About this product
Part Number: X000154
This kit consists of a high performance flattener lens, a high performance focal reducer and a connecting tube ring. It improves image quality of photography by achieving a flat focal plane and reduces the focal length of the FL55SS by 0.79 times. The flattener lens corrects aberration on the periphery of a photographic field of view and it keeps images of stars sharp throughout the photographic field. The focal reducer achieves faster photographic speed of F4.3 by reducing the scope's focal length.
