The Bridal Veil...
A long time ago, a big 'ol star near the Cygnus Constellation got very down-sized by collapsing in on itself. But things went too far, so much too far that it turned into a super-nova and the remains of that were discovered by William Herschel in 1784. This one goes by several names, the Cygnus Loop, the Filamentary Nebula, the Bridal Veil Nebula or just the Veil Nebula among other names. Then astronomers started giving names to the parts they could see and we have, today, three main named parts. The Western Veil Nebula, also known as the Witches Broom Nebula -- NGC 6960, the Eastern Veil Nebula -- NGC 6992 and some of the middle part called Pickering's Triangle also known as Fleming's Triangle. (Williamina Fleming discovered it and named it after the director of the observatory she used to find it. It does not have a NGC number because she discovered it after that catalog was published.)

This one is not too hard to find and see in telescopes in moderately dark skies. Just look for the Swan up in the sky and start from there.
This is the equivalent of a few moments more than 32 minutes of exposure.
