IPHASX J200018+365934 also known as NeVe 2, is a planetary nebula candidate in the heart of Cygnus. The brilliant star that made processing this a nightmare is 25 Cygni, a B3IV 5th magnitude star. The image is so star-filled I couldn't get it below 1 meg in size. Finding the planetary candidate is almost a "Where's Waldo" challenge. Fortunately it is 30" in size and not star-like. I see no central star but the blue disk with a red outer ring is sometimes seen in planetaries. It's hard to see it as anything else to my eye.
This one was brought up last July by a forum post asking what it was? Once I figured it out I added it to my short list of objects. Like most nights last summer neither seeing or transparency were very good but it was registering so I just gave it double my standard exposure time to make up for the horrid transparency. The first reference to it as a possible planetary nebula was in the Strasbourg-ESO Catalogue of Galactic Planetary Nebulae Strasbourg-ESO Catalogue of Galactic Planetary Nebulae in 1992. Then again in 2009 in this paper: http://adsabs.harvard.edu/abs/2009A%26A...504..291V . Apparently no definite answer to its nature is known as yet. It's one of several hundred such nebula. An imaging task I doubt I'll undertake, I have too many on the to-do list as it is.

No way I could include the full image. Even at very low compression the 22000 stars in the image caused its size to be 7.5 times bandwidth limits. I cropped it to 433 pixels on a side (enlarged to 0.67" per pixel and compressed so where the colors are virtually gone in the stars to get it to fit the 140k limit. Sorry for the poor quality. Wish you could see the full image with 22,000 stars.
