BAADER 1.25" T2 PRISM DIAGONAL 32mm is backordered and will ship as soon as it is back in stock.
The Baader 1.25" T2 Prism Diagonal is a high quality prism diagonal for observation with 1.25" eyepieces and is ideal for the Baader MaxBright Binoviewer.
Unlike most low-cost erecting prisms which only have 19mm of free aperture, the Baader 1.25" prism has a much larger 32mm of free aperture. The prism has Baader's High Transmission Multi-Coatings for high contrast and stray light suppression.
Both telescope- and eyepiece-side barrels can be unscrewed to reveal T2 (M42 x 0.75) threads for applications where backfocus is limited such as binoviewers. The 32mm free aperture makes it especially suited for use with the MaxBright II with 27mm prisms. For larger apertures such as the Mark V giant binoviewer, the T2 BBHS Prism Diagonal BA2456095 is recommended.
