The optics: The Sky-Watcher Explorer-150PL Newtonian telescope is an excellent choice for the aspiring astronomer as well as for the interested beginner. It features a large 150mm aperture combined with the superb parabolic optics. With its larger focal length (f/8) it enables a higher magnification than the f/5 version (Explorer-150P) with the same eyepiece focal length. It delivers excellent performance when observing the moon, planets, nebulae, galaxies, star clusters and close double stars. Mount: Sky-Watcher offers a simple solution for hobby astronomers who want to place their small telescope on a convenient computer-controlled mount, but do not want to use a heavy HEQ5 or EQ6 mount. The EQ3 Pro SynScan™ mount uses the same GoTo system used in the HEQ5 and EQ6 Pro SynScan™ mount. It allows the user to set any object or start a guided tour of the night sky with just a push of a button. The extensive database contains over 42,900 objects in the night sky. The Sky-Watcher EQ3 Pro SynScan™ mount is the perfect instrument for beginners in visual observation or photography to enjoy the new hobby with minimal setup effort and without already knowing the sky perfectly. The mount comes with an aluminum tripod. Please note: The motor control box (seen to the left of the hand control box in the picture) is designed to be attached to a tripod with 1.75″ stainless steel legs. However, you can attach them with Velcro or similar.
