Dome

We have some continuous problems with a oil leak from the return flow pipe of the motor of the upper hatch. The area is difficult to access and we are looking at how best to repair this. Only the telescope structure is affected, not the main mirror, and for the moment we have only cleaned the affected areas as much as possible.

As part of making the operation of the telescope more automated and improve the safety of the telescope a system is being designed to automate the closing of the side-ports.
