Askar SQA85 (M54) + QHY268M + CFW3 + OAG-M

Fitted with Askar's M54 adapter the SQA85 presents a wider thread, which is what M54-native cameras and wheels want. QHY's own order is camera → CFW3 → OAG-M, with the short-back-focus (SBFL) body making room for the wheel. QHY does not print the thread on every joint, so the tool flags the joints it cannot check — confirm them on your parts. The QHY OAG-M threads straight onto the M54 output; the short-back-focus body leaves room for the wheel.
