Formally NGC 6960, also known as the Western Veil, part of the Cygnus Loop, a huge old supernova remnant, currently 3 degrees across. This is only a small part of the whole. North is to the left, the bright star is 52 Cygni. Photographed with 2 hours each of nitrogen, hydrogen and oxygen narrow-band filters for a total of 6 hours over several nights at the back end of August.. A bit short time, but we've been clouded out lately, I doubt I'll get more data this season. The sky conditions were pretty dire too, with haze reducing the transparency and exacerbating the light pollution. Imaged with my 130mm f/7 apo triplet and 0.75x reducer and cooled CCD camera. The filters were 3nm bandwidth Astrodons The exposures were broken down into 10 min subs and stacked in AstroArt 5, a dedicated astro imaging program. The processing was long and involved to bring out the faint tendrils without either burning out the highlights or bringing up the background noise. More data would have helped enormously. The nitrogen (Technically [NII]) was assigned to red, hydrogen (HII), to green, and oxygen ([OIII]) to blue, similar to the familiar Hubble Space Telescope palette.
