Converts the FL55SS into a high-performance astrograph The kit consists of a high-performance flattener lens, a reducer and the EX TUBE 66 connection ring, which was developed for the FL55SS Fluorite Apochromatic Refractor and improves photographic performance by dramatically flattening the surface.
Ultra-sharp image over the entire field of view of the DSLR full-frame sensor
The Flattener HD for the FL55SS reduces the change in the focal length of the FL55SS to a minimum and improves the evenness of the surface for prime-focus photography. 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 image circle retains a diameter of 44 mm, which significantly improves the sharpness across the entire field of view of DSLR cameras with a full-frame sensor.
96% light volume to the edge of the field of view
The Flattener HD was specially developed for the FL55SS refractor to reduce loss of light to a minimum across the entire 44 mm image circle of full-frame DSLR cameras.
Exceptionally high contrast
The same anti-reflective AS coatings used on our high-end VSD 100 f/3.8 astrograph are used to provide an outstanding light transmission of 99.9% per lens surface. Thanks to the matte black surface of the Reducer HD kit, loss of light, ghosting and scattered light and largely prevented.
