Yesterday we hoisted the camera and cold optics back up into the telescope; today we finished putting all the electronics back up there and plugging it all back together (which involved plugging in more than 250 connectors and screwing them together so they won’t come loose). So, the camera is back on the telescope, and we’ll be do observing tests!

Video: using the chain hoists to lift the receiver and secondary optics up into the telescope. This is not as much fun as it looks like. 🙂
