Mercury Venus Transit Maestro is the most versatile and feature-rich application for Mercury and Venus transits. It can handle any solar transit over six millennium, and a lot more. To help you enjoy the event, it can control up to four USB or Firewire connected cameras (Nikon and Canon DSLRs, plus Nikon Coolpix line) and up to four USB or Ethernet connected SBIG CCD cameras with their filter wheels during a Mercury or Venus solar transit, so that you can be free to concentrate on observing the event visually. You must then preprogram all exposure information according to a script. Observer position (latitude and longitude coordinates, altitude) is used to calculate local circumstances, so that camera actions can be referenced to specific transit events. All features are optional, so the software can be used for as little or as much as desired.
