William Optics FLT120 - 120 mm f/6.5 APO Triplet Refractor - Space Gray
The William Optics FluoroStar 120 Refractor is an air-spaced triplet APO. Using three elements made of high-end fully coated glass like FPL-53 virtually removes chromatic aberration and produces images that are sharp and full of contrast. A patented light weight Bahtinov mask is included to provide assistance in focusing, or you can remove it when using the F120 visually.
The FLT120 has a native focal ratio of f/6.5 and a focal length of 780 mm. The big 3.3" rack and pinion dual-speed focuser allows for use of two optional M92 flatteners from William Optics; the FLAT68III, which flattens the field beautifully without focal reduction, or the FLAT7A, an APO flattener and 0.8X reducer. While the FLAT68III is recommended for the best image quality of the two, the FLAT7A reduces the focal ratio from f/6.5 to f/5.2. Both flatteners accept 2" threaded filters.
As with other William Optics refractors, the fit and finish on the FluoroStar 120 is superb. The telescope comes with cradle style mounting, a saddle handle bar, and a universal Losmandy-style dovetail plate. All four pieces are anodized in space gray. The included camera rotator and the Rotolock 2" Adapter are anodized to match. This is one beautiful telescope. By the way, the top of the handle bar has a Vixen-style saddle built in to accept William Optics slide base guide rings for a guide scope or finder. You can also use an accessory mounted on a Vixen dovetail.
