急に晴れてきたので急いで用意して撮像。
シーイングが悪くてIR-90では模様が出なかった。
U-340はエドモンドのものですがDR-655と合わせて使用。

weatherconditions were a mere better,but still some strong winds
made capturing difficult...

Here's my first attempt in using the Baader Ca filter (thanks for the loan!) to detect Venus clouds.
This filter (395nm,just 8nm bandpass) delivered a sharper and steadier live image than any else UV pass filter I used so far!
Same shutter and gain levels as before.
The contrast was a tad lower but this is can be fairly compensated by a larger UM or wavelet.
