What model SpectraStar do you have?
If you have an older instrument, it is possible to use a remote operations software to remotely connect to the instrument and operate the InfoStar software from a remote computer. It was designed and tested on Windows 7.
If you have a SpectraStar XT, it is possible to use an external computer to operate the instrument. Windows 7 or later is required. Please contact me directly if you would like more information.
