Size:2" 90-degree Diagonal 93% with SCT Adapter Astromania's 2" SCT mirror
diagonal is an excellent alternative to higher priced diagonals for those on a
budget or just getting started in the 2" format. The 2" SCT diagonal features
dielectric coatings with 93% reflectivity across the visible spectrum and a
1/10 wave mirror. The all metal diagonal body is CNC machined. The combined
result is a superb diagonal offering excellent mechanical and optical quality
at a great price. You can attach this diagonal directly to Schmidt-Cassegrain
telescopes and many Maksutov-Cassegrain telescopes, as long as there is a SCT
male thread on the telescope. The standard SCT thread is a 2"x24tpi
thread.Star diagonal is the term commonly associated with 90°mirror diagonals
such as this, which let you view objects that are at a 90°angle from the
direction the telescope is pointing. This allows quite comfortable viewing
when the telescope is at or near the zenith. Upgrading your diagonal and
switching to 2" eyepieces is one of the best investments you can make in your
telescope. The wider diagonal captures more of the telescope's light cone,
perfect for viewing faint, deep sky objects like nebulae and galaxies.
