Rumors: new special Nikon D810 version designed for deep-sky astrophotography
with increased hydrogen-alfa sensitivity
Here is a rumor that just came in: next week (probably on February 2nd or
3rd), Nikon will announce an all new, special version of D810 DSLR camera
designed for deep-sky astrophotography with increased hydrogen-alfa
sensitivity.
Given the short notice, I do not have enough time to get any confirmation
from other sources. Because of that, I will give this rumor a probability
rating of "only" 60%.
Back in 2012 Canon did something similar with the EOS 60Da model.
Nikon has several articles on astrophotography on their website.
大致上就是2012年卡人曾经推出60D的星空摄影特别版60Da
增加对Hydrogen-Alpha (H-α)敏锐度
使得低光长时曝光能有更纯净的画质、更少的噪声
而目前“有60%可能”要推出的D810特别版
以135的片幅及更强悍的尼控技术
相信会比60Da的画质还翻了数倍

2015-02-02 12:58:00应该跟纯净度和画质没有太大关系 而是可以拍到部分红外线光谱

2015-02-02 15:08:00楼上在说啥...这是推专业用机又不是D810下一代...挤压膏是说下一代和上一代差异不大没太多新的spec...不要乱用挤压膏这词... 那Canon 60Da怎办?
有些人就是不甘寂寞，只有canon挤牙膏太无聊，硬要拖nikon下水

惨了，前几个月才推朋友买P家配O-GPS拍星空，这下害了他...

好像还是改机比较好?

2015-02-03 23:32:00主要是让H-alpha通过多一点 现行CMOS前的IR-CUT 会档掉超过70%的 H-alpha要分出星星和噪点 可以比较星点经过镜头的点扩散状况
