強風で条件が全く良くありませんでした。
惑星像が、写野の中を飛び回っています。
それでも、瞬間を捕らえて観測できるのは、動画処理ならではです。

Here are some images of Venus from February 15, 2005, captured near the end
of evening twilight under fairly good seeing conditions. I think I detected
some subtle cloud patterns in visible light (with an IR blocker). Some of
these show up in the blue channel and also with a W47 filter, but not as
well.
