Hi all,

here comes my Jupiter animation ... it's more or less a first time for me as well.
Modest setup : good old Meade LX6 8'' SCT, Unibrain Fire-i color webcam directly in the focal plane, i.e. at f/10)

Natural pixel size, with legend :

2x upsampled :

The colors look a bit special, I tweaked the gains a lot while recording and had to "compensate" for these tweaks before assembling the animation. Ahem...
I suppose I'm slowly getting near to the limit of this low-level 3x7 bit bayer mask camera.

By the way making the anigif was a bit non-straightforward; I've used the Gimp, aligning all my 9 layers manually, then converting to indexed colours (ouch) and exporting as gif...
Do you have better solutions ? Astro IIDC's "Images to aligned movie" had some trouble with the moving satellites or the overprocessed Jupiter, and the alignement was not that fine.

Next time I will also have a closer look at the collimation first.

Cheers,
Malte
