Sky-Watcher Explorer 200PDS OTA
The new Sky-Watcher EXPLORER-200PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-200P Black Diamond Series, 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)

The standard f/5 version of the evergreen 200P but with a dual speed Crayford focuser. Not as wide a field for imaging as the f/4 Quattro, but on the other hand, not as much coma off axis.
Budget for a good quality coma corrector – essential. Preferably, one that does not alter the focal length of the telescope. Construct a matt black dew shield of some 300mm in length. This will help to draw cool air up through the telescope passively, and also decrease light reflections around the secondary position.
