Sky-Watcher Explorer-250PDS Parabolic Dual-Speed Newtonian Reflector OTASky-watcher Explorer-250pds Parabolic Dual-speed Newtonian Reflector Ota
Sky-Watcher Explorer-250PDS 254mm (10") f/1200 Parabolic Dual-Speed Newtonian Reflector Optical Tube Assembly. The new Sky-Watcher EXPLORER-250PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-250P 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 (Product Code 20233). Please note this is an Optical Tube Assembly only, mount and tripod are available separately.

Sky-Watcher Explorer-200P (EQ5 PRO) Parabolic SynScan GO-TO Newtonian Reflector TelescopeSky-watcher Explorer-200p (eq5 Pro) Parabolic Synscan Go-to Newtonian Reflector Telescope
Sky-Watcher Explorer-200P (EQ5 PRO) 200mm (8") f/1000 Parabolic SynScan GO-TO Newtonian Reflector Telescope. All Sky Watcher Black Diamond Newtonian Reflectors feature 0.5mm ultra-thin secondary mirror supports to reduce diffraction spikes and light loss, and high quality Paraboloidal primary mirrors to eliminate spherical aberration. The mirrors are ‘parabolised’ to bring all the light rays to the same focal point to produce sharp, contrasty images which are full of detail. Ideal for Planetary and deep sky observation.
