This is our most popular diagonal. It was designed by Vic Maris and uses a thick, oversized mirror polished to 1/10th wave. The mirror has a protective, dielectric coating with 99% 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" compression ring adapter is included. Both the two inch insert tube and adapter have filter threads. A rubber grip on the 2" 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.
Star diagonals are a critical component of any refractor. The performance of an otherwise excellent telescope can be seriously compromised using a diagonal that is misaligned or pinched. We researched diagonal design and fabrication for two years before introducing our first 2” dielectric diagonal.
Each diagonal and erecting prism we sell is tested for alignment and will preserve the exceptional quality of your Stellarvue telescope.
