Temperature readings

[dkerber]

I don't know if this is an issue with BYE or with the camera itself, but when the actual temperature is about 5 def F (-15C), the camera temperature as shown in BYE still never goes below 0C, and usually hangs out at +3 or +4C. A few possibilities come to mind: the camera (Canon T3i / 600D) won't indicate below about -2C. Or maybe BYE won't interpret those lower temps. Any idea?

The temp is from inside the camera and the internal electronic will keep the body warmer inside.  

This said, the temperature reading comes directly from the image exif metadata, whatever is in there is what BYE will report on, and will have no problem displaying negative numbers if that is the true value.

Go to settings and enable the setting that produces the exif.txt file, look at the number in there, it should match was BYE displays.

There are three significant Temperature Readings related to AP Imaging:

1. Image Sensor Temp - necessary to match Darks to Light Exposures - recorded by Canon and Nikin DSLRs into EXIF Data and displayed by BYE/BYN
2. Ambient Temp - useful for Dew Heater Control - usually reported by a USB Device such as TemperHum (which BYE/BYN used to support)
3. Scope Body Temp - useful for Auto-Focus routines - usually reported by Focuser Device or External Sensor to ASCOM and displayed by BYE/BYN Premium Edition in the ASCOM Focuser Control

Ok, thanks Guylain.
