Hello everyone, we are building a telescope experiment to put in the stratosphere with the aid of a stratospheric balloon and we have this two cameras for use, one will be our main camera (ZWO ASI183MM) and another to use as a star tracker (ZWO ASI290 Mini). I would like to know if anyone has used them in low pressure (about 45 mBar) and low temperature (-20 to -50 Celsius) and if there's something that we should consider for this!
Thanks a lot for your help!
