2003年8月11日-12日雁翅观测活动


8月11日,立秋刚刚过去,北京迎来了难得的大晴天。同好会抓住此机会前往京西门头沟区雁翅镇进行观测。

这个地点是天文爱好者刘宁的一个个人观测点,晚上10点左右,齐锐,吴志伟,尹相东,寇文,于杰鸿,王炎,高松青,孟奂和朱进、刘宁抵达雁翅。朱进一直在物色一些地点供天文馆组织科普活动时使用,这次带来了天文馆的高桥FSQ106折射望远镜,米德203折反望远镜做一番实地观测。

由于大地被太阳暴晒了一整天,即使在空气较好的山区大气还不是很稳定,在观测的后半程宁静度渐渐好了起来。大家用几架望远镜分别进行了目视和照相观测。 刘宁自带了BOSMA203牛顿反射望远镜,但像质有些问题,虽经尹相东仔细调整效果仍不理想。

使用尹相东的NIKON CP4500与高桥FSQ106配合拍摄火星,在LCD上可以观察到锐利的火星像,看上去比直接目视舒服。

高松青和寇文共同试验了CCD相机。这是邱虹云自行设计制作的半导体制冷天文摄影用CCD相机,小高为之重新加工了隔离的金属外壳,彻底解决了制冷结露问题。相机长时间曝光拍摄深空天体的能力很强,但因没有视频模式,给调焦带来不便。

因为第二天大家还要上班,凌晨2点左右陆续到附近旅游点的房间休息去了,而孟奂则在凌晨开始观测英仙座流星雨。
