【新人求助】目镜购置 celestron skyprodigy 130
大家好, 我想请教一下这个镜子买什么目镜配置比较合适celestron skyprodigy 130
焦长:650mm
焦比:5
口径:130mm
结构: 牛顿反射望远镜
前些天刚买了个ES 68 24mm,还有原装的9和25
想添置其他的目镜。刚刚开始学些天文望远镜的使用,打算先买3-4个目镜练习。
查了一下网上的介绍A Treatise on Optimizing DSO Observation,大概需要覆盖出瞳1mm, 2mm, 5-7mm。我也不知道这个理论合理吗,希望大家指点。
我主要是想学习天文知识,深空和行星都想接触。
很多人都说短焦的要买结构简单的,是不是就是不要买广角的?
如果想尽可能的覆盖比较全面的焦段,买哪些合适?
下面的是借用网上的模板填进去的数值。
希望有人能指点一二,谢谢啦{:3_208:}
