Sky-Watcher Quattro 200P 8" Imaging Newtonian - S11210
Highlights
- 205mm aperture, 800mm focal length
- Fast f/4 focal ratio
- Parabolic mirror designed for imaging with 94% reflectivity
- 10:1, dual-speed, 2-inch Crayford-style focuser
- Oversized secondary mirror produces greater illumination for full-frame DSLR and CCD cameras
- Tube rings, mounting plate, eyepiece adapters, and 9x50 finder scope included
The new Sky-Watcher Quattro Imaging Newtonian with dual-speed focuser incorporates a superb mirror-set with two significant advantages over competing products. A 2" dual-speed 10:1 ratio focuser is included for excellent focusing precision. Additionally, the tube length has been slightly shortened to optimize performance for prime-focus photography.
Even better performance for astrophotography, and visual use, can be achieved when used in combination with the Sky-Watcher Quattro coma corrector.
