H-alpha 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.

H-alpha dome

The small dome contains a single telescope mount with two telescopes. One telescope is used during the day to observe the full disk of the Sun in hydrogen-alpha (H-alpha) light. The other telescope is used to observe earthshine -- the light reflected from the Earth to the Moon and back. The brightness of the earthshine is related to the amount of cloud cover over the part of the Earth providing the light to the Moon.
