An electric focuser is almost essential if you want to stop your telescope from jiggling about while making fine focus adjustments.
The Skywatcher electric focuser gives you variable speed adjustment and runs from a 9V battery (supplied). They can be fitted to almost any telescope using the multifit bracket they come with.
