Vixen Reducer HD Kit for FL55SS Telescopes
Convert your FL55SS fluorite refractor into a high-performance astrograph
The kit includes a high-performance reducer, flattener and the "EX TUBE 66" extension rube, which was developed for the FL55SS Fluorite Apo Refractor and improves the photographic performance by flattening the image right up to the edges.
Ultra-sharp image over the entire field of view of the DSLR full-frame sensor
Designed for prime-focus photography with the FL55SS, the Flattener HD flattens the entire field of view of full-frame DSLR cameras.
The 44 mm image circle covers the entire field of view of a full-frame DSLR camera.
When used in combination with the HD5.5 Reducer, the focal length is reduced by 0.79x (from f5.5 to f4.3) and the illuminated area retains a diameter of 44 mm, which significantly improves the sharpness across the entire field of view of the DSLR camera.
96% illumination to the edges of the field of view
The Flattener HD was specially developed for the FL55SS refractor in order to reduce light loss to a minimum.
The field of view is fully illuminated up to the edges.
Exceptionally high contrast
The same anti-reflective AS coatings used on our high-end VSD 100 f/3.8 astrograph are also used here to provide an outstanding light transmission of 99.9% per lens surface.
In addition, the matte black surface of the Reducer HD kit eliminates loss of light, ghosting and scattered light.
