M17 The Omega Nebula

Images taken by a QSI683-wsg8 camera with both HOS and RGB filters and a Takahashi FSQ-106 scope on a Paramount MyT from Deep Sky West's dark sky site in New Mexico. Processed with PixInsight 1.8.8-2. Sub-frames taken over numerous nights in 2019.

Narrow band data was processed in SHO combination. Nebula detail was brought forth with PixInsight UnsharpMask after applying mask created using new Starnet process which removes stars from selected image. NB image had nice nebula colors but had whitish mono-color stars. RGB data was then applied with PixelMath through a StarMask to give a somewhat more natural star palette.

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.
