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年卡人曾經推出60D的星空攝影特別版60Da
增加對Hydrogen-Alpha (H-α)敏銳度
使得低光長時曝光能有更純淨的畫質、更少的雜訊
而目前「有60%可能」要推出的D810特別版
以135的片幅及更強悍的尼控技術
相信會比60Da的畫質還翻了數倍

2015-02-02 12:58:00應該跟純淨度和畫質沒有太大關係 而是可以拍到部分紅外線光譜

2015-02-02 15:08:00樓上在說啥...這是推專業用機又不是D810下一代...擠壓膏是說下一代和上一代差異不大沒太多新的spec...不要亂用擠壓膏這詞... 那Canon 60Da怎辦?
有些人就是不甘寂寞，只有canon擠牙膏太無聊，硬要拖nikon下水

慘了，前幾個月才推朋友買P家配O-GPS拍星空，這下害了他...

好像還是改機比較好?

2015-02-03 23:32:00主要是讓H-alpha通過多一點 現行CMOS前的IR-CUT 會檔掉超過70%的 H-alpha要分出星星和噪點 可以比較星點經過鏡頭的點擴散狀況
