Assembled and tested atáStellarvue's Auburn California facility, the new SV115T provides exceptional performance. Zero false color and perfect star test, the SV115T was a 2 1/2 year project that continues in Stellarvue's tradition of excellence. Like all Stellarvue telescopes, each one is Zygo and star tested by Vic Maris. This telescope may be used visually, photographically and withá binoviewers. Most refractors require binoviewer adapters which reduce field size but the SV115T refractor may be used without an adapter allowing for the widest possible field when used with binoviewers. All other models may be used with binoviewers but like most refractors, they require a refractor adapter.
