I need some help -
The combination of my Sky Rover 115 triplet, sky rover flattener/reducer , a CEM70 and a 2600mm highlights a problem I have - the lower left hand corner of my images always seems to have elongated stars.
I need some help in diagnosing the issue. My guess is this could be one or more of these problems:
-Camera tilt (but why only one corner?)
-Backspace from flattener (again, why only one corner)
-Telescope internal alignment
-Camera not being centered in the telescope (focuser installation issue?)
I've attached a sample image showing the problem as well as a flat (if that helps at all).
I'd appreciate any thoughts...
