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 KafalisVery 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
Kai Kretzschmar's  28" f/3.1 sets the new standards for large mirrors: This is the future!


... from our neighbors ...

Frédéric Géa und David Vernet   Two 1 m f/3 Dream Dobs with slumped mirrors! More pictures are here and here
Alt-Az   Even more Big Dobs from France


... and from over the big pond

Ed Jones   Inventor of the CHief (catadioptric Herschelian Schiefspiegler), has been made up to 20" f/8
Tom Osypowski    Spica Eyes Telescopes and equatorial platforms
Howard Banich   28" aluminum Dob with tracking
Ross Sackett  Moonsilver single-pole Dobs with elegant finish

.. . . internet communities . . .

The ATM and Observing forum on Astrotreff (german)

... on Cloudynights (english)...
... on Deep Sky Forum (english, dedicated to Visual Deep Sky Observing) ...
... and on Astrosurf (in french).

Getting bored at the telescope? Try this!

You think you have observed everything? Check out the web pages of Steve Gottlieb, Mark Wagner, and Jim Shields
Alvin Huey offers free pdf observing guide books on his webpage faintfuzzies.com
Paul Alsing has a very nice collection of observing sheets of exotic objects.


Many more interesting observing reports can be found by Tom Polakis, Mark Wagner and Ray Cash. Another good source of observing suggestions is the  Yahoo Group AmAstro.


There are many German web pages with observing projects, as for instance those of Stathis Kafalis (Abell PN and exotic stuff)
Peter Surma (with tons of interesting background knowledge about the astrophysics of the object)
Uwe Glahn (in particular galaxies and PN)
Johannes Brachtendorf (interesting small observing projects)


Many more interesting observing projects can be found on the pages of Martin Schönball, Hans-Jürgen Merk, or Daniel Restemeier.
