Jupiter + GRS - 19th April

Hi all

This image was taken yesterday morning, 02:52 local time in variable seeing. The GRS is just about at CM, and shows the dark grey material on the West side of the GRS. The white spot leading the NTB outbreak is just past the CM.

The seeing started off horrible at 0130 (3/10 at best) but slowly improved over the next 1.5 hours until it was about 6.5/10 when I packed up at 3am.

I left the scope and laptop setup (while ppmcentre crunched away) and went back to bed, and came back out at 0530 to try and capture Mars before dawn, but a thick fog had rolled in and I couldn't see any stars - let alone a dim Mars in the East. Oh well, maybe next time.

12" newt on EQ6, DMK21AF04 + 5x powermate. 100% gain, 18 gamma, 40 seconds on each channel @ 30fps (1/30s exposure). 500 frames stacked in each channel.

Thanks for looking.
