NGC3199 - The Banana Nebula

NGC3199, commonly known as the Banana nebula, lies roughly 12,000 light years away from us in the southern constellation Carina. At its center lies an especially hot and luminous Wolf-Rayet star WR18. Wolf-Rayet stars are massive, hot, short-lived stars that generate an intense and complex stellar wind. This often leads to interestingly shaped neublae around them as is the case here.

Originally the brighter side was thought to be a bow shock as the star quickly moved through space. But studies have shown that the star is not moving fast enough to cause this and the likely cause is simply that there is more interstellar material to ionize on that side of the star.

There are not many award winning images on Astrobin for this object, and only a single top pick. A challenge! In addition to the 44 hour integration time, I spent a lot of effort on the fine filamentary structures while controlling the dynamic range of the bright area on order to try to make this a compelling image. I opted for a more natural dynamic pallet vs a straight up SHO. But, I left an SHO version in the revisons for comparison.

Thanks for checking it out.

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.
