Subject: Re: Jupiter animation

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

Hello all

I tried for the first time to create a Jupiter animation.

The seeing was not that great but at least the shadow and disc of IO are visible in the final animation.

Please find the animation and the technical details here:
