The Whirling Dervish & Banana Nebulae (NGC 3247 & NGC 3199)

Immediately to the north north west of the Great Carina Nebula (NGC 3372) lies this pair of emission
nebulae and their associated open star clusters. They are members of the very large Carina molecular
cloud complex, designated Sodroski 62. Both are H-II regions indicating that the gas cloud is being
irradiated by high energy UV light from hot, young stars.

NGC 3247 is also catalogued as GUM 29 and RCW 49. It’s common name derives from its likeness to a
whirling dervish, as seen from above. It lies some 13,700ly away, and is estimated at 300-400ly across.
It contains over 2,200 stars, at least 200 of which have dust disks. This is considered a star forming
region and is one of the brightest H-II regions in our galaxy.

The common name for NGC 3199 is an obvious assoication. James Dunlop first observed it in 1826. Its
distinctive shape was originally thought to be a bow shock-wave, but recent studies have discounted this.
It hosts one of the fairly rare Wolf-Rayet stars, WR 18.

I have imaged this with a H+O tri-band filter to display the nebulae’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.
