Product Details

  • The 10-inch F/8 Ritchey Chretien Truss Tube OTA from TPO is an all-around 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 scope's 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 10 inch F/8 RC then, is a superlative astrograph capable of almost any imaging task. One of the most notable features is indeed its extreme versatility and adaptability. 

    This Third Planet Optics (TPO) Ritchey Chretien telescope has 10 inches (254mm) of aperture and a focal length of 2032mm. 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.
