Video Recording Rig.
Designed for efficient observing occultation events.

If there is a word to describe a good occultation observing rig, be it home/observatory based or for mobile observing is efficient. Any delay in setting the rig running, be it missing, damaged or missmatched components must be fixed, replaced or eliminated. To miss an event due to someone borrowing a cable is a tradgedy. Everything must have it's place and everything must be in it's place, ready to go. This is my latest attempt at a PC based solution.
