Hi Guylain,
I hope you are well.
Can you read the sensor temperature at any time you wish? Really I'm asking about reading the temp. while in a paused state, not directly after capture.
Here's why I ask: I'm envisioning a way to make capturing temperature matched darks easier. I do all my dark frames at some date after a night of captures, so I know the target temperature for my sensor. Currently i try to have the camera in an environment that matches the outdoor light frame temp. as closely as reasonable. But I still have to build a pause into the plan to allow sensor cool down. This is likely due to the lack of breeze and perhaps the camera on a covered porch so it can't radiate heat to the night sky etc. So I have to play with the pause length and so forth to get a good batch of temperature matched darks. I have to monitor the process until I get it working well each time.
What if I could capture dark frames based on sensor temperature? Set up the number of frames, ISO, exp length etc., and a target sensor temperature. If the sensor is too cold keep capturing frames with no pause. If the sensor never heats up to the target temp so be it, the process isn't successful. More often I think the sensor will become hotter than the target temperature (if the camera environment is rational) requiring a pause for cool down. Poll the sensor temp and when it gets to the target temperature trigger the next dark frame. This amounts to a variable pause length based on temperature. The temp rise during a capture should be fairly consistent for a given starting temp., hopefully yielding a nice set of darks with some throwaway frames from the beginning of the process.
Let's face it I'm getting spoiled and lazy. I'd like to set up a plan and go to bed, finding a nice set of temp matched darks in the morning. I've tried to avoid too much checking and automation in the description (thereby allowing failure if the sensor never gets hot enough for example). You already provided the extended delay time which has helped with waiting for the nighttime temps to drop low enough. The idea above could make a mundane task easier if implementation isn't too insane.
Thanks for taking the time to consider this one.
As always Best Regards,
Bob
