[b]The C5+ incorporates a 9 volt DC battery powered drive and runs for about 50 hours! Thus the telescope can operate anywhere on Earth (in the Northern or Southern hemispheres) independent of local available electrical power. The electronics of the C5+ also are furnished with a built-in drive controller and a hand control. The R.A. motor's main tracking speed is an accurately regulated sidereal rate. The hand control allows fast and slow speed override of R.A. tracking speed and +/- operation of the optional DEC motor.[/b]
