Celestron 2-Inch XLT Diagonal Mirror (for SCT Telescope)
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 telescope’s 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 diagonal’s mirror is tested with an interferometer.
