BUSHNELL博士能的天文望远镜好么？788846和788831哪个好？
偶是菜鸟，DX们帮帮忙，最近想买一个天文望远镜，不过我这里不像国内买不到那么多的牌子（偶在澳洲），现在能看到只有BUSHMASTER和BUSHNELL.不晓得BUSHNELL的怎么样，现在有这么两款我看还可以，788846的简介（国内网上报6000块大洋，我这里现在打折大概3000左右）：

788831的简介（国内网上报5000块大洋，这里打折后大概2400多）：

这两款好像可以自动寻星？具体见介绍，好像说只要输入要找的星就可以自动跟踪之类的，很多专业名词我不太懂。

偶是十足菜鸟，买个来为了消闲娱乐，请各位DX帮忙看看到底值不值，因为这东西太重，不太可能从国内背了去（一趟飞机一共才能带30公斤的东西）::070821_20.jpg:: ::070821_20.jpg:: ::070821_20.jpg::
[ 本帖最后由 horus 于 2007-12-26 21:37 编辑 ] 怎么感觉像晶华的N114/900加上电跟？ 本来就是么，这个牌子的镜子好多就是国内给OEM的 那这样的价格这样合算么？对于初学者？谢谢
