LMC #5 - The Open Star Cluster, NGC 1966, in N144 and environs (Large Magellanic Cloud region)

Lying between the Tarantula Nebula (NGC 2070) on the east, and the bright galactic cloud
of the LMC on the west lies this interesting field of open star clusters and emission nebulae. The
prominent nebula and star cluster houses the open star cluster, NGC 1966. It is only one of
the clusters identified within the nebula that are fuelling its bright emission. The nebula is also
referred to by this catalogue name, but is listed in Heine's Catalogue of LMC Emission Nebulae as
N144. It lies some 170,000 ly away, and at that distance lies within the LMC. The nebula is also
renowned for its O-III emissions, which in high resolution imaging take on the features of a rose.

The other nebula in this field are also fuelled by the radiation from embedded star clusters. It,
obviously, is a rich field for study.

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.
