305MM (12") F/4.9 PARABOLIC DUAL-SPEED NEWTONIAN REFLECTOR
The new Sky-Watcher EXPLORER-300PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-300P but with two significant advantages. A Dual-Speed 10:1 ratio focuser is now included for excellent focusing precision. Also the tube length has been slightly shortened to optimise performance for prime-focus photography.
Even better performance for astro-photography and visual use can be achieved when used in combination with Sky-Watcher’s Newtonian coma corrector (Prod.Code 20233)

44% more Light-Gathering than 250mm
“Compared to our own 250mm f/5 Newtonian reflector, the extra light gathered by the Explorer-300P was obvious. We got impressive views of a wide range of celestial objects. Galaxies such as M65 & M66 in Leo were wonderful, with strong hints of subtle detail along their spiral discs. The nearby galaxy NGC 3628 also stood out well. Nebulae shone against the background sky. M1, the Crab Nebula, showed varying degrees of mottling and scalloped edges – very satisfying indeed. The Orion Nebula, M42-43, was awash with nebulosity and we found we could easily get lost amongst the detail.. At its centre, the Trapezium group of stars sparkled and, at the highest magnifications , we spotted several of its fainter mag. +10 stars, even though the atmosphere wasn’t as steady as we would have liked for such high-magnification views. Detail Explosion: Late into the night we selected the globular cluster M13 from the hand-controller. As it swung into the field of view it was breathtaking, with swarms of stars looking like bees around a honey pot. The view was so good that we noticed a dark feature, commonly known as the Propeller, superimposed on one side of the cluster. It was easily the best view of the cluster we’ve ever had….For crystal clear views of deep space, this is hard to beat!”

SynScan GOTO Mount that will take a massive payload
This is the new NEQ6. Used to be called the EQ6 pro. The differences are twofold:
1) A counterweight extension bar is included in the package – the mount is still supplied with 2 x counterweights though.
2) The mount is now supplied with TWO saddle plates; Sky-Watcher 45mm and 75mm. They are easily interchangeable and can be removed by loosening 3 x Allen screws.
This Monster Mount will satisfy amateur astronomers seeking superior equatorial control and the ease of a precision computerized GOTO system, the EQ6 ProScan is your answer. The Sky-Watcher EQ6 ProScan is designed with the novice user in mind. With the user friendly pushbutton hand control, locating and viewing the treasures of the night sky becomes as easy as a walk in the park. The hand control allows you to point the telescope at a specific object or even tour the skies at the touch of a button. The user friendly menu system allows automatic slewing to over 13,400 objects. Even an inexperienced astronomer can master its variety of features in a few observing sessions. The EQ6 ProScan also comes with features that advanced astronomers can appreciate.
