Askar PHQ Astrographs

Askar PHQ astrographs are flat-field apochromatic refractors built around four-element designs, made to deliver a flat field across the sensor for imaging. The f/7 range covers the 80PHQ, 107PHQ, 130PHQ and 151PHQ quadruplets, and the compact 65PHQ is an f/6.4 quintuplet.

Matched reducers shorten each setup: 0.75x for the 65PHQ, 0.76x for the 80PHQ and a 0.7x universal reducer shared by the 107PHQ, 130PHQ and 151PHQ. The larger models suit galaxies and small nebulae at longer focal lengths.
