Thanks Rusty,
once again 66.6mm of back focus.

The nose piece on the QHY9 is too long to allow for that.
I need 70mm.

cheers

I have written to a guy called Bern who may have shorter nose pieces available.

see this thread:

QUOTE:
I just got off the phone to Bern at Modern Astronomy and he has a batch of short nose pieces which were made especially for this scenario, i.e:

QHY9 / Protective glass chamber / QHY filter wheel / Nosepiece / Skywatcher reducer.


Maybe he can help?

cheers
Allan
