Vixen Reducer HD Kit for FL55SS Telescopes

Vixen Telescope Focal Reducer HD We are introducing this high-quality and functional Focal Reducer HD by Vixen Optics. It will deliver high performance in Astrophotography. There's a development of the FL55SS fluorite refractor to a high-performance astrograph; The kit composes the reducer, the extension tube "EX TUBE 66", and the flutter for flattening the image field, which was developed for the FL55SS Fluorite Apo refractor. You'll get a sharp image right up to the DSLR camera in the fully pre-mat sensor at the edge. This Flattener HD for FL55SS levels is the full view of the full-frame DSLR camera in primary photography. It gives Ultra-sharp images across the entire field of view of the DSLR full-frame sensor. The image circle 44mm captures the DSLR camera's entire full-frame field of view. The focal length is deducted 0.79 times (from F5.5 to F4.3), combo with the Reducer HD5.5. The illumination of 44 mm is retained, ensuring prime focus over the DSLR camera's entire image field.
