Stellarvue 2" Quartz Dielectric Star Diagonal with 1.25" Compression Ring Adapter

This is the most advanced version of Stellarvue's most popular diagonal. It was designed by Vic Maris and uses a thick, over-sized mirror polished to 1/10th wave. The mirror has a protective, dielectric coating with 99-percent reflectivity. It has a compression ring eyepiece tube and the insert tube has a bevel that will better seat the diagonal in the focuser. The FA2 deluxe 1.25-inch compression ring adapter is included. Both the two inch insert tube and adapter have filter threads. A rubber grip on the 2-inch tube allows for easy handling in cold climates. These diagonals are assembled, adjusted and double tested at Stellarvue for perfect alignment and performance. The five point cushion system eliminates pinching in all climates and the precision CNC machined components assure perfect alignment that stays that way. The four point adjustment allows us to perfectly align the mirror so every diagonal that leaves here is perfectly aligned. This new version has additional improvements.
