TS-Optics GSO 8" f/12 Cassegrain telescope 203/2436 mm OTA Reviews
3/3 Reviews

People should know this, this telescope has an effective diameteter of 186mm not 203mm as advertised by GSO(TS, orion etc). I measured this myself and confirmed it to be true after reading a review which included feedback from Ageenaastro and GSO but I had to measure for myself. This makes the linear obstruction 36% and the F ratio 13. Other than that I look forward to testing this scope as the Optics on my RC8 scopes have been good.
