Folks,
We've had a couple of nights of half decent seeing this week before the weather reverts back to summer humidity and storms again :D
This is the first effort, having sifted through much of the data and having a messy stab at derotating...note the splodgy Ganymede in the top-left ;) I have some extra frames from before the transit started that I'll try and put up later.
Taken with my C11 EdgeHD / NEQ6 / ASI224MC from my square metre of scope space here in Brisbane.
As always, suggestions/recommendations for improvements welcomed - derotating is a tricky business :help:
Edit: added a second image from one of a short image sequences...no derotation but a little heavy handed wavelet application :screwy: Ganymede is a easier to discern as it's not smudged like in the derotated image, but the details are less clear and it looks...mmm...can't put my finger on it :shrug:
Edit2: added an image from slightly earlier before showing Ganymede on approach to transit and Callisto just sneaking behind. Not de-rotated, just stacked and waveletted.
Cheers,
Dunk
