Baader Planetarium's 2" 90-deg prism diagonal features a premium quality Zeiss prism housed in a precision CNC machined Baader diagonal body. The Zeiss prism has acclaimed T-coatings for obtaining the highest image definition.
The 2" eyepiece holder features a brass compression ring and dual locking thumbscrews. 2" nosepiece is threaded to accept standard 2" astronomy filters (M48x0.75). Diagonal weight = 22.9oz.
On the eyepiece side, the 2" eyepiece holder can be unscrewed. This will expose an inverter ring with an SCT male thread (2" x 24TPI). Removal of this inverter ring then exposes an SCT female thread on the diagonal body. On the telescope side, the nosepiece can also be unscrewed, exposing SCT female threads on the housing. Hence, this diagonal can be closely coupled with an SCT telescope (using the optional SCT lockring) to provide the shortest physical connection for fork-mounted telescopes with limited base clearance. It can also be used with a variety of other Baader T-2 system components (sold separately) for various adaptations.
