Askar SQA85 f/4.8 85/408 is a professional astrograph dedicated to work with full-frame cameras and cameras.
The optical system of this astrograph consists of five lenses, two of which are made of super low dispersion (SD) glass. This design not only provides excellent resolution and image detail, but also excellent color reproduction thanks to effective correction of chromatic aberrations. The applied optical design allows work in a wide range of working distance, which, combined with a double system of coarse and fine focusing, significantly facilitates the operation of the lens.
The very good optical properties are accompanied by the quality of workmanship. Both the body and the sunshade are made of metal. Thanks to this, the construction of this telescope is not only solid, but also allows for secure and stable attachment to a tripod or mount using the included foot. • apochromatic astrophotography lens with excellent field curvature correction
