First ever Mars (LRGB and animations)

Post by Menno555 » Mon Sep 14, 2020 10:54 am

Finally Mars became good visible for me, it finally comes above the roofs. I never did capture Mars before, so for a first time I am really pleased with it :D
And learned already 1 thing: the rotation is way faster then I did expect. So, also did 2 (very) short animations: one RGB and one IR.
The image is LRGB (IR) and on purpose a bit "rough" .

2 x 30000 frames IR-Pass, best 5% stacked in AutoStakkert
3 x 30000 frames RGB, best 5% stacked in AutoStakkert

Animations made with the ancient MS GIF Animator

Bortle 8
Meade LX65 8" f/10 ACF OTA
Ioptron CEM25EC mount (no guiding)
Baader IR-Pass filter
Baader IR/UV Cut filter
Zwo ASI385MC

Captured with SharpCap Pro
IR 10,1 ms per frame (110 fps), Gain 210, Offset /Brightness 10, White Bal (B)=95 White Bal (R)=52
RGB 6,7 ms per frame (120 fps), Gain 208, Offset/Brightness 10, White Bal (B)=95 White Bal (R)=52

Processed in Photoshop

Hi Menno,

those are great images – if you are on Facebook then do share them to the SharpCap page :)

I was out late last night and was amazed at just how bright Mars was and how high in the sky. Happy planet hunting season!

Will do Robin!
Have to rethink my Mars approach though: I did sets of 30000 frames at 120 fps and that is around 4.5 minutes per set. But in those 4.5 minutes there already is rather a lot of rotation. And that is now in 1 stack and that is not helping sharpness :( Think that 2 minutes (just above 10000 frames) would do a better job.
And yes, it was my first real view and it really was bright and high.

Hi,

this isn't something I've tried myself, but can't you use WinJUPOS to de-rotate the video before stacking?

Cheers, Robin

Menno

I found this https://www.thelondonastronomer.com/it- ... ry-imaging helpful for getting started with WinJupos. Although the workflow describes using LRGB filters it can be adapted to process multiple colour videos - I have used this to de-rotate and stack 10 SER videos captured with a ZWO ASI120MC. There is also information on maximum suggested video lengths for managing planet rotation.

Menno, it is remarkable how much rotation there is from the first to last frame. Did you use bin1? Seems to me that Bortle 8 isn't so bad. You do capture some pretty amazing images. Are you sure you're not Bortle 3? :shock:

HI Brain.

Thanks! One capture coming up again, a narrowband one from somewhere in Cynus.
Yes, it's bin 1 but I did a two times image enlargement with processing. I did try things with bin 2 and bin 3 but that seems to do nothing other then a smaller image. A 60 second exposure with bin 1,2 or 3 does not make any difference when it comes to brighter or something like that. Maybe cause it's a color camera?
And yes, Bortle 7/8. I am smack in the middle of this, in a dark red zone.
