This Baader T-2 90-degree Maxbright dielectric mirror diagonal consists of a diagonal body with mirror ONLY and includes no nosepiece or eyepiece holder. It has standard T/T-2 threads at the input face (with female T/T-2 thread on the telescope side) and at the output face (with male T thread on the eyepiece side). This lets you add Baader Planetarium T-2 adapters and accessories to configure the diagonal to your needs.
One of the key features of this Baader T-2 diagonal – and all Baader diagonals, whether they use prisms or mirrors - is the large free aperture and the flexibility to directly adapt to almost any telescope system, without the restriction of a 1.25" barrel size which may cause vignetting in long focal length 1.25" eyepieces or when using the diagonal with a binoviewer. That is precisely why Baader offers the body of all their T-2 System diagonals without adapters. The clear aperture of this diagonal body is 33mm.
It incorporates the finest and most precisely-engineered star diagonals on the market today. This mid-sized and highly flexible Baader T-2 90° diagonal body with Broadband Hard-Coated Silver (BBHS) mirror is ideal for high-power planetary viewing and general deep-sky observation. The diagonal works well for systems where back-focus or space is limited and a full aperture 2" diagonal will not work or is not flexible enough.
The BBHS mirror diagonal ideal diagonal for use with any telescope including fast refractors that may suffer from the slight spherochromatism caused by prism-based diagonals. The tradeoff is slightly longer optical path length. The effective optical path length of this base T-2 diagonal with Maxbright dielectric mirror is 43mm.
Note: This diagonal gives images that are upright but left-right reversed.
