TPO 2" Mirror Diagonal with SCT Thread - Deluxe Dielectric

The TPO 2 inch dielectric diagonal also features a CNC machined housing. This housing is designed to retain the optimal collimation of the mirror and assure the best optical performance. The CNC machined aluminum housing will provide outstanding results for years of use.

This diagonal also includes brass compression rings on both diagonal and the included 2 inch to 1.25 inch adapter, assuring gentle treatment of your eyepieces. Some other brands use set screw locking mechanisms that can mar the barrel surface of your favorite eyepieces. Avoid scratches and gouges by using the OPT dielectric series diagonals.

TPO dielectric diagonals provide outstanding performance with low prices to provide amateur astronomers with excellent value! TPO backs this diagonal with a full 2 year warranty against manufacturer defects, which may be expanded into a lifetime warranty by purchasing a warranty extension.

This diagonal attaches to the rear cell of SCT's. It is not meant for SC telescopes that have an electric focuser attached to the rear cell. In these instances, we recommend the TPO 2 inch Mirror Diagonal.
