[Octane (Humayun)]

Is it possible?

I can't for the life of me work it out.

None of the system charts are any help, either.

I do have a Takahashi 2" adapter of some kind with two thumbscrews; this would require me to put the nosepiece back on the CCD (currently use a Feldstein #6 to mate the CCD to the scope).

Has anyone got this combination working?

If I could pull it off, I'd have an 848mm f/8 system.

I've sent Peter Tan an email with no reply (not unusual, he takes his time) and also just fired one off to Art from TNR hoping to hear something favourable.
