The optics: The new Sky-Watcher Explorer-150PDS Newtonian Reflector telescope includes the same excellent optics as the Explorer-150P Black Diamond series, but with two key improvements. A 10:1 gear reduction focuser was used for greater focusing precision, and the tube was slightly shortened to improve performance in primary focus photography. Even better performance can be achieved when using the Sky-Watcher Newtonian coma corrector (No. 20233) for both visual observation and photography. The mount: The high-quality Sky-Watcher EQ3-2 mount gets high praise from experienced observers. This sturdy mount offers high precision and stability along with the ability to expand further for the experienced astronomer. The mount sits on a large, adjustable aluminum tripod with a shelf. A spirit level allows the mount to be leveled quickly and accurately. Fine movement knobs allow continuous manual tracking of celestial objects. The mount includes 360° tracking gears in both axes (RA and DEC). Metal graduated circles allow objects to be set quickly using celestial coordinates. A polar finder scope is available as an option for more accurate polar alignment. The mount can optionally be retrofitted with motorized tracking in right ascension or in both axes or with a SynScan GoTo control.
