又最大的月亮



二零零九年二月九日




為何每隔一頭半個月就有「XX年來最大的月亮」?到底月亮可以有多大呢?








看了幾個鐘頭,看不出「最大」。下面三張照片,請找出三個不同之處。

 20:49

 22:45

 02:17


三張照片只是拍攝時間不同。根本看不到甚麼半影月蝕,還是看電視精楚一點。

  3. All I can see is: 20:49 -- the brightest, 22:45 -- less bright (especially the "upper" region), 02:17 -- the least bright out of the three, which kinda make sense according to HK Observatory link:

    Figure 1 and 2 show the difference between different kinds of lunar eclipse.
    [版主回覆02/12/2009 01:12:00]我 諗 係因為用 唔同 嘅 光圈快門 ev 等等 咋,因為電視講嘅半影月蝕, 喺月亮表面會有一層層半透明陰影喎,不過我影唔到。

  4. David and I actually went out of our building to see the moon. We can see some shadows along 2/3 of the moon when looking at it with the naked eyes. However, the pictures that I took with my camera produced similar output as yours, Isis. The photos only showed a bright circle with no shadows within it. I wonder why???
    [版主回覆02/13/2009 00:38:00]因為我 哋部相機唔係長鏡頭, zoom 得太盡又會矇。上面三張相個月光本來好細,我裁 咗黑色部份先有咁大。
