BPAA Photographs

[Helix House and Dome]   [Astronomy]   [Ritchie Telescope]   [Meetings and Events]  [Miscellaneous]  [Astronomy Day]

This web site makes a valuable contribution to our members by serving as a repository of photos of the many BPAA activities.  The photos are displayed on linked pages with handy buttons at the bottom to let you leaf through all of our photos.

In addition to this online repostitory there is a much more extensive traditional photo archive maintained by one of our members that contains photos showing various events in the history of BPAA.    

The Helix House at Battle Point Park

contains the Edwin E. Ritchie Observatory and serves as an educational facility operated by the BPAA.  When construction started, the building was an empty shell.  Today, the building is a two story facility ready for use.
