Williams Optical 105/650
A superb performer. Pinpoint star images with no coloration or fringing. A little heavy for my GM8 but perfect sharing my AP900 with the Tec 6. I use Pentax 40mm and an assortment of Radian/Brandon ep's and have seen no shortcomings. I use this with a Takahashi finder. The only complaint I have is that the finder must be placed on the left side of the tube and I have a damaged right eye and causes some consternation. I can rotate the ota to accomodate its use though.

An excellent scope. Star tested with between 1/4 and 1/8 th wave spherical aberration. Focuser not as smooth as a Tak or Vixen. Looks great and a stunning performer. Images bright for the aperture.
Planetary images excellent even despite the imperfect star test.
