The SVBONY 0.8x SV193 2" reducer and flattener is a dedicated accessory for the SVBONY SV503 ED 80 mm telescope. It guarantees excellent field correction and shortening of the focal length, which is very desirable in astrophotography, allowing you to expand the field of view of the optical instrument.

This reducer reduces the focal length by a factor of 0.8x, which in the case of the SVBONY SV503 ED 80 mm astrograph gives a value of 448 mm at f/5.6. Such parameters allow not only to take breathtaking photos in a wide field of view, but above all significantly shorten the exposure time. To ensure the highest image quality with high contrast and detail, all lenses of the reducer are covered with a full multilayer coating (FMC).

The optical system of the reducer is enclosed in a durable housing made of aluminum protected by hard anodizing.
