The optics: The new Sky-Watcher Explorer-250PDS Newtonian Reflector telescope includes the same excellent optics as the Explorer-250P Black Diamond series, but with two key improvements. A 10:1 gear reduction focuser was used for greater focusing precision, and the tube was shortened slightly 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: For amateur astronomers looking for a high quality equatorial mount with the convenience of a computer controlled GoTo system, the NEQ6 Pro SynScan™ is the right choice. The Sky-Watcher NEQ6 Pro SynScan™ was also developed with the beginner in astronomy in mind. With the user-friendly push-button hand control, finding and observing objects in the sky becomes as easy as a walk in the park. The hand control allows the telescope to be aimed at the desired object or simply to start a guided tour of the night sky with the push of just one button. The user-friendly menu contains a database with over 42,000 objects of the night sky. Even an inexperienced beginner can learn the various functions of the system in just a few observation nights. However, the Sky-Watcher NEQ6 SynScan™ mount also contains many functions for the experienced amateur astronomer.
