Youtube video of the solar eclipse (click here)

Post to [digital_astro]
I live in the San Francisco Bay Area and was too lazy to go to North for watching the true annular eclipse. Well, I tried to do something unique. This Youtube video shows what I did. In this eclipse, a rather rare occurrence in our area is that the end of the eclipse turns into an Earth event, Sunset. I tried to come up with a video that shows two events continuously. 1~2 degree view angle is fine with the eclipse and probably at least 10~20 degree is preferable for the Sunset. I tried to make the transition. So, this video covers two events, the peak of the eclipse and the Sunset with the landscape.

My telephoto camera lens is Sigma zoom of 150-500mm. At 1000mm FL with 2x extender, the eclipse was photographed (ISO100 and 1/200 second exposure). When the trees started shadowing the Sun, the solar filter (Astrozap) was removed, FL was gradually reduced, shutter speed was adjusted. The extender was removed at some point and the F-value was increased too. Note I cannot adjust F-value with the 2X extender. I wish I had a pro’s TV camera, probably costing more than 100 k dollars.

Camera: Canon EOS T1i used at 10 second interval, creating nearly thousand jpg files.
Mount: Sirius EQ-G

日食当日は、サンフランシスコ近郊のこの辺り、全天雲ひとつないカリフォルニアの空となった。
日食とサンセットを１つのストーリーにまとめようと構想。以下のＹｏｕｔｕｂｅビデオの最後の３秒がそれ。

シグマズームと２Ｘエクステンダーで３００ｍｍ−１０００ｍｍの可変焦点、カメラはＥＯＳ　ＫＩＳＳ　Ｘ３を使用、Ｂａａｄｅｒ　Ｓｏｌａｒ　Ｆｉｌｔｅｒ装着で、ＩＳＯー１００、１/２００秒から、サンセット直後にＦｉｌｔｅｒを取り、露出を１/４０００秒から１/４０秒に連続的に上げ、焦点距離を　１０００ｍｍから１５０ｍｍまで連続下降（写真参照）。写真２と３はお隣の芝生に写った日食の影と車のドアーに写したピンホール写真。人間の目がすばらしのを実感。
