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).

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
