Simeis 147 / Sh2-240 is a very large supernova remnant (3 degrees in apparent diameter) that I captured here with various filters, a monochrome camera, and a camera lens with a focal length of 200mm. Very challenging and also very fun object to try with a wide field setup like mine. It was all shot from my light polluted backyard in Newark, DE. Tone mapped following J-P Metsavainio's procedure. The OIII signal was stronger than I thought, but tricky to incorporate. Resolution: 5400x4088.
