A few HR lunar images, acquired in good seeing with some very good moments. 355 mm Newtonian, ASI174MM, Green filter.
A 6-image comparison of the well known lunar craters Alphonsus, Arzachel and Ptolemaeus under different illumination. All images are acquired in the last 4 years or so, with a 355 mm Newtonian with either Red or Green filters, and are resized to 50-70% from original.
As always these are of superb quality!
Thank you!
