2" Mirror Diagonal with XLT Coatings
- 2" SCT mirror diagonal with high performance XLT coatings
- 1/10th wave mirror is tested with an interferometer to ensure quality
- Housing is precision machined to achieve and hold good optical alignment
- Includes a 2" to 1.25" adapter and aluminum carry case
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 2â€ diagonal is required if you want to use 2â€ eyepieces when observing with your telescope. The larger 2â€ barrel allows you to see a bigger percentage of the telescopeâ€™s light cone, which works wonders for capturing faint deep sky objects with low surface brightness.
The Celestron 2â€ Mirror Diagonal was built for superior performance. The housing is machined with precision instruments to make sure the optics stay perfectly aligned. The diagonalâ€™s mirror is tested with an interferometer, and is guaranteed to be 1/10 wave or better. The mirrorâ€™s surface is covered with the same high performance XLT coatings used on Celestronâ€™s best telescopes, and the result is a sharp, bright image that will satisfy the most discriminating amateur astronomer.
This 2â€ diagonal threads securely to the rear cell of standard Schmidt-Cassegrain telescopes. To take advantage of the XLT Diagonalâ€™s extra light throughput, insert a 2â€ eyepiece into the barrel. If you want to use 1.25â€ eyepieces, slide the included 2â€ to 1.25â€ adapter into the eyepiece barrel and secure it with the thumbscrew. When youâ€™re not observing, store your diagonal in the included aluminum case for protection.
