Hey all,
I was wondering if anyone had any experience with an issue I am facing. My imaging rig consists of a C8 edge HD with the f/7 reducer and an asi294MC pro. Notionally my camera sensor fits just within the supported image circle of the reducer, but I notice the stars are beginning to look elongated even in the centre of the FOV, pointing outwards towards the corners.
My total backfocus distance is 105.3mm and I just recently recollimated the scope so I'm really scratching my head as to how this could be happening.
Any and all input is greatly appreciated
