This tiny planetary nebula NGC2818 found nestled in the open cluster NGC2818A is often overlooked and rarely imaged. With an apparent size of only 0.8’, it presents a challenging target to image and process. Imaged with the Optolong L-Ultimate 3nm dual narrow band filter, and RGB stars. Channels extracted in APP and recombined and processed in PI. A very faint Oiii outer shell can also be noticed to the upper left of the PN. Integration was 15hrs of narrowband (120sec subs) and 3hrs RGB stars (30sec subs), full moon B7 backyard.
Although the PN is the star of the show, the open cluster which shares the FOV provides a beautiful accompaniment, and I've tried to bring these surrounding stars to greater prominence so that they provide slightly more than just a pretty backdrop.
