(1) Fresno State's Campus Observatory.

Click the following for:

The Campus Observatory is on the grounds of the Downing Planetarium, at longitude 119.7447 degrees West, latitude 36.8147 degrees North, and elevation 340 feet (104 m). (The local mean time correction is +1m 01.3s.) Its main telescope is a 16-inch Meade LX200. The Campus Observatory is well instrumented, with a wide variety of cameras and other equipment. For an equipment list and a description of their performance, see here.

Science programs include:


If you're interested, please read the following:
On many projects we collaborate with the Central Valley Astronomers, Fresno's amateur club, who are a huge help!

If you are a Fresno State student or CVA member and have your own ideas for projects, particularly if they describe a specific, plausible path from telescope to finished scientific objective, which we can do with the equipment we have now, please contact Professor Ringwald.

Please note: Fresno State's station is now permanently CLOSED.

This is because Professor Ringwald will be retiring on 2026 July 1.

The other observatories at Sierra Remote are alive and well.


The first eight Sierra Remote Observatories were built in 2007. The project was founded by Dr. Greg Morgan, Dr. Keith Quattrochi, and Dr. Mel Helm, all of whom were members of the Central Valley Astronomers. The observatories are at a dark site at 4610' altitude, near Shaver Lake. Fresno State's telescope was in Observatory #7. My students are I operated it mainly from campus, 41 miles away, by remote control over the internet.
