Home Accessories Diagonals Telescope Diagonals For Astronomy Celestron XLT Mirror Diagonal SCT 2 Inch
There are few telescope accessories that work as hard or matter as much as a diagonal! An integral part of the optical chain, a good diagonal can make a big difference in the quality of the image you see. A 2" diagonal is required if you want to use 2 eyepieces when observing with your telescope. The larger 2" barrel allows you to see a bigger percentage of the telescopes light cone, which works wonders for capturing faint deep sky objects with low surface brightness.The Celestron 2"Mirror Diagonal was built for superior performance. The housing is machined with precision instruments to make sure the optics stay perfectly aligned. The diagonals mirror is tested with an interferometer, and is guaranteed to be 1/10 wave or better. The mirrors surface is covered with the same high performance XLT coatings used on Celestrons best telescopes, and the result is a sharp, bright image that will satisfy the most discriminating amateur astronomer.
This 2" diagonal threads securely to the rear cell of standard Schmidt-Cassegrain telescopes. To take advantage of the XLT Diagonals extra light throughput, insert a 2 eyepiece into the barrel. If you want to use 1.25" eyepieces, slide the included 2" to 1.25" adapter into the eyepiece barrel and secure it with the thumbscrew. When youre not observing, store your diagonal in the included aluminum case for protection. This premium diagonal is designed to work with Schmidt-Cassegrain telescopes such as all those from the Celestron range and is compatible with Meade LX90 and LX200 telescopes or any instrument with an SCT rear cell.2" Diagonal (for SCT)Celestron's high performance XLT coating for maximum reflectivity Interferometer tested 10th wave flat mirrorAll machined housings for accurate optical alignmentAluminum case for storage and protection
Celestron XLT Mirror Diagonal SCT 2 Inch I am the proud owner of a Ceslestron C6S Advanced Series GT SCT. The basic star diagonal is unsatisfactory for this SCT. The 2" XLT diagonal exhibits mega quality and performance. Accepts 2" and 1.25" eyepieces (using the adapter). No twist locks but you have thumb screws. Very Highly Recommended.
