ATM request for CR150/1200 achromat

["Hans Winkelaar" <hans.winkelaar@12move.nl>]

Hello everyone,

Is there some one who has a Celestron or Skywatcher 150.1200 achromat 6"/f8.
I need it for some testing and evaluation to compare with other 6"
achromats. Where could i purchase one ?

Kind regards

I am currently working on the same project and so far so good.  :)

How about using a diamond saw. I used to do lapidary and that blade would
cut
glass like butter,  then grind off excess on a steel plate with course grit?

Try eBay for cheaper diamond impregnated round steel blades.

Question though,  wouldn't you want to grind off the back first then make
the
mirror?
I would think less chance of distoying the figure. Just a thought.
