Ptolemaeus, Alphonsus, and Arzachel Craters

            May 21, 2021
Moon 74.7% full

Here is a previously unprocessed photo of three prominent craters familiar to all selenophiles (lunatics?): the trio of (from top to bottom) Ptolemaeus, Alphonsus, and Arzachel. Here they are captured under high-angle illumination from the East (late morning on the Moon), which reduces contrast and makes photography a challenge.

Photographic conditions for this session were challenging, with below average transparency, variable seeing (2.5-3 out of 5) and thin, high clouds. To counteract these difficulties, more images were collected and an IR (infrared passing) filter was used. The best 37% of 17,295 video frames were used to create this photo.

Stacking was done with Auto Stakkert!3. Wavelets and histogram adjustments with Registax 6. Toning, cropping and rotation with Camera RAW and Photoshop CC 2021.
