Janssen   Leave a comment

Due south of Mare Nectaris are the southern highlands.  Here is the crater Janssen 115 miles across with its rille, Rima Janssen, 2 miles wide and 85 miles long leading to the crater Fabricius.  I used one alignment point of 256 pixels in Registax 5.  This particular exposure of 437 frames would not hold registration during alignment with multiple alignment points.  Sometimes it ended up Frankensteinian, with bright seams on all the alignment regions.  Once aligned, I went back and used Drizzle to tease out some more detail, then enlarged the image 200% in Photoshop.  Image captured April 19, 2010.
