Main Dome

Real tours of the observatory for the 2009 summer season have not yet been finalized. Once the new telescope is in place tour scheduling decisions will be made. At this time no tours are scheduled.


The main dome of Big Bear Solar Observatory was originally built in 1968/1969. The dome itself was a steel 30-foot diameter hemisphere. In 2005 the old dome was replaced with a 34-foot 5/8-sphere fiberglass dome to accomodate the NST.
