NOV 25 - MOON 74% - FIRST LUNAR PHOTOS WITH ALTAIR ASTRO 80ED-R

[paulastro]

Following the purchase and delivery of my used Altair Astro 80ED-R on Tuesday, I was eager to try it out on the Moon.   

Visually it was excellent and showed a fine terminator, with the W walls of Cyrilus soon going to fade from view. The terminator from Hypatia going S past Cyrilus to Zagut was particularly fine.  Despite indifferent seeing, the image was very contrasty and sharp with no CA that I could see.

I took some single frames with the Olympus E-M5 Mk11, the best frame shown below, was taken at 00.30, 1/400 sec at 400 asa. There is also a crop from the same frame and the view for the same time from NASA's SVS Moon Phase and Libration Software.
