This file can be input directly into a spread sheet program for graphing and data analysis. The system is currently being used to measure light curves of eclipsing binary stars. Figure 1 shows a representative sample of the photometry this system can achieve using one minute exposure times. The eclipsing binary star BX Draconis has a V magnitude of 10.6. We believe this feasibility study has proven the concept of using the Meade LX200 and SBIG ST-7 CCD camera in a robotic observatory.
Many questions still remain concerning the reliability of such inexpensive equipment.
Even if components such as telescope motors and gears break or wear out, replacing them is quite inexpensive. Given the low purchase price of the camera and scope, spares could be kept on hand should problems occur. Given that fact, the most difficult parts of this project were software development and the design and construction of the enclosure. The lid opening mechanism was designed and then redesigned until a working, reliable method was found. Sealing the lid against rain and snow was also a challenge which was not met without some reworking.
