The A

utoStar Computer Controller provides control of virtually every telescope function within

a compact handbox. AutoStar has soft-touch keys designed to have a positive feel. The LCD

(Liquid Cr

ystal Display) is backlit with a red LED (Light Emitting Diode) for easy viewing in the

dark. The backlit display, key arrangement, and sequential database make AutoStar extremely

user fr

iendly.
