手元の温度計で−17℃でした。翌朝旭川では−19℃を下回り
ましたが、郊外の江丹別では−30.7℃でした。皆さん想像でき
ますか?
思ったより気流が安定していませんでした。光軸がまだずれて
いるのも悪いのですね。

Dear Friends,
Just recieved the Cooled ToUcam Prototype from my friend and attached is the first try I took with it.
Transparency was low (3/10) but surprisingly the image was clean even the shot was taken at >F40 (I shall
check the accurate focal ratio as the distance of CCD chip and Barlow is longer than before). Ambient
temperture is 13 degree C. Please see the attached image with original size.

I have compared the darkframes before and after switching on the cooled peltier (30 mins difference) and
the huge difference of the dark current.

Kind Regards,
[Eric Ng, Tai Po site Hong Kong, China]
