Hello, went out last night to test out a new setup and couldn't get focus for the life of me. The attached picture was as focused as I could get with the scope fully extended. I followed the ZWO set up exactly and had was measured to be 55mm from the flattener glass to the sensor, but im clearly missing something. Scope is an ED127, 3inch .7 reducer/flattener, OAG, filter drawer and ASI2600
