Part of the Patrick Moore's Practical Astronomy Series book series (PATRICKMOORE)


Previous chapters have described how to optimize your telescope’s balance, minimize backlash in both axes, obtain good polar alignment, and minimize the mount’s natural periodic error. It really is important to optimize all of these parameters before serious attention is given to autoguiding, for reasons that will become apparent in this chapter. By now, even without autoguiding you should already be able to take a series of pictures with your CCD camera, exposing each for at least 1 min, preferably rather more, and expect the majority to be decent images with round stars.
