Product Name: Explorer-200pds (HEQ5 PRO) , Telescope Model NO.: EXPLORER-200PDS (HEQ5 PRO) Aperture: 200mm Focusing Type: External Focus Objective Aperture: 200mm Lens: Glass Lens Type: Aspheric Surface Usage: Astronomical Function: Outdoor Use Magnification: 50X-100X Type: Astronomical Telescope Trademark: Sky-Watcher Transport Package: Carton Specification: D200/F1000 Origin: China Product Description 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)*Note: the Explorer-200PDS has a larger 58mm secondary mirror, for enhanced field illumination, compared to the Explorer-200P which has a 52mm secondary.STANDARD SPECIFICATION:Magnification (with eyepiece supplied) x36Highest Practical Power (Potential) x400Diameter of Primary Mirror 200mmTelescope Focal Length 1000mm (f/5)Eyepiece Supplied 28mm LET (2"/50.8mm)9x50 FinderscopeParabolic Primary Mirror2" (50.8mm) Dual-Speed 10:1 Crayford Focuser0.5mm Ultra-Thin Secondary Mirror SupportsHEQ5 PRO Go-To Equatorial Mount with 1.75" Stainless Steel Tripod42,900+ Object SynScan Computer Database77% more Light-Gathering than 150mmPARABOLIC PRIMARY MIRRORSFeatures High Quality Parabolic Primary Mirrors to eliminate spherical aberrations inherent in 'fast' focal lengh reflectors with spherical primary mirrors. The mirrors are parabolized to bring all the light rays to the same focal point to give sharp, constrasty images, which are full of detail.SKY-WATCHER DELUXE MIRROR COATINGSMost reflectors today usually have a coat of aluminium as the mirror surface and then an overcoat of silicon monoxide or silicon dioxide to protect it. Silicon dioxide produces a much more durable coat than silicon monoxide but requires specialized equipment to apply it and is therefore more expensive. Protection is needed, because in most reflectors, the mirror is open to the elements and deterioration of the reflective layer reduces the resolution of the telescope.ALL Sky-Watcher reflectors are Multi-Coated with Silicon Dioxide as standard for Optimum Durability and Long Term Performance.We are looking for interested partners in South Africa and the Middle East to act as our agents
