\nA bright candidate supernova remnant that was discovered in 2009 and somehow eluded detection previously! It measures approximately 5×3 arcminutes and its beautiful structure consists of a series of interlocking elongated and curved filaments with its southern rim being the brightest part. Long Ha and OIII exposures reveal a lot more detail and nebulosity in the surrounding area. OIII in particular reveals an impressive tail structure with a length of 8 arcminutes that extends to the left. The field of view also includes many emission nebulae to the south such as NGC 6857 and Sh2-100 and the planetary nebula IPHASX J195958.2+332939.
