天開了，拿著CD-1上大山，插電開機便"咯...咯...咯...咯...咯...咯..."的響，五十米外也聽到，連個ball head都跳跳下。回家打開發現Vixen driver內的 NPM Motor 中軸跳下跳下，是咯咯聲的源頭…各路英雄，有無試過，有冇得救？ [搞自閉]

見到七姊妹，便知秋冬來。

Finally, some photos to share taken under that clear sky at PTC on 8.8.2013. Canon 5DIII, CD-1, 800mm f/8 lens, ISO=4000, Single frame (46s for M8, 60s for Omega, 20s for Trifid). No stacking and filter cause I'm still learning them. Thanks to all pass-by, each one of you, sharing what you know with...

小時候聽另一個神級天文人談觀月蝕：下雨不走，起雲不走，全程鏡頭對準月亮位置，只要雲隙經過便是全港唯一一張月蝕照。原來神都是這樣出來的。

thx, just try but it failed. I shall try to take some picture at PTC tonight and try again.

If I took a night sky photos, any software could automatically identify stars and deep sky objects on it? Thx.
