[ATM] Couder Masks and Zone Testing

["Byron" <byron@astronomygeek.us>]

Well, it has been a year since I first started my 6 inch mirror, and it is
about time I get the darn thing done.  I am sure there is a place in the
archives where this is covered but I would actually like to get back into
the groove of talking with you guys.

I need assistance with designing a Couder mask and testing the zones in my
mirror. It has turned out to be a good mirror and I cant wait to complete my
scope.

Here are mirror stats;

Plate Glass
15cm 5mm inside of the chamfer
F 4.2

I have read some of about creating a Couder mask, but right now I would like
some type of software or anything that will make creating the masks easier.
I can always grasp a greater understanding of it as I go along.

Thanks for any assistance that you can provide.

Byron
