I want to understand why you say such thing to me.

Please reply in PM.

睇真D，原來D300有liveview，其中的Tripod mode live view好似好有用，D300 build-in已經有類似FWHM的功能，而且可以在notebook上用LCD來對焦。

今次我buy這個功能。


Tripod mode is designed for precise focus accuracy with still subjects and tripod stabilization. In this mode, focal-plane contrast AF on a desired point within a specific area is possible. Remote view, focusing and shooting are also made possible on a PC (wired or wirelessly).

如果D300無埋Nikon機的天文死穴amp glow，真係諗得過。

睇下睇下真係有D心動及衝動。

其实Nikon个死穴已经控制得好好多啦，要彻底减至最低，就要睇下Nikon是否好似Canon那样，有兼顾及考虑到天文摄影。

我只有1架DSLR，Nikon D70，佢的amp glow真係好難攪。就算用dark frame減去amp glow，amp glow的2個位, signal一定會少了。一張相還好，如果想做mosaic，會好容易見到原來的amp glow位, 光暗明顯有分別。

[universe24]

这个型号是比较差的啦。不单只signal少了，而且减除后还会变色，用那个NR function又会把小星星一并减去...
我试过用D40x来暗3分钟dark，温度大概28度左右，其amp glow明显减少了，平均分布在照片的4角，noise就...颇严重。

I have a Nikon D 80. I do not know if it is suitable for astrophotograhy. Can anybody give me some advise??

[XR250]

syyuen168，其實架架DSLR都可以用來影天文相的，只不過有些型號(e.g. 20Da/mod. 300D)比其他機好。

我用架D70都係咁影啦，你的D80緊係無問題啦。只不過D80影紅色天體，無咁"現"。

Do you think mod 350D is better than mod 300D? I love its lightweight.

佢個新body，只係占了成個trip及器材，好少好少部份。

都係要等實物出現，睇下真實相片samples先諗下點。

無錯, 貓姐係d買部機去旅行影靚相果d人, 而唔係equipment driven, 相機對佢來講只不過係一件工具, 所以佢跟本唔會理呢d minor嘢.

感就buy部D300啦, 你絕對有理由上D300.

[XR250]

如果只係日間影相，唔理天文，直接去買就S5Pro就得啦。我話買D300係因為上面個liveview function可以用在天文上，但如果H-alpha又係乜都過唔到，amp glow又鬼咁勁。咁就買唔落手。

雖然300D的pixel比350D大小小，理論上對天文攝影有利。但如果我買來改，我會選350D而唔買300D，主要係因為電量問題。
