Jupiter with GRS, Ganymede and Europa (9/10/22)

[Kon]

It seems that seeing was very weird last night. No jet stream but awful to get focus. This was my best 3 captures around 1230 UTC before it deteriorated completely. I think I have got some details on Ganymede in the third picture (I have also resized it in the 4th, 150%); Europa is appearing as a white dot on the surface (no shadow yet). Europa approaching for the transit but by the time the shadow was casting I could not get any focus at all. Are my whites ok, I seem to vary depending on the light (I think the adaptive lightness is messing me around). 8" Dob manual, asi462mc, 2.5xTV powermate.

Very nicely captured, despite the issues

I was hoping to also capture the shadow as it was developing but the weather didn't play ball, but a nice bonus of the two moons.

I feel your pain keep hoping for a consistent sharp run. Instead of just moments during a capture. This night looked promising. But nope still atmospheric or thermal events going on for the entire duration. I see it wasn't just me then. I wonder if falling temperatures were the reason? affecting some locations more than others?  Despite all that some good detail Kon. I think your colours look good. Whites look good

Very nice yes seems to be some surface details on Ganymede, great work with an 8” manual dob

Thanks Neil (and for the feedback on the colour balance). I noticed that while the Moon was out the sky had a milky like appearance but no obvious clouds, so something was going on with transparency or at least make the atmosphere unstable. On the other hand, Mars was a lot easier to focus, I could even see the polar caps on the capture screen.

Thank you. I was very pleased to see it popping in registax even with mild wavelets. I am very pleased on how my Dob is performing, I never thought I could get such details (the upgrade to the asi462 has also helped).

Very impressive images with a manual Dob!

Thanks. I seem to have got the handle of imaging with the manual Dob (and I am aware of my limitations in terms of quality), although I am looking into an EQ platform at some point.
