M46 is a pretty open cluster in the constellation Puppis. Planetary nebula NGC 2438 really adds interest to the field. Processing was straightforward - DDP in IP and some minor tweeks in PS. The nebula signal was quite strong and took a mild unsharp masking without any fuss. A fairly large bloom from mag. 4.98 star SAO 153227 was a bit of a challenge.
