Saturn and Titan
Back on 28/7/15, had a decent night of seeing so decide to go for a little challenge. That was to image Saturn, but also to get Mimas, Enceladus, Tethys, Dione, Rhea and Titan. Mimas in particular I knew would be a challenge with a QHY5L-II and EdgeHD 925 @ ~f/22. I also planned for 1 hour of collimation, which worked well.
Normally I try to bang out images the weekend after I take them. But this one I decided I would process carefully, and generally take my time with it after the seeing turned out to be decent. As it turned out the next 3 nights were also good, but not quite good enough to get Mimas through the noise.
Filters are IR (RG610), G and B. Saturn is presented in IR IR G B, Titan is IR G B, and Mimas, Enceladus, Tethys, Dione and Rhea are IR monochrome because they were too faint in G and B.
Composite assembled in PS after processing with Autostakkert, Registax, WinJUPOS for many hours.
Finally hit the combined limit of the EdgeHD 925, QHY5L-II and seeing, and im really happy with the result.
Enjoy!
