The brand-new 80PHQ refractive astrograph. And it's the second long-focal-ratio astrograph from the PHQ-family. The overall finish of 80PHQ is evenly painted. The ivory and flawless coating of the main tube feels comfortably pimply,which can not only increase your grip, preventing the telescope from slipping off from your sweaty hands, but also improve its texture, avoiding the tedious monotony.
