Otsikko: Can cold kill my guide cam?
Kirjoitti: siovene - 18.02.2011, 08:19:30
Hi,
in the past few nights the temperature has been down to -25. I keep my astrogear in the storage room outside: it's closed, covered and dry but it's as cold as it is outside.

My guide cam, a QHY5 (aka ALccd5) won't work anymore: the led goes on but Windows complains that the USB device is malfunctioning. I have tried on 3 different computers, to no avail.

Could cold have killed it?
Thanks.

Hello,

Extreme changes in temperature or condensed moisture can kill CAM (or any similar electronic/optical device) I guess...

Then there hasn't been any change because the the camera has always been in outdoors temperature :)

Normally there are specified the working temperature and the storage temperature for every component. If they are not "mil" specified, the lover limits are higher than
-25C. So the ansver is yes, cold can kill your guiding camera. That don't mean that the camera is distroyed. That means that the manufacturer don't guarante anything.

  Hello 

It has been a lots of problem with QHY-5 USB-connection.
Many of amateur astronomies has told of the USB-failure.

  I hope you can work it out.
