Just a note to say that I finished an updated version.
It now works with all current Starlight USB cameras.
The big difference is that if more than one Starlight camera is attached, you get to choose which one will be used. That has the benefit that multiple instances of SXcon can be run to control up to 4 different cameras simultaneously.
Additionally, the configuration file changes mean you can have up to 4 alternate observing sites/gear setups. These are used to document the images better via the FITS header keywords (pixel size, long/lat, focal length etc).
Also, I improved the code internally to make it more robust to dodgy USB cables.
As before, anyone who wants to try the freeware code is welcome. Just email me.
