Abstract: Conventional Telescope Dome Shutter Control has bi-parting shutter driven by a AC three phase induction motor to which AC power is fed through circumferential busbars. These busbars frequently requires maintenance and some times hazardous to human being in case of open type busbars. A different approach is implemented to eliminate the use of busbars. The Power source required for Dome Shutter is made available on the Dome itself which will avoid the use of busbars. To have a simple and loss less Shutter Drive, a DC Source, by means of battery, is used to drive a DC motor through a Gear Box. The DC source recharged by a suitable Solar Panel fixed at outside of the Dome. Local control on the Dome Shutter Control Unit and remote control through Radio controls are available for Shutter Operations.
