I would like to have the option of automatically warming up the camera at the end of a session. It maybe doable with scripts, but it could be easier if Demetra itself could do it directly.

I normally sit by the telescope, or from a nearby room, when using LISA with my telescope. But sometimes i am pointing at a faint object that may require several hours of imaging.
In that case, i take the calibration images, then start guiding and imaging the object. Then i could go to sleep as i can programm the telescope to stop and the roof to close, but i would also like Demetra to warm up the camera at the end. I can programm the camera to be switched off direcly, but i think a warm up is healthier.
Also, i could programm Demetra to exit and use another programm as CCDSoft or Artemis for the warm up, but doing it directly with Demetra would be easier and even more elegant.

Hello David,
This is an interesting question, that have already been discussed some time ago (not on this forum, I think).

Demetra controls the cameras through the ASCOM platform, which makes a universal interface between any camera and any software.

In this context, this is the responsibility of the Camera manufacturer (potentially through its ASCOM driver) to manage warm-up of the camera if this is required (he is the only who knows if this is required or not). If we would add a "warmup" feature in Demetra, how can we define what time we should take, what temperature steps, and so on (it would be dependant on each camera I guess).

Do you see what I mean ?
