I’m continuing with the image processing of the March 20 lunar session. This time the subject is the Aristarchus area, with Vallis Schröteri near the terminator.
The images were both acquired with the 355mm F/5 Newtonian and ASI 174MM camera with a Red filter in 6-7/10 seeing conditions. The first shot was acquired at F/20 (and enlarged to 120% in processing), while the second at F/30 (it was resized to 90%). This comparison shows that it is not wise to go too far with the magnification, if the seeing is not close to perfect…
I’m also posting two links from the LPOD site, where Chuck Wood made some scientific comments regarding this interesting region: link 1, link 2.
