Open Cluster NGC 3572 and the Southern Tadpoles

Despite its proximity to the Great Carina Nebula from our perspective, the open star cluster, NGC 3572,
lies only some 6,500ly away, putting it in the Carina-Sagittarius spiral arm of our Milky Way galaxy. (The
Great Carina Nebula, NGC 3372, lies some 8,500ly away.) The cluster (just below or south of the nebula)
contains hot, bright, young stars whose stellar winds sculpt the associated birth nebula into many
unusually shaped features, the most obvious being tadpole-like in appearance. The general shape of the
nebula, however, reminds me of a prawn!

This rather obvious nebula does not appear to have a standard catalogue entry. Its location in the
Carina-Sagittarius spiral arm is occasioned by much nebulosity, as can be seen here.

I have used a H+O triband filter in an effort to display the nebula’s features more clearly.

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.
