Gso 10 classical cassegrain will it be a worthy upgrade over 6 inch RC, that I currently have? I have seen planetary imaging limits on 6 inch RC, but it is ok for DSO. Rediscover the elegance of classical design with the GSO 10" F/12 M-LRC Classical Cassegrain Truss Carbon OTA. 8" f/12 Classical Cassegrain Telescope by GSO Classical Cassegrain telescope with 8” aperture and focal ratio of f/12, ideal for visual observation and imaging of the Moon, planets, double stars, planetary nebulae, and other compact celestial objects Folded optical design packs a focal length of 2436mm into an optical tube only 535mm long GSO 8" f/12 Classical Cassegrain Reflector Telescope OTA (Black) 13 Reviews $1,149. 5" f/12 Classical Cassegrain – A Quick First Peek - posted in Cats & Casses: A C9. My brother has a 4” Unitron (model 166), a classic 6 F15 brass Carroll refractor, plus an excellent 1990s vintage, USA-made C9. I was planning on a multi scope ‘shootout’ as I discussed yesterday with several of my 4” refractor herd but I see no reason not to include the Vixen in the TS-Optics GSO 6" f/12 Classical Cassegrain Telescope Cassegrain telescopes combine the benefits of a Newtonian telescope being a pure reflective system with a short-built design. With a focal length of 3048mm, it offers excellent lunar and planetary imaging and razor-sharp visual observation. Classical Cassegrains have a hyperbolic secondary and a parabolic primary, making them very sensitive to collimation errors much like a RC.
