马头很艳丽。背景白平衡不太好。
328镜头要锁一级光圈，那样会更好。讯号拉得强了些，缓和一点看看如何。颜色可以再艳些。

黃道光:

20081129 21:45UT, Nikkor AF-S 12-24mm DX f/4 @12mm開f/4, S5Pro @ISO800, 固定攝影曝光30秒.

去年也見到黃道光, 感覺上比今次還要光亮. 當日用肉眼可以見到一片三角形的暗光在山上. 照片中還可以看到亞米茄球狀星團正在東升.

"月齡2" is so poetic!
I can imagine "黃道光" is taken from another planet!

Should be the first P&S widefield astrophoto taken by a HK imager.

I have a GR1s, and it seems Ricoh does consider the lens performance with point source.

看來CD-1的表現真不錯
不要讓它停

我已经存着钱要买一个CD-1了...但现在日圆汇率高，现在的价钱提高不少了...

有没有多点CD-1拍摄的照片看啊？

冬季銀河:

20081129 17:19-17:51UT, Nikkor AF16mm Fisheye lens f/2.8D開f/4, EOS300D改, 300s x 6 @ISO800, CD-1.

由於西南方有清境農場的光害, 這張魚眼照片很難處理, 不過都post出來跟大家分享一吓.

Being boring at home, I dug out the Christmas Tree Cluster took in the Taiwan Trip in 2008 and processed it.

This time I only crop the very edge which is uneven and reveal 99% of the original image. The ED80 is not bad in the middle of the field but it makes up only about half of the whole image. Towards the edge coma kicks in tremendously.

I'm waiting for the dedicated field flattener to arrive and hope I can make a comparison then.
