Description

Checking out how the new 12"Truss RC does on Nebula, and first RBG for the scope. 2400mm FL and good guiding numbers on the CEM120, but there was some moon. This is pretty much full APS-C frame. The numbers show significant oversampling on the ASI2600MM, but I tried BIN2 as a test and didn't really notice any difference. Need more testing on that.

There are some green lines right below the object that seem to be some sort of reflection or something. They are sometimes there in different areas of the screen when there is a bright star slightly off screen. And weirdly, only in the green channel. The filter looks clean.
