God I love astronomy where every purchase is fraught with danger of x not fitting y.
In this particular case my QHY filter wheel needs an adaptor to fit Atik OAG. Atik has kindly provided a system chart
here (which doesnt help).
So apparently I need an adaptor to fit M54(FW side) to fit the off axis guider which has female M-54 threading on both sides.
Experts can correct me if I'm wrong.
My question is where do I get this from?
