Celestron 2-Inch Mirror Diagonal With XLt Coatings, Black

The Celestron 2 inch Mirror Diagonal was built for superior performance. The housing is machined with precision instruments to make sure the optics stay perfectly aligned. The mirror’s surface is covered with the same high performance XLT coatings used on Celestron’s best telescopes and the result is a sharp, bright image that will satisfy the most discriminating amateur astronomer. This 2 inch diagonal threads securely to the rear cell of standard Schmidt-Cassegrain telescopes. To take advantage of the XLT Diagonal’s extra light throughput, insert a 2 inch eyepiece into the barrel. If you want to use 1. 25 inch eyepieces, slide the included 2 inch to 1. 25 inch adapter into the eyepiece barrel and secure it with the thumbscrew. When you’re not observing, store your diagonal in the included aluminum case for protection. 1 x Diagonal Mirror with XLT Coating 2 inches.
