I'm very new to all this - Raspberry Pi, Astroberry and Astrophotography, but having some fun. I was playing around last night, trying to get some images captured using CCD Ciel - as I could not get Ekos to download any images from my Altair GPCam2. CCD Ciel worked fine, and it was storing images in /tmp as per the default. However, when I started it up this morning, the files have all gone from /tmp. Is this part of a shutdown script or garbage collection? It was a useful exercise anyway I guess. No idea if this is OS behaviour or CCD Ciel.
Actually a quick test shows that all files in /tmp appear to be cleared out - so having /tmp as the default for ccd ceil is a bad idea!
This is standard behavior of linux systems.
I'm not sure where /tmp default location for captured images comes from. For sure it was not set to this location in Astroberry for the obvious reason (see above).
Maybe CCDCiel uses such a default? I would be surprised but everything is possible. I have checked it on my Astroberry and the directory is set to /home/astroberry
