About this product
Part Number: 10220/20886
The new Sky-Watcher Explorer-200P DS has the same superb parabolic primary mirror as the Explorer-200P but features a 1.25"/2" Dual-Speed 10:1 ratio focuser for enhanced focus control and a shorter tube length with the secondary mirror positioned closer to the primary mirror for more convenient prime-focus photography.
Parabolic Primary Mirror
All Sky-Watcher f/5 (‘fast’) Newtonian Reflectors and Dobsonian models feature high-quality parabolic primary mirrors to eliminate spherical aberrations inherent in ‘fast’ focal length reflector. The mirrors are parabolized to bring all the light rays to the same focal point to give sharp, contrasty images.
Ultra-Thin Secondary Mirror Supports
All Sky-Watcher f/5 Newtonian Reflectors feature 0.5mm ultra-thin secondary mirror supports to reduce diffraction spikes and loss of contrast.
