High Resolution lunar images – October 21, 2019

Scroll down to content

The second lunar imaging session of October, and a frustrating one: lots and lots of fog, and the wind changing direction every 5 minutes or so, making the fog disappear and reappear a few times per hour. The seeing also varied a lot with the changing wind, from 6/10 to some fantastic 9/10 moments!

All of the following shots were acquired with the 355mm Newton and ASI 174MM camera. Some were taken using a Red filter, while others with a Green filter when the seeing allowed.

Copernicus in Green:
