- Abstract
For the development of the optical observation technologies on space debris, Institute of Space Technology and Aeronautics(ISTA),JAXA, has been preparing the optical observation facility at Nyukasa-yama mountain in Nagano Prefecture. 35cm Nywton-type optical telescope on the equatorial mount in the 3-meter dome has been operated. The facility was built at an altitude of about 1,800 meters and it can provide the best optical environmental conditions for faint objects observations. The detectable star magnitude is about 19-magnitude and 21 magnitude-class asteroid could be detected by this small aperture telescope by using the stacking method developed by authors. High speed read-out and high efficiency back illuminated CCD cameras with 1Kx1K and 2Kx2K elements were used and 4Kx4K CCD camera was developed. The first two cameras were cooled by perche devices and the latter large CCD camera was cooled by a sterling engine refrigerator. For the future remote observations, 25cm small telescope with the 4Kx4K CCD camera in the 3-meter dome was newly set up at the observation site this year(2005). The field-of-view(FOV) is 2.5deg.x2.5deg. This paper describes the characteristics of the small optical observation system, i.e. optical telescopes, detecting CCD cameras, cooling component, detecting software and the evaluation results of the facility capability by using the observation data.
