M 17 - Omega Nebula

Illuminated by ultraviolet radiation from young, massive stars on the right side of this photograph, M17, also known as the Omega Nebula or Swan Nebula, is one of the largest star-forming regions in the Milky Way galaxy.

M17 contains one of our galaxy’s youngest star clusters, at only 1 million years old. However, many of the young stars in this cluster are impossible to see because of the gas and dust that surrounds them. The powerful radiation from the young stars evaporates and erodes the dense clouds of cold gas in which new stars form. One such pocket of gas is seen at the center of the brightest region of the nebula and is about 10 times larger than our solar system.

Preprocessing in PI:
- WBPP for calibration and cosmetization
- SubframeSelector to find best image by PSF signal
- StarAlignment
- LocalNormalization using best image by PSF signal as reference
- ImageIntegration

Processing in PI:
- DynamicCrop
- DBE
- NoiseXterminator on Ha, Oiii, and Sii
- LinearFit Oiii and Sii using Ha as reference
- EZ soft stretch
- PixelMath to combine into Foraxx SHO

Postprocessing in PI:
- LRGBCombination using Ha as luminance
- TGVDenoise
- ACDNR
- StarXterminator
- MLT to slightly sharpen image
- LocalHistogramEqualization with RangeSelection masks
- CurvesTransformation
- DarkStructureEnhance
- PixelMath to add stars back
- EZ star reducuction

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.
