superior due to the elimination of extra readout noise and the residual blurring caused in realigning the images.

When taking long exposures with astronomical telescopes, motorized tracking is required to compensate for the Earth’s rotation. Most telescope mounts do not track accurately enough for long-exposure imaging without some form of additional “guiding”. Manual guiding can be done by an observer watching a star (“guide star”) through a telescope (“guide scope”) mounted next to the main imaging telescope (on the same mount). The observer makes manual corrections to the motor drives via a pushbutton hand controller to keep the star centered in the guide scope’s eyepiece over time. In this way the track- ing accuracy of the main telescope (with imaging camera attached) can be assured. Stars in the resultant images will be crisp and round. Manual guiding
