Filter wheel support
Since version 2.1 FireCapture supports direct ASCOM filterwheel support but the old build-in script interface is still available. Lars Zielke and Wei Leong Tan both implemented an ASCOM interface for the previous FireCapture versions. Even these old interfaces are obsolete since 2.1 you can still download them here but for problems and questions regarding these interfaces you need to contact the guys directly.
