Askar 50P Telescope The Askar 50P 50 mm f/3.8 Quadruplet Petzval Astrograph is a compact, high‑speed wide‑field imaging telescope perfect for modern astrophotography. Its internal Petzval optical design provides a flat, well‑corrected imaging field optimized for APS‑C and 1″‑type sensors, so you get sharp, detailed images across the frame without the need for additional flatteners. With a fast f/3.8 focal ratio and short 190 mm focal length, the 50P excels at capturing large nebulae, Milky Way fields, and deep‑sky targets with excellent efficiency and portability.
