GUM 37 / RCW 54c in the Carina Nebula region - Home of the Southern Tadpoles (George Yendrey)

GUM 37 / RCW 54c in the Carina Nebula region - Home of the Southern Tadpoles

Gum 37 / RCW 54c is a diffuse HII emission region with the adjacent star cluster NGC 3572 in the Southern Hemisphere. Situated in the southern constellation of Carina this is region that is often overlooked due to the presence of the more popular and brighter Statue of Liberty nebula. Gum 37 contains the “Southern Tadpoles” adjacent to NGC 3572. Typical of many of the southern hemisphere gems there is limited information on this deep sky object. NGC 3572 spans 100 light-years across and is 9,000 light-years away.

This is a Telescope Live dataset with their new QHY600M full frame CMOS cameras - in this case mounted on a PlaneWave CDK-24 telescope Located at the El Sauce Observatory in Chile.

Approximately 5 hrs total integration (10x600s each on Astrodon 3nm Ha, Sii, and Oiii) filters, so not a very deep look at this object, but the Telescop.Live CMOS cameras have been installed only in the month previous, so I expect this dataset to grow over time.

This is a SHO palette; I considered an HOO or HSO, but the red of Ha just dominated the image while SHO gave some needed variance/nuance.

I reworked the color a bit to shift to more blue and less cyan(ish) tone to the nebula. I think this looks a better to the eye. I did do a complete reprocess.

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.
