What Is Solar Eclipse Maestro?

Solar Eclipse Maestro is the most versatile and feature-rich application for solar eclipses and can be used as an automated solar eclipse photography freeware. Commercial distribution is strictly forbidden.
It can handle any solar eclipse, provide you Baily’s beads preview and animation, simulate an all-sky view or weather statistics, and a lot more. To help you enjoy the event, you can use it to control up to four USB or Firewire connected cameras (Nikon and Canon DSLRs or MILCs, plus Nikon Coolpix line and now a few Panasonic, Sony, Fuji and Olympus) during an eclipse so that you can be free to concentrate on observing the event visually. Up to four USB or Ethernet connected SBIG CCD cameras with filter wheels are supported as well. 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 eclipse events. All features are optional, so the application can be used for as little or as much as desired.

First developed for the 2008 total solar eclipse, it has been successfully tested in the chinese Gobi desert. For the total and annular eclipses of 2009 and 2010, and all the next ones as well, many users have reported it worked flawlessly for them. Others are even using it for other purposes such as shooting auroras time-lapses, triangulating sounding rockets, etc.

Mercury Venus Transit Maestro is a similar application meant for solar transits.
