说说折反的镜子哪国的好
各位同好：日本的折反镜好还是美国的？日本的调焦精度高还是美国的高？日本货的价格和美国的相比哪个低？怎么不见国内代销欧洲的镜子？ 你肯花錢的話,那國的都會是最高的,不肯花錢的話,那國都會有最爛的,國內代銷歐鏡的大把,想買嗎? 市面上流行的应该是俄国的好，例如IntesMicro的马卡、马牛镜。如果能淘到二手的，价钱也不贵。以下链接是我们这里一位同好用六寸IntesMicro马卡在大年初一夜里的观测记录：http://www.singastro.org/viewtopic.php?t=3080&start=0
“brief report from me:
- absolutely no dew for the whole night (don't even need dewshield)
- sky was not the best mersing can offer, but when the clouds cleared up, the view was pretty good
- highlights of the evening is orion region (m43,m42,m78,barnard33,rosette,witchhead,ngc1975,m1,flame), sombrero, m81, m83 galaxies, and eta carinae region
- our first time catching a glimpse of the horsehead nebula
- comparing my m603 to my previous C8s, the view is more pleasing due to better contrast and better optics (in and out focus of the airy disk pattern is almost identical), this makes up the 2" aperture difference.
- did a lot of eyepiece comparison on my f/10 scope:
-- 40mm XL vs 40mm XW vs 40mm MK70: the view is almost the same, XW slightly better in contrast
-- 21mm XL vs 20mm XW vs 22mm Pan: i can't see much difference, will keep my Pano
-- 11mm Nagler vs 14mm XL vs 14mm XW: i think it's a tie. has better widefield view on the Nagler, but the XL/XW is slightly better in contrast.”
当中提到6寸的M603有超越C8的表现。 這只是云云眾網民其中一位的看法, 是否有足夠代表性呢? :roll: :roll: :roll:
樓主所說的好, 是要哪方面好? 光學設計, 研磨精度, 反差高低, 口徑大小, 機械結構.......????? 就总体而言,而且上面也说了具体的:折射镜日本的调焦精度高还是美国的高？日本货的价格和美国的相比哪个低？ 相比较当然是相同口径的.
各位觉得是105口径威信的好还是美德的好? 哪种携带方便? 好像美德没有三脚架和箱子,得自己另外买.威信的两个都有,是吗? IntesMicro的马卡鏡是我見過的最好的，但具體是哪囯的，我不知道
威信和米德都不好，與 IntesMicro相比，都是高級玩具。 :lol: 米德的很好 。。。。上面說的太極端了，meadeetx 系列的光學質量還是不錯的 ^^ 我说米德的很好又没说他最好
