I would STRONGLY recommend going to several large star parties and take
a camera along.

You will see many homebuilt telescopes with ALOT of great ideas. I had
spent many hours looking for telescope making ideas on the web and in a
couple of hours at my first star party I saw more scopes than I had
seen on the web in days.

If anyone knows of sites that have ATM pictures and ideas, I for one as
well as others would love to hear about them.

Good luck with the ATM effort...you won't be disappointed.

Let us know how it turns out.
