Summary0002927: Camera cooling not fully stopped
DescriptionHello,

when selecting camera warmup as termination command of a planned sequence, CCDCiel just sets the target temperature to 20°C. This is in summer not ideal, since the ambient temperature can go higher. This leads to continued cooling at the end of the session (or during daytime, if CCDCiel not terminated until then).

I see the following as possible solutions:
- Set target temperature to really high values (e.g. 60°C)
- Disable cooling instead of increasing target temperature


Thank you

I do it this way to be safe and almost sure it work with all the camera and drivers.
The Ascom documentation warn again brutally setting the cooler off and also explain that a driver can reject a too high temperature.
Setting it to 20 has proven to work for the last ten years.

But you can use the CCDciel scripting capability to set another temperature if your camera accept it.
Create a new script with the following content:
from ccdciel import ccdciel
ccdciel('Ccd_settemperature',60)

Then select to run this script in the sequence termination options.
