Truss Telescopes (16" or larger)

Starmaster Telescopes - Optically excellent telescopes.  Rick offers very fast telescopes (f/3.6 and f/3.3) along with the standard f/4.0 to f/4.3.  Zambuto and Lockwood are the primary mirror makers for these telescopes.  I own a 30". Starmaster.

Obsession Telescopes - Very well made telescopes.  If you want one quick, this is the way to go.  Take a look at the UC model, very nice and an 18" UC will fit in the smallest trunk.  They just released the 22" f/4.2 UC and it is very stiff.  They use primarily OMI mirrors.

OMI (Optical Mechanics) EVO-30  - All metal 30" telescope built by OMI.  I played with it at TSP '09.  Very stiff scope.

StarStructure Telescopes - incredible all aluminum "fast" telescopes.  Mainly Zambuto and Kennedy mirrors

Spica Eyes Telescopes - equally incredible all metal "fast" telescopes.  Primary mirrors by Lightholder or Kennedy.

Teeter Telescopes - Excellent custom truss telescopes, specialize in long focal length planet killer Newtonions

Meade truss scopes - Truss scope for those on a budget

Baader Genuine orthoscopics - Apparently the same source as the UO HD orthos, these are very hard to find but...

Baader Classic orthoscopics - They claim that the coatings is better than the BGO and at a price of $74!  Pretty good.  Available here and here.

Glatter Collimation Tools - I use the Blug when I arrive at the site too late to use the Autocollimator.  The accuracy is excellent with my f/4 reflector.

Catseye Collimation Tools - The best manual Newtonian tools.  I use the 2" set with a red (soon to be white triangle)
