Jazz Under the Stars
****December 7th Jazz Under the Stars is CANCELED****
Jazz Under the Stars is a FREE monthly public stargazing event! Occurring on the Saturday nearest the 1st quarter moon (check our Events Page), join us in Building 36 on the 4th floor observatory for a night of smooth jazz, bright stars, and a lot of fun! We play our jazz from CSM's own KCSM 91.1. Founded in 1964, KCSM has grown to become one of the top 35 most listened to non-commercial stations in the US. With their help, the Astronomy department at CSM opens its observatory doors and balcony, for a night of science and fun! We operate for public viewing 8” dobsonian telescopes, prefect for viewing the planets Venus, Mars, Jupiter and Saturn. We also have a 140mm refractor, with which we view the craters on the moon. Finally, our 11’ schmidt-cassegrain is for our deep sky needs. It can peer deep into globular clusters, and nebulae. Occasionally we even have the chance to image galaxies on our 20" telescope. Our astronomers will also be available for questions and conversation, which you wouldn’t get anywhere else! Feel free to ask us your questions about the cosmos. Don't miss out, join us at our next Jazz Under the Stars!
*Weather in the bay area is notoriously hard to predict, and often the sources we use don't get it correct. Before leaving you home, be sure to check this webpage. If we are to cancel it will be posted here at least a few hours before the start of the event.*

Cameras for Allsky Meteor Surveillance (CAMS) - A SETI Project
CAMS, a SETI project, is an automated video surveillance of the night sky to validate the International Astronomical Union's working list of meteor showers. It's mission is to discover previously unknown meteor showers and to triangulate and locate meteorites. CAMS was founded in 2010, but established at CSM in 2012 in connection with Peter Jenniskens, Senior Research Scientist at the SETI Institute. CAMS has over 80 camera's in the Greater San Francisco Bay Area, and over 260 cameras worldwide. This mission has led to the discovery of over 60 new meteor showers including Delta Mensids, February epsilon Virginids, and R Lyrids.

Fireball captured on CAMS camera - CSM Observatory
Our observatory's CAMS video camera captured a bright fireball over the Bay Area on the local evening of 10-17-12. This looping video shows the Oct. 17 fireball, with a field of view ~28 degrees. Six meteorites were discovered from triangulating data from CSM and Santa Rosa. All six meteorites were found in the town of Novato, located about 45mins north of San Francisco. These meteorites were discovered to have a previously unknown class of metal-organic compounds known as dihydroxymagnesium carboxylates. Link to SETI article. Special thanks to Dave Samuels in processing/managing CAMS data. See the latest CAMS update.
We image nightly with a single, Watec 902 H2 Ultimate video camera, producing a 26.8 x 22.1 degree FOV centered on Azim (deg) 263.205, Elev (deg) 47.283. Processed data is available for student analysis, and sent to Dr. Jenniskens. Check out this sample video of the Quadrantids meteor shower taken January 4, 2012.

The Observatory
Our observatory at CSM has quite a unique design! Unlike the usual dome shaped observatories, our "roll-off" roof looks like a regular roof, but with the flip of a switch, retracts so that the entire surface area of its floor is exposed to the outside. The advantage of this design, is that more telescopes can be used simultaneously, and the observatory can quickly reach thermal equilibrium. This results in steadier views through our telescopes. Our observatory currently has five permanently mounted telescopes, and 14 mobile telescopes. Here are some of our favorites:
20" RC Telescope
General Information:- Reflector Telescope
- Aperture: f/8
- Field of View: 15.6x23.4 arcmins
- SBIG STL-6303 CCD
- Chip Size: 18.4x27.6 mm
- Pixel Size: 9u x 9u
Our 20" Ritchey-Chretien telescope from RC Optical Systems delivers quality images of the night sky. The RC sits atop a Paramount ME mount for location and tracking of distant objects. Attached is an SBIG STL-6303 CCD camera for imaging deep sky objects and measuring stellar magnitudes. A 500mm Borg refractor rides "piggyback" on the 20."
140mm TEC Refractor
General Information:- Refractor Telescope
- Focal Length: 980mm
- Field of View: 35.1x52 arcmins
- SBIG ST-10E CCD
- Chip Size: 10x14.9 mm
- Pixel Size: 6.8u x 6.8u
- Losmandy Titan mount / Gemini controlled
Students and visitors enjoy superb views through our 140mm TEC refractor. Refractors like this are great for viewing planets, comets, and other solar objects. Visitors to "Jazz Under The Stars" can also enjoy close-ups of lunar craters and mountains.
10" Spectroscope
General Information:- Schmidt–Cassegrain Telescope
- Focal Length: 2000mm
- Focal Ratio: f/10
- Field of View: 11.9 x 7.9 arcmins
- SBIG ST-7XME-S CCD
- Chip Size: 6.9x4.6 mm
- Pixel Size: 9u x 9u
- Losmandy Titan mount / Gemini controlled
If you're looking for real science, our spectroscope will be your favorite! It's special camera takes light from different stars and separates them into their component wavelengths, showing us various peaks. These peaks correspond to specific warelengths that help us to identify different elements, allowing us to "look inside" a star! With this amazing equipment we can calculate radial velocities, doppler shifts, and and what type of start we're observing.
180mm TEC Refractor
General Information:- Refractor Telescope
- Focal Length: 1260mm
- Field of View: 50.2x75.3 arcmins
- SBIG STXL-6303 CCD
- Chip Size: 18.4x27.6 mm
- Pixel Size: 9u x 9u
- Losmandy Titan mount / Gemini controlled
Large galaxies like the Andromeda galaxy, are often too large spatially in the sky, for our more sensitive telescopes to get a full picture of. This is where out 180mm TEC refractor comes in. It has an extremely large field of view, allowing us to image almost the entirely of Andromeda as well as other many large objects!
