Williams Optical Diagonal.

Hi All,
I was thinking of buying a new diagonal to replace the stock Meade that
came with my LX90. WO has 2 of them I am thinking of. The first is the 2"
90 degree Star Mirror for $99. The second is the "New Generation" 2" 90
degree for Schmidt-Cassegrains or Maks for $130. I am wondering what the
difference is between these 2. Which one would work best with the LX90?
Thanks. - Dave

First of all, I don't know what the difference between the two is exactly.
When I was shopping for a 2" diag for my LX90, I thought WO had a SCT type & a
regular 2" type. I have the $130 model. I switched since the stock 1-1/4"
diag stunk. The generic 2" SCT diag I picked up originally didn't clear the
base of the LX90. The WO 2"SCT diag is nice & worth the money. That's it in a
nutshell.

The SCT version threads onto the rear cell.
THe plain 2 in version will need an ST rear adapter that takes 2 in
accessories; but the diagonal will be usable on other 2 in accessorie
scopes as well.

Kendrick Astro Instruments has the refractor version...

....and in stock, but going fast no doubt as Anacortes has at least 30 backorders
for the exact same version.

Kendrick might also carry the Schmidt-Cassegrain version.

Hi,

The WO Diagonal for SCT is not a true 2-inch diagonal (nothing that threads
onto the SCT adapter is). There are arguments on both sides of this issue
but for a true 2-inch aperture the way to go is with the "$99 star mirror"
with an Astro-Physics 2-inch adpater. Cost is the same as with the SCT
diagonal and you get a true 2-inch aperture.

Take Care,

JAS
