Cooling
Atik cameras are thermally stabilized to allow your CCD to output the best
result that it can deliver: please see the table in section 4 for details specific to
your camera model. After switching on the camera it is advisable to allow at
least 2 minutes before taking images, in order to allow the temperature to
stablilize. The very low readout noise, combined with efficient cooling, means
that dark frames are not necessary in most situations, allowing you to spend
more time imaging and less time taking calibration frames.
The Atik 314L+ has a regulated cooler that allows the selection of the desired
sensor temperature. Please refer to the Artemis Capture guide for reference
on how to set this up.

Replacing the desiccant
Your
camera
includes
molecular sieve desiccant tablet which is used to
avoid condensation in the CCD chamber. Although
this desiccant will last a long time it may eventually
need replacement or recharging, in which case
please follow the instructions below:
-
To
replace
desiccant port with the supplied plastic interface
and a screwdriver, take out the used tablet and
replace it with a fresh one. Replace the port cover and tighten (no need to
over- tighten). Wait 24 hours before connecting the camera again.
-
To recharge the desiccant, place the tablet in an electric oven at 200ºC
for a couple of hours. Take it from the oven, wait a few minutes for it to cool
down slightly, then put it back in the camera and wait 24 hours.
You will notice that there is a filter inside the desiccant chamber. The purpose
of this is to avoid contamination of the chamber when the desiccant is being
replaced. The filter is very fragile and should not be touched.
