TS-Optics 8" Ritchey-Chrétien Pro RC Telescope 203/1624 mm OTA$1,219.95
This is due to the use of two mirrors - a hyperbolic primary mirror and a convex hyperbolic secondary mirror. The image is coma-free and has a wide field of view. The open system and quartz mirror mean that RC OTAs cool quickly and there is virtually no problem with dew.
