• The 12 inch F/8 Ritchey Chretien Truss Tube OTA from TPO is an all round excellent scope that boasts incredible versatility, maximizing every inch of its aperture. The fixed position quartz primary mirror utterly negates image shift, and also removes the otherwise frustrating task of collimating a scopes primary mirror. Furthermore the carbon fiber truss tube design drastically reduces the threat of possible temperature shifts causing flexure, the design lending itself to minimizing thermal shifts. The Ritchey Chretien design has virtually no coma, chromatic aberration, or spherical aberration, and is an all around improvement to the Cassegrain while attaining many of the same objectives. The TPO 12 inch F/8 RC then, is a superlative astrograph capable of almost any imaging task. One of it's most notable features is indeed its extreme versatility and adaptability. The only astro-imaging task that it is not exceptionally well suited to is wide field, as it does have a notably narrow field of view. This Third Planet Optics (TPO) Ritchey Chretien telescope has 12 inches of aperture and a focal length of 2432mm . The concave hyperbolic primary and convex hyperbolic secondary are made from low expansion quartz, and finished with a scratch-resistant highly reflective 99% dielectric coating for great contrast. The primary mirror is fixed in place in a metal mirror cell, and the secondary resides in a metal housing that can be collimated.
