  Piggyback Camera: Astronomy: Piggyback Camera - THE PIGGYBACK PLATFORM
Posted on Saturday, December 04 @ 17:46:10 CST by astronomy
  Piggyback Camera


The simplest platform is the barn-door tracker, a home-built contraption made of two wooden boards bolted to-gether. As you slowly turn the bolt, the "barn door" gradually opens up, swinging the camera from east to west across the sky.

Exposures of up to 10 minutes are possible. Detailed plans for barn-door trackers can be found in back
issues of most astronomyhobby magazines.

Any motorized equatorialg mount can serve as a platfon|| for a piggybacked camera. A few manufacturers market small "scopeless" mounts serve as dedicated camera platforms, but most people attach the camera to the of a telescope tube. Your scope mount may already hag an attachment bolt, or you can buy an adapter bracket.
