Believe it or not, this is the first night this year of decent seeing. I was starting to wonder if I'd get to use The Monster at all...

I have many runs to process, I think there are some which will improve on this but it might take a day or so to find them.

Seeing was about 8.5/10 most of the time with momentary improvements to about 9.5/10. The small white polar storms were visible most of the time, and that made things a lot easier as I could use them to focus on. It can be a bit of a viscious circle otherwise - if the seeing is bad then I can't find details to help focus on, so the result gets even worse. So it was nice to find a night of good seeing.

After I had finished imaging at around 6am this morning I popped in an Ep and spent some time visually observing. Ganymede was a nice small disk showing darker spots, and there was still enough good seeing about to get glimpses of lots of surface cloud detail on Jupiter.

This image is the original size, here are the details:

Scope: 13.1" f/5.5 newtonian on a G-11 mount
Camera: PGR firewire Dragonfly Express
640x480 @ 30fps, 16bpp monochrome data
Separate RGB channels, 30 seconds per channel
Registax, Astra Image, GIMP.
