The image below is a new planetary nebula discovered by the INT/WFC Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS). It is a two-colour image, red for H-alpha and green for [OIII], and it has been obtained using the Wide-Field Camera on the Isaac Newton Telescope. North is to the right and East is to the top. The exposure times amounted 50 minutes in H-alpha and 30 minutes in [OIII]. The nebula was confirmed to be a relatively old planetary nebula using the ISIS spectrograph on the William Herschel Telescope. Credit: Laurence Sabin, Nick Wright and the IPHAS Collaboration.
