Saturn 23 June 2015

[MarkS]

My first attempt at Saturn this year.

Imaging Source DBK21 camera with 2x Barlow and IR/UV filter on Celestron C11.
1200 frames at 15fps out of 1800 frames stacked in AutoStakkert.  Post processed in Registax then deconvolved.

Saturn was only 20 degrees above the horizon - it's very low this year.

Looks very good to me. Nice shadows on the ring, a bit of banding detail and maybe a hint of the Enke gap on the right.

I would now do a de-rotation in WinJUPOS, it will work some pixel shifting magic to retrieve a little more from the data. I tried to find an explanation of how it knows how much to move where once you have processed the data (no luck though) as I can see if you presented a video to it it has some idea of duration if it has access to the frame rate in the video and the mid-point time and it knows Saturn's rotation rate(s) and direction - but in a processed image it has only the mid-point time (which you have to tell it or use the WinJUPOS file naming convention) and you've chucked away a lot of the frames to get there. But it does work:).

Very nice Mark, your best yet of Saturn I think.
