2" Dielectric Refractor Diagonal

Looked at the reviews and such and couldn't find much on diagonals. I'm looking to buy a 2" Dielectric Refractor Diagonal. I've narrowed my choice to either Williams Optic or Stellarvue.

Please tell me the pros, cons, quality, etc. of these two choices. I looked at the AP and TV offerings and couldn't see any reason to go the extra $100. Couldn't understand why AP doesn't come with 1 1/4" adapter and you have to measure the depth so you don't hit the mirror? TV looks nice but the build looks similar to the Stellarvue.

So you folks decide for me please. Joe C

Joe, they are both great, you can't go wrong with either one... just make up you mind and get one! 8)

Joe,

there are differences in the size, thickness of the mirror and in SV final checkup for collimation. I know that SV put a long effort in the design. The WO might look more "slick" but I would go with SV.

Thanks to all that responded. As usual you can count on this site.

One comment you see when folks talk about 1/10th wave mirrors, if they truly are, is no discernable difference when swapping.

So in the long run it comes down to the mechanics, alignment and quality of the build.

The AP diagonal looks like it has some very interesting baffling and high quality flocking.

So thanks again and I'll be picking up the Stellarvue next weekend. Going to the toy store, yippie.
