Observatory Operation Basics Thomas C. Smith, Director, Dark Ridge Observatory (

The Observatory Fundamentally the observatory is the collection of equipment and software necessary to perform astronomical observations and research. Fundamentally the observatory is the collection of equipment and software necessary to perform astronomical observations and research. In our case we are talking about the physical observatory building and dome, the telescope, the computer, the CCD camera, and software for system control and processing of image data.

The Observatory Dome Operation of the observatory dome is a matter of opening the dome shutter and coordinating the position of the dome in azimuth to correspond to the telescope point. Operation of the observatory dome is a matter of opening the dome shutter and coordinating the position of the dome in azimuth to correspond to the telescope point. Cuesta’s dome is electrically operated but manually position. Cuesta’s dome is electrically operated but manually position. It is imperative that dome operation be conducted safely for both personnel and equipment protection.

The Computer The computer is used as the system coordinator and enables the telescope and CCD camera to operate effectively through software. The computer controls the CCD camera operation and the movements of the telescope from within the planetarium software we are using.

The CCD Camera The CCD cameras used will be either the Santa Barbara Instruments Group (SBIG) ST-402 monochromatic imager, Starlight Express one-shot color imager or the Meade Lunar Planetary Imager (LPI). The CCD cameras used will be either the Santa Barbara Instruments Group (SBIG) ST-402 monochromatic imager, Starlight Express one-shot color imager or the Meade Lunar Planetary Imager (LPI). All three imager models can be used as an auto-guiding imager but the ST-402 can not be used as both imager and auto- guider concurrently.
