I didn't think about it until this thread.
Guide 7/8 -field maps
MaximDL3 -capture/guideing/focus/blink/process images
Astrometrica -Asteroid search & astrometry
Paint -convert to .jpeg
Jasc Animation -Asteroid animation
Meade Autostar suite -operate 200mm finder camera
Vspec -spectral analysis
Astromist -star maps on iPAQ
Argonavis -pointing
Seems a lot but they all get a workout depending what my fancy is at the time.
