The moon rising tonight

[woven kite]

😭

[graceful creek]

i feel like they are posting different galaxy

[keen hornet]

𓎼𓂋𓎼

𒅴𒄩𒌈

22° Moon Halo

[rain mauve]

Lol even rami astro footage got stolen

[winter moat]

Noice

[graceful creek]

i wonder if halo can be of different angle

[winter moat]

with my phone

[keen hornet]

I captured this one last year

[keen hornet]

The moon was setting at that time. So...

[native plume]

thought that was the sun

[keen hornet]

Haha

[low oar]

Peak

[ruby compass]

How did u do this?

[low oar]

24 inches of glass that’s how

[ruby compass]

I mean cuz acording to stellarium-web.org it stays tidaly locked to us

[low oar]

look at the app, and change the months, it moves ever so slightly

its tidaly locked to jupiter

not us

and jupiter orbits the sun

so we get to see different angles of its moons

[terse night]

Sure

[main flume]

okki :3

[ruby compass]

I didnt see any differance tgo

Tho*

Even over a year

[quick cairn]

I think it has to do with its huge orbit

[ruby compass]

Okay it does but It took like 7 years for one rotation..

Dont think tom spent 7 years to make the image

[ruby compass]

Yeah but 7 years for 1 rotation

[quick cairn]

Maybe I misunderstood what titly locked means but I think a few images while it’s far away and then really close in front and then really close behind. You can see settle differences.

[low oar]

i can screen record the changes

[ruby compass]

Ye

Dp that

Do*

[low oar]

i mean it is 7 years but 🤷‍♂️

[ruby compass]

Exactly

So how did he do it?

[low oar]

hes tom

he just did and dont question it

[glossy frigate]

Guys look😁

[ruby compass]

@somber stratus my bad for the ping but genuiently how did you do the full rotation of Ganymede?

@low oar 1 member from 25k

[low oar]

hm?

[ruby compass]

Like its at 24999 memmbers

Members

[low oar]

oh

cool

[ruby compass]

Yh

[rain mauve]

Nice oneeee

[quick cairn]

In the description of the post, did he say he combined the data with other people?

[low oar]

🤷‍♂️

[ruby compass]

Nope

[somber stratus]

It rotates from our perspective. Nothing special about it

[ruby compass]

It takes 7 years tho?

[somber stratus]

Huh

[ruby compass]

Or is stellarium wrong?

[ruby compass]

Read the convo

[somber stratus]

It rotates with a period equal to its orbital period since it’s tidally locked to Jupiter

I.e 7 days

[ruby compass]

.

[somber stratus]

But it took 2 apparitions to get sufficiently good data of all faces

That stellarium is bugged then

Mine works fine. Shows it as 7 days

[ruby compass]

Could u screen record or smt?

[somber stratus]

1 sec

[ruby compass]

Alr

[somber stratus]

also I literally captured the rotation within a single night. It's noticable over a few hours

[ruby compass]

U did?

When?

[somber stratus]

https://media.discordapp.net/attachments/933891163725914142/1013425210822766642/2022-08-28-0040_5-U-RGB-Jup_lapl6_ap16_pipp.gif

some time ago now, 2022

@low oar

[quick cairn]

Dang Brian Martin is being blasted for this one…. I don’t blame them. He may capture real data but the AI tools used are just so obviously misleading

[somber stratus]

link?

[quick cairn]

Sure thing, Tom. https://www.facebook.com/share/p/1He5Uaqv2e/?mibextid=wwXIfr

I just find it funny

[somber stratus]

Yeah I mean it's partially artificial/AI. The problem with Brian and others like him is that just because they capture the raw data, they think it's completely fine to nuke it with any and all processing under the Sun.

and in their eyes it's just as "real" because the raw data is real

[thick heron]

When will #1019937457095065731 learn about search engines?

[quick cairn]

Exactly, Tom

[ruby compass]

Dayum

[ruby compass]

U should lwk make a rotation timelapse of ganymeade

Or io would be easier

Also remake the full image now that u are better at imaging🙏🏻

[ruby compass]

Like remake this

[silent mesa]

1 hour rotation

[quick cairn]

You have some weird effects but awesome data

What’s your setup?

[silent mesa]

Yeah I don’t know why that happened

[silent mesa]

Celestron Nexstar 8se, 2x Barlow, mars-c ii, uv/ir cut filter

[graceful creek]

it looks like its a oblate spheroid

and it looks like its rotating

mmmmm

[olive saddle]

that's because Jupiter is, in fact, an oblate spheroid, and is, in fact, also rotating

wooooo, too many commas

[winter moat]

Very nice :D

[graceful creek]

i see...

is there a planet that is elongated spheroid

[winter moat]

Google it

[low oar]

😂

[olive saddle]

I believe WASP-12b is somewhat of an elongated spheroid, being distorted by its parent star that it orbits way too close to

[low oar]

🐝

[graceful creek]

OHH yeah

[ruby compass]

Firee

[quick cairn]

No

[ruby compass]

I mean vesta is like the only elongated body imageble that I can think of

[quick cairn]

But vesta doesn’t have enough mass for its own gravity to force it into a sphere

So idk if it counts as a planet

[flint siren]

Haumea is elongated too

And this time it's a dwarf planet

[flint siren]

☝️

[graceful creek]

i see

wait wrong link

https://en.wikipedia.org/wiki/Haumea

yup

uhh

a dot

[ruby compass]

Yeah?

[quick cairn]

What’s the probability that there is a object the size of Pluto or bigger in the solar system that we haven’t seen? None right?

[olive saddle]

Greater than 0, I'd say

there's always the chance that something on an absurdly elliptical orbit, much further away than Pluto, has still evaded our detection

Pluto was already extremely difficult to even detect, let alone resolve visually. Not even Hubble could get good images of it, and I doubt JWST could do any better. The New Horizons probe was the only one that got good high resolution images of it.

[summer pebble]

We did discover Eris which has more mass than Pluto long after Pluto was discovered (though technology did significantly improve by that time)

So yeah, I agree that the chances are greater than zero

[quick cairn]

Super good answers yall

[dark cargo]

It would be very likely IMO if you are defining the edge of the solar system to be within it's Hill sphere(how far the Sun's gravity sphere of influence reaches) which is ~178000–227000 AU aka VERY far away.

Meanwhile I found this source which ruled out Saturn analogs within 28000 AU and Jupiters within 82000 AU in the solar system: https://iopscience.iop.org/article/10.1088/0004-637X/781/1/4/meta
Which implies we won't be able to find pluto analogs to nearly the same distance.

Unless there is something preventing objects larger than pluto being out that far, the chances of such an object are nearly certain.

[thick heron]

Think about the objects with distant and highly elliptical orbits, like Sedna, that we know of and realize they were discovered when they happened to be relatively close to the Sun. There has to be many more we haven't discovered yet because they are at the distant part of their orbits now.

[woven kite]

regulus and moon occultation. i did not see this coming ahead of time so i did a quick shot with my zoom lens

[low oar]

Aye I got a pic too of it

[woven kite]

yooo thats awesome

[low oar]

thanks

[elder venture]

Very very high. The outskirts of the solar system could technically house a Uranus-sized planet in the right conditions that’d we would have trouble finding (literally Planet X), we would require to calculate its position using it’s gravitational impact rather than imaging

[hasty hull]

First image since like November

with the 6” dob

[winter moat]

great picture :D

[quick cairn]

Awesome answer

[ruby compass]

wait till bro finds out about the ort cloud

[ruby compass]

insane detail on io

[flint siren]

there's no detail on io..

[rain mauve]

average seeing

but theres an eclipse

[quick cairn]

Well ik that obv

But those objects aren’t nearly that size

[ruby compass]

how do you know?

[quick cairn]

….

[south nest]

It’s even says estimated, as far as I know we haven’t actually found any true Oort Cloud objects, excluding comets.

[main flume]

EEEEWWW GOOGLE AI

get ur mininerd revoked!!!!!

secons hands thinker :/

[graceful creek]

actually how big is that

how much % is it from our sun to nearest star

[flint siren]

The principle of the Oort cloud is to be a grouping of small size objects.

[flint siren]

Reprocess from the 12/30

[glossy frigate]

Dam

That's wonderful

[quick cairn]

What’s the moon above Io?

[flint siren]

Amalthea

[quick cairn]

Awesome detection

I assume that’s HDR?

[marsh elbow]

crazy

[flint siren]

Yeah ofc

that thing is mag 14

[quick cairn]

Yuh

Need to try that with my 10”, was that derotated?

What I mean is how much integration?

[quick cairn]

Lack of evidence does not suggest an alternative answer

[ruby compass]

Never notised amalithea

Mb

[flint siren]

Yeah derotated. About 36 mins.

[quick cairn]

Seeing looks eh

[flint siren]

huh ?

you mean on my capture ?

[quick cairn]

Yeah

[flint siren]

Yeah wasn't the best, but still enough to reach the limit

[rain mauve]

With 8 inch right?

[flint siren]

yeah

[rain mauve]

For me it looks good!

I mean I cannot capture amalthea lol since my aperture is way too low xD

[low oar]

toms gonna map that one next

[olive saddle]

I'd like to see what Astro Tom and Damian Peach could do with each others equipment, Tom on the C14 and Damian on the 24" newt

I wonder if there'd be a noticeable difference compared to their usual images, assuming their post-processing workflow stays the same

[elder venture]

Regular C14 or ehd

[olive saddle]

Whichever one Damian Peach uses, though I'd guess the EHD version since he probably uses it more for AstroPhotography than observing

[elder venture]

Yuuuuckkk

The C14 EHD is so horrible

[fading plume]

Damien would beat Tom because he would just ask grok to make an image of Jupiter.

[ruby compass]

Did Damien use his 14" for this?

Or does he have a 24"

[olive saddle]

Well idk which one he uses!

Oh god lol I just searched it up

of course he has TWO C14's

a normal one, and an Edge HD version

[ruby compass]

@flint siren

[flint siren]

You don't need me to figure that out

Pretty sure it's the 14" based on the resolution

[olive saddle]

Bro why do you keep tagging yoships and/or tom whenever you have a question

don't be that guy, not everyone exists to help you at a moments notice

there's a time and a place

[flint siren]

yeah and stop pinging me in pm bro, i get a notif either way

[woven kite]

jupiter and io

also i got a question for sct owners. how loose are the collimation screws supposed to be? some screws i did a full turn until i got a donut

[main flume]

they gotta be how the gotta be

[woven kite]

when all screws are in the "snug" position

uurrrggggg ...g.gg

[main flume]

btw, ur horribly collimated

[woven kite]

yar then i fixed it

it shifted a lot in a few days

[main flume]

[woven kite]

Nvm this i watched tutorial closely this time i got all of them snug in a perfect donut

[woven kite]

uranus first light

[rain mauve]

another jupiter

average seeing

[sterile marsh]

Jupiter and crater posidonius

[woven kite]

its in focus this time at least

i think the most i struggled with is the sun

hold on rgb align is way off

[woven kite]

different data from yesterday

[woven kite]

really suprised from the result of a 600mm zoom lens

live view

[winter moat]

Interesting program, I've never seen it before

Which telezoom do you use ?

[woven kite]

i think so too, it records at 5x live view which is close to a 1:1 pixel resolution

[woven kite]

sigma 150-600mm

[winter moat]

Ahh noice

I saw this on some random guys youtube channel

Have no idea what it even does lmao

oh its just like sharpcap for like dslrs i think

[quick cairn]

Let an Indian foreign exchange student use my equipment with my guidance yesterday to take these photos for a project, very happy about it for him.

[winter moat]

Wow really good :D

[stuck basin]

Why can’t I post pictures?

[woven kite]

how in the

[winter moat]

Yea I saw that too

Very impressive

and his only photo on his account

But I would guess that he has experience

[woven kite]

He probably got pics on another platform

I assume he fixed the telescope on a part of the sky and have it fly pass frame

[main flume]

magic

[ruby compass]

@flint siren do you think colimation or smt was off? doesnt feel very sharp even tho seeing was the best of my life

visible light live view

ir live view

[quick cairn]

Yeah man your poor seeing

[summer pebble]

how's this for a 6 inch telescope? anything better I could do?

[quick cairn]

Kennith for a 6” that’s probably the best you’re going to get (from my prospective. That’s absolutely insane.

That’s like the same as my 10”

@flint siren hey man, sorry to ping, just wanted your personal advice on imaging some of Jupiter’s smaller moons with my 10 inch. Do you use different exposure? Or is it literally just lots of integration with the rotation and HDR? Basically is there any secret to it?

[rain mauve]

full moon 2 february snow moon

50 panels mosaic untracked

[ruby compass]

Stars at the horizon werent flickering at the slightest

[ruby compass]

Not really tbh. Just shoot during times with moons

[flint siren]

If your data is good enough, it will show up if you nuke the stacks.

IR is usually better due to seeing, but there's not much more.

[flint siren]

Collimation seems fine. But your vis seeing is not really good tbh.

For IR, just lacks integration.

[graceful creek]

moon looks yummy

blueberry colored on some parts

orange brown is probably chocolate powder

[low oar]

💀

[rain mauve]

Feedback appreciated!

[winter moat]

Hmmm
The colors and so looking good

What happened here ?

The difference is very strong

[rain mauve]

This is my problem over there..., it's different seeing and I forgot to record that section

The one I record is 22.00 p. M

And one is 04.00 a. M

[winter moat]

Ahh

Ok then of course you can't do that much positive about it

[rain mauve]

I thought I was done recording and the 1/4 when I was blend it, it's gone lol

[quick cairn]

single stack kinda wild

[winter moat]

Nice thats sharp !

[quick cairn]

Thanks

[graceful creek]

blueberry clump in moon

[loud ledge]

Hey could you tell me what your fl was and what barlow did you use (2x, 4x etc)

[woven kite]

native 2000mm 8" sct

it wasnt stacked just a single 3 second exposure

[brazen moth]

Super sweet! I think that if you sharpen on luminance channel only, you will get less of that color-noise.

[quick cairn]

Haha maybe yeah, I use a color camera

[quick cairn]

Can you list processing, Christopher go is confused how you managed to get it because he said winjupos can’t derotate that moon

[loud ledge]

Btw would this scope be simular?

[woven kite]

pretty much i have the orange tube 8se one

[elder venture]

I hope youre not thinking of buying it

[flint siren]

You can align it like a normal star when obvious enough, using softwares like Siril. For example, that's Hyperion (similar mag to Amalthea), and when visible like that you can just align the frames using star alignment on the moon and then stack.

And that was with streetlights right next to the scope.

[loud ledge]

Hehe yes

[elder venture]

yes as in thats correct or yes as in youre thinking about buying it

[loud ledge]

Im thinking of buying it

[elder venture]

dont

Horrifically overpriced

if an 8'' SCT, get one used for a good price

meade 8'' SCT sell cheap these days

And even so if you want to buy new, get an RC8

The sharpness on an RC8 is superior

and its cheaper

[loud ledge]

Basically i just want a scope thats around 200mm, thats good for planetary astrophotography and my budget is (around) £1000

I say around because i dont mind if its slightly more or less

[elder venture]

There are far better options

[elder venture]

And what mount do you have?

[loud ledge]

Well its a bit complicated, although i am looking at a scope, im going to get a better mount first, rn i have almost saved up for the eq6 r pro

[elder venture]

That makes things easy.

[loud ledge]

Is it a good mount?

[elder venture]

Yes, though I wouldnt get it new since the payload per dollar isnt great

[elder venture]

~~https://www.astrobuysell.com/uk/propview.php?view=234009~~

10'' SCT for 750 quid

https://www.astrobuysell.com/uk/propview.php?view=232925

8'' SCT (deforked, the 10'' is not) for 310 quid + shipping is possible

[loud ledge]

I mean im close to getting the mount? Should i get it

[elder venture]

How much does it cost new for you?

[loud ledge]

1400 quid

[elder venture]

https://www.proxisky.com/products/Ragdoll20.html Might I suggest this beautiful harmonic?

its 1250 quid

[loud ledge]

I mean is it better?

I dont mind buying overpriced stuff lol

Aslong as its good

[elder venture]

Oh yeah

it has teh EQ6r payload WITHOUT a counterweight

with a counterweight its 30kg

[loud ledge]

Do you need to get a counterweight for this mount?

[elder venture]

Nope

its essentially EQ6 level without a counterweight

adding one just allows you to put heavier loads

If the biggest scope youll put on this is a 10'' SCT you wont need a counterweight

[loud ledge]

Its a bit more expensive for me

[elder venture]

It shouldnt be

its 1700 USD which is 1250 quid

[loud ledge]

Oh yeah true

[elder venture]

compared to the 1400 quid which is 2000 USD

[loud ledge]

Other than the counterweight being need for the eq6

Is it still pretty good?

[elder venture]

Its worth noting that since this is a harmonic youll need guiding for deep space photography

[elder venture]

Oh yeah

in total it weighs like 6kg

[loud ledge]

Cause im only looking to do planetary

[elder venture]

physical homing sensors

[loud ledge]

Fr?

[elder venture]

Yeah

Its super portable

Thats the beauty of a harmonic mount

[loud ledge]

Thats kinda good

[elder venture]

It also has RA brakes

[loud ledge]

But what about the mount part

Like

The bit that attaches below it

[elder venture]

The tripod or what exactly

[loud ledge]

Yeah tripod

[elder venture]

oh right i forgot about that

their official tripod is 250 USD

[loud ledge]

I mean

Is the eq6 r pro still good?

[elder venture]

weighs 2.1kg

[elder venture]

For sure but youre paying more than its worth

[elder venture]

https://www.proxisky.com/products/CF40.html

[loud ledge]

Im more familiar with the skywatcher mounts tbh

[elder venture]

It runs on onstep which is ascom compatible

pretty sure you can even just run it on your phone so its straight forward

[loud ledge]

The eq6?

[elder venture]

If I were you I'd get the Ragdoll 20. Way lighter, way more portable and it can hold a lot more

[elder venture]

the Ragdoll

[loud ledge]

Hmm

I might consider getting ut for portability

So the ragdoll + tripod + a used c10?

[elder venture]

Thats what I would recommend yes.

[loud ledge]

Btw i already have a camera for this

I have a Uranus M monochrome camera

[elder venture]

Spec sheet for the ragdoll *

[elder venture]

also id pick the option with a counterweight bar if you want to upgrade to something bigger

costs like 20 bucks more

actually no 14

[loud ledge]

Where should i buy the ragdoll btw?

[elder venture]

Directly from proxisky

They cover tax/VAT and shipping cost

[loud ledge]

Oh thats a real life saver

I hate tax and vat

[elder venture]

also just for reference

in theory

that mount could hold a C14 without a counterweight

though youll probably want one at that point lol

[elder venture]

also for what its worth thats a really good camera for what you want to do

[loud ledge]

Wait

[elder venture]

it sold already :/

no way they both sold that sucks

Well theres still this celestron C9.25
https://www.astrobuysell.com/uk/propview.php?view=234688

[loud ledge]

Can you add a go to to the ragdoll?

And do you have to add an onstep/motor?

[elder venture]

The ragdoll is a Goto tracking mount lol

[elder venture]

Nope

[loud ledge]

OH

Like so its all built in

[elder venture]

Yes

Onstep is the hardware they use

[loud ledge]

Yeah i guess im buying this

[elder venture]

OnStepX to be precise

[loud ledge]

Im only like 250 quid away

[elder venture]

It’s really good

And for further reference it’s on par if not better with ZWO‘s AM7

[loud ledge]

So the issue is just buying a celestron 10 inch used whenever i can?

[elder venture]

It’s buying a Meade or Celestron 10 - 12 inch whenever you can

Celestron only makes the C11 in that range

Meade only made 10 AND 12“ in that range

So buy whichever you stumble across used and can buy

[loud ledge]

Wait

Does it cover customs/imports?

[elder venture]

It shouuulllddd

[elder venture]

You can ask though, Proxisky has a discord server

[loud ledge]

Thats good

Wait do they sell out?

[elder venture]

Wdym sell out?

[loud ledge]

If so can they go back in stock

[elder venture]

Oh I see what you mean

They can sell out but it barely ever happens, especially now

[loud ledge]

Alright thats good

I gues ill get ragdoll 20 + CF40

And then a celestron 10-12 whenever i can

[elder venture]

Celestron or Meade

[loud ledge]

Yeah

[elder venture]

And yes that sounds good

[loud ledge]

Wait

For used ones

How do i know theyre still good

[elder venture]

Remember, with counterweight bar

[loud ledge]

I dont wanna get something that could be damaged or whatever

[loud ledge]

Yes

[elder venture]

No dents nor scratches
No water marks anywhere
Smooth focus
Somewhat clean optical surfaces

Dust isn’t an issue

Dirt or streaks is

[loud ledge]

Alright thanks

[quick cairn]

How long were you’re exposures?

[flint siren]

13.96ms usually

[quick cairn]

Thanks, I was trying to explain to him how you do it because he doesn’t understand, he thinks with that exposure time it’s not possible but isn’t it just SNR

He said you can’t use long integration because it moves so fast, guess hes trying to understand

[flint siren]

That moon is fainter and that was with 15ms IR850

[quick cairn]

He said it’s impossible, idk what to tell him

[flint siren]

It's not long integ. I use my 2 mins stacks, nuke them (which makes it appear), align onto amalthea and then stack.

[flint siren]

Duif, Tom have done it like that

From Duif, i'm sure that's a normaly exposed stack

[quick cairn]

What’s your F ratio when imaging this?

[flint siren]

Duif's F/22, mines F/26.

Tom's image, possible even right next to the planet.

From another user, i think that's with a 6".

[marsh elbow]

bro the c14 is 21 kg

[elder venture]

yep.

theoretically it could hold it

it would have trouble but it technically could

highly disadviseable

[marsh elbow]

Yeah but it wouldnt be good at all

I wish proxisky made a mount that can handle 50 kg

[elder venture]

would still handle it well with a counterweight

[marsh elbow]

Maybe

But its going over the 50 percent theoretical limit

[elder venture]

eehhh thatd be in the region of observatory grade mounts

[marsh elbow]

Like the eq8

[elder venture]

Harmonics are a bit different

[marsh elbow]

Ig

[elder venture]

and you have to consider we are talking planetary

[marsh elbow]

Oh yeah

[elder venture]

celestron sold a set with a CGE and C14 a while back

20kg payload on the CGE btw

[marsh elbow]

For deep sky its almost probably unusable

[elder venture]

mmm no

[marsh elbow]

But for planetary maybe ig

[marsh elbow]

Oh

[elder venture]

youd need a reducer and great guiding

but its definitely doable

the mount isnt the limiting factor at that point

[marsh elbow]

Also is a c14 even worth buying

[elder venture]

its the fact youre using a C14

[elder venture]

no

[marsh elbow]

Oh

[elder venture]

the only singular upside is that it doesnt weigh much for its aperture

for the price you coudl literally get a carbon fiber truss RC16

[marsh elbow]

Thats hella cool

Or put a 16" newtonian on it maybe

Wait

a 16" dob is way more cheaper

[elder venture]

We are talking cassegrains here

[marsh elbow]

But its probably not a good idea to put it on a ragdoll

[marsh elbow]

Ok

[elder venture]

a 16'' newtonian would weigh a ton more too

[elder venture]

nor is it a good idea to put an RC16 on it lol

it weighs more

[marsh elbow]

Oh yeah

How about a hubble optics 16 inch?

Ok idk

Prob not a good idea either

[elder venture]

9500 EUR used

this is a meade 16'' aspherical SCT

they brand it as an "advanced RCT" which it definitely isnt

Schmidt Corrected spherical primary with hyperbolic secondary

[marsh elbow]

Dang

[elder venture]

and consider thats the entire system, including tripod and fork mount

the C14 costs 10000 EUR as an OTA

[marsh elbow]

bruh

Also i chechked the weight on the optical tube of the hubble optics 16" dob

Its 24 kg

So the ragdoll could barely handle it

[elder venture]

would theoretically work for planetary but you have to consider its physical size

its a goddamn sail

[marsh elbow]

True lol

Its very long and large

[flint siren]

Jupiter prime

Raimbow colors

[low oar]

I used my C11 for something other than planetary for the first time, and this is the result

the core of orion

but i processed and shot it like a planet so 🤷‍♂️

[quick cairn]

Reminds me of Tom’s viral Instagram Jupiter

[flint siren]

It should, it's from the same moment

[quick cairn]

Hahaha

We were imaging at the exact same time

Here is my last orion :D

and here with lucky imaging

[quick cairn]

f/15 8” receptor Orion

For fun

[rain mauve]

How to shoot Orion core untracked?

[winter moat]

Best not with a Barlow

[rain mauve]

I mean what settings in the cam and how to capture the Orion core with planetary cam?
I use sharpcap tho... Is it using ser files?

[winter moat]

hmm Used Fits Files not ser
and maybe like 1s exposures

Like you have a new so i would guess 600mm fl

[rain mauve]

900mm lmao

[winter moat]

Oh

then you probably have to shot even shorter

[rain mauve]

Yeah I have no problem with this

[winter moat]

You can use the 500 rule

[rain mauve]

How to count it if the pixel size were 2.9 um?

[winter moat]

Idk

Just search online

"500 Rule Calculator" or something

[rain mauve]

Alright it was 0.2 second

[winter moat]

good

Then go with that

[main flume]

only a scope?

rc 8 is 900ish pound

[quick cairn]

OMGGG

[terse night]

Why 200mm?

With that budget I'd look for a fat dobsonian

And then you need a planetary camera

[brazen moth]

Hi there! Could you all help upvoting Eise.app on ProductHunt?!? https://www.producthunt.com/products/eise-app?launch=eise-app-photos-of-planets-moon-sun

[elder venture]

He has a Uranus M

[somber stratus]

Can't get much more than 200mm w/ GoTo for £1000.

maybe a great second hand deal will get you 300mm

[elder venture]

There’s also the romer optics ezgoto

Around 300 usd and compatible with the GSO bearing dobs

[terse night]

I didn't consider goto, I would prefer more aperture over goto

[somber stratus]

Hmm, not sure about that. Manual is far more limiting that you'd think.

[elder venture]

Also consider the fun factor

[somber stratus]

or lack thereof

[elder venture]

Yep. I’d honestly prefer a Goto 10 - 12 inch Cassegrain for imaging than a manual with more aperture

I suppose it’s a personal preference thing

[somber stratus]

Tracking is a necessity over 300mm aperture due to the focal lengths involved. Maybe not goto specifically, I meant to say tracking. Can be EQ plate.

[terse night]

I guess that it makes sense for imaging, I'm a fan of manual mostly because of observing, where finding the targets is part of the fun imo

[elder venture]

Oh yeah I meant tracking too

[somber stratus]

Oh yeah for visual observing, manual is more than adequate

[elder venture]

Finding is rewarding, recentering every few seconds not really

[terse night]

Tracking sure, I meant goto, one of the two is also way easier to DIY

Especially if you use a wedge

[somber stratus]

yeah

[elder venture]

Also true

Though SCT in particular are really small and light for their aperture

My 12“ truss dob OTA weighs more than a C14

[terse night]

But does it weigh more than the C14 AND the mount? I doubt that

[elder venture]

Well the dob also needs a mount and it’s not light

In my case it’s really heavy at 18kg

so yes technically it weighs more than a C14 + mount

Though you could knock off a few kg by building a new one

[terse night]

Just the mount? That's way heavier than I thought

[terse night]

I consider "dob" to mean mount and ota

[elder venture]

I said OTA though

[terse night]

My brain simply didn't register that part

[elder venture]

It is a big boy

Manageable though

Lugging around the 24kg tube is worse

[quick cairn]

Does an EQ plate allow tracking maybe not goto but tracking in itself? Or do I need more?

I’m considering buying a Hubble optics 16”. But the goto version which I don’t need goto just cloak drive style tracking “point to”, anyways the goto is 6k~ and the scope by itself without tracking is 2300~

[ruby compass]

a motor

[quick cairn]

Hey you got mininerd good stuff

[quick cairn]

can someone help me find downloadable jupiter hubble data?

i cant find any anywhere

[flint siren]

https://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html

Once you've clicked on search, you have data.

You can select the images (1) and once you're done and you have a selection you wanna download, click on (2). This thing will open up and click on (1). If you've download data in the past i recommend emptying this thing (2) unless you wanna download past selections, again.

[quick cairn]

Thanks brother

[flint siren]

If you need any help with derotating those (it isn't simple due to the dates not being with the files), i'm here.

[sharp ridge]

Watch my yt video

Anyways

[sharp ridge]

Id say eq plate

Hubble Optics goto isnt the greatest

[quick cairn]

Eq plate will be much cheaper too right

[sharp ridge]

Yes id assume

[quick cairn]

I really can’t image 3,000$

[sharp ridge]

you can diy one iirc

[quick cairn]

However I’ll need to be able to track well at 7000mm

[quick cairn]

Okay cool!

[quick cairn]

Ken, that data you posted a while ago of Jupiter is like Hubble level, seeing was unreal haha

[winter moat]

nanana 🎶🎶

[quick cairn]

😭

I have access to a 24 inch reflector anytime I want. The issue is it’s a solid tube so tube turbulence is really bad plus for some reason. The club is absolutely incapable of keeping its collimation good. Don’t know why it’s so difficult.

It’s mainly used for deep space observing and I’m the only person ever in the history of the club to figure out how to get a camera to focus on it

Since it’s used for observations, the collimation doesn’t have to be perfect and people don’t notice, but for planets it’s very obvious

But imaging with it is so hard

I can tell by the stack that it has very high potential resolution

But getting there is going to be such a pain with all the little flaws + I’m not allowed to collimate it myself

I could, probably better than the observatory administrator no disrespect but he’s very old

[ruby compass]

my out of colimation 8" images are shaper 💔

[flint siren]

No 💔

How can I remove a section of an AVI file in Autostackerrt4?

[brazen moth]

Ah wow! I forgot we're going to see more rings soon!

[flint siren]

Export the AVI file's frames, take out those that you don't want, reconvert to AVI and send in AS!4.

You can use PIPP to do that.

[brazen moth]

What's wrong with the data you want to have removed?

[cloud copper]

it's clipped

here is the stack if someone want's to give it a go

[brazen moth]

As in too many 100% bright pixels? Or clipped on the side of the screen?

[cloud copper]

as is side of the screen 🙂

here is what I got, I'm not the best at processing tbh

[brazen moth]

Better than what I cooked up 😄

[brazen moth]

ah yes, it's odd Autostakkert doesn't do that itself.

[cloud copper]

Lol

[brazen moth]

Could you throw your vid in https://eise.app and see if your clipped frames are properly ditched?

[main flume]

tfym?!?!?!?!

[quick cairn]

Huh?

[main flume]

wy cant collimate

[quick cairn]

It’s a 10 foot tall behemoth solid tube

The club owns it, you need giant screw drivers to swift the bolts

These things are massive

[main flume]

whats the appature?

oh

24"

mb

[main flume]

do some dso :3

[quick cairn]

Bro not possible

The tracking isn’t constant

It realizes it’s off and corrects

Correction tracking

Orion 3 second exposure with iPhone and 54mm eyepiece through it though

You can see many many tiny specs of core stars visually

[brazen moth]

Can't you get a "lesson" and an "approval" from someone to collimate?

[quick cairn]

No

It’s a rule not to mess with it

Only the administration can

[brazen moth]

But you get a diplima that says you won't mess with it.

[quick cairn]

I mean… it was 30 grand

Lmao

[brazen moth]

so you become the administration

[quick cairn]

Lmaooo

They collimate normally once a year

I got them to a few weeks ago and they didn’t even get close

[brazen moth]

Haha what. It's just a decision from someone that you cannot be the admin. That can just be another decision.

[quick cairn]

Jupiter over the next 12 hours will be interesting

[elder venture]

Ooo which one

[elder venture]

Yikes

[cloud copper]

Why am I pulling the same details as a 6” with my 12” dob?

[winter moat]

what 12" dob do you have and which camera do you use?

[cloud copper]

Omegon advanced X and Player One Ceres-C imx224, uv/ir cut, 2.5x barlow, no adc

[winter moat]

You need a 3.8x magnification

So in short you are undersampled

[cloud copper]

What barlow should I buy?

[winter moat]

you could use some spacers to give you more magnif on your current barlow

[cloud copper]

Tried it but it gets really dark, and I need to crank up the iso to the point that I can’t get any good data

[winter moat]

ok then buy somthing like this

ore a 4times

there is no 3,8x barlow

[candid flare]

why would you want an 8x barlow

[winter moat]

?

[teal sandal]

he meant a 3.8x barlow, not a 3x and 8x

[low oar]

The sent me the Uranus M for the eclipse

[elder venture]

[somber stratus]

https://tenor.com/view/spinning-diamond-gif-21691719

[somber stratus]

If imaging train is the same, it'll be seeing, acclimatisation or incorrect sampling. If it's not those, then your mirrors are to blame.

[cloud copper]

Tom, how do you collimate your scope?

I have a bit of trouble with getting mine spot right

[somber stratus]

462mc & all-sky lens inserted into the 2" focuser, then use sharpcap circular overlay to align the secondary. Visual inspection with a collimation cap to finish off.

[cloud copper]

Can I get accurate only with a collimation cap(1,25”)

[somber stratus]

Then fine adjustments based on how intra/extra focus looks on the live view, but you have to be highly experienced to know what to look for as you change focus, and which collimation screw to turn.

[somber stratus]

Assuming your secondary is accurate, yes, but this is unlikely to be perfect.

[cloud copper]

Is it possible to collimate the secondary only with the cap?

[somber stratus]

Often you need to adjust both mirrors if you haven't collimated in a while and/or the scope has been taken out of storage or bumped around

[somber stratus]

no

[cloud copper]

What do I need

[somber stratus]

how I do it^

any cam works

just need an allsky lens, I use the stock one that comes with the 462

[cloud copper]

I have a Ceres-c form player one, will it do?

[somber stratus]

Can't see why not.

You take your structure data in NIR, and your color in color and combine them

[low oar]

[quick cairn]

That’s not an explanation though

Can you break it down

[quick cairn]

Don’t you also need pretty good seeing to fine collimate like this with a live view?

found out linked wavelets give me a lot more detail (theyre both linked, different sliders)

[quick cairn]

I got the data, cloudy but had a few moments of good seeing.

Will post later

Going to use wavelet decomp

[silent mesa]

Same, I’m stacking rn

[quick cairn]

You probably got better data than me, what’s your aperture? I’m going to use wavelet decomposition.

[silent mesa]

8 inch

[quick cairn]

I have a 10” but clouds

You deff got me but let’s see

[silent mesa]

Same

How was your seeing?

[quick cairn]

Seeing when clouds cleared was probably 6-7/10

But clouds made data so inconsistent

AS4 can’t handle the change in brightness

I was dumbing it down for my gf

[silent mesa]

This is was I got from the night

[untold spear]

Jupiter from my new camera, Player One Uranus C

[marsh elbow]

Use astrosurface

It gives you the same results as AS4 but its just simple and just better in my opinion

[quick cairn]

I’ll try

I use astrosurface over registax but

[sand umbra]

Still great live view

[somber stratus]

no, you use "how" the image defocuses

if a double image appears preferrentially on one side of the planet for both intra/extra focus then collimation is off. It should be evenly spread on both sides of focus.

Hard to explain over words

[brazen moth]

Hey wow! Have you heard about https://uranumstack.com/ , and/or gave it a try? It's a "competitor" of Eise.app.

[main flume]

[main flume]

hope you see somethin cool

[hasty hull]

All I know is that it’s rarely stable that close to the sun

Even 610nm was pretty atrocious

[main flume]

yea

[cloud copper]

I need an opinion

What would work better on a 12” dobsonian and an imx224

A Zwo ADC + 4x focal extender

Or a Zwo ADV + 3x focal extender

Or the current 2.5x barlow

[quick cairn]

Focal extender is a Barlow?

[quick cairn]

The 3x

But it depends

What’s your 12” scopes F/ratio?

[cloud copper]

F/5

1500mm fl

[somber stratus]

Completely depends on the barlow's inherient focal length (of the optical element). This affects how much an ADC or spacer adds, magnification wise. An ADC + 4x isn't necessarily going to still be 4x effective.

ditto with the 3x

[cloud copper]

So the 3x

But should I go for a barlow or a focal extender

Or do they perform the same?

[somber stratus]

depends which barlow or focal extender. There are poor versions of both, and good versions of both

[cloud copper]

What do you recomand?

[somber stratus]

Also some of the time it's just a naming convention, but optically they're the same system

APM 2.7x coma-correcting barlow or TeleVue powermates are best. Explore scientific extenders are ok, and probably the only "extenders" I'd even consider.

[cloud copper]

I know you have used x-cell 3x, are they worth it?

[somber stratus]

They work well, and reasonably priced.

I didn't have an issue with mine when running it on the 16"

[cloud copper]

Is this the one you use?

[somber stratus]

yup, with ~130mm spacers

including ADC

makes it a 3.25x

[cloud copper]

Will I have the right sampling with it? My camera has big 3.75um pixels

[somber stratus]

Probably not. You need more of a multiplier than me. You could use a 2.7x double stack in the right spacing to get 6.25x. https://www.apm-telescopes.net/en/apm-comacorrecting-1-14-ed-double-barlow-625-x

You want to be aiming for ~f/20, at least.

if not closer to f/22+

[cloud copper]

Damn that’s expensive:)))

How do you calculate how much more the barlow multiplier will increase when using spacers/adc

Because if I use a 4.5x barlow , the f ratio will be 22.5, which is pretty good

[somber stratus]

M = 1 + (length of spacers in mm)/barlow FL

APM focal length is 62.9mm. It's not always easy to find though

[cloud copper]

Do you know the length of the Zwo adc?

[elder venture]

Wouldnt it then overcorrect the coma?

[somber stratus]

So for me, 1+130/62.9 = ~3x. It's actually closer to 1+142.5/62.9 = 3.25x due to camera sensor position adding 12.5mm

[somber stratus]

Nope, it's calculated to still work fine. Within planetary requirements anyway

[somber stratus]

40mm iirc?

can't remember

might be 35

[somber stratus]

This is also the setup you can do, for 5x effective.

Ethan uses something close to this.

[cloud copper]

Is the body length what I’m looking for?

[somber stratus]

Yeah

[cloud copper]

Are the Nomad 4x focal extenders by skywatcher any good?

For ir pass

I have svnony 685nm pass and zwo 850nm pass

Isn’t 712 the best?

[quick cairn]

Let me rephrase, for JUPITER

[main flume]

i like 1100nm tbh

[quick cairn]

So CH4?

[cloud copper]

For planetary you want to aim for a dedicated planetary camera, dslr isn’t good enough

[somber stratus]

Astronomik 642BP

[quick cairn]

Thanks

Ordered ✅

[untold spear]

Peter

[cloud copper]

Do you need mono camera to image IR data?

[candid flare]

Yes preferably

[elder venture]

no

well with a 685nm pass filter a monocam would be slightly better but

if youre using something like the astronomik proplanet 742 it makes nearly no difference iirc

[somber stratus]

Do you need mono? no. Is it recommended? yes.

[elder venture]

How huge is the difference of that though?

I havent actually seen a proper comparison side by side

[somber stratus]

OSC on left, Mono on right

both converted to mono for comparison purposes

[elder venture]

Woah

[somber stratus]

This is with RG610 longpass so probably the biggest difference you'll get.

[elder venture]

Thats definitely not negligible, i didn't know the difference was so huge

[somber stratus]

I mean it's hardily surprising. Only 1/4 of the pixels are contributing on the OSC sensor. You need about 4x the total integration to match the SNR.

[elder venture]

Well yes, but part of the NIR range goes through the bayer matrix entirely

[somber stratus]

Assuming RGGB bayer matrix and perfect transmission.

[somber stratus]

only above 850nm ish

which contributes little signal when running a 'short' wavelength long pass like the 610.

[elder venture]

Thats true

[somber stratus]

signal is dominated by the red

For CH4 imaging, OSC and Mono are practically identical

[cloud copper]

That’s insane

Thank you

[cloud copper]

Do you guys recomend using Weiner Deconvolution when processing planetary images, to be more specific, jupiter data

[quick cairn]

It’s not terrible, wavelets are better though

[quick cairn]

Tom, I have a Uranus c, IR pass filters, ADC, powermate Barlows, 250p skywatcher, in your personal opinion, is it worth getting a Uranus-m at this point as an upgrade? I am pretty dependent but also in college so the money I make working goes to the hobby, I guess it’s pretty up to preference but is there anything else in the price range of a Uranus-m more worth the money at his point in time?

Open to anyone’s advice

[flint siren]

Uranus with its 5 major moons from the 08/11. I tried a new processing technique on Uranus, using the Green and Blue from OSC to combine with Mono 610LP in an RGB composition, close to what ESA uses in their Hubble Uranus pics.

[quick cairn]

Awesome job yoships

Awesome snr

[flint siren]

Makes the polar cap a little bit red.

[flint siren]

I hope so, more than two hours of integration.

[low oar]

Similar to what I have, I have all that but no adc and a c11, and there’s nothing wrong with shooting color

I have both of the cameras

And you would need to invest in a filter wheel and filters if you wanna go down that route

At your stage I would continue to shoot color and maybe implement some IR for some detail boost and instead save up for a bigger scope

But that’s my opinion
