Maurolycus, Barocious and Stofler

Stacked image of the Southern Lunar region with the craters Maurolycus, Barocious, Stofler and Faraday. I made a mosaic of frames but I will comment of the best individual frames here as well. Taken on 04/01/2016 (~16:00).

Telescope: SW 150mm F12 Mak-Cass. With a Baader fringe killer filter.

Camera: Canon EOS 550D in 60 frames/s movie crop mode, ISO 400, exposure 1/60s. I took 3 minute recordings for each image (10800 frames).

Processing: Movies were initially processed in Pipp, keeping the best 2000 frames and decompressing them. The decompressed frames were then passed to Registax aligned using 100 points. The best 90% of the frames (using the Registergraph) were kept and stacked. The final image was enhanced by amplifying the first three wavelets by 80, 20, and 5 respectively. The Gamma was reduced to 0.8. Drizzle 2x was also used.

Comments:

This was taken during twilight with the telescope not accurately focused. Even so, I was able to pick out quite a lot of detail here. The high walls of Maurolycus and Stofler create deep shadow that obscures most of the inside of the craters apart from the huge inner peak of Maurolycus, that just dips into the sunlight.
