The fan operates when a special power cord (supplied in the accessory box) is plugged into the fan unit of the telescope and the12v DC OUT (13E, Fig. 1) of the computer control panel with the power switch in the "ON" position. The amount of time required to stabilize the temperature will be dependent upon ambient conditions including the observation site and preexisting condition of the telescope. The fan should be activated at the beginning of the observation session to accelerate the temperature stabilization. As soon as the optics have reached an equilibrium with the environment the fan should be turned off by unplugging the fan power cord or by turning the power off in the AUX Port Power menu. Fan operation time should range between 5 and 25 minutes. While it is permissible to run the fan continuously it is not recommended because the very slight vibration of the fan may cause noticeable movement of the objects observed in the sensitive optics. 8" f/10 LX200GPS Specifications Optical design Schmidt-Cassegrain Clear aperture 203mm (8") Focal length 2000mm Focal ratio (photographic speed f/10 Resolving power 0.56 arc sec Coatings Meade EMC Super Multi-Coatings Mounting Cast-aluminum, double-tine forks Gears 5.75"-dia. worm gears, both axes Periodic Error Correction Both axes Alignment Altazimuth or equatorial w/optional wedge Pointing Precision 2 arc-minutes in GO TO mode Slew Speeds 1x sidereal to 8°/sec in 9 increments Power 8 C-cell (user-supplied) batteries or optional 12v power supply Tripod Variable-height field tripod Accessories 8 x 50mm viewfinder 1.25" diagonal prism Super Plössl 26mm eyepiece 4-speed zero image-shift microfocuser 16-channel GPS receiver True-level electronic sensor Net telescope weight 46 lbs.
