Jupiter 10May2017 - my 1st images from ASI120MM-S

[geoflewis]

Hi all,

After a few abortive attempts due to very poor seeing, with my new Astronomik RGB filters and the ASI120MM-S camara, on 10 May I got sufficiently good seeing for a series of capture runs using FC. Seeing deterioated as Jupiter gained altitude, but I got 3 runs at it. Scope is C14XLT, with 2" x2 Powermate and the ADC in train to mitigate atmospheric dispersion. Below is the first image from the series displayed with north up.

Below is an annotated composite of the 3 image runs displayed as south up, showing rotation over period of approximately 38 minutes, though excluding the effect of de-rotation data was actually captured over a 50 minute period.

Each image comprises 25% of 4000 frames per run of 3xR + 3xG and 25% of 3000 frames 3xB. Data stacked in AS3, wavelets in R6, derotated in WinJupos, final sharpening, denoise, saturation and colour balance in ImagesPlus and PS(CS2).

I hope that you like them, but as always comments and suggestions are very welcome.

Regards, Geof

Nice result!

Thanks Michael, I was losing my mind the last few weeks wondering whether I would ever get usable data with the continuous rubbish seeing we've been experiencing.....

Thanks Angie, I like to see the processed images from a single session side by side, so glad that you liked them. It always amazes me seeing just how rapidy Jupiter rotates. Geof
