Description
TS SCT Star Diagonal Mirror - 99% Reflectivity
--- QUARTZ mirror substrate ---

A high grade star diagonal mirror with a very precise mirror surface (approx. 1/12 lambda) for demanding users.

99% reflectivity means more light and thus a brighter image. At the same time the dielectric coating is very strong and protects the mirror surface.

2" Star Diagonals offer a larger possible field of view compared with 1.25" diagonals. This is particularly important for deep sky observing through Schmidt-Cassegrains and Maksutovs with their rather long focal length.

The diagonal screws directly onto the SCT thread at the rear of the telescope. Most Schmidt-Cassegrains and many Maksutovs have this thread.

The diagonal accepts both 1.25" and 2" accessories.

Compatible Telescopes: Celestron / Meade SCTs - Intes / Intes Micro Maksutov Cassegrains ........... and similar


Quality Features:

-- all metal design
-- SC thread adpatation
-- 2" accessories are held in place with a brass compression ring
-- 1.25" adapter also with compression ring
- very good optical quality (1/12 lambda surface)
-- 99% reflectivity
-- dielectric coating
-- Quartz mirror substrate



Brass Compression Rings ( 2" and 1.25" )

1.25" and 2" accessories are securely held in place using a compression ring.

The advantages of compression rings compared with regular locking screws are:

-- the compression ring avoids signs of use. Accessories are not scratched.

-- safer grip and a reduced tendency that accessories are tilted out of the optical axis.


Quartz Mirror

Quartz is a particularly excellent mirror substrate for high precision diagonal mirrors.

Quartz mirrors have better thermic properties and almost no thermic expansion..

Specifications:

-- 2" SCT star diagonal - CNC machined metal body
-- telescope adaptation: SC thread (UNC 2"-24)
-- 2" clamp with compression ring. 1.25" adaptor also with compression ring
