yes

lean hearth
#

what planetary camera?

sharp ridge
#

uranus-c

lean hearth
#

That was the 1 I was thinking of buying

#

it’s a nice one and isn’t to crazy costly either

sharp ridge
#

Im also considering the hubble ul16 with a triangulum astro eq base - only 60lbs for the scope, though still planned on the skywatcher

fading plume
#

just imaged mars. feels off from stellarium?

#

also mars has rings confirmed

sharp ridge
lean hearth
#

sometimes Stellarium might not always be 100% accurate

fading plume
cursive inlet
#

Yeah but I have noticed that the mobile version of stellarium is spot on

sharp ridge
#

or make your own ig

fading plume
#

oh no complicated planetary stuff

cursive inlet
#

@fading plume what rig you use for planetary?

fading plume
#

8" dob with uranus C

cursive inlet
#

Nice

fading plume
#

and epic seeing cooloutoffocus

cursive inlet
#

8” dob gang 💪

lean hearth
#

Uranus c and 16” dog would be a healthy planetary rig

fading plume
cursive inlet
#

💀

fading plume
#

not from tonight

#

gotta make one for tonight

cursive inlet
#

I haven’t been very lucky with mars this opposition either

sharp ridge
cursive inlet
#

What happened to mars

fading plume
lean hearth
#

Hey @fading plume#585 where is a good place in australia to get the Uranus c as you have one

fading plume
#

player one website

lean hearth
#

Isnt that usd?

fading plume
#

huh

lean hearth
#

Or do they ship internationally

fading plume
#

yes

lean hearth
#

aha

#

thank you

I will buy an optolong UVenus soon

#

Wow, looks realy good!

somber stratus
#

ik it was probably IR685, but unsure of what UV he used here

ruby tartan
#

I also don't know what brand of UV filter he used

#

What about using a ch4 with Venus?

@sharp ridge im looking at a HO 18in goto is only 2k why not just get it with goto. I was looking at a 24 but wasnt to sure if im ready for it. The goto systems they sell are very accurate even at high power

#

The goto option is only 2k*

somber stratus
#

I know a guy who has the 24" goto

#

i think it's fairly accurate but nothing exceptional

barren dune
#

How are his images

#

And is it a hubble optics 24 and goto system

sharp ridge
#
  • no satellite tracking
barren dune
#

I could care less abt iss lol

sharp ridge
#

tho damn 60lbs is so much better for me

sharp ridge
barren dune
#

Strehl 0.95

#

Primary

sharp ridge
barren dune
#

Simply handtrack the iss at 8500mm fl ofc ken lol

sharp ridge
#

I might go for it then

sharp ridge
barren dune
#

Im torn between the 18 and 20

#

It was a joke

#

But yeah im getting mine with goto for sure

sharp ridge
barren dune
#

Yeah i was looking at those

#

They only track not goto

#

My use of an eq plate so far kinda mid

#

Def worth it for dob imagers but i want goto so i can find neptune and uranus easy

sharp ridge
#

tru

#

Man my lunar imaging with an 18 would be nutty

#

My seeing is just ughhh

#

That jup vid is like 9/10

@somber stratus he needs to do lunar

@somber stratus better than my jupos processes lol

Read a lot about the Hubble Optics dobs a few months ago. Haven’t ruled them out yet, but my concern is that their structure is quite spindly and possibly won’t hold collimation well for planetary imaging. The well-loved Obsession UC dobs look more rigid but tend to shift collimation when moving (seen it happen myself on someone’s 18”). At least the HO looks like it has a metal upper cage, which the UCs don’t.

#

Also add $2000 USD for the goto system and shipping costs (maybe around $750 on average).

barren dune
#

process from toms vid that he sent downloaded ran thru pipp then did my normal workflow I envy you tom

barren dune
thick heron
#

Visual observers seem happy with both. Not sure how they hold up for imaging.

#

Haven’t ruled it out yet as a scope I’m interested in. For me it’s partly a question of whether I want to take the chance on a less expensive dob earlier or jump straight to a premium NMT dob later.

barren dune
#

Yeah my gen is all abt instant gratification so im going HO lol. NMT are really beautiful but they take forever to be built and shipped

thick heron
#

No don’t say that it makes me feel old. I’m almost 24.

#

But neither are really close to instant gratification. The HO website says 2 months, but most reports of delivery times I have seen are 3-12 months with most being around 6.

barren dune
#

I shpuld prob start my order now

#

Even then its faster than NMT or Obsession

#

@jolly leaf

somber stratus
#

I mean for both of you, being in Texas, your seeing will support these bigger apertures

#

worth ordering sooner rather than later if you want to catch the next Jup/Saturn season @barren dune

barren dune
#

Yessirrr

#

Want to order it asap

thick heron
#

One thing to investigate is how their motors are attached so I can duplicate it with an OnStep system. That could save ~$1800 USD.

thick heron
#

Looks like their SiTech system basically uses a motor pushed against an azimuth lazy susan and a wire for the altitude.

livid sierra
#

Yall crazy mayn

thick heron
#

We all passed that point long ago.

cursive inlet
#

Is an e-focuser a good idea for planetary?

#

I spend way too much time tinkering the focus knob

sharp ridge
#

also, mars getting smol

cursive inlet
#

Could using a bahtinov mask on a star be viable for planetary?

sharp ridge
#

Not as good

#

also you gotta point to a star and back each time you have to refocus Roblox_MADwithJOY

cursive inlet
#

Thats what I do tho for planets except for Jupiter

#

Focusing on a star is just so much easier

somber stratus
#

Seeing makes it kinda useless in most situations.

thick heron
#

With color, less important.

livid sierra
#

Like it goes back to a certain focus point with the push of a button?

thick heron
#

FireCapture moves it when switching filters.

somber stratus
#

Do you use the active tracking thing in FC? @thick heron

#

i've never used it myself but curious if it's any good

#

I'm referring to the scope control here.

thick heron
#

Make sure to experiment with the reverse settings or it might start moving it away.

somber stratus
#

Interesting. I might have to use it with wifi & synscan app though. Might need some testing

nocturne zinc
somber stratus
#

I use the dynamic ROI thing that moves the ROI with the planet. Uranus-C FOV helps. Can do about 5-10mins without touching controls

#

But i usually have to hair-dryer every couple recordings anyway so the guiding isn't essential - i'd be next to the scope regardless.

thick heron
#

It can be problematic if the directions are 90 degrees off such as up/down moving left/right.

#

I have left the scope unattended for hours at a time with it on.

cloud copper
#

Guys what are some good planetary cameras under 200 usd

somber stratus
#

pretty limited

#

Used 462mc, 224mc

cloud copper
#

Didnt find any of thoes used ://

#

I live in romania and astrophotography is not that popular on secondhand websites

cloud copper
thick heron
#

Svbony SV305 uses the IMX290 and is $143. It appears to be a color camera.

#

Keep in mind it is a USB 2 camera.

hasty hull
#

Yeah I’ve used it and was locked at 23 fps (max res bc I am untracked). It was a huge pain

fading plume
#

Sv305 pro has usb 3

thick heron
#

Pro is $193 USD, so depends on how far @cloud copper is willing to stretch the budget.

#

Shipping for the goto system is only 55

#

Swank

#

Total been calculating its looking around 6,379 for my add ons

#

So overall not bad

somber stratus
#

18"?

barren dune
#

Ahh 870 us shipping brings it to 7,249

#

Im like a few hrs away from HO at most

#

I will drive and pick it up myself 🤣

thick heron
#

They ship from China.

barren dune
#

What the actual F-

#

Frick 👍

#

Thats why its like 40 to ship to some parts of asia

thick heron
#

Had the same idea when discovering them a few months ago.

cursive inlet
#

Might have a chance to try the w47 on Venus in a few hours

hasty hull
#

Hype

#

I have one of those I’m pretty sure

#

Venus is smol rn so I imagine it’ll be hard to get detail currently

cursive inlet
#

Damn I was so exited but clouds stayed on the horizon after sunset

#

Tomorrow should be clear though

cursive inlet
#

Got some decent looking Mars data, considering its at 9.8" now

cursive inlet
#

Mars last night. 9.6 arcseconds now

#

And in IR685

#

Aight ima try Venus again in 30 min. Im hoping to get some detail in UV

cursive inlet
#

Yess ok I have the data

cursive inlet
#

YESSSS pepeHype pepeHype pepeHype pepeHype pepeHype pepeHype pepeHype pepeHype

#

Its minimal but its definently there

#

white polar regions

somber stratus
#

what UV filter was this

cursive inlet
#

W47 with the IR block

#

I mean technically its half violet and half uv

#

but still

#

Im so happy

#

I captured color and IR850 too, ima process those later

#

I mean for the current size of Venus its pretty decent

proper oyster
#

I never tried any filter during all the time i used a telescope idk how big of difference they make and what they do

somber stratus
#

Most IR-cut filters are also UV-cut

cursive inlet
#

The astronomik IR block lets a bit of UV through

#

its why I bought it

somber stratus
#

interesting, didn't know that

cursive inlet
somber stratus
#

what about this as an alternative. Astronomik Luminance filters, but the L-1 variant

#

allows 370nm+

#

actually it's near the same

#

never mind

cursive inlet
#

Doesnt really matter with the W47 tho

#

it ends at about 385

#

Also the 462 has a strong sensitivity to IR so there might be some IR leak with L-1

#

Anyways its almost the same as you said

#

looks pretty decent for now

cursive inlet
#

color data

cursive inlet
#

very suble detail in IR850

hasty hull
#

What was the altitude?

cursive inlet
hasty hull
#

Crazy impressive shot

#

what did the seeing look like

cursive inlet
#

I can send you a vid of the raw color vid

#

wait maybe I can make a gif or smth

hasty hull
#

Was this with the 8” dob

cursive inlet
#

yeah

hasty hull
#

Epic

#

Found my stuff, this inspires me to try

#

@cursive inlet what filter is threaded closer to the cam, w47 or IRcut?

cursive inlet
#

I just screw the w47 in first then the ir block

#

Seeing wasn't very good

#

adc adjustment is a little off, I was rushing everything bcs I couldnt feel my hands

fading plume
#

How do you go about focusing when stuff is having this bad seeing? Focus on other stars or something?

cursive inlet
fading plume
#

Ah nice. That’s what I’ve been doing but never had good results. Maybe my seeing is just too bad lol

cursive inlet
somber stratus
#

subtle detail on the limb

cursive inlet
#

Working on the IR(g)uv final image, idk if I should use the rgb image for g or the average of the UV and IR

somber stratus
#

try both - won't make much difference. Most people have a SynG = 50% IR, 50% UV

#

i'd go the synthetic route

#

as OSC green channel with have 0 details, whereas a 50/50 blend of UV/IR will have at least some detail

cursive inlet
#

true but my rgb stack is the sharpest. The uv and ir stacks have detail but the shape of the planet is a little wonky.

#

I did the ir850 capture a little late and it has the worst seeing out of the three.

somber stratus
#

best of both

cursive inlet
#

Good idea

cursive inlet
#

Awesome

#

Should I just stick with my ir cut?

cursive inlet
#

Wait didnt you want to get a 585?

onyx garnet
#

But does the 685nm make pictures grey scale

cursive inlet
#

Yeah its infrared

#

Normally you would then use the 685nm shot as luminance for your color shot

onyx garnet
cursive inlet
#

Infrared light is something we can not see, therefore we represent it as grayscale

#

But in infrared, seeing is better sometimes

#

these are some of my images from a few months ago

#

In color the seeing was very bad, but in infrared the seeing was ok and I was able to pull detail

#

then I combined both into a final image

onyx garnet
#

So I shoot a vid with ir cut then the 685nm?

cursive inlet
#

yup

#

you get two images

onyx garnet
#

alr cool, ty

cursive inlet
#

A lot of my images are a combination of a color shot and an infrared shot

#

Like this one

onyx garnet
#

can you show me an example with Jupiter?

#

Ah cool

cursive inlet
#

Sometimes it makes the GRS look a little brighter

onyx garnet
#

With my current set up, should I use a 2x or 3x barlow

cursive inlet
#

2x

#

This is your setup right?

#

2x gets you good sampling

onyx garnet

Also I may as well just get a laptop

somber stratus

Always looks odd

onyx garnet

hm

bitter bough
#

Shot the moon tonight with my IR pass filter. Atmosphere was crazy stable in IR

somber stratus
#

Bare in mind you do lose intrinsic resolution if seeing is good, sure you know this tho

ruby tartan
somber stratus
#

Depends on the scope. I was mainly looking at the colour. OSC cams are green-heavy (RGGB bayer), so when colour balanced, you have to make it "more purple". Here having pure purple means the bayer matrix is transparent - only occurs >850nm.

#

IR685 & 610 longpass appear red/muddy brown

cursive inlet
#

Might have a chance to bag Venus again in an hour

cursive inlet
#

Damn clouds

cursive inlet
#

First totally clear night in a while

livid sierra
#

I see a cloud

cursive inlet
#

Shh

cursive inlet
#

Got another batch of Venus data

#

Decided to sacrifice some fps in uv for higher exposure and less noisy frames

somber stratus
#

how long of an exposure?

cursive inlet
#

Around 17ms

#

60 fps but AutoStakkert is going to have a much easier time selecting the good frames

#

Had some trouble stacking the uv last time since AutoStakkert couldn’t really tell which frames were good

nocturne zinc
#

This is my mars with 9.25 evo and Uranus-C camera.

Any tips? Seeing was pretty bad as always...
Used no barlow.

I do have a 2x barlow and I can make it into 1.5x.

Maybe invest in a 685nm?
What more?

livid sierra
#

Why would you want to turn the 2x into a 1.5x

sharp ridge
near quiver
livid sierra
#

A 1.5x tho

near quiver
#

might be helpful for camera focus

#

My Jupiter and Mars through a C14 and a DSLR any tips

cursive inlet
weary jungle
#

I have a dedicated Astro cam the asi 462 but I haven’t been getting great results with it this is still me best so far

#

Yeah I just think I need a good Barlow because the asi 462 without the Barlow isn’t great and with it it’s lower quality I just think it’s to late quality

cursive inlet
#

Oh sorry didnt read your post correctly

weary jungle
#

No worries

cursive inlet
#

Could you show me an image with the asi 462?

#

I find it hard to believe a dslr outperformes an asi462

#

with a pixel size of 2.9um ur not even that far off with the sampling at f/11

Some nice uv data yesterday evening

cursive inlet
#

Intersting northern band in IR850

somber stratus
#

Yeah possible that's detail

#

@cursive inlet would you send the raws over, if you don't mind. Would like to have a go in prep for this season. Yet to get my own data.

cursive inlet
#

Yeah sure

#

They are a little shaky tho

#

do you want the pipp processed?

somber stratus
#

My Baader Bessel-U is awaiting first light - will be interesting to see how it compares.

#

Yeah just raw stacks, tiffs

#

wanna play with bi-colour stuff

cursive inlet
#

Oh i thought you meant video

#

I think you might want the video cuz it took me some messing around with autostakkert to get the stacks right

somber stratus
#

Yeah, i'm sure you know how to stack properly, don't need to redo that. More just wanting to play with different % combinations of IR & UV as per synthetic green

#

Ok

#

sure

cursive inlet
#

You don't mind waiting abt 10 mins? The files need to upload

somber stratus
#

yeah np

cursive inlet
somber stratus
#

ty

#

what camera was this again?

cursive inlet
#

asi462 color

somber stratus
#

ok, so i need to debayer then

#

or at least the UV

cursive inlet
#

But I converted everything to mono in pipp

somber stratus
#

ty

#

ok

#

nvm then

cursive inlet
#

For UV i only used the blue channel to convert to mono

somber stratus
#

I wouldn't do that imho as the other channels do respond to UV wavelengths

#

albeit much less

#

I'd debayer, then convert to mono using all channels

cursive inlet
#

Hmm idk I do everything in pipp and when I create a mono from all channels I need to bring the gain way up for the video to get to 60% histo

#

More noise

somber stratus
#

not sure why that's the case

#

Idk, seems kinda inefficient to be throwing 75% of the pixels in the bayer matrix, even if the response is poor.

cursive inlet
somber stratus
#

ah

#

sure

#

thought it would be a higher % on the others ngl

#

yeah, just blue is fine

cursive inlet
somber stratus
#

You sir need the 462MM

cursive inlet
#

I guess Venus would be much better with a mono

somber stratus
#

Certainly. IR is fine with the MC as the bayer matrix becomes transparent past 850nm

cursive inlet
#

Still with a mono i'd need to buy a lot more kit

somber stratus
#

But UV/Blue is very inefficient

somber stratus
cursive inlet
#

filters wheels and RGB filters

somber stratus
#

You do exact same as you've done with the MC

#

ah

#

i'm just referring to UV-IR bicolour Venus imaging here

#

Dont need normal RGB filters

cursive inlet
#

I mean yeah I could do color work with the osc and venus with the mono

somber stratus
#

yup

#

that's what i do with my Uranus-C & 462MM

cursive inlet
#

but I aint buying a camera for one planet 🤣

somber stratus
#

Uranus/Neptune & CH4 imaging with 462MM, plus Venus ofc

#

lmao

cursive inlet
#

Perhaps someday when I upgrade to a 12 inch

somber stratus
#

then it'd be worth it

cursive inlet
#

Yeah, I think with 8" of aperture and a color cam, plus Venus being so small rn, the results are decent, I'm pretty happy atleast

somber stratus
#

What exp time were you using on the UV captures out of curiosity?

cursive inlet
#

I dont remember

#

hold maybe its written somewhere in the file data

fading plume
#

It should be in the camera settings text file

cursive inlet
cursive inlet
#

Dunno if the longer exposure was worth it though

somber stratus
#

Not too bad i suppose

cursive inlet
#

Still the most detail I'm able to pull out now is a darker equatorial region

somber stratus
#

not sure if you also got those two dark regions

cursive inlet
#

Hmm

somber stratus
#

this is just wavelets

cursive inlet
#

What percent did you stack?

somber stratus
#

5%

#

30% for UV, but yet to look at that

cursive inlet
#

Yeah you need more for the IR

#

The seeing is too bad

somber stratus
#

seems fine with 5

#

if anything you stack a lower % when seeing is bad

#

hence 5%

cursive inlet
#

Yeah but those spots aren’t real

#

And you have same strange things north on the terminator

somber stratus
#

why would they not be real?

#

stacking artefacts?

#

dont think so

#

If anything you should yield these details from stacking a lower %, as the "seeing" is best in these frames

cursive inlet
#

Idk

somber stratus
cursive inlet
#

Idk those spots just dont look like venus cloud formations

somber stratus
#

higher contrast

somber stratus
cursive inlet
somber stratus
#

send me your raw stack

cursive inlet
#

Its dark because sharpening overexposes sometimes

#

so I normalized in autostakkert to 30%

somber stratus
#

sure. What % frames stacked?

cursive inlet
#

30

somber stratus
#

Ok found it. It's the laplace setting. Noise robust.

#

I had it at 4, which made it "align" to the noise. When at 5+ it yields similar result to yours

#

Must be AS!3

cursive inlet
#

Yeah mines set to 5 but idk what it does so I never change it

somber stratus
#

@cursive inlet

cursive inlet
#

👌

#

Looks very good

somber stratus
#

No luminance shenanigans, just the output from Photoshop RGB composition. 50% of each for SynG

#

Honestly surprised how good this is given the raw video

cursive inlet
somber stratus
#

Regi only accepts .tif, not .tiff I think

#

something stupid like that

#

run it through PIPP & save as new tif

cursive inlet
#

Man I should pirate photoshop or smth gimp sucks

somber stratus
#

Single wavelets application in Astrosurface

#

Not too shabby

cursive inlet
#

I've never used astrosurface for planetary

#

which wavelets do I use?

somber stratus
#

I used a mixture of both for the shots above

cursive inlet
#

Wth are those circles

somber stratus
#

But usually you only need the HF (high frequency) for normal planetary

#

I used pretty much all of the processes in the window for the UV one

#

3.8px Decon, max iterations. 2-3px noise prefilter. HF wavelets size 23, strength 99. LF size 22, strength ~30. Gain 0.4, gamma 1.1

#

Tbh it's all in the wavelets. Have to play around to find the best

cursive inlet
somber stratus
#

yeah, went harder 2nd time

cursive inlet
#

Hmm, couldn't really get it quite right

#

@somber stratus you mind if I use your edit for the post? I'll give you credit.

obtuse yew
#

Astrosurface or PixInsight better for sharpening? Do each work well for a specific planet? Both better than Registax?

onyx garnet
#

@cursive inlet quick question
How do you combine ir pass and ir cut data together

cursive inlet
#

Or you can use winjupos

#

winjupos probably works better for Jupiter

onyx garnet
#

what is winjupos

#

Or ask in #🤓-ask-a-nerd

#

Someone will explain it to you

@cursive inlet @somber stratus thoughts? Venus in UV from just now

#

I’m pretty sure that’s detail

#

the raw stack

cursive inlet
#

Great job!

hasty hull
#

Thanks!! Really pleased with this

#

The w47 + IRcut is really nice

cursive inlet
#

Yeah, I love that Venus is getting a lot more attention now

hasty hull
#

Yeah its a really cool target

somber stratus
#

i.e ZWO or such

#

Bc that's basically blue wavelengths if so. I think the one Guga uses has an increased width and includes a touch of UV

hasty hull
cursive inlet

#

Also, normal RGB data. I swear I see something here too

somber stratus
#

Oh i know, just more contrast in UV against Blue

somber stratus
hasty hull
#

Hey nice, reassuring that it’s real detail in there

cursive inlet

#

Seeing was pretty good too. Like 25° altitude

#

Sun was in the process of setting

heavy mirage
#

@cursive inlet For taking images of Venus with w47 + ir cut, do I need some specific brand/manufacturer for the w47? Or can I just buy the lumicon #47 filter/ can I get away with a cheaper TPO #47 filter?

cursive inlet
heavy mirage
#

Ah ok, its just the lumicon is like 50 dollars while the tpo is 10

hasty hull
#

I use the tpo

#

It seems to work

cursive inlet
#

My one cost me 5 euros and works decently

heavy mirage
#

Gotcha. What about the ir cut filter? can I use my optolong uv/ir cut? or should I invest in some other one for this purpose

cursive inlet
heavy mirage
cursive inlet
#

Eh, should be fine

#

Looks like it lets a bit of light through below 400nm

hasty hull
#

@cursive inlet would it be possible to make a nice composite of the RGB and UV data? Or would I also need some IR

cursive inlet
cursive inlet
hasty hull
#

I have one ordered, been out of stock for over 2 months tho IMDYINGBRO

cursive inlet
#

I wouldn't even really worry getting a good shot of Venus now. Its still very small compared to how big it's going to get right before summer.

hasty hull
#

True

#

I’m really excited for morning apparition in October. Something like 42° altitude before the sun rises

cursive inlet
#

Idk just the whole thing with needing special filters of different wavelength to reveal hidden features of the planet makes it one of my favorite targets

heavy mirage
#

Thanks at @cursive inlet and @hasty hull I ordered the tpo filter, excited to try it when I get the chance

hasty hull
#

Good luck, you’ll get some killer images with your rig for sure

yall are making me want to go image venus

hasty hull
#

It’s very fun

ruby tartan
#

My eq5 engines burned out, I won't capture until next month

#

😔

somber stratus
#

some have a lower cut-off so you end up passing more UV, which you want in this case. From what i can tell Astronomik IR-Block & Orion IR-cutting filter are decent. Anything that passes a little below 400nm is optimal - most UV/IR cuts have easily obtainable transmission curves online

#

My Baader Bessel U (~Johnson U here) is waiting for me back home. Just need to pick a weekend to test it out. Should be interesting. This is how it compares to W47+IR cut.

hasty hull
#

Can’t wait to see how that goes

#

How often do certain cloud structures stay on Venus? Would it be much different over the course of a few days?

somber stratus
#

Not in coordination with the surface* as this rotates incredibly slowly

hasty hull
#

Yeah isn’t it tidally locked

somber stratus
#

No, retrograde rotation.

#

Very slow (long period)

#

Day>Year iirc

#

Not sure if that's sidereal or solar day

hasty hull
#

Ooh oops, I should really get to know space better tbh

#

Classes in HS are no good for that and idk where I’ll go after tbh

somber stratus
#

Solar day is 0.5x the year

#

ish

#

So the sun rises twice for any given location in a Venusian year

#

But a star / constellation stays visible all year (or at least only sets/rises once)

hasty hull
#

That’s really wacky

#

Pretty neat

#

Venus night side imaging is possible right? I believe I’ve seen images of it using some super super deep IR

#

Like the heat signature or something

somber stratus
#

yeah, theres a window at 1.01 microns

#

= 1010nm

hasty hull
#

It is actual surface features right? Not just more cloud

somber stratus
#

Yeah, thermal re-radiation from the surface. Darker regions in images are higher up (colder)

hasty hull
#

Oh wow

wispy pagoda
#

I'll probably try a bit of jupiter and venus

#

And there's a io transit!

#

Interestingly Hubble imaged the same time as me on Nov 12 2022, good way to compare

hasty hull
#

That is really really cool

livid sierra
#

So for Venus with detail and colours you need the W47, IR block and 850nm IR pass if I understand it correctly?

#

Will add those to my wishlist if so

#

And the UV/IR cut of course but I already have that one

somber stratus
#

Depends on altitude & seeing

livid sierra
#

@somber stratus could I use the 685 for normal IR stuff too? Like would it be better to have just the 685 or to have both a 610 and an 850 and no 685?

somber stratus

610 & IR850 imho

@ruby tartan what program did you use to combine/mix the color channels?

Are there any tutorials for combining the layers in gimp? I did a bit of searching and I couldn’t find anything

cursive inlet
# hasty hull Are there any tutorials for combining the layers in gimp? I did a bit of searchi...

I frequently get asked about how to combine three mono images into one RGB using GIMP. This article addresses how to do just that. I assume you have three mono images, one for each filter of red, blue, and green. Note On Update There is a better approach that you can use, that doesn't involve

hasty hull
cursive inlet
#

The order doesn't actually matter

#

you just have to set each layer's blend mode to screen

#

and after that you just play around with levels until your colors are balanced

#

Btw you also have to create the green channel with a 50 percent blend of the uv and rgb

ruby tartan
#

Try using R from RGB and UV, R=R, G=R+UV and UV=B

ruby tartan
hasty hull
#

also thank you guys for the help

#

ive never done something like this before so i am completely clueless tbh

cursive inlet
hasty hull
#

looking funky

#

alright im gonna try and make that green channel now

cursive inlet
#

You set your rgb stack to red right?

hasty hull
#

probably not

cursive inlet
#

Actually I wouldn't colorize the layers yet. To create the green channel you need to duplicate the mono rgb and uv layers and then combine them. After that you colorize

hasty hull
cursive inlet
#

Sorry this probably sounds pretty confusing

#

I would show you but im not at home rn

hasty hull
#

its alright haha, im here to learn these things

cursive inlet
#

Leave it the way it was just press merge

#

And now you can colorize

#

Also btw when you are colorizing you should adjust the lightness slider so the layer isnt overexposed

somber stratus

Hubble has tons of these

barren dune
#

Also exposures are usually on the order of ~10-30sec so you'd have motion blur if it was a minor moon

cursive inlet
#

Can’t wait for Tom to have a go at Venus

somber stratus
#

Yeah, me too buddy

#

Just need to schedule a weekend to go back home to my scope

#

at Uni currently

livid sierra
#

Is there any use to imaging Venus by daylight? With the w47, ir block and ir filters and all too? Or at that point is it better to just use an ir filter. And only go for UV when it’s actually like dark

somber stratus
#

Theoretically, it should be doable. IR certainly is as i've done it myself. UV imaging is slightly more difficult as the sky brightness will limit exposures to something much shorter than otherwise used. You have to prevent overexposure. Using shorter exposures in UV especially will degrade image quality as per noise.

#

Not to mention daytime seeing is atrocious in most cases

#

Worth a try, but dont expect much

#

Some images i've seen on astrobin were taken ~1 hour before sunset. This is fine & clearly works but i wouldn't try in the mid-afternoon

livid sierra
#

I see

somber stratus
#

But tbh daytime seeing & then higher altitude of the planet cancel each other out.

livid sierra
#

I think I might actually just stick with buying the IR850 and 610 next for now. Maybe I’ll buy the IR block and W47 later or next year. Kinda gotta watch my money currently, for summer break too ofc lol

#

Can use the 850 for Venus still and the 610 for other… stuff

#

Moon & shii

#

Using the 850 on Venus just shows some cloud detail right? But won’t give any nice colours like combining it with UV will?

somber stratus
#

Seeing is errrr. Yeah…

cursive inlet
somber stratus
#

Can see cloud structure on live view though. Phone vid above doesn’t do justice

My data wasn’t all that good either but the end result was decent. I am eager to see your image once you process it!

Have got the main OTA in-shadow but the back of the secondary is the problem. Impossible to shield without also reducing effective aperture

Did you find it through the finder or GoTo?

somber stratus

Finder scope & altitude marker on the base. Set to 39deg (from stellarium) then just slewed left to right until I saw it

Eh, it’s not a concern, you need to be within about 10deg to cause any type of damage. Having a touch of light on the primary isn’t even an issue. That light won’t focus onto the secondary when it’s coming in from such an extreme angle @livid sierra

  • some sort of filter to darken the view. Moon filter held to your eyes for example. It's too bright otherwise.

You can spot the Galilean moons by eye. You have to find a street post or similar to eclipse Jupiter. Callisto & Ganymede are easiest.
