Celestron Dobsonian 12 |
| Celestron is proud to introduce our Star Hopper series of Dobsonian telescopes available in 6inch, 8inch, 10inch and 12inch apertures. Dobsonian telescopes are recognized within the astronomy hobby as an excellent value for the aperture size, and our Star Hopper line is as rich in features as it is in value. Our Dobsonian configuration is a Newtonian optical tube mounted on an altazimuth mount. The optical system features a large primary mirror at the bottom of the tube which collects light and concentrates it onto a small secondary mirror, which reflects the light out the side of the tube and into the eyepiece. Best of all, Star Hopper Dobsonians are easy to observe with -- the user navigates through the night sky by simply moving the tube up or down, and left or right, by hand. All Star Hoppers use optical quality BK-7 glass, this is the same high-quality glass used in most binocular prisms and refractor telescope lenses. All Star Hoppers use a roller track bearing on the azimuth surface providing dozens of support points for smooth swivel motion. They also use a variable tension clutch system for proper balance and control in both altitude and azimuth. The 10inch & 12inch Star Hoppers have cooling fans built-in to the rear cell to decrease cooling times. The 8inch, 10inch & 12inch models come standard with 2inch focuser and 1.25inch adapter. The 10inch & 12inch models come standard with a 32mm 2inch eyepiece and use a 9-point flotation mirror cell for equal support of the primary mirror. Key Features: 12inch Primary Mirror. 60inch Focal Length. BK7 Optical Quality glass. Roller Track Bearing on Azimuth Surface provides dozens of support points for smooth swivel motion. Variable Tension Clutch System for proper balance and smooth control in both altitude and azimuth. Includes 32mm e-lux 2inch eyepiece and 9 x 50 finder scope.
