M42 in Narrow Band SHO with RGB Stars

Revision title: Core with Stars

Messier 42 (M42), one of the most famous winter target for every astrophotographer, so called Orion Nebula, is an emission-reflection nebula located in the constellation Orion. With an apparent magnitude of 4.0, the Orion Nebula is one of the brightest nebulae in the sky and is visible to the naked eye. It lies at a distance of 1,344 light years from Earth and is the nearest stellar nursery to Earth. The nebula has the designation NGC 1976 in the New General Catalogue.

This image is a easy combination of my narrow band data of Panel 5, where in PixelMath R=SII, G=Ha, B=OIII and all stars are replaced with RGB one.

Note: This is not a result of linear combination as usual. Each channel is processed to non-linear status with SXT/ArcSin/GHS/HDR...etc. before combined in PixelMath.

Integration Info:
1.Ha : 26x300sec
2.Oiii: 16x180s+15x300sec
3.Sii : 34x300sec4.RGB: 3x30x60sec

Overall: About 12h. Dates: P5 Jan 1st, 19th / Feb 7/8/9/10

Location of Remote Observatory: Daocheng Obs, Sichuan,China

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.
