天文望远镜的朋友慢慢看一下,毕竟买了镜子的人都不希望用几次就没兴趣再用,扔在一边浪费着.
首先：SAKURAaum不要误人子弟.
流星的出现位置是随机的,而且划过天空很大的跨度,想用天文望远镜捕捉它的影响,几率太小了.（你可以想象自己通过一个纸管看着天空,然后期望着有一只苍蝇正好经过你的视场.)
所以流星和流星雨一般都是用肉眼直接观测的.流星雨只是辐射点确定,但是流星本身出现位置并不确定.
天文望远镜的集光能力强,但是视场是很小的,主要用来观测位置确定的天体.
天文望远镜可以：
1、观测月球表面（建议增加月亮镜或缩短目视时间,因为月亮较亮,长时间通过望远镜观测,会引起眼睛胀痛）；
2、投影法观测太阳黑子和金星凌日（切勿直接用眼睛通过望远镜看太阳,会失明!也不要将望远镜长时间对准太阳,避免过热损坏镜子,原因参考“放大镜聚太阳光点火”的原理）.
3、观测其他天体,对于这个可观测的天体目标,大部分刚使用望远镜的同好都有一个误区,喜欢用望远镜来观察那些亮星.其实恒星离我们太远,即使用更大的望远镜来看,依旧也只是一个光点而已.
我们应该用望远镜来看那些：
3-1、星团、星云、星系等：他们都不是点光源,用望远镜的适当倍率,可以看清一点细节,比如猎户大星云、仙女座大星云（实际是星系）、昴星团（七姐妹星团,眼睛极好的人才能看到第七颗,实际上那个星团是由很多很多颗星组成的）等.
3-2、暗弱的天体：人眼极限星等6.5,一般用望远镜能够看到7至11星等的天体.这样可以观测到更多暗弱天体,而这些天体中隐藏着很多的星云、星团、星系、造父变星等特殊天体.
3-3、难以辨认的天体：人眼的最小分辨角度是1分（1'）,用望远镜将天体的像放大之后,原本极其相邻的天体间的距离扩大了,人眼就能分辨出来是两颗星了.最好的例子就是双星系统和卫星.双星是两颗相近的恒星彼此绕转,组成一个相对稳定的天体系统,比如北斗七星中的开阳星,它的旁边有一颗很暗的星“辅”,两者之间相距11分(11'),中外的军队在古代都将开阳用来测试士兵眼力,只有能通过肉眼看出他们是两颗星的才是好眼力.另外中国古人甘德曾记载其观测木星时“若有小赤星附于其侧”,实际上就是指木星的卫星.而伽利略在将近两千年后才用望远镜观测到木星原来是有卫星的,因为二者距离极其相近,木星又过亮,让人极难通过肉眼看到木星卫星,而望远镜就能够解决这一难题.再有就是星团,肉眼看是几颗星,望远镜中看到的可能就是上百颗.
3-4、行星：木、火、土、金等在一定倍率下,可以看到有一定面积的像,土星光环也清晰可见.
除此之外,我们还可以外接照相机,进行天文摄影,没有照相机的,用摄像头略微DIY一下,也能进行拍摄.天文摄影,相对于单纯的观测来说,有作品,让我们更有成就感,而且可以与朋友分享你的所得,乐趣无穷.
