TPO 2" SCT Quartz Dielectric Diagonal
TPO's quartz dielectric diagonal provides greater thermal stability than comparable glass diagonals, resulting in minimal thermal expansion and contraction. This quartz diagonal, therefore, minimizes focus position change due to variations in temperature.
The TPO 2” quartz dielectric diagonal also features a CNC machined housing. The CNC machined aluminum housing will provide outstanding results for years of use. This housing is designed to retain the optimal collimation of the mirror and assure the best optical performance.
This diagonal also includes brass compression rings on both diagonal and the included 2” to 1.25” 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 quartz dielectric diagonals provide outstanding performance with low prices to provide amateur astronomers with excellent value! OPT backs this diagonal with a full 2 year warranty against manufacturer defects.
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 OPT 2" Quartz Dielectric Diagonal.
