Askar 151 PHQ Review - Part 2: Optical Test

This is the second video of a two-part series in which I review Askar&latest astrograph, the awesome Askar 151 PHQ, a monster 6" refractor with a 1,050mm focal length. In the previous video, I did an unboxing and shared my first impressions. In this video, I go over the results of a series of quantitative and qualitative optical tests I ran on this telescope and its reducer.
