Hello guys,

My 178mm cool is showing a problem, that did not show up a few months ago. It appears in longer frames and when I take quick frames of moon for example. In my first frames today it's not appeared. After a few frames , I have found an object (an agglomerate) and this problem appeared, what is very strange.

Difference:
Normal frame - 50 gain, frame 2 minutes.
Problematic frame - 300 gain, frame 15 sec. But if I increase the exposure, the problem come out more clearly.

what this could be?
