Additional Downloads:

  • The standard installation file for Eclipse Orchestrator ships with only about 70 satellite map tiles covering the most popular eclipse destinations, out of the over 11,000 tiles required to cover the Earth at full 500 meter per pixel resolution. If you have purchased the Pro version, you may download the full set of map tiles by clicking this link and following the instructions to download the 228 MB file.

Upgrading Versions:

Version History:

  • 2019 June 16: 3.8 release.
    • Add Canon EOS 6D Mark II, 77D, 250D, 200D II, 800D, 1500D, 2000D, 3000D, 4000D, 9000D, Rebel T7, Rebel T7i, Rebel SL2, Rebel SL3, Rebel T100 support. R, RP infrastructure included but not tested yet.
    • Add adjustable solar radius (Setup | Solar Radius menu). The traditional value of 959.63 arcseconds from 1891 is obsolete and may give poor predictions near the path edges. A new value of 959.98" is recommended per Jubier et al (2018). See also Meftah's (2018) 959.83" in green, 959.86" in orange, and Lamy's (2015) 959.99". This will change contact times by one second or more depending on proximity to the path edge. We recommend changing to 959.98" because it represents a more conservative totality duration and better matches Baily's Beads predictions. Arbitrary values can be entered in case future research improves it further. As always, bracket in time by several seconds around the expected second and third contact times in case of any number of possible problems.
