NIGHT OVER ONTARIO

LDN 1251 Dark Nebula...NASA APOD , September 30,2016

NASA Astronomy Picture of the Day, September 30, 2016. http://apod.nasa.gov/apod/ap160930.html Stars are forming in Lynds Dark Nebula (LDN) 1251. About 1,000 light-years away, the dusty molecular cloud is part of a complex of dark nebulae mapped toward the Cepheus flare region, drifting above the plane of our Milky Way galaxy. Across the spectrum, astronomical explorations of the obscuring interstellar clouds reveal energetic shocks and outflows associated with newborn stars, including the telltale reddish glow from scattered Herbig-Haro objects seen in this sharp image. Distant background galaxies also lurk on the scene, visually buried behind the dusty expanse. The deep telescopic field of view spans about two full moons on the sky, or 17 light-years at the estimated distance of LDN 1251 I am grateful to Scott Rosen who introduced me to this nebula and the tricks of the trade he so freely shared in helping to bring out the "faint stuff". The image was taken by Lynn Hilborn from Grafton, Ontario over 4 nights September 2 through September 4, 2016. It totals 16 hours of exposure with 10 minute frames at ISO 3200 with a Canon 6d and Teleskop Service Photoline 130 @ f5.6
