Hi group,
my previous question regard of the focuser is decided.
It is the WO.:D Thanks for every one!
Now, I need advice for the mirror cell. This is a 12.5" cass. primary.
The only one available is the GS 12" dob. Need a bit of work and
machining, but should be ok. I want to put the focuser and the
shielding tube to the fan opening. Not sure about securing the mirror,
like the idea of the sct style center flange, but this is a old full thickness
Pyrex mirror!
Any other alternative around for a 12.5" cell?:shrug:
Thanks,
Miklos.
