Description

After a year I visited the Mare Humorum again. I am pleased that this time I was able to work out significantly more details, which I attribute to three factors. First of all, the seeing was not so bad here in Cologne, at least for our standards. Secondly, this time I could stack significantly more frames with 900 out of 10,000 frames and thirdly the noise was probably also lower because I had only worked with a gain of 85. The other recording data are: exposure time 6.6 ms at 66 fps.

With all these geological details in particular, the Mare Humorum is a real eye-catcher for me. A large number of rilles that partially intersect (for example in the crater Gassendi and southwest of the crater Liebig) and cliffs that almost circle the Mare Humorum impact basin.

As always, I look forward to recommendations and harsh criticism.
