Nick Risinger, Seattle resident who created the amazing 5,000 megapixel photo of the entire night sky, will be the guest speaker at tonight’s meeting of the Seattle Astronomical Society. Risinger traveled 45,000 miles by air and 15,000 by land collecting the more than 37,000 individual images he stitched together to make the photo. He will talk about the experience and show some of his images. The meeting starts at 7:30 p.m. Wednesday, Sept. 21 in room A-102 of the Physics/Astronomy building on the University of Washington campus in Seattle.

Equinox sunset watch set for Friday
The fall equinox happens at just after two o’clock Friday morning Seattle time. Friday evening, Sept. 23, Alice Enevoldsen of Alice’s Astro Info will hold what has become a customary watch to observe the first sunset of the season. The Sun will set a bit before 7 p.m. Friday, so Enevoldsen and skywatchers will gather at Solstice Park in West Seattle around 6:30 to wait for the first sunset of autumn. (Official sunset is at 7:05 p.m. that day, but Enevoldsen has tweaked the time a bit based on local topography and conditions. She can do that, because she’s not only the author of Alice’s Astro Info, but the planetarium guru at the Pacific Science Center and a NASA Solar System Ambassador.)
Speaking of the Science Center, all exhibits re-open Saturday, Sept. 24 after the Center’s annual two-week closure for maintenance and installation of new exhibits. It’s not astronomy related, but the new Groovik’s Cube, part of Puzzle Palooza, looks like a lot of fun.
BPAA examines “A Star’s Life”
The Battle Point Astronomical Association hosts its monthly planetarium show Saturday, Sept. 24 beginning at 7:30 p.m. The topic of the presentation will be the life cycles of stars, from nebula to white dwarf or black hole. The program will be at the association’s John H. Rudolph Planetarium and Edwin E. Ritchie Observatory in Battle Point Park on Bainbridge Island. If it’s a clear night, club members will have telescopes on hand for observing, and the skies are decently dark at the site.
Comets at MOF
The Museum of Flight in Seattle devotes its Family Fun Workshops this weekend to comets and asteroids.
