纯手动跟踪怎么办?这么老长的焦距,啥目镜倍数都低不了啊,在视野还不飕飕的跑。。。

wbhifi 2008-9-25 03:04

这个Dob是给一个在Taxes州的人定制的。 Dob结构是Obsession做的, 主镜是OMI的, 材料是通过Yuri(TEC老板)从俄罗斯进口的。 j-d kSr

这样的镜子除非你有固定的地点, 否则个人使用基本不可能。从我上次使用30寸的经验来看, 目视到了20寸就可以了, 再大效果提升有限, 但是麻烦却成倍增加。bbbb35

[b]哦,那这样看来如果要烧DOB那么Obsession 18" 是最合适的了![/b]~5i^o[C|?

其实12“对于大多数情况下都够用了, 嘿嘿。 详细点说, 对于星系这样的东东口径至少要加倍才能看到效果。 口径变大的时候, 效果最明显的是看弥散星云, 行星状星云,还有球状星团。

他们的镜头都是在美国磨制和镀膜的, 和老毛子没什么关系。 萤石是从德国Schott买的, FPL53是从日本买的, 其他材料也不错。 就是金工和AP相比稍微欠缺了一些, 至少TEC140是如此。bbbb15

最近大家在讨论AP140 vs TEC140, 看到Yuri和Roland都发言了, Roland对于TEC一直很赞赏。 结论就是: 目视为主,摄影为辅买TEC, 反之AP,嘿嘿bbbb15
