Ganymede shadow transit 7 April 2015

Played with my collimation a bit earlier and I think it has helped a little.  Quite pleased with this capture

C11 at native f10, ASI120mc camera.  Stacked in AS!2 and cropped in photoshop

I'm trying some with a 2.5 powermate, but not getting the detail 9and focusing is a nightmare as its jumping around like crazy!)

Good capture, but there is a lot of pixalation in the image, around the edges of Jupiter and the moons. I'm no expert but have you RGB aligned the image before further processing?

[Helen]

Thanks I'll take a look (the obs pc does sometimes make things look better than on my study machine, so I'll rework on the study machine tomorrow)

I have that problem as well sometimes. A saved image looks different on two different computers.

Looks like some good data there. I to have similar issues when using a x2.5 Powermate regarding focus and find F10 gives sharper results.

I agree its been a discussion on here in previous posts, there can be a big difference on how an image looks from one monitor to another, especially with colour balance, it seems theres no simple answer to this problem, I try to stick to processing on one pc! BTW good capture Helen maybe a tad bright !
