Observing floor

The observing floor should be lowered before moving the telescope. Push the yellow handset buttons on the observing floor to bring it down. If the floor doesn't move, check that all the safety switches are released (check ladder and metal door). Clear the floor such that the telescope cannot run into things like steps and dewars.

The telescope is affected by movement on the rising floor. It amounts to a movement of the image of a few arcsec if the observer jumps up and down. Keep off the rising floor when exposing unless absolutely necessary.
