what planetary camera?
uranus-c
That was the 1 I was thinking of buying
it’s a nice one and isn’t to crazy costly either
Im also considering the hubble ul16 with a triangulum astro eq base - only 60lbs for the scope, though still planned on the skywatcher
its always off, that region partically trippy
sometimes Stellarium might not always be 100% accurate
so how do i get accurate ones?
Yeah but I have noticed that the mobile version of stellarium is spot on
get pic du midi mars and input into winjupos
or make your own ig
oh no complicated planetary stuff
@fading plume what rig you use for planetary?
8" dob with uranus C
Nice
and epic seeing 
8” dob gang 💪
Uranus c and 16” dog would be a healthy planetary rig
best seeing
💀
I haven’t been very lucky with mars this opposition either
aint great as 2020 opposition was looking underneath but its realistic
What happened to mars
Hey @fading plume#585 where is a good place in australia to get the Uranus c as you have one
player one website
Isnt that usd?
huh
Or do they ship internationally
yes
you can make own map in winjupos as its more accurate than wonke stellarium ones
Thats neat
bro that looks like a deformed apple
UL24 💪
i only got ~$4600
UVenus
I will buy an optolong UVenus soon
Image made by Damian Peach using the Pic du Midi, IR and UV, synthetic G
Wow, looks realy good!
was this Optolong UVenus?
ik it was probably IR685, but unsure of what UV he used here
I also don't know what brand of UV filter he used
How do you make those animations?
What about using a ch4 with Venus?
Different filters, image by Antônio Cidadão
- Make a map
- Insert into ephemerides tool "options" tab "Texturing"
- Go to graphics and click "save image sequence"
Thank you! I'll have to try it out
@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*
I know a guy who has the 24" goto
i think it's fairly accurate but nothing exceptional
I dunno if the HO build and mirror quality is that good
- no satellite tracking
I could care less abt iss lol
tho damn 60lbs is so much better for me
ISS is where you can get hofs and apods 

Simply handtrack the iss at 8500mm fl ofc ken lol
I might go for it then
nah, def goto or eq platform
Im torn between the 18 and 20
It was a joke
But yeah im getting mine with goto for sure
https://www.triangulumastro.com/
I assume this is only tracking?
Triangulum Astro offers a smart equatorial platform, called TEPP for deep sky astrophotography with Dobsonian telescopes.
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
tru
Man my lunar imaging with an 18 would be nutty
My seeing is just ughhh
That jup vid is like 9/10
yes, and he hasn't really got to testing it yet. He's in Australia so Mars is too low and small to get anything worth while
Very short lived moment of good seeing here. Literally just these 3 seconds. Altitude was 30°
@somber stratus he needs to do lunar
@somber stratus better than my jupos processes lol
IS THAT JOOL???
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).
process from toms vid that he sent downloaded ran thru pipp then did my normal workflow I envy you tom
yeah I knew shipping would be a pain but I mean for an 18in with good tracking its well worth it imo. and are you saying that Hubble optics might hold colli better than obsession. im not trying to wait 4 years for an 18in obsession lol
Not sure. I think the upper assembly of the Obsession UC not being metal hurts a lot, but it could just be the general lack of structure both have in common.
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.
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
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.
I shpuld prob start my order now
Even then its faster than NMT or Obsession
@jolly leaf
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
One thing to investigate is how their motors are attached so I can duplicate it with an OnStep system. That could save ~$1800 USD.
Looks like their SiTech system basically uses a motor pushed against an azimuth lazy susan and a wire for the altitude.
Yall crazy mayn
We all passed that point long ago.
Is an e-focuser a good idea for planetary?
I spend way too much time tinkering the focus knob
If you mean motorized focuser then yeah you can focus without vibrations and do it remotely
but if you want to autofocus like in dso then nah they wont work
also, mars getting smol
Dang
Could using a bahtinov mask on a star be viable for planetary?
Thats what I do tho for planets except for Jupiter
Focusing on a star is just so much easier
tbh no
Seeing makes it kinda useless in most situations.
Done it both ways, but always go back to electronic. With mono, filters come to focus at different points. Electronic focusers allows you to repeatedly return to those without having to fiddle with the knob every filter change.
With color, less important.
Like it goes back to a certain focus point with the push of a button?
FireCapture moves it when switching filters.
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.
Guiding? It’s great!
Make sure to experiment with the reverse settings or it might start moving it away.
Interesting. I might have to use it with wifi & synscan app though. Might need some testing
Random person: how bad seeing do you have? Me: Yes.
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.
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.
Guys what are some good planetary cameras under 200 usd
Didnt find any of thoes used ://
I live in romania and astrophotography is not that popular on secondhand websites
Do you know any other cameras in that price range, I prefer 150 usd but a bit up is fine
Svbony SV305 uses the IMX290 and is $143. It appears to be a color camera.
Keep in mind it is a USB 2 camera.
Yeah I’ve used it and was locked at 23 fps (max res bc I am untracked). It was a huge pain
Sv305 pro has usb 3
Pro is $193 USD, so depends on how far @cloud copper is willing to stretch the budget.
might as well get a ceres C or asi224mc at that point
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
18"?
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 🤣
They ship from China.
Had the same idea when discovering them a few months ago.
Might have a chance to try the w47 on Venus in a few hours
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
Damn I was so exited but clouds stayed on the horizon after sunset
Tomorrow should be clear though
Got some decent looking Mars data, considering its at 9.8" now
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
Yess ok I have the data
what UV filter was this
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
I never tried any filter during all the time i used a telescope idk how big of difference they make and what they do
how can it be half UV with an UV/IR block? Or it is a specific IR-block only.
Most IR-cut filters are also UV-cut
interesting, didn't know that
what about this as an alternative. Astronomik Luminance filters, but the L-1 variant
allows 370nm+
actually it's near the same
never mind
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
color data
very suble detail in IR850
Really awesome man great job
What was the altitude?
around 10 degrees
Was this with the 8” dob
yeah
Epic
Found my stuff, this inspires me to try
@cursive inlet what filter is threaded closer to the cam, w47 or IRcut?
Doesn't matter probably.
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
How do you go about focusing when stuff is having this bad seeing? Focus on other stars or something?
I focused on Jupiter's moons and then panned over to Venus
Ah nice. That’s what I’ve been doing but never had good results. Maybe my seeing is just too bad lol
Yeah I always do either Jupiter's moons or a random star. It takes long since I do it in between filter changes but it works pretty well for me.
similar to mine back in January
subtle detail on the limb
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
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
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.
Do IR-SynG-UV for the colour. Then turn the OSC (rgb) data to monochrome and use as luminance
best of both
Good idea
Awesome
hey uh did I speak to you that day about my future set up?
Uh yeah I think so
I've noticed that most 685nm planetary pictures are grey scale, but I do wish for coloured photos
Should I just stick with my ir cut?
Wait didnt you want to get a 585?
I do
But does the 685nm make pictures grey scale
Yeah its infrared
Normally you would then use the 685nm shot as luminance for your color shot
Am confused about this. So the end result will still be coloured?
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
alr cool, ty
A lot of my images are a combination of a color shot and an infrared shot
Like this one
Sometimes it makes the GRS look a little brighter
With my current set up, should I use a 2x or 3x barlow
Yes
Could you show me your saturn attempts?
I only really started astro in November and didn't really have a chance to capture Saturn.
u planning on an adc?
In the further future, yes. Rn I don't wish to spend all at once
ok
why is muy stack worse than my single sub 
another frame
Jupiter is difficult to integrate IR onto.
Always looks odd
hm
Shot the moon tonight with my IR pass filter. Atmosphere was crazy stable in IR
What IR filter? Guessing 850nm
Bare in mind you do lose intrinsic resolution if seeing is good, sure you know this tho
Probably ir685, ir850 would have less resolution
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
Might have a chance to bag Venus again in an hour
Damn clouds
First totally clear night in a while
I see a cloud
Shh
Got another batch of Venus data
Decided to sacrifice some fps in uv for higher exposure and less noisy frames
how long of an exposure?
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
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?
A barlow would be helpful.
Why would you want to turn the 2x into a 1.5x
focus on the focus, then capture more and stack like 2-5%
actually you may need more magnification, like 3x or adjusting the backfocus of the 2x
you dont always want more magnification
A 1.5x tho
might be helpful for camera focus
My Jupiter and Mars through a C14 and a DSLR any tips
a little oversharpened
Yeah that’s what I thought I have a Timelapse as well
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
Oh sorry didnt read your post correctly
No worries
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
Do you have a UV/IR Cut or Luminance filter for your ASI462?
Yes I do have a UV/IR cut filter
I will send one in a sec
Some nice uv data yesterday evening

Intersting northern band in IR850
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.
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
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
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
You don't mind waiting abt 10 mins? The files need to upload
yeah np
https://filetransfer.io/data-package/3a0Wl0Ut#link aight here's the IR, gunna send the uv once its done uploading
asi462 color
But I converted everything to mono in pipp
For UV i only used the blue channel to convert to mono
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
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
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.
Idk
ah
sure
thought it would be a higher % on the others ngl
yeah, just blue is fine
https://filetransfer.io/data-package/QHN3Rr2p#link here's the UV
You sir need the 462MM
I guess Venus would be much better with a mono
Certainly. IR is fine with the MC as the bayer matrix becomes transparent past 850nm
Still with a mono i'd need to buy a lot more kit
But UV/Blue is very inefficient
how so
filters wheels and RGB filters
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
I mean yeah I could do color work with the osc and venus with the mono
but I aint buying a camera for one planet 🤣
Perhaps someday when I upgrade to a 12 inch
then it'd be worth it
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
What exp time were you using on the UV captures out of curiosity?
It should be in the camera settings text file
thx
15.91 ms
Dunno if the longer exposure was worth it though
Not too bad i suppose
Still the most detail I'm able to pull out now is a darker equatorial region
Hmm
this is just wavelets
What percent did you stack?
Yeah but those spots aren’t real
And you have same strange things north on the terminator
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
Idk
UV
Idk those spots just dont look like venus cloud formations
higher contrast
it's possible i think. Not sure. I'll restack and see if it's just AS!3 being weird
send me your raw stack
Its dark because sharpening overexposes sometimes
so I normalized in autostakkert to 30%
sure. What % frames stacked?
30
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
Yeah mines set to 5 but idk what it does so I never change it
@cursive inlet
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
Do you know maybe why when I export a tif out of gimp its no longer compatible with registax?
Regi only accepts .tif, not .tiff I think
something stupid like that
run it through PIPP & save as new tif
Man I should pirate photoshop or smth gimp sucks
I used a mixture of both for the shots above
Wth are those circles
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
repro
Tbh it's all in the wavelets. Have to play around to find the best
I think the first iteration was better
yeah, went harder 2nd time
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.
Astrosurface or PixInsight better for sharpening? Do each work well for a specific planet? Both better than Registax?
@cursive inlet quick question
How do you combine ir pass and ir cut data together
You can use gimp. Just align the two images, then what I do is I set the color image overlay mode to color mode and you are done.
Or you can use winjupos
winjupos probably works better for Jupiter
what is winjupos
Im going to bed rn, just look it up.
Or ask in #🤓-ask-a-nerd
Someone will explain it to you
cool
Yeah, don’t have to credit either
All good
Orion spaceprobe telescope untracked Jupiter picture
@cursive inlet @somber stratus thoughts? Venus in UV from just now
I’m pretty sure that’s detail
the raw stack
Definitely seems so
Great job!
Yeah, I love that Venus is getting a lot more attention now
Yeah its a really cool target
Did you use a normal IR cut?
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
“IR Cutoff Filter” from Orion
The difference is probably small though, I’ve seen people get detail with actual blue filters.
Also, normal RGB data. I swear I see something here too
Oh i know, just more contrast in UV against Blue
yeah, looks like a touch of UV. Similar to Guga
Hey nice, reassuring that it’s real detail in there
Interesting. Venus tends to vary in contrast. Forecast is showing a partly cloudy evening tomorrow so I might get a shot.
and the stack if anyone is interested
Seeing was pretty good too. Like 25° altitude
Sun was in the process of setting
@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?
They probably all come from the same factory in China anyway
Ah ok, its just the lumicon is like 50 dollars while the tpo is 10
My one cost me 5 euros and works decently
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
Does it have a transmission graph?
@cursive inlet would it be possible to make a nice composite of the RGB and UV data? Or would I also need some IR
With a w47 you are technicaly shooting somewhere between UV and violet
Yeah you could, your cloud details will be mostly UV though. If you don't have an IR filter I would get one cuz its useful for other planets too.
I have one ordered, been out of stock for over 2 months tho 
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.
True
I’m really excited for morning apparition in October. Something like 42° altitude before the sun rises
Yeah that should be really good
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
Thanks at @cursive inlet and @hasty hull I ordered the tpo filter, excited to try it when I get the chance
Good luck, you’ll get some killer images with your rig for sure
i have trees that make it impossible to image venus from my house
i mean i could but it would be annoying and dangerous
I was shooting through some branches
Awesome
Oh wow that is amazing
yall are making me want to go image venus
It’s very fun
more the UV/IR that makes the difference
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.
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?
yes, features "rotate"
Not in coordination with the surface* as this rotates incredibly slowly
Yeah isn’t it tidally locked
No, retrograde rotation.
Very slow (long period)
Day>Year iirc
Not sure if that's sidereal or solar day
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
Sidereal day
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)
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
It is actual surface features right? Not just more cloud
Yeah, thermal re-radiation from the surface. Darker regions in images are higher up (colder)
Oh wow
So the optolong uvir cut filter is good, but if I find anything even lower would be ideal
Interestingly Hubble imaged the same time as me on Nov 12 2022, good way to compare
That is really really cool
bro better than nasa
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
IR 685 is also an option. Better diffraction limit.
Depends on altitude & seeing
@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?
610 & IR850 imho
which is hubble
wait
i see
thats insane
💀💀💀💀💀💀
Venus rn in some terrible seeing, 45° altitude. Sun was 37° up
Nice shots
No one can beat my seeing rn... this is supposed to be Mars🤣
💀
Venus in UV just now
I use photoshop and do it manually
PS or Gimp works
bro hasn't seen ganymede
Nah I’m talking about the planet
Yk the big round thing in the middle
Yeah
Are there any tutorials for combining the layers in gimp? I did a bit of searching and I couldn’t find anything
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
should i put the UV on top or the RGB?
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
Try using R from RGB and UV, R=R, G=R+UV and UV=B
like i did here
thats probably why this isnt working haha
also thank you guys for the help
ive never done something like this before so i am completely clueless tbh
But dont set the opacity mode to screen when combining two layers into the green channel, just use the normal mode for that
You set your rgb stack to red right?
probably not
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
this is done in the colorize tab right? sry im so clueless lol
No to combine the duplicates of the layers you first make only the layers you want to combine visible, then you set the top layer opacity to 50%, then right click and select merge visible layers.
Sorry this probably sounds pretty confusing
I would show you but im not at home rn
its alright haha, im here to learn these things
which option
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

Better than jwst lol
But jwsp hasn't released the images of uranus yet
I've built out this filter out of my Dslr (Nikon d40) would this improve my planetary images?
ir-uv cut?
You're right, I forgot whether it was Neptune or Uranus that JWST took a photo of
Does anyone have any mercury shots?I never see them. I see more Venus pictures than mercury.
Cause mercury hard to image since it’s right next to the sun
I get that but I just wanna see at least one ok mercury picture that nasa didn’t make
There’s transit pics
Tom got a really really good Mercury a little while back
Look at this AMAZING picture I got of Jupiter and it's four Galilean moons! 
...picture I got from stellarium
@sharp ridge did u notice this
Not critical lol but i think a minor moon of jupiter in the hubble image from nov 12 that u were comparing to urs amazing btw
love Charlie
artefact
Hubble has tons of these
Awww
Also exposures are usually on the order of ~10-30sec so you'd have motion blur if it was a minor moon
Charlie's funny
He has already captured both, but only Neptune has been disclosed.
Definitely discovered aliens so they aren't disclosing it
saw venus for the first time today, it is very small. hopefully ill get to image it soon, but in visual light so its not going to be all that great
Can’t wait for Tom to have a go at Venus
Yeah, me too buddy
Just need to schedule a weekend to go back home to my scope
at Uni currently
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
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
I see
But tbh daytime seeing & then higher altitude of the planet cancel each other out.
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?
I mean I can see a phase, atleast that’s good 😅
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!
Might do a run on Jupiter for the jokes of it
GRS should be visible rn
Man if my backyard was pointed West instead of North I'd be able to image Venus
South-West rather
But it's pointed North-East
A little dim 
That's in UV?
Woah looking gooooood
GRS do be dark
Probably not much difference than Jupiter with a blue filter
Did a uv capture back in November
wow tom really fell off after a few months /s
real
Tom, can you send me those captures you took today?
Raw stacks?
I can in 30mins
@ruby tartan
late season Mars. Moments of usable seeing. 8.5 arcsec
Nice
got this image of jupiter with my p30 lite and my seben 150/1400 newt telescope ant 150X zoom + 3X digital zoom. Stacked 15% of 6000 frames.
Nice
Hot
🥵
Awesome

de ducc has joined uranus c chat
Bruh
lmao
What could be a good x2 barlow for planetary and some visual?
almost any barlow is fine
one of the good quality ones is the celestron x cel barlows
Not true
ok then
A low quality Barlow can ruin your image, invest in a good one
GSO is the minimum, if possible get televue
I got a bst star guider
Celestron X-Cel?
I believe that one is good
ye
The problem with a bad Barlow is that all of the light has to go through it, so it can really mess up your image
Yeah you’ll get some terrible CA with a bad barlow for example
celestron x-cel
Or powermate 2x
Epic style
It’s hilarious watching the seeing drop off when the sun comes out
Did 5 UV captures while it was shaded. Doing IR now but sun is out
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?
Finder scope & altitude marker on the base. Set to 39deg (from stellarium) then just slewed left to right until I saw it
It’s very bright in the finder
Then did daytime align on the hand controller. Tracking kicked in basically. No GoTo slewing needed
Good idea
Bro I’d be scared shitless with sunlight that close near my scope
Falling into the ota even
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
Jupiter one wasn’t great tho
Single, quick wavelets
Hadn’t thought about that. Still freaky thou
Btw are those little balls on the bottom end of your ota handles? To hold it?
While carrying it I mean
No, magnets for balance
Oh you can stick those just onto the side of the ota? What do they weigh a piece?
Is it summer for you?
Looks a lot more warmer
I assure you it isn’t 
Yh I’m used to the cold and I hate it by now I just want spring to come
Still snow here
IR looking spicy @ruby tartan
edge rind is very prominent but nice cloud detail for 850nm
Hmm
Still imaging mate
Going for a Timelapse of the clouds
They rotate about the planet in 3-4 days. Should get two images about 90 mins apart
Clouds should move about 0.5 arcsec
I mean Venus is dropping down so seeing could be a bit meh on the second image. We’ll see
holy moly
What's your camera btw
ZWO ASI462MM (Early-Bird).
Early bird in the sense it lacks the usual DDR3 RAM buffer
Best UV. I'll send after doing some Lunar imaging. Still outside
Stacking Lunar. PC dying. Will have to wait. Also want to have a go myself first 
Wow that's insane
i want a uranus c now holy
But Uranus is a good cam
oh right its in ir
how does the pixel scale compare?
Same pixel size
Not an image, But a video of Jupiter, with three of it's 4 Galilean Moons, Callisto, Europa and Io just about visible.
Canon T3i, 55-200mm lens

The ir sensitivity different is that big?
I would have thought that the higher absolute qe of the uranus c and the larger sensor compensate the lower relative sensitivity in ir
3 x IR @ruby tartan
Gorgeous
If I got enough video like this, is it likely that I could get bands on Jupiter?
4x UV
Sensor size makes no difference. Absolute QE is better in the green part of the spectrum yes, but we're talking IR here
which isn't green
You most likely won't
Jupiter looks overexposed and a dslr+200mm lens isn't very good
Ah okay
Also bayer matrix gets in the way below 850nm. Massive drop in efficiency
Well if you do a mosaic sensor size makes a (big) difference
And when I said absolute qe I meant absolute qe peak (just to say the the difference in the relative graphs is less important)
Idk if I'm clear, sorry but I'm tired af
edge of field has coma in almost all cases so you dont want a massive sensor really.
But you still can try with different settings
also manage to record 100fps nicely at 1080p
laptop suffers in 4K that the Uranus-C
Oh ok
Makes sense
Litterally the worst seeing I've ever seen where I live 
Damn
Just wow
Cant even imagine what you'll be getting in October.
@somber stratus you mentioned Venusian clouds rotate in 3-4 days, wouldn’t it be cool to make an animation of Venus images 3-4 days apart that would show actual structural changes in the clouds not just rotation?
Kinda like Voyager’s blue movie
Correct. Not sure what the exact rotation (circulation?) period is though
varies. We could collectively measure it though
I’ll probably be having some clear weather tomorrow, might be able to get an image.
Silly Venus
UV
@ruby tartan most i could get out of IR. Pushed it to the limit.
colour comp looks quite nice actually with this as R channel. Blue wisps
I'll process later, then I'll send the result
cooked to perfection
I just merged the IR(g)UV
What did I use to process?
Yeah
The usual, I started with astrosurface and finished in photoshop, I used nikcollection, topaz denoise for noise reduction, gausian blur and photoshop sharp
Used topaz denoise from time to time, only when there are those thicker noises, it removes well
The lunar captures, can you send them? It has been a long time since I processed a lunar image.
@somber stratus With your lunar images, any secrets? or is it just seeing conditions
its aperture conditions 
frfr, also winter seeing without ground effect is op
Stack at lowish %. I do 10% to reduce seeing effects. Also use <15ms exposure. Again to “freeze” the seeing sufficiently.
Then the usual - scope cool down, collimation etc
And this 
Well I've got a 16" manual that I don't use anymore, just sitting there really. The 12" RC isn't too good either as it's got a mono DSO train. the 10" Newt is my only scope that's half decent
And you'd be surprised to know that there's a 10" SCT sitting on an old paramount GT1100 that I... cannot get off 
For Lunar, tracking is pretty essential if you’re going deep. Planetary wise you could get away with using the manual 16”
10" it is then, I need to get past WA seeing though.
conditions are questionable.
Yeah Jet stream is rough for you guys down-under
Yessiir
lucky
Guys should I buy a used svbony sv 205 camera ? Its priced at 350 ron = 70 euro
This animation will always blow my mind
whens the best time to image venus? ive been meaning to try it
After sunset rn
nto sure
because obviously venus opposition is way too close to the sun and it would be invisible anyway, like when is the best time
i say half phase
that would make sense, its the furthest from the sun so you can get the best seeing
yes
i've heard (not confirmed though) that a crescent venus can be resolved naked eye
I'd like to learn more about that
Mars from yesterday. Processed super quickly before heading to bed. 8.26” in size
The thinner Venus is, the bigger is it’s apparent size. The best phase I would say is a little less than 50% illumination. It’s pretty big in the sky but theres still enough surface illuminated for detail.
yeah, 40% is the sweet spot
You have to have supreme eyesight
Some birds probably can, dunno about people
- 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.
- dark skies
I reckon they’d be pretty hard to distinguish from the stars tho
Oh btw @thick heron that new WJ update makes derotation such a breeze
No need to adjust every frame one by one anymore
Just adjust 1 and the rest is done automatically it’s amazing
Glad to hear it’s working! Now if only I could utilize it…
I’ve got my eye out for nearby used Obsession Classics and other dobs like it.
@somber stratus how do you color balance your ir g uv Venus images?
I'm having a lot of trouble getting that natural caramel white look
Nothing really
i normalised both (before wavelets) to 65%. I did this upon stacking in AS!3 but PIPP works too. Then applied wavelets
saved
did IR(g)UV combo
then upped the temperature in PS camera raw by about +7
done
hi, im looking for a decently cheap barlow lens for a skywatcher heritage 150p, any suggestions?
ina with 3/5 seeing and 8" dob
NICE
why are you so much better than everybody else
@topaz elk i edited yr pic
built different idk 😎
Mars in IR and a mosaic of Clavius which people are just reacting laughing emojis on in #older_system_pics for some reason
no idea why
Unrelated but you could brighten that Mars a touch
Yeah looking at it on my phone it’s a little dark
Every time I put a surface moon vid through Pipp it never works correctly but when ever I try putting a full disc moon it just puts out images instead of a tracked vid
Set the output mode to avi
And try playing around with your alignment box for the close up footage
And extract your red channel for a bit extra sharpness
I do a lot but even after like 6 tries on one it still didn’t work
How?
Don’t bother with that now you can use siril later
I guess I haven’t tried using siril for lunar yet
You only want to extract the channels after you have processed with registax
Damn, I gotta work with my moon more
I also haven’t used registax for moon, only for planetary
Lol yeah use it
Silly me
before vs after wavelets @lunar hamlet
That’s how I can get ina
yup
@fading plume you use all 6 sliders?
Yea
Just adjust them until they look good. Use the denoise level function sparingly. You might just be able to copy mine lol. It will give you a starting point.
Just roughly the same will work. It really depends on your data getting a good result
But in your screen shots, nothing changes
I just turned the view on and off
Ahh
Thx man, I’ll try that tonight prob
My chances of getting ina just went wayyyy up
There’s a guy in #older_system_pics who posted a Venus image and didn’t know what they were
Clavius, nicely on the terminator
why inverted bruh
Sharper than mine
🛀
whats wrong with clavius
Fym
you said something is not right with this pic
Haha yeah
holy single frame
Looks good
Nice nice. Very sharp
What’s your Barlow again? I’ve been meaning to buy a nice quality one for lunar
Ah nice
Now all I need is the seeing 
Perhaps I’ll get the 3x it’s better suited for my setup.
yeah
Attempted to shoot Venus and Jupiter but clouds started coming in fast
Only got a couple minutes of data, wasn't any good though lol
F
Got this image with some craters but im not that good at processing lunar colse ups. Any tips?
Make sure not to overexpose
While capturing
Apply wavelets
Apply a levels in AS to get correct exposure
I’d aim for something between this one and the other one
