Crescent Nebula NGC6888 in H alpha
This is a retake of an image I captured exactly one year ago. This time, I turned the camera vertically for a more interesting view of the region.
My back yard; June 16, 2012, 10:30 PM - 3:30 AM; seeing and transparency average. Parsec 8300M with H-alpha filter on TV-85 at f/5.6; guided; 15x1000s exposures.
