Quote:A good review, except two issues the writer has with the mount are easily corrected: a) Vibration while focusing is indeed a problem for the ham-handed, especially if the scope is set up on a hard surface, like concrete. Setting up on a soft surface (a grassy lawn) helps considerably, as do Celestron's anti-vibration pads placed under the tripod legs. The ultimate solution is a motor-driven focusing device, such as JMI's Moto-Focus, which eliminates the shakes completely. b) Drifting of a target out of the field of view can also be completely eliminated by centering the target from the correct direction. In the northern hemisphere, ALWAYS center the target by moving it from the left side of the FOV toward the center. For vertical centering, initially try moving the target from the top toward the center; if it drifts vertically, instead center it from the bottom toward the center. When centered properly, it will remain near the center of the FOV for hours. See this Cloudy Nights article for further details: Method to Improve Tracking of Celestron Nexstar Although an AC adaptor will work, for observing in the field a 12 volt battery (Celestron Power Tank, jump start batteries, etc.) is the preferred power source. Finally, refer to the Celestron Nexstar Forum below for several years' worth of discussion about this mounting.- Tony Dralle
