EFW (5x2") adaptation

lin-thaler

How can I adapt my 071MCPro to the EFW (5x2") with its M54 threads to receive the 55mm backfocus with the ZWO-Adaptors included? I have no idea how to connect..

I don’t think it is possible with the included adapters from the EFW or with the camera. You need a M54-male to M42-male adapter with 1.9mm optical length and another M54-male to M42-female adapter with approx. 16mm of optical length. Camera is 17.5mm + EFW is 19.90mm + M54 to M42 adapter is 1.9mm + M54 to M42 adapter is 16mm = 55.3mm
