Astromania 2" 90-Degree Mirror Diagonal with 93% reflectivity across visible spectrum

About 2" 90-Degree Mirror Diagonal with 93% Reflectivity Across Visible Spectrum

90 Degrees Observation Angle
View the object at 90 degree from the direction the telescope is pointing. This makes observations quite comfortable when the telescope is at or near the zeni-th.

What Product To Use With
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 advantages in a nutshell：

•  2'' diagonal
•  Dielectric coatings
•  High optical lens transparency
•  93% reflectivity and 1/10 wave mirror
•  The all diagonal body is metal
93% reflectivity&a 1/10 wave mirror&Dielectric coatings

2'' Diagonal
Allows you to take advantage of the wider field of view provided by two inch eyepieces.

The All Metal Diagonal Body
The all metal diagonal body is CNC machined.It makes the structure more durable.

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

Thread for Eliminate Light
Effectively reduce stray light interference, not only improve the brightness of the image, but also effectively reduce the dark edges formed, the edge details of the image are clearer.
