Perigee Total Lunar Eclipse
Posted: 28 September 2015
Saturday, 26 September 2015, I and several other members of the Oracle Dark Skies Committee provided a "dark skies" information booth at the re-opening dedication of American Flag Ranch in Oracle. We gave a "No Light Pollution" pin to people who made a $5 (or more) donation to help support the ongoing work of the Committee. The observatory was not opened Saturday night.
A few clouds appeared mid-day on Sunday, 27 September. I did open the observatory for the Perigee (or SuperMoon, if you prefer) Total Lunar Eclipse. Here's an excellent article on "Sunday Night: Getting Ready For a ‘Super-Harvest-Blood-Moon Total Lunar Eclipse’" at Universe Today. The eclipse was in progress as the Moon rose at Cassiopeia Observatory.
Open: Sunday, 27 September 2015, 1808 MST
Conditions: Mostly clear
After opening the observatory I immediately began setting up to photograph the Total Lunar Eclipse. Added the f/6.3 focal reducer to the 8" LX200-ACF in order to capture the entire lunar disk with the D7200 DSLR. 1823 MST: viewed Saturn, 53X. Mounted the DSLR at prime focus + focal reducer + extension + visual back. Focused using Saturn. 1836 MST: slewed to the Moon's position (behind the hill to the east) and began waiting for the Moon to rise over the hill. 1855 MST: I noted that normally a Full Moon rising would have brightened the eastern sky by this time, but the sky was still dark. 1900 MST: the eclipsed Moon began to appear. Through mid-eclipse the Moon was visible through a tree. It did not rise above the tree until 2003 MST. At various times during the eclipse I viewed the eclipsed Moon using my 12x70 binoculars. What follows are unedited (except for the conversion from Raw to JPEG) photos of the "SuperMoon Total Lunar Eclipse" as seen from Cassiopeia Observatory.
