A new apochromatic refractor with high-performance objective lens made of mineral fluorite crystal (CaF2) able to reproduce extremely clear and sharp image by extraordinary eliminating color aberration.

Optical tube is very compact (282 mm length) and light (1.5 Kg) but offers a sturdy focuser able to hold also big and bulky DSLR such as a Canon 5D Mark IV. Dedicated photographic accessories transforms the Vixen FL55SS in a fantastic astrograph corrected up to the full-frame image format (image circle 44 mm) with very high correction and limited vignetting.

Using the dedicated 1.04x Flattener HD the FL55SS transforms into a 55 mm F/5.7 astrograph (312 mm focal length). Adding also the dedicated 0.79x Reducer HD the system turns into a very wide field astrograph with F/4.3 focal ratio (237 mm focal lenght). Vignetting at the edge of the 44 mm corrected image circle is 96% and 86% respectively.
