Observatory:…. Deep Sky West, Chile

EXPOSURES:

…S.….11 x 1800

Total exposure   25.5 hours

Image Width: arc-minutes
Processed by Alex Woronow (2021) using PixInsight, Topaz, SWT

The bright emission nebula in the center of this image is NGC 3503, the rest of the image is part of the greater Carina Nebula of the S. hemisphere. Other than studies of its molecular composition and distribution, not much has been written about NGC 3503. It is, of course, an active star-forming region, with the cluster that illuminates the clouds named PIS-17. Not a household name!

My processing involved mapping the narrowband filters to a reasonable representation of their true colors, removing the stars (using StarNet2), and invoking Topaz Studio2 to refine the structures and colors. The stars were copied back in using a simple PixelMath equation.

Comments and suggestions are welcomed.

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.
