Shutter string extension

Since the shutter string won't reach the base of the Rastrocam after being passed through the body tube, I tied a piece of shroud line cord long enough to reach past the notches in the stage coupler on the base of the Rastrocam. For flight, I cock the string by pulling it through the notches and put the Rastrocam into the carrier rocket's tube. Friction between the stage coupler and the body tube will hold the string until ejection. The dent in the body tube near the string's exit hole was caused by a fall from several hundred feed after the parachute separated from the camera. This thing's pretty rugged, but I don't recommend that type of recovery...
