Celestron - Starhopper 12 Dobsonian

Dobsonian telescopes are recognized within the astronomy hobby as an excellent value for the
aperture size, and our StarHopper line is as rich in features as it is in value.
	
Celestron’s 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, StarHopper 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 StarHoppers use optical quality BK-7 glass, this is the same high-quality glass used in most
binocular prisms and refractor telescope lenses. All StarHoppers 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
10” & 12” StarHoppers have cooling fans built-in to the rear cell to decrease cooling times. The
8”, 10” & 12” models come standard with 2” focuser and 1.25” adapter. The 10” & 12” models come
standard with a 32mm 2” eyepiece . 12” StarHoppers use a 9-point flotation mirror cell for equal
support of the primary mirror.

	

Providing a serious 12" aperture for a serious value, this Dobsonian telescope is the
largest in the StarHopper Series. Like all StarHopper models, this telescope features optical
quality BK-7 glass, the same high-quality glass used in most binocular prisms and refractor
telescope lenses. It uses a roller track bearing on the azimuth surface providing dozens of
support points for smooth swivel motion and a variable tension clutch system for proper balance
and control in both altitude and azimuth. 
This 12" StarHopper has a cooling fan
built-in to the rear cell to decrease cooling times and comes standard with a 2" focuser, a
32mm 2" eyepiece and 1.25" adapter. The StarHopper 12 uses a 9-point flotation mirror
cell for equal support of the primary mirror.
