Jewels of the Puppis - M46-M47 clusters and NGC 2438 planetary nebula

This picture showcases a mesmerizing array of astronomical objects in a relatively small field, in the constellation of Puppis. The open clusters M46 and M47 are the main subjects, complementing the scene with the planetary nebula NGC 2438 and the open clusters NGC 2423 and NGC 2425.M46: this open cluster is about 5,400 light-years away, with an apparent magnitude of 6.1; it spans an area of 27 arc minutes and contains about 500 stars, making it a relatively bright and large object.M47: located 1,600 light-years away, this cluster has an apparent magnitude of 4.2 and a brightest star of magnitude 5.7, making it visible with naked eye; it is a young cluster, estimated to be about 78 million years old.NGC 2438: this planetary nebula is approximately 2,900-3,000 light-years away, so it seems to be not physically linked to M46; it features a bright inner ring surrounded by a more extended and diffuse halo of gas, spanning over 4.5 light-years in diameter.NGC 2423 and NGC 2425 appear as relatively small clusters, since they are further than M46 and M47.

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.
