Astromania 2' 90-Degree Mirror Diagonal with 93% reflectivity Across Visible Spectrum

Product Description

It fits all rear cells of Schmidt-Cassegrain telescopes equipped with a big, 2" focuser and can use with refractor telescopes with SCT adapter which you can find in our store(NOT INCLUDE).

The 2" diagonal features dielectric coatings with 93% reflectivity across the visible spectrum and a 1/10 wave mirror for bright and true images.

Allows you to take advantage of the wider field of view provided by two inch eyepieces. Dielectric coatings are more durable than regular or enhanced aluminum coatings, so you will enjoy years of excellent performance from this product.

Associated with 90°mirror diagonals, which let you view objects that are at a 90°angle from the direction the telescope is pointing.

Improved attachment design features a brass clamping ring which does not mar, and provides a more secure connection.
