With its unique VISAC (Vixen Sixth-Order Aspheric Cassegrain) primary mirror, the optical system is composed of a concave primary mirror, a convex secondary mirror and a three-element field corrector. Especially noteworthy is its sharpness and flatness at the edge, which far exceeds that of Schmidt- Cassegrain systems of the same aperture. It provides a pinpoint star image of less than 15 microns, even at the edge of its 42mm image circle. The open tube design eliminates the dew problem that is

They can be used in place of a Barlow lens for imaging applications. Extends the focal length of the R150S from 750mm to 1500mm (f/10) and the R130S from 720mm to 1440mm (f/11). Model # AV-TE-3631 Focal Reducer R130S/R150S Focal reducers shorten the effective focal length of telescopes to provide wider visual fields and faster f-ratios for astrophotography. This focal reducers is for astrophotography only. Shortens the focal length of the R150S from 750mm to 652mm (f/4.3) and the R130S from 7
