TS Optics Diagonal mirror 90° SC/2" (75507)

The TS Optics Diagonal Mirror 90° SC/2" is a premium accessory designed for astronomers who want the brightest and sharpest images from their Schmidt-Cassegrain or Maksutov telescopes. With a highly precise mirror surface (about 1/12 lambda) and a durable dielectric coating that achieves 99% reflectivity, this star diagonal maximizes light transmission and ensures long-lasting performance. The 2" format allows for a much wider field of view compared to 1.25" diagonals, which is especially valuable for deep-sky observations with telescopes that have longer focal lengths. The diagonal attaches directly to the SC thread at the back of the telescope, providing a secure and stable fit.

This diagonal mirror is an excellent choice for those seeking superior image quality, a wide field of view, and robust construction for their SC or Maksutov telescope setup.
