mauve]

kinda sad i cannot get this kind of result

: (

this is what i can get max

[lyric dome]

Yooo this looks exactly like mine earlier this year, whats your focal length?

[rain mauve]

native 900mm

but i use 1800mm and dslr camera

and software and use the 5x live view magnification

collected like 5k frames and stack them

[lyric dome]

whats your framerate?

[rain mauve]

30 fps

sometimes drop like 27

[lyric dome]

Make you frame rate 8ms per frame

Roughly

5-12 somewhere in these

[rain mauve]

8ms?

[lyric dome]

And try going for like 20k frames

This is my test saturn using a cheap 2x on top of an expensive 2x, mimicking a 4x at 3000 FL, my scopes normal focal length is 750

[lyric dome]

8ms per frame

[lyric dome]

Clearly the cheap 2x is holding me back, im gonna buy a 4x soon

[rain mauve]

this is fine

[lyric dome]

yeah but it has some blur

i cant sharpen much or it looks odd

[rain mauve]

wait 1ms perframe how much it is?

[lyric dome]

i meant 8

thats what i do

Im off to process more data from today

[rain mauve]

my iso is 3200 and i use 1/80

1/80 its dim already in my telescope haha

[lyric dome]

i dont use a dslr so idk whar that means

[rain mauve]

ahh you use like color camera?

rip might be to get 1 of those

[lyric dome]

I use an Astro camera

An ASI

They are built for telescopes only

[rain mauve]

uranus c is good?

[lyric dome]

YES DUDE THE BEST

if you get one of those you are golden

I can’t afford one

I have an asi715mc

Cheap one

[lyric dome]

@somber stratus @livid sierra is it worth trying to shoot Jupiter just to shoot it at 27 degrees?

[shell epoch]

At that angle I believe you are shooting through 2.2 atmospheres, and at 20 degrees it goes to 2.9. If you want to, you should go ahead.
You could also just get rid of the blue channel and replace it with half of the red and green channel. Or mess around with ir imaging

[lyric dome]

I shoot in RGGB, is there a way to separate the colors?

I think there is on registax rught

However I don’t know how to replace it per say

[shell epoch]

Yes

Siril

You can separate the channels then use color math to recombine them

Make sure the debayer option is deselect when you select the image, or siril won't recombine the channels and give an error message

https://m.youtube.com/watch?v=XElPHYbysIA&pp=ygUQU2lyaWwgY29sb3IgbWF0aA%3D%3D

[low oar]

seperate color?

anytime i do a image i make 2 layers in photoshop

one detail and 1 color

and seperate them

[lyric dome]

I have no idea haha

[lyric dome]

Assuming I even find Jupiter tmr morning…. Will you do it for me?

[low oar]

finally jupiter is coming back

[lyric dome]

I mean sorta

It’s in the same situation that Saturn was 2 months ago yk

[shell epoch]

I cant, sorry. But it's not hard to do. And it's optional so you don't have to

[shell epoch]

Yea! I can't wait to start imaging it again

And I'll give a try for Uranus too

Although I know it won't be much, I still want to check it off the list of planets I've captured

[elder venture]

jupiter top 10 overrated targets

[native plume]

whats an underrated target

[elder venture]

Uranus

[native plume]

whats your top 5 underrated targets

[elder venture]

Uranus
The Hidden Galaxy (C5)

🤯

[ruby compass]

Yooo! Could someone please derotate my saturn data?

(each image)

(one of the files)

[rain mauve]

this is my sharpest saturn's pic from DSLR and 80mm diameter telescope

What can i improve to make it better?

[lyric dome]

Do you have a high quality 2x Barlow?

[lyric dome]

80mm is so small this is really good for it

[rain mauve]

I use Barlow already

Bought cheap one

Omni 2x

[lyric dome]

How much was it?

[rain mauve]

The price?

I bought for 1 dollar

10 Bucks*

[lyric dome]

Oh haha

If you want better image get a better Barlow

[rain mauve]

Alright, Barlow really affect the image quality huh

Any recommend Barlow?

[lyric dome]

I don’t know what your price range is but I would get this brand

https://www.highpointscientific.com/celestron-x-cel-lx-2x-barlow-lens-1-25-93529

These are absolutely insane

They make 3x and 5x version as well

But don’t go above your theoretical max

X-Cel

[rain mauve]

Damn I gotta save money

124 bucks

[elder venture]

From a DSLR??

[elder venture]

Barlows arent that sensitive

Tbh a 50 buck one should do well enough

[rain mauve]

Yeahh

[elder venture]

Thats really good for a dslr

[rain mauve]

Woah really? Thank you

[elder venture]

Do you happen to know the Focal Length of your scope

[rain mauve]

Oh yeah forget to mention 80/900 x 2 barlow

So yeah it's 1800 mm

[elder venture]

Which DSLR do you use?

[rain mauve]

1300D canon

Like the old model one

[elder venture]

With your setup you could do a 3x barlow and get something out of it

You can go ahead and look for any local suppliers of a 3x, as long as it isnt terribly cheap it should do a lot for you

[rain mauve]

I see

Thank you for the infromation

What brand do u recommend?

[elder venture]

To calculate which barlow makes sense to use, use this formula;

( pixel size x seeing value ) / Focal Ratio (Focal Length / Aperture)

Seeing Values are;
Bad Seeing = 5
Good Seeing = 6
Excellent Seeing = 7

[elder venture]

Not any in particular.

of course the celestron ones are nice but you can go with off-brand ones like from GSO

Just dont buy any under 20 USD

[rain mauve]

How to check the seeing value?

[rain mauve]

Alright thanks

[low oar]

Why can’t you?

[untold spear]

Svbony 2x Telecentric is actually pretty good to start

[ruby compass]

Idk how to derotate

[low oar]

It’s like

The easiest thing

Just learn it

[ruby compass]

could u do it this time?

cuz i dont habe time to learn that rn

[low oar]

It takes no joke

5 minutes

And no 😂

[ruby compass]

alr

[elder venture]

Seeing is by your own judgement

If you can see VERY far, you have excellent seeing.

If its average, then its "good/ok" seeing.

If its bad, like foggy, then its well, bad.

[low oar]

Like Tom’s version of good seeing is our version of perfect seeing

[livid sierra]

You are confusing seeing with transparency.

[elder venture]

Zats how i was explained to find out how good seeing is lol

couldnt actually test it yet and didnt have any incentive to

[livid sierra]

This is what is meant when talking about seeing.

https://youtu.be/w-2F3Db6HKg?si=D1X_FoG87qiUSBss

[rain mauve]

Ohh ok ok alright thanks

[rain mauve]

Ok ok

Thanks

[rain mauve]

So much difference

Is it not recommend shooting Planetary with very low in horizon?

[elder venture]

It is not

Air is denser and light pollution is worse

[low oar]

I wouldn’t but if there is a cool event like a transit or something go for it

No stopping you

[somber stratus]

Ah yes "Jupiter"

[somber stratus]

Light pollution

[somber stratus]

Meh, I like the challenge, even without a transit. All of my Saturn images are sub-35°

mostly due to my latitude, so not out of choice unfortunately

[low oar]

Fair

[thick heron]

I'll go for it regardless in the early or late stage of an apparition.

[somber stratus]

that too

Though I'm notoriously bad at the late stage.

[thick heron]

Not with Uranus and Neptune.

And never pushed it with Venus but probably should.

Mercury is begging for a revisit after 5 years.

Pluto and Charon need a visit too.

[elder venture]

can you even resolve the difference

[thick heron]

Charon has been seen with a 14".

It doesn't split off but it's there.

https://x.com/TerryLovejoy66/status/1320523551347101697

Terry Lovejoy (@TerryLovejoy66)

This is the most convincing detection I obtained of Pluto's moon Charon so far. This was on Oct 2, 2020 (best seeing out of 7 nights). @Celestron C14 + Olympus omd em1mk2 + Skywatcher EQ-RH from my suburban observatory in Brisbane, Australia.

X · Oct 26, 2020, 12:32 AM

[somber stratus]

Other stars being elongated

[thick heron]

They aren't nearly as elongated.

Max separation is 0.8".

[low oar]

Jeeze

Could a c11 and Uranus c do that?

[thick heron]

Would like to give it a shot for six days straight. Hard to doubt if you can see them orbiting.

https://x.com/TerryLovejoy66/status/1312209989436542976

Terry Lovejoy (@TerryLovejoy66)

Closest I've got to a detection of Pluto's moon Charon with C14 and digicam (Olympus OMD EM1mk2). Only 0.8 asec apart, mag 14 & 16. I think I can see a bump in the right direction for Charon. Chart from Guide 9.1 below shows field stars and locations of Pluto/Charon.

[terse night]

Light pollution doesn't really matter

The one image I have of Saturn was shot when the sky was bright blue after sun rise lol

[elder venture]

right i forgor

[elder venture]

with perfect conditions i would believe so

it should have the resolving power to do so

[terse night]

Btw @somber stratus I have a question. So recently I tried planetary for the first time (yeah I know, I have a C8 and i never did planetary with it ) and I got this. Saturn was decently low, I believe 30° or so, and seeing was quite bad. I notice a weird artifact on top, it looks like the planet is "doubled". Could this be the really bad seeing splitting the colours so much that they land on different pixels?

This is luminance

This is not a sharpening or stacking artifact as I can kinda see the same thing in the raw video. I'll send that too in a moment.

[thick heron]

Likely dispersion.

This is where an ADC comes in handy.

[somber stratus]

what Ethan said

small chance is astigmatism from poor collimation but much more likely a lack of an ADC

[thick heron]

Also, are you imaging with a diagonal?

[somber stratus]

Depends if "horizontal" here is aligned with the horizon as to whether it's dispersion or not.

[thick heron]

I can tell from the ring shadow it's mirrored. If so, no need for it unless there's a clearance issue.

Oh nevermind.

Guess who forgot which way the rings are tilted?

[low oar]

💀

[somber stratus]

[low oar]

Stuck in 2019

[somber stratus]

stuck in 2024

[low oar]

lol

[thick heron]

It's been 12 years. This is a strange new world.

[low oar]

Tom

How much money

Have you spent on this hobby

Estimated

[terse night]

Yeah, shooting the individual RGB channels helps with that right?

[thick heron]

You know how you might accidentally write the previous year for a couple weeks after new year's day? This is me with Saturn right now.

[terse night]

Collimation is fine

[terse night]

Considering the images he gets, the right amount

[thick heron]

Will be less but not gone entirely without an ADC.

[terse night]

Is the zwo one alright?

[somber stratus]

Gear is worth more than what I've spent on it due to finding good deals, but I've actually spent probably in the ballpark of 12.5k, with a good chunk of that being financed from APY winnings over the years.

[low oar]

Apy?

[somber stratus]

Astronomy Photographer of the Year

[low oar]

Woah what

Where’s that

That’s pretty cool

And you got paid cuz your the best?

[somber stratus]

Yearly international competition run by Royal Museums Greenwich in London. They have an exhibition of all the shortlisted images.

[low oar]

Oh jee3

Jeeze

[somber stratus]

You get prize money for 3rd,2nd,1st in each category

[low oar]

I ain’t a Londoner

[somber stratus]

International enteries, it's just the physical exhibition is in London

[low oar]

Ohhhh

Very nice

But won’t the best of the best continue to win each year

[somber stratus]

Ethan has won a fair few prizes over the years too and he's in the states

[low oar]

Woah

[somber stratus]

In theory, probably.

[low oar]

Ah

So I gotta pop

[somber stratus]

but you have to be unique. It's not as simple as "take a high res image"

[low oar]

What if I take the clearest pic ever of the moon or something would that do well how does it work

😂

I seee lol

[somber stratus]

https://www.rmg.co.uk/whats-on/astronomy-photographer-year/galleries/overall-winners-2024

click on these green tabs to show all images in each category

[low oar]

Wow ok

So 1st place pays a lot?

[terse night]

I don't even understand the image completely lol

[low oar]

Is there a grand winner?

[terse night]

The orientation was something like this

[somber stratus]

Yeah. £10k for overall win, and in each category: £1.5k for win, £500 for 2nd, £250 for third.

[somber stratus]

Hmm then probably not dispersion.

Could be anything really.

Collimation, barlow optics playing up, diagonal (if you used one)..

[terse night]

The barlow could definitely be one of the issues. Another user here had a similar issue and apparently it was internal reflections. Flocking the barlow seems to have helped.

Thanks for the help, I'll try narrowing down the possibilities till I find the cause

[lyric dome]

Agree to disagree lol

[elder venture]

you dont need a terribly expensive one lol

buying a 123 USD one is a wast eof money in my eyes

They need to be properly assembled and use proper optics but thats all

[lyric dome]

I mean I guess you don’t NEED, but I’ve used a 59$ one and the 123$ one I bought is much much better

In my experience atleast

I guess it depends what defines terribly expensive as well

[elder venture]

you still need to watch out what you buy

often times theyre either cheap china shit or just no-brand stuff

[lyric dome]

For sure

Yup

[elder venture]

like GSO and Omegon are the exact same just for different distributors

[lyric dome]

I try to only buy from Celestron or skywatcher but

ASI as well

[elder venture]

[lyric dome]

Haha

That’s where I got my IR/uv cut filter

It was 25$

And works perfectly

[elder venture]

zwo makes incredibly mid products for a premium price

and the company just SUCKS

[low oar]

Holy, is there a lot of competition though?

[lyric dome]

Is someone mad they raised prices because of American tariffs?

It’s hard to know if that’s true or not soully based on 1 person

[lyric dome]

Fine then, give me the best planetary camera you know of? I’m guessing you’ll say Uranus-c or an Ares-c

On another note @somber stratus any advice for how to process lots and lots of images when making a timelaps for planetary rotation? You already gave me the python code to correct field rotation, however my next issue is I feel like I’m not mass processing the images to there full potential, the limiting factor being that you want every image to look similar, tell me what you think please

[elder venture]

The best planetary camera?

Based on what?

Price to Performance ratio?

[elder venture]

Im not American

[elder venture]

A personal favourite of mine the mars c II, otherwise the asi678mm is very nice too but well, it’s zwo

And you’re right the Uranus C is a godtier pick as well

[elder venture]

-.- let me get the message

[lyric dome]

No period

[lyric dome]

It doesn’t tell me who sent the message, and it’s still opinion based if it’s 1 person

I’m a single person too so there is no reason for me to think it’s great either, however my cheap 199$ camera works wonders for me

Personally

I don’t see 200$ cameras from other company’s doing as well

If so I would have bought that one

I like my tiny ass 1.45 pixels 😂

[elder venture]

Sensor isn’t as popular

Zwo is generally a horrible company which you yourself can check by just researching

If they have cams with sensors you need and no other one has it so be it

[lyric dome]

I mean I like smaller pixels personally but im not educated on the subject, so it’s hard to know what to and what to not buy, especially if you were going to invest a lot of money, half the people say something is good and half the people say it’s bad

[elder venture]

Mmmm would have to be the Uranus-C due to its insane sensitivity in the proper lines

[lyric dome]

Cool

Those are like 2k tho right?

[elder venture]

What

[lyric dome]

Uranas-c

[elder venture]

The Uranus C costs like 360 USD

[lyric dome]

What?

[elder venture]

Where did you get 2k from

[lyric dome]

On what?

I looked it up last year

Said 1999

[elder venture]

Their own website lol

[lyric dome]

Send me a link rn 😭

[elder venture]

Just go onto player one astronomy

And go to planetary cams

It’s not that hard lolol

The TEC cooled version costs like 550 usd

[lyric dome]

Is it worth the money for planetary?

[elder venture]

Oh it’s awesome

Tom uses it

The cooled version is more for DSO

The uncooled does plenty for the price

[lyric dome]

I mean the cooling one

Vs not

[elder venture]

For planets, it’s not worth it.

[lyric dome]

Got it

[elder venture]

Thermal Noise only really is relevant when it comes to DSO

[elder venture]

Also the ACS they promote also is not worth it

Not because of planets but because it’s generally shit lolol

[lyric dome]

What is?

What’s an acs?

[elder venture]

They promote a fan cooler

[lyric dome]

Ahh

[elder venture]

Active Cooling System

[lyric dome]

Do you do plantary?

[elder venture]

I did a bit with my dslr, rn I’m waiting on my Neptune-664C to arrive

Im well versed in the topic but just lack physical experience

[lyric dome]

Gotcha

Would you say it’s worth the money to buy the ura-C when I already have an asi715mc, for my setup 6 inch reflector 750mm, OR keep saving for my 10 or 12 inch and get one faster? I’m thinking it might be worth getting it now because once I have a bigger scope I’ll want it anyways but lmk?

[elder venture]

For purely plants yours should suffice

[lyric dome]

Cool

So it’s not worth the money?

[elder venture]

It is worth the money but you have a totally functional and by no means bad camera at your disposal

[lyric dome]

Gotcha

So you hate on the company not the cameras?

[elder venture]

The cams are by no means bad but

Just mid for what you pay yk

They’re insanely average

[lyric dome]

Yeah

[somber stratus]

Of course. Arguably the biggest in the world for AP, they had 6000 entrants this year. There is a similar competition for wildlife photography iirc too

[somber stratus]

Batch process in Astrosurface

That’s how I do the timelapses

[lyric dome]

How do you do that? I look it up on YouTube.

I will*

[somber stratus]

Fairly simple. Open one of your images, go to wavelets-decon tab and choose the wavelets you want to apply. Then “save p” for saving the process. Then exit and go to batch>wavelets decon and load up the process/batch of images you want to process there

[lyric dome]

Thanks, Tom

[low oar]

Was I wrong when I saw the winner was a simple picture of the moon?

[lyric dome]

idek what i did

[low oar]

Nice dude

[lyric dome]

Hey man you got ISS?

[untold spear]

Wait, there's a python code? Can I have it to try?

[untold spear]

Everything China except the scope

[elder venture]

China Products ≠ Cheap China Shit

Cheap China Shit are those 50 buck junior telescopes

[untold spear]

I thought some of you guys think Svbony is conaidered "China shit"

[ruby compass]

Example of extremly horrible seeing😭🙏🏻 (5Arc/s)

[ruby compass]

I love Svbonys filters

[sour cradle]

theyre svbony
theyre okay

[untold spear]

Yeah I actually used their UV IR Cut and Telecentric Lens

I tried comparing with my old GSO 2.5x, turns out my Svbony did better job

[untold spear]

Is this current Jupiter? It's already high in my place but sadly the tropical weather hit me

[somber stratus]

Looks a touch out of focus, but still diabolical

If you rack the focuser outwards slightly, you bring the upper atmosphere (i.e jet stream) into focus so the ripples appear more defined.

[white prawn]

As long as you don't get the bottom level economy stuff. Looking at the SV105

[white prawn]

"What are you imaging?"

"The jet stream. Frickin' Jupiter got in the way."

[somber stratus]

Wait until they find out that all sensors are the same for P1/ZWO/QHY/Svbony. The manufacturers just add the camera body and RAM buffer.

[elder venture]

Firmware as well no?

The Specs are slightly different across companies I’ve noticed

ToupTek has a lower full well than P1

[low oar]

Hm?

[lyric dome]

Have you captured the ISS yet?

[low oar]

Yea

@lyric dome here

[untold spear]

585 sensor 👀

[lyric dome]

Awesome dude, how do you know when it’s gonna be a bright Passover?

[low oar]

stellarium

on your phone

[low oar]

then you just gotta track it

[lyric dome]

Okay, and how bright should I want it to be?

[low oar]

What?

[lyric dome]

Tellurium will tell you the magnitude, how bright should I want it

[terse night]

It just needs to be illuminated by the sun

It's going to be around the -1 / -3 range I assume

[lyric dome]

Gotcha

Cook

Cool

[low oar]

Your exposure has to be really low

The ISS gets insanely bright

Look at it pass Saturn

It’s still bright and look how dim Saturn is

[lyric dome]

Crazy

[woven kite]

processed image gonna look like one of those round ceiling lamps

[ruby compass]

It wasnt out of focus. Seeing was just stupid. (It was no joke 55° above horizon)

[ruby compass]

I tried. U can make out the 2 bands but thats about it😭

[thick heron]

I agree with Tom that Jupiter is out of focus and the atmosphere is in focus. See the same thing all the time in winter.

[rain mauve]

Saturn with my. Phone

With 4 mm eye piece

Celestron 80Eq 80/900mm
With infinix note 50 pro

[low oar]

nice

[rain mauve]

Thanks!

How to get rid the halo thing in the Saturn edge?

[low oar]

i have the problem too

Especially when i use my barlow

[lyric dome]

That’s honestly the best iPhone start I have EVER seen

[lyric dome]

Likely due to not being collimated well

[elder venture]

Multiple possible causes;

Atmospheric Dispersion
Out of Collimation (fixable)
Bad Barlow (fixable)

[lyric dome]

I personally feel like even with atmospheric dispersion the stacking program won’t stack really bad frames so I don’t think it would be there, but the rest I’d agree with

[stuck basin]

Earth Astrophysics is new to me, how was this done?

[fading plume]

The satellite broadcasts images every 10 minutes. All you need is a satellite dish, SDR and a computer to receive and decode it.

[stuck basin]

It almost looks like the same picture but I didn’t get as long video time

But we both have a werid green effect and color shift

Just how long is that focal length is on that scope? It must have a huge apture to have that much small details

[low oar]

I think I’m gonna try Saturn in the morning

[fading plume]

Sorry it’s a 10”

And 3x barlow

It’s 1200mm native

[lyric dome]

Is this worth trying to shoot? I’m getting really bored with ap and want one thing to do

Or what time during sunset can you start to see mars?

[fading plume]

What’s its apparent size? Isn’t it way outta season rn? I’ve been out of the planetary loop for a while.

[lyric dome]

Honesty have no idea, that’s why I’m asking, I haven’t tried for mars in forever

[fading plume]

It’s somewhat close to the sun so probably tiny

[lyric dome]

A shame

4.5 I think

Arcseconds

Yeah that’s tiny even for my setup

[fading plume]

Saturn is really the only major one I’d bother with.

[lyric dome]

Yep, a shame

[somber stratus]

Venus is reasonable for northerners

and Jupiter soon to return

[fading plume]

Or just shoot DSOs like a normal person

[somber stratus]

[thick heron]

Soon to return?

[low oar]

I would say to small for most people

[lyric dome]

I could capture it, but my dark site is blocked on the direction by trees

[sour cradle]

i could go venus
but ill prob fail again

[low oar]

Yea I recently got Venus

Saturn in the morning, Venus in the morning and soon Jupiter in the korning

[lyric dome]

May I see?

[untold spear]

Jupiter 23 Jul

[lyric dome]

Not bad, how high was it?

[untold spear]

around 12 deg

[lyric dome]

Uhm, that was last year?

Today is the 22nd

[low oar]

lol

[untold spear]

sorry I live in asia

[untold spear]

yeah it's 22nd

[untold spear]

this year

[lyric dome]

Oversampled?

[low oar]

Uh idk

It was full frame lol

[lyric dome]

Damn probably then

[low oar]

I think I probably stacked 3-5% of 40k

[lyric dome]

Gotcha

[low oar]

2 minutes of data or something

[lyric dome]

Damn

[low oar]

Prob 2:30

Gonna use my telescope for the first time since the ISS Saturn transit

[rain mauve]

Hmmm ok ok, my Telescope used to be fell of, idk bout that

[rain mauve]

Thanks haha

[lyric dome]

You like the pfp?

[rain mauve]

Red Mars??

Jupiter with ring?

Lmao, yeah that's good

[lyric dome]

Lunar eclipse moon 😭

[rain mauve]

Haha

[heavy mirage]

That's a 10" scope at 1200mm native. I typically shoot planets at 5400mm.

If I understand correctly the green effect you're talking about is both due to shooting in raw mode without any color correction as well as atmospheric dispersion maybe some CA.

[lyric dome]

Yes, you need an ir cut filter

Hey, @somber stratus, have even captured a Dione eclipse on Saturn?

On another note, do you ever just go out and look at things visually?

[untold spear]

I'm not sure if it's visible due to discord compression

[untold spear]

27/9/2024

Had to oversharpen a bit

[lyric dome]

Oh awesome dude

[lyric dome]

What scope do you have?

[native plume]

yoo ur malaysian too? also nice image with the 8"

[untold spear]

Skywatcher Flextube 200p

[untold spear]

Ain't no way I found another malaysian here

[rain mauve]

Im at equator too haha

[teal sandal]

What IR filter is the best for fighting bad seeing? And not being too dark?

I was thinking of getting an IR850 or something like this, could also be useful for Venus clouds

[terse night]

It depends on the qe of your sensor

[teal sandal]

I have imx 664 color, I will also have imx462 mono in the future

[ruby compass]

685

[teal sandal]

Will it help with resolving Venus clouds too?

[ruby compass]

Yeah

[teal sandal]

Nice

I’ll get it, will be useful for guiding too

Thanks

[ruby compass]

I have it and it works awsome

[summer pebble]

saturn tonight

[untold spear]

this morning, my IR data seems useless to make as (L)RGB

Compared to my two nights ago

[teal sandal]

I wonder how did Jupiter change by now

And did the GRS shrink

Cuz in my months long timelapses it has been slowly shrinking

[elder venture]

jupiter without GRS would be like

saturn without rings

or venus without clouds

[thick heron]

Someone with a deep archive of Jupiter images should work on that.

[terse night]

Yes it's shrinking

[teal sandal]

Seeing Venusian surface would be very cool

Probably lots of stuff happening there

[teal sandal]

Did it load as a gif?

I’m sending from iPhone

[terse night]

Yes

[teal sandal]

Nice yay

I wonder by what year will grs be gone and will we see new storms like this forming

[elder venture]

You can see it tho

Thermal Vision is weird

[teal sandal]

With 1010nm filter?

I don’t think I can image with it on my mak😔

Gotta wait for a big dob

Soon ™

Wow this is very cool

24 inch dob and iNova PLa-Mx camera

First time hearing abt this camera

Sony ICX618ALA ccd

[teal sandal]

im thinking of combining w47 and NPZ SZS-22 for venus clouds imaging, is this a good combo? Or should i buy a ZWB2 filter?

[stuck basin]

Re-edited my Saturn and Jupiter and got a little bit more detailed but only slightly and fixed the colors a little better because the original images were green

You can still see the green with Saturn a little

Both those images were originally captured over a year ago but tonight I’m going to try to get Saturn again but with more video time but it’s lower on the horizon so I have no idea how it’s gonna turn out

[olive saddle]

If it's any consolation, iirc Jupiter's red storm is constricting because it's intensifying, and the winds are getting faster. It could deintensify at some point, and the eyewall of the storm would expand again, potentially making the red spot larger.

This does also bring up the potential that the storm dissipates too intensely, and loses all structure entirely, which would be sad to see.

[rain mauve]

yesterday saturn, phone with 4mm eyepiece and telescope 80eq, seeing was poor

[low oar]

with a phone thats very nice man

[rain mauve]

Thank youu

I'll be invest on good Barlow lens soon, or maybe buy an astro cam?

Like Uranus C

[white prawn]

If you can do only one, Barlow.

Best do both. Though if you're good with the phone you might be able to do some interesting stuff. I was never able to capture anything of decent quality on my phone. I got a couple of shots of Saturn and Jupiter was just a bright ball of light no matter what I did.

[low oar]

I have that

[rain mauve]

Ok ok

Thank you very much

[rain mauve]

Wow, thats great

[teal sandal]

Oh I didn’t know that

Interesting interesting

[stuck basin]

How did you stack it good?

I’m very bad at stacking

I’m trying to stack a picture of Saturn rn

[rain mauve]

I use autostakkert to stack it tho

[stuck basin]

What settings did you use?

[rain mauve]

But before you do the stacking process, you need pipp to align it, chose Planetary option,(i shot the Saturn with iso 6400 and 1/60 30 fps
Record max 2 Minutes
Import to pipp
Check Planetary option
Then to the processing option
Choose stretch to 50 percent or something
Crop AS you like(444x444) usually will do the job
Then import it AS avi uncompress
Import the avi files to autostakkert
Analayse it
So you want to see the graphs that show, check the RGB align, there are 4 empty, write it 80 50 35 and 20, place ap grid, make sure it's not too small(idk for some cases it creates weird stacks artifact)
Then do the stack, and... see which the best frame you consider. Process it into registax, sharpened it, and your done

That's my workflow, idk about the others, other perhaps will do more professional than me
