Big Saturn, Brisbane, 19th April 2012 + Video

Seeing in Brisbane was pretty good on the 19th and the sky was clear for the time being at least but I had to go to night shift I left the 12" Dobsonian set up until the very last minute to get Saturn as high in the sky as possible.

With about 4500 frames with the EOS 600D video set to Faithful picture style, with saturation maxed and contrast minimised (to catch the C ring, which seems to be helped by the Seeliger effect), along with a 5x Powermate and 2x Barlow I managed to get this image. I've left it at original capture size. I am normally heavy handed with processing so I've tried to ease off for this one. Manually tracked as I find it easier to keep it in the frame that way than correcting the tracking when needed.

Video of some Registax frames with the final result here:

Also attached is an image recorded 3 minutes earlier in Landscape Picture Style, heavily processed to bring out activity in the North Equatorial Belt (NEB).

Thanks for looking and feel free to edit it if you like ,
