Re: [MaxImDL] proper startup and shutdown of camera

With the talk about the shutters not closing on some camera's, I was wondering if I could get a rundown on the proper procedures for starting up and shutting down the camera. During startup do you just turn the cooler on and go? On shutdown do you just disconnect and close the program or do you turn the cooler off then do camera warm-up? My h18 is new to me and would like some feedback. Thanks.

Warming up a camera is usually done out of an abundance of caution. I've never

heard of a CCD camera being damaged by a temperature transient. That said, if

your camera is capable of very high delta-T, e.g. 60 degrees or more, I'd

definitely click the warm-up button and wait for the delta to drop to less than

20 degrees before powering down.



If your camera only does 20 degrees I wouldn't worry about it. Pull the plug.



If your camera does 40 degrees then I'd probably do the warm-up just to be

cautious. I think the H18 is in that category.

I didn't mention startup. Not a big deal. Turn on the camera, connect, and set

it to the target temperature. Wait for it to stabilize.



Once it's stabilized you should check that the cooler isn't pegged at 100%

power, because if it is the camera can't regulate. If it's pegged you'll need

to raise the setpoint.
