The new Japanese-made Vixen VSD100 f3.8 telescope features an innovative 5-element lens design with an SD lens in the front objective group and an ED lens in the rear group for a large, flat, evenly illuminated field with superb colour correction! The blue halos around stars that are perceptible in simpler designs are completely absent. In addition, astigmatism and coma aberrations are corrected to a very high level. 

The lenses of the VSD100F3.8 have modern lens multi-coatings developed to match the characteristics of each lens element to achieve 99.9% light transmission at the maximum per lens surface and high contrast without ghosting or flare (patent pending). 

The Strehl intensity of the VSD100F3.8 optics is approximately 10% better than most 4 element lens designs. 

The image circle is as large as 70mm in diameter (60% illuminated) and the star images are as small as 15 microns around the corners, resulting in excellent field flatness. 

The Vixen VSD 100 f3.8 also features a large helical focuser with fine focus scale for smooth, precise, repeatable focusing. 

Optional Focal Reducer and Tele-Extender

A 3-element focal reducer (0.79x) and a 4-element tele-extender (1.58x) will also be available soon. When used with these accessories, the VSD100F3.8 can be transformed to an even faster 300mm f3 astrograph or a versatile 600mm f6 telescope for both imaging and visual astronomy!
