• Last BASS Meeting: May Meeting There were several requests for the power point from the meeting on observing galaxies in the spring, you can download a copy here.

• Astronomy Day :  Saturday April 24th, @ Sommers-Bausch Observatory and Fiske Planetarium on the CU Boulder campus.  A huge thanks to all who helped out at this event! The stormy weather cleared for just that afternoon and evening, helping to make it a huge success. There was much solar viewing and a great evening star party on the SBO observation deck with a few hundred new friends.

Ethos meets FirstScope - BASS pushes the limits of new equipment testing at the September meeting!

Possibly a first, $600 eyepiece on a $30 telescope. While not exactly compatible, both components do have their merits!
