Rima Ariadeaus, crater Delambre and Mare Tranquillatitis

Stacked image of the mid Lunar terminator region on 04/01/2016 with the craters Delambre (bottom right), rima Ariadeaus (bottom left) and the mare Tranquillatitis (top).

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 (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 image shows the middle lunar region slightly away from the terminator. The rima Ariadeaus is really striking here being interrupted by the lunar terrain. The edge of the Mare Tranquillatitis also shows well here, marking the beginning of more mountainous terrain.
