The elephant's trunk nebula - IC 1396 (HSO). A series of 400-500 second exposures were taken over four nights, about 25% through the HA filter and the other 75% from the O3 and S2 filters. Total exposure time was about 8 hours. Taken under moderately light polluted skies (suburban) in my back yard in Woodinville, WA.
