LMC #8 - Complex N51 & Open Clusters NGC 1955, NGC 1968 & NGC 1974 (Large Magellanic Cloud)

Due north of the LMC’s main galactic bar lies the region designated N51 in Heize's Catalogue
of the LMC Emission Nebulae. It comprises both emission and reflection nebulae, and a
“superbubble”. The superbubble (lower right) is an area that has been sculpted clear of much
of its gas and dust by the pressure of the coronial ejections from the very active stars embedded
within it. Here, the open star cluster, NGC 1955, is presently performing this task.

Moving along the emission nebulosity extending towards the north-east, we encounter the
bright open cluster, NGC 1968, and its lesser cousin, NGC 1974. At the upper left corner is
found NGC 2004, another open star cluster but with a well-defined core, or central compaction
of stars.

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.
