Description

Details

The 10" F/8 Ritchey-Chretien Truss Tube OTA from TPO is an all round excellent scope that boasts incredible versatility, maximizing every inch of it's 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 10" F/8 RC then, is a superlative astrograph capable of almost any imaging task. One of it's most notable features is indeed it's 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 10" (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.

Great
This is an awesome telescope for astrophotographs. It seems to have the correct balance between focal lenght and aperture for CCDs.
I use and recommend TPO reducer 0.8x. The set has round stars from side to side in a 8300 CCD.
Ive never used the fans and focus hold all night.
An incredible scope for the price.

Great scope for the price
This scope is beautiful, great fit and finish. Scope maintains collimation and is very easy to setup with provided spacers and mammoth focuser. Really a great value for the price. You get a dust cover for the secondary, but no cover for the primary. You also do not get any documentation. It would be nice to get both.
