Interesting Photos of Annular Partial Eclipse (日偏食)

Today, 22 July 2009, a central total solar eclipse is visible within a narrow path along eastern Asia, extending into the Pacific Ocean. Apart from the path of totality, a much wider range of areas can experience partial eclipse of different degrees. In Hong Kong, I saw an annular partial eclipse (日偏食) (max 3/4 sun coverage) in Hong Kong Science and Technology Parks (HKSTP) at 9:15am.

Since I have no special device, I tried to take some photos of the eclipse by placing a digital camera under a Myopia (short sight) Sunglass.

Sun was too bright, eclipse could not been observed in the photo.


However, it was interesting to find a small image of partial eclipse, near the sun, in my photo.




A small image of partial eclipse


It is because the sunglass is a diverging lens and it forms a small and gloomy virtual image of annular partial eclipse in front of the camera.

做實驗要不斷嘗試。當初只是用太陽近視眼鏡來做過濾,發覺不起作用。但我沒有立即放棄,再用Zoom In來看看,就照到影像 (因為對準了焦點)。雖然是僥倖,但可以用科學來解釋。現代很多科學發現都是從不停嘗試中找到的。

無equipment之下都影成咁,真係好勁呀!我中意第二張,太阳與月亮,男人大與女人小,有啲距離又貼得近...
