Automation of Astronomical Telescope: II. Development of Techniques Equipments and Softwares for Remote Control of Telescope
As a continuing effort to develop an automatic control system for small telescope, we developed the software for telescope control and CCD observations under DOS operating system. For accurate pointing of the telescope in short amount of time, we modeled the angular speed of the telescope by a quadratic function of time (constant acceleration)for the first 15 second and then linear function of time (zero acceleration)afterwards. By changing the telescope speed form 'slew' to 'fine' before the telescope reaches the desired position, we could achieve the accuracy of a few arcseconds. The CCD control software was written for model CCD-10 of CCD Technology. This CCD can be used for guiding purposes. We also conducted the study for remote control of the telescope using telephone line. Although it cannot be used for real observations at the present form, we succeeded in remotely pointing the telescope to desired direction. As faster communication technologies become widely available, simple observations can be made remotely in the near future. Finally we report some observational results made with the present control system.
