astronomy and atm links . . .
. . . to pages of other telescope makers . . .
These are just a few internet links, which are very useful to get an idea of what can be achieved by ATMs. Much more extensive lists of links can be found on the websites of Stathis Kafalis. Very informative link lists (sorted by topic) can be found on the web pages of Stellafane (very recommended!)
A few pages in German (partly also in English) ...
|Stathis Kafalis A must! Everything about mirror grinding and Dobsonians. Stathis is also a supplier of borofloat mirror blanks and grit.|
|Uwe Glahn 27" aluminum and carbon fiber Dob on EQ platform|
