In contrast to zenith mirrors, the optical path is closed to the rear on this prism. This prevents contamination of the internal optics. In addition, a possible degeneration of a mirror surface is excluded, the transmission values (reflection) remain constant.

The prism diagonal (glass substrate K9 = BK-7) is precisely manufactured and offers the highest resolution. Contrast and image brightness are effectively supported by the UBMC ultra broadband coating.

The stable body is precisely CNC-milled. The accessories are held securely with the modern 2" APM quick-release clamp (Q-Lock). The eyepiece-side accessories are held in place over the entire surface by means of a ring clamp. In contrast to clamping screws, the eyepiece or adapter is centered and precisely on the optical axis. Not pressed against the opposite surface. The front 2" barrel can be unscrewed and has the familiar 2" SC thread.
