   眼視で220倍も掛けられないような悪いシーングで、
176倍に下げて大赤斑が見えるようになりました。
これだけシーングが悪いとピントが上手くあっているのか
不安です。日の出まで時間があったのですが、シーングが
回復しそうにないので、撮影を諦めてしまいました。

I made an observation of Jupiter under average seeing conditions (4-5/10)
which revealed a good amount of detail over the jovian disk.
The detail observed will be noted below.
A very interesting and captivating sight was a double transit of Callisto and Ganymede over the northern hemisphere of Jupiter.
Two dark shadows were noted floating across the North Tropical Zone (NTrZ) and North Polar Region (NPR).
I welcome any comments you may have on my observation.
