DEVELOPMENT OF CONTROL SOFTWARES FOR IMPROVEMENT OF TRACKING EFFICIENCY OF THE 16'' TELESCOPE OF SEOUL NATIONAL UNIVERSITY OBSERVATORY

서울대학교 천문대 16인치 망원경의 추적 성능 향상을 위한 제어 소프트웨어의 개발

We have improved the control and driving system of 16' reflector at Kwanak Observatory at Seoul National University, by completing encoder unit, and by developing programs for correction of errors resulting from hardware defects. The hardware defects of this telescope system are the large backlash and the nonuniform tracking and pointing. The telescope pointing accuracy for RA is improved to a few arc minutes, and that for DEC is several tens of arc minutes. The guiding error is improved to 0.7 arcsec/minute, allowing up to 3 minutes exposure for CCD imaging under typical seeing conditions at the Observatory.
