In a potential upgrade of what we currently have, we might consider going to linux and freeware, for our command system.
Some devices can be operated via the indiserver concept. Devices for which drivers have been written can be commanded from essentially the linux command line. This means that scripting systems are easier to set up - for us at least.
I have been able to control our SXV-H9 CCD camera using this system. Here is a link to how it is done:
There exist indiserver drivers for gphoto2 - that means that Canon DSLR cameras, for instance, can be operated in this way.
A TrueTech filterwheel is being tested. LX200 telescopes can be controlled - i.e. mounts such as ours.
