|Browse Lunar Eclipse Maestro Help||Notes|
Eclipse circumstances are calculated using the Besselian elements from Fred Espenak and Jean Meeus’s NASA Five Millennium Catalog of Lunar Eclipses. Formulas are primarily from Jean Meeus’ books Elements of Lunar Eclipses and Astronomical Algorithms.
To reduce the CPU activity and give as much time as possible to the process taking pictures while maximizing the autonomy of your laptop, you can turn off or lower the update frequency of the Moon-Earth’s umbra/penumbra diagram and eclipse map animations. When a script is running you can also lower the refresh rate for the countdowns. All this can be done using the contextual menus.
GPS Units and Timing
If you connect a GPS to use it as a timing source, make sure the GPS is reliable enough as a time standard. Run the GPS for a few minutes and then observe the rightmost value on the first line of the main screen (it’s in parentheses, a bit to the right of ClkErr). This is the standard deviation of the GPS timing measurements in seconds. If this number is small (less than 0.1s) your GPS is stable enough. If this number is large, something is wrong with the GPS and it cannot be used. Sometimes a GPS unit will give poor timing results when its display screen is set to a graphically intensive page, so try various GPS display pages to see which gives the most stable timing, leaving it on each page for 1-2 minutes.
