Anyone using the TS Optics 115/805 Photoline with the 0,8 Reducer for it?
I have elongated stars on one side in the bottom and the top, but ok stars on the other side, when using 55mm working distance (APS-C Sensor).
What is your experience with the scope with that reducer regarding the imageing quality?
Thanks

Also looks like tilt to me. Your star sizes on the right hand side are similar to mine, maybe same type of skies, when I had this scope. Right side looks top-bottom consistent, tilt or sag somewhere.
check the whole-focuser rotation on this scope, those brass holding screws for focuser attachment to the OTA can be loose, and the locking screw if that is the focuser you have on it.
thx, yes same focuser. It was tight, no gaps or movement possible.
TS changed the reducer. We will see
