OAG or Guidescope? I assume thats a Celestron 9.25 with a focal length of 2350mm. Does it have mirror locks? My guess is you are using an OAG at 2350 FL and the guide star is jumping around due to

My understanding is the flattner goes on the focuser drawtube and the camera attaches to the flattner. At least that is the how the AP and just about every other flattner I’ve seen works… it
