Product Overview
The Askar 50P is a compact, fast astrograph built for wide-field astrophotography. Its 50mm aperture and 190mm focal length deliver a bright f/3.8 system, while the quadruplet Petzval APO design (including SD glass) helps maintain sharp stars and a well-corrected field across common imaging sensors.
