| Summary | 0002927: Camera cooling not fully stopped | ||||
| Description | Hello, 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. |

I make a change to stop the cooler, but this can work only when the temperature ramp is activated because in this case it monitor the temperature and cooler power. If not already in used, check "Limit temperature change" in Preferences / Camera, and set a reasonable allowed change to not slow the cooling too much, maybe 5 or 10. Now when the temperature is set to exactly 20C, as at the end of a sequence, the cooler is stopped when this temperature is reached or when the cooler power is null. To test, Install the version 0.9.96-4184 from https://vega.ap-i.net/pub/ccdciel/daily_build/ It worked for me last night. |
