It took 1 hour just to find and frame.
Needed to bump up the GAIN to 200 and expose for 4 minutes just to see it.
I used the 2018 Astronomy Calendar image as a reference.
Then reduced the GAIN to 100 (BIAS 50)
9 subs at 4 minutes each.
Then the clouds came back.
I was forced to leave in the rock (or whatever it was) otherwise it would have been only 8 subs.
In retrospect, might leave this one to the experts.
