16 inch f4.5 mirrors from Telescope & Astronomy
I'm looking at building a 16 inch classic Obsession Dob from David Krieg's book (It will be my first telescope). I also want to add tracking and Argo Navis.
I have 2 issues to start with (I'm sure there will be many more to come).
(i) The mirror
Telescope & Astronomy are selling 16 inch f4.5 mirrors they're getting from China for $1800 plus postage. They say the mirrors are the same that they put in GSO scopes and even the meade dobs.
I would be grateful for anyones views on the quality of such mirrors. Being a newbie to this game I figure once my standards get more exacting i can always change the mirror or if I get appeture fever I can build a bigger dob.
(ii) Tracking - I'm looking at the servo cat but is there anyone in australia that makes a drive system suitable for a obsession DOB
Gratful for your views
Regards
Claude
