Planetary Imaging

[heavy mirage]

Jokes aside guys

Do you think it's a better idea to screw the filter on the camera, or on the adc or barlow?

[livid sierra]

I tried it on Venus once but for some reason it looked really bad when applying wavelets

[livid sierra]

Good question, I always screw it onto the camera nosepiece but I too wonder if ADC or barlow would be better

[heavy mirage]

Even with histogram at around 50% when shooting?

I know that crap on the filter becomes larger in the fov when put further away from the sensor

[livid sierra]

Yup

I always aim for 50-60%

[livid sierra]

It's an interesting question but actually I think it doesn't really matter. And like you said stuff on the filter becomes larger the further away from the sensor so maybe putting it as close to the sensor as possible is better, thus on the nosepiece

[cursive inlet]

@somber stratus what about 685 with uv ir cut 😈

Thats basically narrowband

[somber stratus]

A useless narrowband indeed

[somber stratus]

Wake up. New Jupiter dropped.

[ruby tartan]

I got clear skies 3 days ago but I was too lazy to get up

[somber stratus]

Outrageous

[steep apex]

Festoons

[ruby tartan]

I haven't noticed any difference yet, we'll have to wait for more images to see something, I hope to be able to register Jupiter in the next few days

[somber stratus]

SEB looks thicker to me.

[ruby tartan]

I looked at some files from last year and it seems to be a little thicker.

[somber stratus]

It thickened throughout the year, and appears to have continued. This also happened in 2010-2012 if I remember. Seasonal change

I think I asked DP about this during summer last year. Maybe it was the NEB, not sure.

Also this brighter part of the NTrZ looks so much thicker. Maybe that’s just IR though, will have to see.

[thick heron]

600mm club when?

[ruby tartan]

When I finish engineering college

[livid sierra]

Bruh I’m imaging

And I’m pretty sure someone in the neighbourhood is making a fire

I can smell it and it’s screwing up my seeing

[somber stratus]

Really getting to grips with a consistent & reliable colour process that doesn't look terrible. Only took 2 years.

And another. Completely different sky conditions so the output from the camera was quite different. Still maintains roughly the same colour palette without any manual tinkering.

[white prawn]

Am I the only one who is particular enough that I have to get the planet "righted" in my view?

[livid sierra]

Wym righted

[safe compass]

he means as keeping it in a right angle

for example, the big red thingy on bottom and the bands horizon

[livid sierra]

You mean North up

[safe compass]

Yeah, like that.

[somber stratus]

Depends what you like. South-up is technically convention but either works. I like to rotate to an arbitrary angle depending on the composition with the moons.

Just for aesthetics

[white prawn]

I typically position the cam so it's north-up; this is the first I hear of a convention, let alone that it's the complete opposite of how I would arrange it.

[livid sierra]

You can rotate the image in post so North is up

With WJ for example

At least imo it's easier to just have the camera in my scope so up on the HC is up on the liveview

Having the camera so North is always up makes it weird to control the scope

[somber stratus]

It's historical in nature, this image is technically right: #1019937457095065731 message

But yeah no idea why that came to be.

[white prawn]

I know it can be rotated in post, but is there a particular reason for convention to be South-up? Oh, scope control. Hm. Might try it south-up sometime. I didn't notice anything weird about control; then again, right now I manually control the scope so I just twist the knobs in the direction they need to go and not worry about how it should technically go as much as keeping the image in sight.

[somber stratus]

Doesn't really matter in the end. Do whatever you prefer

[somber stratus]

It's just as per monitoring of storms

[white prawn]

I prefer what makes things easiest. 😄

[somber stratus]

north-up would also do. It's easier to align images to the horizontal bands, so helps their study.

And of course WinJupos outputs as north/south-up, regarding images taken in more recent times.

[white prawn]

WinJupos?

[somber stratus]

Program that people use for derotation. It also has planetary ephemerides. http://jupos.org/gh/download.htm

[thick heron]

I would argue north-up has replaced south-up as convention for years now that visual has been replaced by imaging for serious observations.

Even when I started ten years ago i would say more images were north-up vs south-up.

And now the gap feels much bigger.

[somber stratus]

That’s fair. Yeah I just knew back in the day it was south-up. Either are accepted though as you say.

[ruby tartan]

I'll have to wait until the 300mm arrives to start the Jupiter season

😔

[candid flare]

will lower ISO reveal more detail and not make it look crap

pretty sure it needs more dynamic range?

or is it intergration

[near quiver]

nah you need more resolution

more focal length will do that, or smaller pixels

[livid sierra]

How high was your iso

[candid flare]

6400

[livid sierra]

Wtf

Why so high lol

The moon is bright af

Yeah I’m p sure you can get a better image

Was your exposure 1/4000?

Like the shortest possible exposure

The moon is really bright you can just do exposures of under a second

[candid flare]

more like 1/2000

6400 is what i use for deep sky 🤣

[heavy mirage]

I want

They make 24" scopes lol but for about 100k usd

[somber stratus]

Don’t we all

[thick heron]

If only there was an alternative with the same aperture…

[ruby tartan]

Home made mirrors

[ruby tartan]

April 8th Jupiter Map

[somber stratus]

March 1st for comparison

[ruby tartan]

My impression or the GRS decreased?

[somber stratus]

i've overlaid them in PS, and looks about the same. The widening of this white section is most notable i think

Oval BA has definitely shrunk though.

This barge has grown, now outsizes the GRS. Completely motionless too wrt the coordinate system.

[white prawn]

And @ruby tartan hello, what do you use to get the map like that? Right now when I image Jupiter I just take a 3min video and extract the frames for subs, then stack/process from there. That way I don't have to derotate. I'm sure that WinJupos is involved, but what else?

[somber stratus]

Oh lol those are Juno maps, constructed from the orbiter. NASA/JPL associated.

I wish we could match Juno...

but sadly not

[white prawn]

Just need a bigger scope

[ruby tartan]

I hope to be able to capture Jupiter by the end of the month, the sooner the 300mm arrives the sooner I capture

[safe compass]

I hope to be able to capture Jupiter by end of the year, more money i get, sooner the makutsov arrives.

[white prawn]

I'm waiting for it to come up in the evening, this fall. Tried to image it in Feb and ouch. Pastel looking quality. I've been told that an ADC could help.

In the meantime I'm reprocessing stuff that I took last Sept. 9/9/2022 was really good seeing.

I'm leaning to SCT and looking to 14" - 16". Trouble is one of those costs at least 1/4 the cost of my car and I can't afford that much.

[safe compass]

Same here, but the issue is my money income.

I am 15 years old and jobless.

[somber stratus]

Barge is visible in Clyde Foster's May 11th image too.

matched coords

[white prawn]

My job just can't afford my hobby.

[safe compass]

my pocket money can't either

[white prawn]

Here's a q. How do we know that Jupiter is spinning as fast as it is? How do we know it's not just cloud rotation and the planet isn't just practically at standstill?

[somber stratus]

At a guess, probably the oblateness. Wider at the equator than the poles. A ratio of the polar/equatorial radii could be used to obtain a rough rotation rate if the mass/density is known.

Whereas with Venus for example, the planet is a near perfect sphere as it rotates so slowly. The clouds however do circle the globe much faster.

[white prawn]

https://tenor.com/view/ohm-math-mathemagician-magician-simpsons-gif-21426408

[somber stratus]

Also, i guess you start hitting an issue with "how do you define Jupiter's surface, as there is no solid ground?"

What else other than clouds, can you use.

[white prawn]

I thought the core was solid at some point

[somber stratus]

Sure, but we can't see it.

I'm almost certain it's the oblateness that is used. I guess with sensitive enough instruments, you could measure the blue/red shift of the limbs, but this is very hard.

[white prawn]

Kind of amazing how we've measured stuff w/o seeing it. It would be pretty neat if we could get something that could go to the solid surface and send stuff back up. Even if it only lasted a couple of minutes, like the Venus explorer that the Soviets sent

[thick heron]

The inside being completely still and the clouds spinning around in just under ten hours would generate tons of heat from friction. Jupiter’s rotational speed at the equator is 60% faster than the ISS orbits Earth.

[white prawn]

Would that light the clouds on fire and set it as a star?

[safe compass]

to not mention the pressure.

[safe compass]

lol nope, not enough mass to fuse hydrogen into helium

[white prawn]

To be fair, I wasn't thinking of fusion as much as just generating enough to light the atmosphere up and that being enough heat to subsequently burn the planet.

[safe compass]

but yeah its good question what happened if a fire were to spark inside the atmosphere of jupiter

[white prawn]

Might take a lot. I know that the remains of a comet hit the planet a while back and there were a few new spots in the atmosphere for a few days but it didn't ignite.

[safe compass]

What kept the fire from spreading?

[white prawn]

Fire needs 3 things to start/continue. 1) oxygen; 2) combustible material; 3) spark. Any material can be combustible at high enough temps, for example, meteor/ites. However, without oxygen nothing burns unless it can produce its own oxygen (thermite for example) or burns in a way that doesn't involve oxygen (stars for example). Knowing that and not knowing the exact composition of Jupiter's atmosphere make for interesting exploratory q's.

[topaz elk]

im not sure but oxygen can be replaced with another compound right?

as long as its an oxidizing agent

[safe compass]

I forgot about the triangle lol

[white prawn]

Not sure, not an expert, but oxidizing by its name involves oxygen so there's that.

[topaz elk]

yeah oxygen is the most common oxidizing agent

but combustion can be replaced with other compounds tho

not sure how abundant they are

[jaunty flame]

I wonder how horrible a diy 3 mirror system would be

Horrible to build

But would theoretically give you decent results

For dso

Not really worth it for planetary

[candid flare]

Huh

[coarse aspen]

just restart discord its a bug

[white prawn]

Why not? Seems to me the images would be crystal clear

[heavy mirage]

Will try again in a few hours with a nice 88 degree pass!

Space station attempt, still having some issues with the slewing with the sat tracker app

Also it's out of focus by a bit lol

[steep apex]

Is this manual tracking?

[heavy mirage]

No, it's using the sat tracker app with goto. But I was having some issues with the slewing so I had to push it around a bit to get the iss in view

[steep apex]

I see that, great work

[heavy mirage]

Thanks, but tbh this was a fail lol

here is my best one yet, from last year

[steep apex]

I wished I payed attention to captions more…anyways good luck on your attempt in a few hours!

[heavy mirage]

Haha no worries, thank you. I'll post soon!

[soft skiff]

WOAH

damn takes lot of skill to do that

even with the goto

[heavy mirage]

Thank you 🙂 @soft skiff

[soft skiff]

Damn i am a long way to be able to do that once my dob comes

[heavy mirage]

Just keep trying, you'll get a good shot of it one of those times!

[soft skiff]

yeah thanks!

[jaunty flame]

Main benefits you get are a faster speed and a larger image circle

But at the cost of an increased central obstruction

So it wouldn’t work out that different if not possibly worse than a newt

As newts central sharpness is actually quite good

[white prawn]

Ah, I see. Increased central obstruction would be a challenge then. "Looks good on paper, practical application can be less than desirable."

[jaunty flame]

Yeah

daylight jupiter? insane

[somber stratus]

Nah, that's at 12 degrees

Night time for him in the Philippines.

[coarse aspen]

oh didnt think jupiter was up in the night

[somber stratus]

Twilight, so not night per se.

[coarse aspen]

alright now it makes sense

About like that

[soft skiff]

you from philippines?

[somber stratus]

No, this isn't my image.

Christopher Go's

I'm based in the UK, 51°N

[soft skiff]

oooohh

i see

i was curious cause im from the same country

[ruby tartan]

@somber stratus, you already had a 12", correct? Could you send your best pictures to see what I can expect from this telescope?

[somber stratus]

Sure but they were taken in 2021 at an incredible 25° altitude. I will find them

one sec

[ruby tartan]

Ok

[somber stratus]

Jup (23°)

[coarse aspen]

thats insane

[somber stratus]

Saturn (18°)

both OSC with ASI462mc

[coarse aspen]

jupiter looked cooler in 2021

[somber stratus]

No IR luminance

You can definitely get better than this.

[ruby tartan]

Nice, I hope to get good results this year

[somber stratus]

I hope so too. I think your seeing will support it.

Encke division should be common to be honest.

Maybe not actually with the current tilt of the rings.

[ruby tartan]

And by altitude too, Saturn will pass zenith this year

New image of Jupiter from a friend here in Brazil

[somber stratus]

Nice

definitely highest res one so far

462MC + IR685 is kinda inefficient but does the job

[hasty hull]

Lookin good

[lunar hamlet]

I swear you are going to take one of the most detailed images of Jupiter shot from earth one day, your just so good at it

[ruby tartan]

As long as Damian Peach is alive, no one can

[lunar hamlet]

He’s getting damn close

I bet that if he had a huge scope, as big as the one Damian Peach used to get the shot (if he doesn’t already) he could get it

[somber stratus]

real

[lunar hamlet]

Jupiter

[coarse aspen]

The solution is to get a bigger scope than Damian Peach

[lunar hamlet]

And on a big mountain for less atmosphere and good seeing

Just chuck it on Mount Everest and hope for the best lol

[ruby tartan]

[cursive inlet]

Not only is he the best planetary astrophotographer, he is probably the drippiest one too

[coarse aspen]

i have never seen such drip in my life

yeah no, tom stands no chance

tom can be second best on earth

[lunar hamlet]

Still second thooo

Better then me

[somber stratus]

He's getting a SW 16" like mine afaik. He was asking me about it a couple months back.

Not sure if he has committed yet.

[ruby tartan]

😳

[somber stratus]

@ruby tartan Raw Jup data with the 12". Shot above was just a single stack so you should get something better if you derotate.

And sample of seeing. Was a good night.

[livid sierra]

Damn, that’s an awesome suit

Had a first attempt at ISS imaging tonight, sattracker worked really smoothly, just forgot to check if my powertank was in a good position for the real pass and it wasn’t so the cable got tied around the base at some point so the dob couldn’t slew further lol

Quickly switched to handtracking but I lost it for a good 10-15 seconds, right around when the iss reached peak altitude

So these are only the frames taken during auto tracking

[uncut glade]

Those are gorgeous! I can’t see any disturbances from the seeing as well, great acquisition!

When it’s about 2/3 of the way through the video, the individual panels create some kind of visual perturbance, with stacking I bet you could resolve panels as blobs!

[lunar hamlet]

Nah, that’s just cheating

Jkjk, that’s actually sick

[livid sierra]

Haha thanks, these frames are already stacked though

Might have another chance tonight and if I do I’m gonna try it with a 2x barlow for 3000mm fl

Should be a lot better already, given I’m using the right exposure

[uncut glade]

That makes a lot more sense LOL

I was so curious how your seeing was that good haha, well at 3000mm you should be able to see some more on the panels ;)

[onyx garnet]

can I get saturn's fainter inner rings with my c6

and maybe the encke div?

[stark abyss]

Hmmmmm

[lunar hamlet]

This is planetary imaging?

[stark abyss]

Lol

Kinda

[livid sierra]

How

[onyx garnet]

pls let me know, I gtg sleep

[livid sierra]

This was my Saturn back when I had my 6”

Might give you an idea

Taken in good seeing

You could also just image it and see what you get

Aim for 50-70% histogram

Adjust your exposure so that seeing effects aren’t extreme and adjust gain until you get 50-70% histo

Put your preview fps to like 10fps to see seeing effects

[somber stratus]

not encke

need ~11" or larger

[ruby tartan]

8" is enough

[somber stratus]

Hints of it, hard to differentiate between ringing and encke div

This doesn't exist in reality, its from the Cassini div and effects of sharpening/decon

Encke could be a similar ordeal with the background black.

But i do agree, probably have detected it here. Just making a point.

[ruby tartan]

I was always skeptical about being able to capture encke with an 8", but a friend insisted it was possible

[ruby tartan]

But I think I may have captured Encke in this image, as I was very close to the opposition

[somber stratus]

I agree given you use a newt

However, if it was an 8" SCT, then no. These have terrible ringing

[ruby tartan]

It was an 8" newtonian

[somber stratus]

Yeah i know,

I was saying, in theory if someone used a SCT then X to doubt.

Should be able to get it nicely with the 12". Look forward to the results

[livid sierra]

I'm so glad I didn't buy that 11" sct from that old fart from the telescope shop when I was trying to order my dob

I mean there was no chance I was gonna do that anyway, but still

[onyx garnet]

damn that's sad

But the fainter inner rings?

[somber stratus]

C-ring? pretty easy, you just have to overexpose a stacked image

[onyx garnet]

but the whole picture would be ruined no?

[somber stratus]

You can just adjust the curves instead

Idk, I usually don’t try to extract it

But it’s very easy to “detect” per se

Especially around opposition

[onyx garnet]

oh

maybe I can pop the 685 with uranus c

[onyx garnet]

what curves are you referring to?

[somber stratus]

Curves in editing where you can adjust dynamic range & contrast etc

[onyx garnet]

Oh

[heavy mirage]

My best Mars data from 2022 opposition, have a go: https://discord.com/channels/794642864218439681/1108541828707385344

[ruby tartan]

@somber stratus, have you tried capturing Ceres yet?

[steep apex]

What are those really dark spots?

[ruby tartan]

This?

[steep apex]

On the 5/14-17 one under the northern bands

[ruby tartan]

This?

[steep apex]

Yeah

[ruby tartan]

Thinking about it now, I don't know how to explain what it is, I think @somber stratus can explain it

[steep apex]

I think it’s a barge

I though the ovals were barges

[steep apex]

Maybe an eclipse of a moon?

[somber stratus]

Those are festoons. Appear blue in colour

I think they are upwellings of material from below but I honestly don’t know what causes them. Might research it now

[hasty hull]

Saturn this morn

[livid sierra]

Another iss attempt last night, handtracked this time because mount wifi was acting up

f/9.8 3000mm

[uncut glade]

Oh lets go I was right haha, details on panels! Awesome shot

[livid sierra]

I was also a little overexposed last attempt which didn’t help

And I could’ve had a much better result had my scope’s wifi worked properly

Might have another chance tonight and might try it with the 3x barlow then and try to get the wifi to work properly

[steep apex]

Very nice attempt! I’m wondering what they were doing to the outer panels

[livid sierra]

Wym?

The flare in the middle?

That’s a reflection

[steep apex]

They rotated it, you can only see the iRosa Solar Panels

[somber stratus]

This is completely normal as per the position of the Sun at the moment, relative to the ISS orbit. It's the most efficient orientation of the panels as to reduce self-shadowing.

If they all pointed flush with the Sun, these left panels would cast shadows on the other two, lowering efficiency

Happens in July too

[somber stratus]

This barge is massive!! @ruby tartan

[ruby tartan]

Danm

[somber stratus]

Measures 21,000km

via WJ

1.6x Earth diameter

It's been growing for the last few months actually.

[ruby tartan]

My 12" needs to arrive as soon as possible

No carrier wants to transport the 12", because of the size, I will have to pay 20% of the value of the telescope just for a carrier to bring it to my house

[somber stratus]

I lie, it's actually visible all the way back in June 2022. Just very small.

[white prawn]

Barge?

[somber stratus]

Yeah, massive.

Cyclonic (low pressure) colourless features in the NEB that appear stationary, if you're asking what they are.

[white prawn]

Okay, I'm going to have to look through photos that I've taken if it's been visible since June 2022 I might ahve something

[somber stratus]

Visible here in August. Near-central. Measures 15,000km.

[somber stratus]

I'm surprised i havent noticed it until now. I guess the red-coloured NEB material moving around the northern edge of it makes it super obvious here

[white prawn]

It's showing up in one of my eyepiece projection shots. Dang.

[somber stratus]

Not sure if that's the same barge, depends what date.

[white prawn]

Geebas don't show me that, makes me feel incompetent.

[white prawn]

Dec 10 2022

[somber stratus]

Let me look at the alpo maps to check. 1 second.

[white prawn]

Here's another, same night. Same mess, diff % of subs stacked

[somber stratus]

You're seeing the one denoted by the red arrow. We're interested in the blue.

This is a map from the ~10th

Just checked in Stellarium regarding the moon shadow position. You're definitely seeing the red.

Do you have another image?

[white prawn]

I'd say "how can you tell, the GRS can't be an indicator in either case, but I see how just looking at that. I may have to review, potentially process more.

[somber stratus]

Yeah, can just about tell based off the appearance.

moon position & time confirms it

[white prawn]

MAYBE these two? Likely not though. But it doesn't have GRS and I was focused on "Oh cool I got three moons!" Let me know if they're candidates for "should reprocess soon"

[somber stratus]

Date?

[white prawn]

9/29

[somber stratus]

nevermind, file name has it.

yup

Nope, it's the exact same face as last time 😆

[white prawn]

Yeah, that's when I started trying to get organized a little bit

DANGIT.

[somber stratus]

It's fine, looks to stay around for a long time hereafter. Should be able to image it in June/July coming up.

[white prawn]

That and I'm sure I have some somewhere that might not have been processed. There were nights that I just imaged for a bit and never got around to processing.

You know what's really sad though is that I bet I have one that does have the barge b/c it's between two gobs of blue but the processing was so junk that it just doesn't show detail.

[somber stratus]

The blue festoons are incredibly fast moving in the atmosphere. These are transient, it won't correspond to the same region.

[limpid topaz]

Hi guys, would a uranus c + 3x barlow be suitable for my 8" dob for planetary?

[somber stratus]

yes

assuming f/5 ish

[thin aspen]

Hi I’m a beginner and wondering if this shot of Venus is ok and where I should improve. Shot from heritage 130p

[nocturne zinc]

These shots are amazing, I am so jealous of your visuals😅 here's the best one I have and is from a 9.25 with Uranus-C... not even close to you guys🤣

[livid sierra]

@heavy mirage I might have to start attaching my uvir cut filter to my adc or barlow. When I stack the w47 and po uvir cut filter my camera doesn’t slide down the adc as far as it does with just one filter, which would cause the focal length to be a tiny bit longer than my ir images on Venus

I’m not sure if it has any noticeable effect on my bicolour images

But it was something I noticed a few days ago

When putting my camera in the adc

[livid sierra]

Yeah, I'm gonna put the po uvir cut on the adc next time and just the w47 on the cam

[cursive inlet]

What barlow do you use?

[hasty hull]

nice shot, when did you get this

[livid sierra]

Celestron X-Cel 3x

But I’m gonna put the uvir cut on the ADC otherwise I’d have to take my entire imaging train out to switch from 610nm to uv

[stark abyss]

I don't remember exactly but maybe last year

[livid sierra]

Or maybe the w47+uvir cut on the ADC together, but need to check if that fits

[somber stratus]

Late 2021.

i think

[hasty hull]

Imo it looks like it’s been flipped horizontally

This looks more like it to me

[somber stratus]

yup, late 2021.

I noticed this too

terminator on the left, and (fading) orange EZ

Means post-opposition 2021, so Autumn 2021. Does this sound about right, I'd be surprised if you thought it was last year? 😆 @stark abyss

[cursive inlet]

Yeah its probably a good idea, asked what barlow because for telecentric barlows like the explore scientific or powermates, the distance from the barlow to the sensor doesnt change the barlow magnification.

[livid sierra]

Got confused because you said “does” but yeah, that’s the issue the extra distance to the sensor causing a slightly bigger magnification

[somber stratus]

It's best to place all filters at the front of the barlow as per internal reflections, although it doesn't make much difference.

[cursive inlet]

Yeah my bad, edited it

[livid sierra]

Yeah np

[livid sierra]

Do you do that? That would be such a pain tho seeing as the barlow is the first thing in the imaging train

Having to take the whole thing out everytime you change filter

[cursive inlet]

Tom has real uv so he doesnt have the problem of the camera sticking further out I think

[somber stratus]

i don't use a stack yeah. Also my P1 cams came with a shorter 1.25" barrel so when i use RG610+UV/IR it fits inside the ADC anyway. My Omegon ADC has a little more space too.

But slapping on the front barlow still works fine.

I'd just leave the UV/IR on the front of the barlow. Then just change camera filter from W#47 to RG610.

I.e Violet+UV/IR for UV, and RG610+UV/IR for IR

Then you dont have to take out whole thing.

[livid sierra]

But 610+uvir cut makes shit for me

Lol

I’ll just do the adc thing

If it fixes the magnification problem then I’m good

[heavy mirage]

@livid sierra yeah, that's one of the issues I have too, so I might have to do what you're saying, ofc it also may be possible to get a shorter nose peice for the camera but idk if they exist lol

Oh wait tom just said his came with shorter nose pieces

[livid sierra]

@somber stratus why did your cams come with shorter nosepieces?

[somber stratus]

idk, it's just slightly shorter than the ZWO ones

by 1/4 of an inch maybe

not alot

[white prawn]

@somber stratus is that barge visible if the GRS is at the extreme right edge of Jupiter? Maybe I meant to say left.

[cloud copper]

Does anyone here have a 10" telescope?

[somber stratus]

That’s some bad seeing right there

[livid sierra]

I wanna try Jupiter but it’s still got such a small elongation

Thinking about it now though, I could extend the arms of our drying rack, hang a big blanket over it and use it for shade

[hasty hull]

j3rry does

[ruby tartan]

@somber stratus, New Clyde image

[somber stratus]

yeah saw this one this morning

on HSTJup

[cloud copper]

Finally some nice weather

[atomic briar]

You have a missed call

Just saying

[cloud copper]

Lol

[heavy mirage]

Is this at some event?

I like 😍

Lol

[cursive inlet]

I'm planning a heist, who's with me?

[heavy mirage]

As long as we both get one

[atomic briar]

Yes, in germany

[nova delta]

Risky, but i'll try to wake up tomorrow very early to shoot an hour before school 😬

[steep apex]

Is this a solar day?

102mm refractor
10mm eyepiece
Camera: iPod

[polar sequoia]

nope, thats a solar... rotation... a solar day is when the earth rotates an additional bit (4 minutes) so that instead of doing 360° it does that little extra to point towards the sun because it has shifted from a position where it currently isn't, further along this orbit.

cool thing is the year is not exactly 365 days, its 365.24~ causing a leap year every 4 years, but guess what, THERE'S MORE! even accounting for leap years there's still a small deviation (3 days every 400 years) so in 1584 pope gregory decided "hey we gotta fix this" so every century year thats not divisible by 400 we dont do a leap year

but you cant fix something that is completely broken, so to realign the calendar they just fast forwarded a couple days and from the 5th to the 14th of october 1584 nothing happened because that time literally did not happen, they went from 5th oct. 1584 with the julian calendar to the 14th oct. 1584 with the gregorian calendar

basically 10 days just missing from history

many people make a joke where they tell you to look up how many people were born from 5th to 14th oct. 1584 (0 people)

[somber stratus]

to scale

[polar sequoia]

lmao

i mightve gone down the rabbit hole a bit here

[cloud copper]

hello

does anyone here have an old philips toucam pro II (pcvc840k), because I am having some problems connecting it to sharpcap and I dont know where to start.

[wispy pagoda]

There's a similar story with newton's birth date no?

[polar sequoia]

England, like always, decided to be goofy lil kid in the europe playground and didn't change their calendar from julian to gregorian for a couple hundred years, meaning Newton was registered born 25th of december but 4th of january for the rest of the world...
silly england as always

[steep apex]

Now it’s one full solar rotation…
Thanks to Kerbal Madness and ANAKLO for the info

Same equipment as last time

[ruby tartan]

New Clyde images

[fading plume]

@ruby tartan @somber stratus
new jup image from me. Slept in so no nighttime lol. 36 degrees alt.

[coarse aspen]

wow great

sun was up

[ruby tartan]

Nice

Send to ALPO

[livid sierra]

I’m at a remote spot at 5am rn to image Saturn

Lol

[fading plume]

Grindset

[sharp ridge]

Shitturn at 15
Meanwhile it's past 40 here and I can't find time to image it

Negative grindset

[fading plume]

66 here. Only imaged once

I leave for work early

[livid sierra]

Yup 15°

Gotta get what I can get

Only reaches to 27° max here so

[flint veldt]

what is that program to do that

[somber stratus]

WinJupos

[somber stratus]

hell yeah brother

I'm not alone for once

@ruby tartan Am i tripping or does it look like there's a grey-ish streak in the SEB?

something like this

[ruby tartan]

Like this?

[somber stratus]

Yeah, kinda

The discolouring

Especially at far right.

I think this is actually post-GRS turbulence. GRS is just behind the right limb.

[ruby tartan]

🥹

[near quiver]

dont be sad because we're losing it, be happy because we got to see it and the losers in 2050 wont

[coarse aspen]

itll go back up... right?

right? 😢

[near quiver]

probably not, its been shrinking for decades

[coarse aspen]

its gotta spring back up

[near quiver]

if you look at pictures from the 90s or early 2000s its massive

[coarse aspen]

1991 Jupiter

[wary siren]

the GRS

[thick heron]

1890s from Lick Observatory.

[steep apex]

That thing was a giant back then!

[near quiver]

the fact that some dude in the 1890s took a better jupiter picture than me makes me want to cry

[somber stratus]

Long boi

[somber stratus]

This graph is misleading with a y-axis minimum of 10

[near quiver]

yeah but thats still about a degree shrinkage per year, at that rate it will be gone by 2035

[somber stratus]

Yeah for sure

Although I doubt it will stay at the same rate. Not sure if it’ll accelerate.

Conversely, it could be more stable when it’s smaller, and survive much longer. Literally have no idea. We’ll see

[near quiver]

i could see it going either way, but im with you on it not staying the same

[somber stratus]

Agree. I’m 50/50 as to whether it will speed up or slow down

[near quiver]

either that or it could get less and less stable as it shrinks and collapse at an exponential speed and collapse much sooner

[somber stratus]

Yup

[near quiver]

most of the results im seeing are using the same "20 years" number

[thick heron]

What about the 1870s?

Crazy how much JPEG compression there was in the 19th century.

[near quiver]

Ok I’ve got the 1870s beat

[steep apex]

Wonder what the bands were like back then

[thick heron]

I don’t think they were any different structurally, but probably change in color like they do now.

http://www.catchersofthelight.com/catchers/post/2012/07/20/Solar-System-Astrophotography-History-of-Astrophotography

1879 must’ve been a oddball season with the bands. Would’ve loved to see a high-resolution image.

I also think that was also the first year the Great Red Spot was observed to be red.

[steep apex]

They still have better images than me

[thick heron]

Speaking of events I wish there were high resolution images of: this dark spot on Jupiter sketched by Giovanni Cassini in December 1690.

https://articles.adsabs.harvard.edu/pdf/1997PASJ...49L...1T

[steep apex]

Even their sketches are better than my images

[coarse aspen]

its actually insane such good photographs existed so long ago

[hasty hull]

Yeah amazing

[heavy mirage]

Poopiter this morning at 11 degrees alt. Quick process of a single 2 min video. Still gotta get through a few more videos for final image

[hasty hull]

Looks awesome

Mars at 4.72”

[heavy mirage]

Very nice, I shot it too last night (Mars)

[cloud copper]

can someone help me get a better image from this saturn data, I managed to get this picture but I think you guys can do better than I did. Here is my final image:

and here is the data

I took the video today at 4am, with my 6" newton and my phones camera. I stacked 15% from 7000 frames and I used normalise stack 75%

here is the .avi file too

[somber stratus]

STrZ looks much more pronounced this year. Love to see it.

(White band south of GRS latitude)

[heavy mirage]

Looks like grs is moving down into it

Seems a bit lower than last year

[somber stratus]

More likely the SEB shifting around the GRS, rather than the GRS itself

I.e SEB has drifted north.

[heavy mirage]

I see, that makes sense

[quaint harbor]

how would the explorer 150p (not pds) on an eq 32 do for planetary imaging?

[cloud copper]

fine I guess

[quaint harbor]

@cloud copper I know the eq32 isn't very good but...
getting that and the scope for £100 hopefully

[near quiver]

it would be fine

[cursive inlet]

Gettin some plato rn

[cloud copper]

Is this a decent planetary setup?

And my curent telescope seben 150/1400

I am planing to use the camera as a planetary cam not as a guide cam

[livid sierra]

Spent hours trying to find Jupiter today lol

Did not find it and gave up eventually

[safe compass]

Did you use stellarium?

[livid sierra]

Of course lol

It’s daytime

I was sitting like this:

[cursive inlet]

Lol

[nova delta]

Laser finders really hate me, lol
Every time I bring my scope out it is very far away from where the scope is pointing

[near quiver]

@somber stratus how do you focus on the ISS? do you focus while its tracking? i tried last night thinking infinity focus would be relatively close but it was quite far off

i would actually be happy to get an answer from anybody, tom was just the first person that came to mind lol

side note, god damn tracking the iss is hard

i mean my tiny sensor isnt doing me any favors but i probably got about 10 frames

[somber stratus]

Star or planet is sufficient

[near quiver]

really? i focused on venus and it looks way off

but to be fair ive only seen the live view, it might just be blown out and i mistook it for being out of focus

ok actually focus isnt that bad

nevermind im an idiot

[somber stratus]

Common to overexpose it first time

It’s stupid bright

[near quiver]

i set the exposure pretty short, i made venus dim

but i think it might still be a tiny bit too bright

[hasty hull]

Exposure should be well under .5ms

To not get the motion blur

[near quiver]

let me finish running it through pipp then i can see if its any good

i think i actually got about 200 frames with it in, which is way better than i thought

ok its definitely overexposed

i thought the solar panels would be way brighter, theyre actually the darkest part

its not too terribly overexposed though

[hasty hull]

yeah panels are really dim especially in visible light

[near quiver]

ok, well, from my incredibly crappy first attempt, can anybody help me identify some features

im struggling to figure out what orientation its in lol

[cursive inlet]

northern limb

[steep apex]

For now, venus would be the best to focus on, but I think Jupiter would be the best

You’re saying that when you focused on Venus, the ISS wasn’t focused?

[near quiver]

nah it looked out of focus but it actually wasnt too bad

[somber stratus]

Single stack of UV tonight through a 2m gap in the clouds. Practice for tomorrow ig

[clear pier]

hey anyone with a uranus c have any gain and exposure recommendations for saturn?

[somber stratus]

Exposure 10-30msec, gain <300. Whatever gain is required to reach decent brightness, but try not to exceed 300. Depends on the setup.

I capture multiple 90-120s videos. Stack these in AS!3 as normal then with the stacked images I derotate them,

(to whoever deleted a message just now asking about Jupiter imaging)

[steep apex]

Sorry was just gonna re-write the question, thanks!

[somber stratus]

But try not exceed ~14mins total capture time (7x2m) as derotation starts to get artefacts

Also, I sharpen my stacks before derotation. Usually use minimal denoise and “oversharpen” them. Derotation will denoise them though averaging (stacking the stacks per se).

[steep apex]

So is de-rotating better than lucky imaging for planets?

[somber stratus]

It’s still lucky imaging… the individual 90-120s video captures are lucky imaged - with the best ~25% stacked in AS!3.

Derotation combines multiple of these individual images to further decrease noise.

[steep apex]

Alright, thanks for your time and the info!

[somber stratus]

Derotation is essentially an additional processing step, rather than an alternative one

If that makes sense. Np

[heavy mirage]

I tried focusing on a star or something before and whenever the pass happens it turns out to be out of focus. For my best pass ever, I focused on the ISS during the pass but that was when sattracker actually worked

[somber stratus]

interesting

if that is the case all of mine should have been better

as i've only ever used stars

[heavy mirage]

Haha, maybe you're right then. It's always so stressful when the ISS passes, I probably rushed focusing lol

But, if your tracking is gonna be good next ISS pass. Try focusing on the ISS

Just to make sure

[clear pier]

got it thank you!!

[ruby tartan]

.......

[heavy mirage]

sheesh

showing off my dream scope

[near quiver]

he went through all the effort to get that image but he couldnt figure out what it was called

[safe compass]

Still so amazing feat.

[near quiver]

yeah definitely

a lot better than mine lol

[steep apex]

The modules are so pronounced, wonder what he could do the the ISS

[livid sierra]

https://instagram.com/your.daily.astro?igshid=MzRlODBiNWFlZA==

Sheeesh

[cloud copper]

Guys do I need multiple videos of saturn and than derotate them or do I take one long one.

Keep in mind that Im using my phones camera

[coarse aspen]

Venus nightside just now

[heavy mirage]

Is this at peak altitude?

Or towards sunset?

[somber stratus]

25deg or so

[heavy mirage]

Neat

[somber stratus]

can't get over this UV data

supreme seeing

9/10 for sure.

[ruby tartan]

My 12" is supposed to arrive tomorrow, I hope it arrives

[thick heron]

Tom stole it.

Practice run for stealing mine.

[heavy mirage]

Gottem

[somber stratus]

[heavy mirage]

@somber stratus @livid sierra I know this I'd gear based, but what exposure would you recommend for Venus in UV?

I sometimes go up to 10ms in UV but no idea if that's a good

[somber stratus]

Depends how bright it is. Ideally 10-15ms as normal for Jupiter.

Anything under 20ms works

[livid sierra]

Mine are usually somewhere between that too

[heavy mirage]

Great, thanks. What about IR? Same same with lower gain? Or do you go for more frames?

[livid sierra]

I do +/-10ms exposures

8-10, 50-60% histo

Get a lot of frames

[heavy mirage]

Will do! I'll try it out maybe tonight

[livid sierra]

Good luck!

[heavy mirage]

Thanks!!

[somber stratus]

My IR today was 0.8ms

Bright.

[thick heron]

I was surprised 0.6ms at gain 0 was needed to properly expose Venus with my QHY5III200M a couple nights ago. My ASI290MM was used at 8ms and gain 10-30.

[somber stratus]

200M has tiny full well, that’s why

[heavy mirage]

Windy af atm

[cursive inlet]

😩😏

[steep apex]

When is the next triple eclipse on Jupiter?

[somber stratus]

Aug 2032 iirc

[thick heron]

Fake news. Three transits but only two eclipses.

2032 is correct at least.

[thick heron]

Next one is in March 2032.

Make sure it's up where you are or else it doesn't matter. I get it in daylight.

[somber stratus]

ah yeah, March. Idk where i got aug from

Oh, that triple transit was August.

[somber stratus]

Gotta get them to line up. Only proper way of doing it.

OCD compels that the shadows form a line

[steep apex]

Thanks for the info

I miss it by a slim bit 🙂

[thick heron]

Put in your guesses for how accurate the GRS position is.

And how big it will be.

[somber stratus]

lol

[atomic briar]

Damn that image is so clean

From where is it?

[thick heron]

It's a simulation from WinJUPOS.

[atomic briar]

Oh

[heavy mirage]

baaa

jupiter and io, in daylight with 807nm

[somber stratus]

AS!3 stitching is powerful in this one

also, you got the massive barge

[white prawn]

Dodge dangit that barge eludes me.

[heavy mirage]

Mercury

[livid sierra]

Let’s go

Nice construction

I had mine like this when I imaged Mercury

[heavy mirage]

The neighbors were prolly like "this guy is on crack"

[livid sierra]

Yea lol

Your place looks so good though

Nice low horizon, not many buildings around

I reckon the grass causes some dew issues in the morning though?

[heavy mirage]

Yeah, it does. But it's not a problem later in the summer

I'm lucky to have an open field out in my backyard basically

[safe compass]

I'm not so lucky with my backyard

[livid sierra]

Yeah that looks amazing

How far from your house is it?

[heavy mirage]

well, it's literally like right outside the backyard. Maybe 50 meters

This video gives a good idea

[safe compass]

thats so good, my backyard is only surrounded by high bushes

[livid sierra]

Ah shit dude that’s so awesome

[somber stratus]

That’s pretty cool

[livid sierra]

What do you use to get your dob level on that grass?

[heavy mirage]

just a platform with screws

Works like a charm lol

[heavy mirage]

Yeah! I used to set up in my backyard, but then a year later I had an idea to move out there

[livid sierra]

Ooh very nice

You made that yourself?

[cursive inlet]

Bruh im tweakinnn of thaat lsd

Lsd

I am one

With the

Cosmos

[livid sierra]

Loool never thought you'd be doing lsd

Go do some imaging now kek

[thick heron]

Who needs good seeing when there is LSD?

[sharp ridge]

Ch4 saturn looks so trippy

[thick heron]

Try UV

[livid sierra]

Hmmm maybe I should get a CH4 filter after all

Idk tho

[sharp ridge]

Unfortunately don't have one, up to Tom and Duif

Doing color captures

Seeing good 8/10

[livid sierra]

Look nice af

[livid sierra]

Lol. But what's it good for

[thick heron]

For fun.

[livid sierra]

Alr I'll do a UV capture on Monday

Jk I probably won't

[thick heron]

Duif confirmed to be anti-fun.

[sharp ridge]

Pretty decent

[livid sierra]

What alt?

[cursive inlet]

I wish I could but it was partly cloudy

But the clouds are so beutifull

And nature so wonderfull

You know

Usually I would be angry at clouds

But its not ok to be angry about anything

Maybe its ok

But only when its ok

[livid sierra]

That's the spirit ma boi

[heavy mirage]

Yeah, I made it with my dad

We made a small stencil of one of the triangle edges, then used a router to cut it out on plywood with the stencil as a guide

The screw itself is basically just a nut and a long screw, everything else was 3d printed

[somber stratus]

47

based off time stamp

tonight's UV

[steep apex]

Could right now be the best for imaging the shadow divisions?

[thick heron]

For what?

[heavy mirage]

Does this look like anti fun
#1019937457095065731 message

[thick heron]

Falling in that nearby hole would be anti-fun.

[steep apex]

Saturn

No, it’ll show more next year

[thick heron]

The shadow will be thinner next year so the gaps will be harder to resolve.

[livid sierra]

Never say never

[thick heron]

I didn’t.

[heavy mirage]

Geez you guys are fussy

Lmao

[livid sierra]

Nah it's all jokes

Everyone knows planetary photographers have the best humor

[thick heron]

Funny joke.

[livid sierra]

See

What is better, a 6" newton or a 127 mak?

[livid sierra]

Depends on how you look at it

6” has a bigger aperture

But mak has a longer focal length

[hasty hull]

Aperture probably more helpful because it can support longer FLs when you add barlows

[livid sierra]

Yup, true

[cloud copper]

The 6" has 1400

So its good ig

You felt the universe inside you? 😏

[atomic briar]

Yes and it was a good experience lol, not in the meaning you probably ment but damn that was the craziest piss i ever had

[cursive inlet]

Nice

Lol

[barren dune]

I had a psilocybin experience where at my peak a freind showed me a image of the milky way he shot an insane mosaic and I just thought of how beautiful the universe is and how amazing and rare life is.

Any idea please?
My dslr is a cheap eos 4000d.
I can’t find anything in settings Thanks in advance.

My 12" arrives tomorrow, I hope

Best week for the 12" to arrive, I have work off Thursday and Friday, and I don't have a college class, so it will be time to capture Jupiter

[candid flare]

There's a dial that can allows you to do a video in manual mode

[livid sierra]

Imaged Saturn from a parking lot just now

Just got done putting everything back in the car

Seeing looked pretty good for 15-20° alt

On the moon too which was at 11° but I just did some visual on it

[uncut glade]

Bugs are eating me alive but I’m finally back out and imaging

Any idea what could be causing those artifacts along the top right? It’s like a second limb is appearing lol

Nevermind it was focus

💀💀

[heavy mirage]

Finally getting some meaningful UV data... still using the a cheap #47 + uv/ir cut, but I'm happy to finally getting some details

[somber stratus]

Details match what I got last night too.

Nice stuff

[heavy mirage]

Thanks!

[somber stratus]

one of the UV's for reference

obviously OP seeing, but can see it matches

[heavy mirage]

Awesome!

I wanna get an actual uv filter for next time lol

[heavy mirage]

You used a color camera right?

[somber stratus]

No, 462MM

OSC cams are inefficient

25% as efficient to be specific

[heavy mirage]

Right, I was just wondering why it's grayscale but that make sense

[livid sierra]

Second Saturn of the year, quite a big improvement over last attempt

[heavy mirage]

Very nice

[sharp ridge]

very nice

[fading plume]

very nice

[livid sierra]

Very thanks

[cloud copper]

Guys, what should I buy:
-Mars-c
-Mars-c II
-Ceres-c

[livid sierra]

From those three I’d say Mars-C II probably

Or Mars-C

Or Neptune-C II

[cloud copper]

Is mars c II better than mars c

I saw that they have diferent sensors

[livid sierra]

Yeah the mars-c ii is the 662, kind of the followup of the 462

[cloud copper]

But is the 662 better at planetary than 462

?

[livid sierra]

Probably about the same

Don’t think it matters that much which one you get

464 is a bit different tho

Bigger fov

And different qe

[steep apex]

When is the next time this storm will happen on Saturn?

[livid sierra]

Let me check my calendar

[thick heron]

Those storms are known as Great White Spots and usually happen every 27-30 years. The last one happened 12 years ago and earlier than the pattern suggested so who knows?

Past GWS have alternated between a stronger storm at the equator and a weaker one in the mid-northern hemisphere. Assuming the pattern continues the next one should be at the equator.

There are HST photos of the 1990 GWS. https://esahubble.org/images/opo9011b/

[ruby tartan]

6969

[vapid depot]

Wtf that nearly has the resolution of a ground based system

Hubble?

[somber stratus]

Probs when it had a misaligned mirror

[heavy mirage]

Dang, interpolation worthy? @somber stratus

You can tell how the clouds move. I'm sure interpolation will make something pretty intriguing

[somber stratus]

nah, they are completely different

could make a map though

[heavy mirage]

Hmm

At least the stripe on the bottom is pretty noticeable

[somber stratus]

these are same regions i think, or at least same formation

[thick heron]

So I opened up Google Maps and noticed something odd…

[somber stratus]

New discovery ❗

[heavy mirage]

Lol what exactly? @thick heron

[coarse aspen]

huh

you see it right?

[heavy mirage]

Ah

Lol

North Atlantic

WhyM

[somber stratus]

Lmao

[heavy mirage]

I don't see anything else ??

[thick heron]

Keep looking…

[heavy mirage]

Nice spain

Whats up with that

[coarse aspen]

no thats normal keep looking

[heavy mirage]

Nah bruh Idk

🤣

[coarse aspen]

see anything near the caribbean ?

[heavy mirage]

I found it

In your dreams @somber stratus

God dude you guys make me look dumb lmao

We are a floating garbage patch after all

Can move to the tropics

[thick heron]

Let’s all pool together money for property in the Caribbean.

I’ll throw in $20

[livid sierra]

I'm humble, I'll pitch in $21

[coarse aspen]

I'll donate $22

[hasty hull]

$23 take it or leave it

[thick heron]

You all are making me look bad.

[near quiver]

ill pitch in $25, but anonymously so i dont get people asking me for money

[heavy mirage]

Lol, $20

[near quiver]

you know if enough people pitch in $20 it would actually work

[heavy mirage]

Well, property probably cost around 200k lol

Yikes, just looked on Google it looks like property there is pretty expensive lol

[near quiver]

yeah i mean its all premium stuff

we would be better off getting an observatory in chile

[thick heron]

Tried doing Chilescope a few times for planets in mid-2018 and it was nothing but poor seeing and clouds.

We finally used our credits on the Carina Nebula and the dark skies are OP.

[thick heron]

Change of plans.
I’ll throw in a scope: #🤩-show-us-your-rig message

[heavy mirage]

The views through that must be gnarly

At f4.2

[thick heron]

Imagine M51 looking like a faint photograph under a dark sky.

How it is for planets is TBD.

They are basically glorified DIY projects.

The altitude motor engages with a velcro strap on the bearing.

Ours has worn spots and needs replacing.

[heavy mirage]

Yeah I can imagine! Through my 10" I could slightly make out the spiral arms of m51 but only under good conditions.

[heavy mirage]

Try direct drive!

Prolly expensive af though

Or maybe a tight chain instead of the velcro

But I guess, if it works, it works!

[thick heron]

Hmm… create a new system from scratch with direct drives or $20 Velcro strips…

(We already have new Velcro strips)

[thick heron]

The more pressing question is how will the 25 year old motor system interface with a PC? Certain versions can be upgraded to support PC control, but ours is too old for it.

[heavy mirage]

Haha, like I said if it ain't broke, dont fix it lol But I'm sure that overtime upgrades will be worth it

Looks like you'll need the manual to those motor drivers to see how they interact

[heavy mirage]

above average seeing, 20 degrees alt

[cursive inlet]

Should I get up at 4 am for Saturn? Would be my first time imaging it.

[heavy mirage]

It's the best, just for the experience

[sharp ridge]

early morning looking at saturn is the most peaceful experience fr

[vapid depot]

saturn just floating there at 200-300x with good seeing is something all should experience

[ruby tartan]

Is that 'Oumuamua?

[somber stratus]

not when its cold

3am ~August Jupiter slaps though.

[thick heron]

Peace is a mosquito buzzing my ear early in the morning. 🦟

[sharp ridge]

collimation ok? Hope i dont become atreus 2.0

[sharp ridge]

you get used to it

[thick heron]

What did he do?

[sharp ridge]

he has collimation issues

hes famous because of that

Tom knows i think

[thick heron]

Well, I have to collimate after every slew or after a couple hours of tracking.

I think my EdgeHD14’s primary mirror isn’t properly bonded.

Even with the secondary cranked down tight it’s way out after a flip. 💀

[somber stratus]

no

way off

[somber stratus]

@barren dune

[barren dune]

@sharp ridge no

I can help you when i get home

At work rn

[cloud copper]

Order placed! Couldnt buy mars-c, it was a bit too expensive

[steep apex]

Is it worth it or is it too bright? The ISS will be at magnitude -3

[safe compass]

A little too bright to notice possibly, I'd give it a shot if the night is also clear. That case you get to shoot something if you kiss iss

[steep apex]

Thanks!

[lunar hamlet]

@somber stratus you should do an animation of Venus like you’ve done before but in colour

[fossil schooner]

i bought a can of bug spray just because of this

[thick heron]

Bug spray is standard here for any night over 70 degrees, but sometimes it is not enough and I also need a Thermacell next to me.

[fossil schooner]

sounds rough

[thick heron]

The worst part is when they sneak in the house.

[coarse aspen]

mosquito repellent doesnt work for me

they still bite

citronella candle helps but theres still mosquitoes

[fossil schooner]

rate my seeing out of ten

seemed pretty bad tonight

[ashen siren]

7/10

[fading plume]

Please get an ADC

Also, imaging Venus at night. Not based.

[heavy mirage]

Getting somewhere.. I need to get a mono camera

[livid sierra]

You are using an IR cut with the w47 yes?

[heavy mirage]

Yeah, thats right

Oh, prolly should do IR cut rather than Uv/ir cut

[livid sierra]

Depends what uvir cut you are using

[somber stratus]

6 perhaps

[vapid depot]

Idk how badly compressed this gets through the cord but I reckon this was an 8/10 seeing not sure

I just use astrospheric it said above avg to excellent

[somber stratus]

6-7

[vapid depot]

And the result

[vapid depot]

Jupiter from the same night , don’t think I ever posted this anywhere 😮

[heavy mirage]

I used optolongs, it has a bit of transmission under 400nm but not sure if it's good enough for this purpose

[white prawn]

You're not using a DSLR for those images, eh.

[livid sierra]

Ah, do you know how much exactly?

ZWO cuts at 400nm which wasn’t enough. PO uvir cut cuts at 380nm, which is significantly better

[heavy mirage]

Looks like just over 390

[livid sierra]

Can I have some of your UV data maybe?

[vapid depot]

Asi 120mc-s. Trusty old thing that usually guides my dso setup

I thought it randomly broke one night but it was my asi 533’s usb outs lmao

Didn’t even snag anything, and the securing pins came out of the 533 when I went to plug-in the 120 again 😂

[heavy mirage]

Yeah definitely, the seeing wasn't great tbh during my runs but I'll send them once I get home

[vapid depot]

you ever use a 4x barlow before ?@heavy mirage

[heavy mirage]

Noo, but I've done 2x and 3x together for 6x
