Jupiter from 21 March

[james_screech]

I've spent a lot of time experimenting a lot with the processing of this image.

Captured 20,000 frame using FireCapture (@30fps), de-rotated in WinJupos, stacked (15,000 frames) in AS!2 (with drizzle) and post processed in FitsWork (removal of drizzle artefacts)  and Photoshop.

Taken with a DFK31AU03.AS through a Celestron 8"SCT AVX and 2.5x Powermate (final focal ratio about f22).

Excellent detail coming through James, well worth the time spent

Nice detail and process in that capture James.   A much bigger stack than I would do, which is typically around 1,500-2000 per channel - though when you add all the frames together in the composite not so far adrift - might be worth some experiment to see if small stacks do improve the definition without a major increase in noise, though quite probably you've already tried!

Lovely detailed image James.

There was a mainly blue grid like pattern over parts of the image.

Very nice James some good detail on show, ive had similar problems using drizzle in as!2 but not on every occasion?

Thank you everyone for the comments.

I always wonder if it will be better to decrease the image size to increase the sharpness or not. The image certainly looks sharper at half size but then am I losing some of the fine detail? I suppose its very much a subjective thing really.
