About this image

We haven't featured the moon in a while, and Davide has recently posted to his observer's page some excellent lunar images. I selected this one, of the region including craters Ptolemaeus, Alphonsus and Arzachel because of the incredible detail it shows.

Davide mentions that the image was taken close to astronomical dawn, when his equipment was completely wet, the plate misted but the Moon at its zenith. He had to dry everything with a cloth and demist the mirror with a 12v field hairdryer.

Even though the seeing was not of the best, he achieved amazing resolution.  Within Ptolemy and Albategino some depressions are clearly visible. Furthermore, the plume in Alfonso and the rimae in it and the fault in Arzachel are present and clearly evident.

The Davy range is a shimmer of beauty and the walls of Herschel appear as if "terraced".  Alpetragius has that central boulder that gives even more a peculiar touch to the scene.
