M46 and M47 with a hidden nebula!

Messier 46 and Messier 47 are 2 open clusters in the constellation Puppis, they’re only about 1 degree apart so they’re usually imaged together. Less famous than the “Double Cluster” in Perseus, M46 and M47 are still very interesting mostly because of what’s “hidden” within M46, a small and bright planetary nebula NGC 2438. The nebula is likely not related to the cluster but just appears to be inside it from our point of view. If you’ve got a big telescope, try imaging the nebula for a full night, it’s actually pretty cool as it has a bunch of HA expelling from it (like the Ring Nebula in very long HA exposures).
Shot with the QHY600C and SVX130!
