[edit] Tower

Anyone know what the tower is for? The HET website doesn't say. --BjKa 10:20, 29 January 2007 (UTC)

The tower contains instrumentation for monitoring and adjusting the mirror segments. Periodically the telescope is pointed toward the tower, measurements are made, and the mirror segments moved to place them in optimal positions. Bill Jefferys 23:09, 16 April 2007 (UTC)


[edit] Photo

The caption for the photo gives one date, but the information from the camera metadata gives a date several months earlier. Can the person who contributed this photo clarify?
