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 -- 99% reflectivity, 1/12 lambda surface quality -- dielectric coating -- Quartz mirror substrate |
Scope of Delivery: -- 2" SCT diagonal mirror. 2" clamp with compression ring |
