My first attempt at the Heart Nebula (IC1805). I've rapidly discovered that attempting to image emission nebula with a one shot colour camera is a challenging business, requiring relatively long exposures and dark skies. This was my second automated image, captured by ACP Expert over several weeks when the sky was clear, the moon was down and the Heart was above my local horizon. LIGHTS: 45 x 600s; DARKS: 30; BIAS:100; FLATS: 40 all at -20C. Post processing in CCDstack2+ and Photoshop CC.
