The TPO 2" Mirror Deluxe Dieletric Diagonal with SCT Thread features 99% reflectivity, dielectric coatings to maximize light output of your telescope system. Our custom made diagonal uses a BK7 mirror polished to 10th wave accuracy or better for best possible image quality. It also features a CNC machined housing that is designed to retain the optimal collimation of the mirror and assures 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 TPo 2" Mirror Deluxe Dieletric Diagonals.
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" Deluxe Dieletric Mirror Diagonal.
