Hi SBIG team, I just got a used AO-L (serial # 090900309) for my old STL 11002 camera. On the company7 web-site I found a chart below with the AO-L physical dimensions stating that the 2.1" aperture threaded the same as the 2.1" aperture on the camera's accessory plate. However the adapter I got manufactured to connect the STL camera to my telescope's M68 connection seems not to fit the AO-L thread. I know that the camera's aperture is 2.158", is there really a different thread on the AO-L? If so can you please give me the details of the threading on the AO_L? If possible can you give me the drawing details about the 8 threaded holes for different possible bolted connections, in case that I have to get another adapter machined? Thank you & Best regards Christof
