Common imaging train

Askar SQA106 (M54) + QHY600M + CFW3-L + OAG-M

With Askar's M54 adapter the SQA106 keeps a wide bore right to the camera, which matters for its 55 mm image circle and a full-frame sensor. The full-frame QHY train: SBFL body, the 7×2" CFW3-L and the OAG-M in front. Thread genders at the CFW joints are not published, so those joints are flagged for you to confirm. The SBFL body plus the 7×2" wheel leaves a small gap that QHY's thin rings close.
