M31, The Andromeda Galaxy, take 1. This image will be replaced in a few days once final processing is complete. Another test using the Pentax KX and Skytracker mount. 135mm Carl Zeiss Sonnar @ f/4.5. ISO 800 with didymium filter in place. 80 min exposure consisting of 20 x 4 min subs. The first Skytracker I had was still working pretty well at this time. 60% of the subs could be retained and used.
Darks and biases taken.

If this user has been harassing you, and you shadow-ban them, all their activities on your content will be invisible to everyone except themselves.
They will not know that they have been shadow-banned, and the goal is that eventually they will get bored while having caused no harm, since nobody saw what they posted.
You will remove your shadow-ban on this user, and their comments, messages, etc, will appear again on your content.
