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.

好嘢喎！你真係同太陽有緣！
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...
