Featured Photograph

Messier 42, Orion Nebulah

Messier 42, the magnificent Orion Nebula, a favorite object in any amateur telescope, is usually portrayed in vivid, high contrast colors. While that looks spectacular, the reality is that one of our closest stellar nursery’s true colors are likely much more subdued. I have attempted to depict it in hues one might expect as seen in a large aperture telescope, showing the light pink emission regions and the bluish reflection veils surrounding the nebula’s core.

DETAILS: Astro Physics AP 155 Starfire shooting at f/5.2, though an IDAS LPS-V4 filter and a spectrally modified Canon EOS 6D Mrk II. Total exposure: 8 minutes at ISO 4000.

Monthly Meeting for March

Saturday, March 15, 2025
Presenter: Dr. Danielle Adams - Flagstaff Dark Skies Coalition

Title: “25 Years of Advocacy for Flagstaff's Dark Skies”

Description: In this 25th anniversary year of FDSC, Danielle will explore the legacy and impact of dark skies in Flagstaff, going back to 1892, when it was called "Skylight City", and the ongoing work today of the Flagstaff Dark Skies Coalition to nurture and celebrate our dark-sky ethos as a model for other communities to replicate. Danielle will also give CAS a preview of FDSC's plans for Flagstaff's International Dark Sky Week Celebration, April 19–27

Bio: Dr. Danielle Adams is a cultural astronomer and dark sky advocate who studies indigenous Arabian astronomy through pre-Islamic poetry and Arabic historical literature. She is active in informal astronomy education, speaking to various groups about Arabian cultural astronomy and the heritage of the many Arabic star names that astronomers still use today. Danielle serves as the interim executive director for the Flagstaff Dark Skies Coalition and uses the inspiration of pristine desert skies to advocate for the modern-day preservation of dark skies.
