M42 (Orion Nebula) [Narrowband, Hubble Palette]

This image of the Orion Nebula was formed by blending narrowband (Ha, OIII, and SII) data using the Hubble palette. RGB image data was also used for most stars.

The Orion Nebula, also known as M42 and NGC1976, is a very bright diffuse nebula about 1,300 light-years from Earth and can be seen with the naked eye in the constellation of Orion. Four notable stars, known collectively as the ‘Trapezium’ can be seen in the brightest part of the nebula. Also shown is M43, also known as De Mairan’s Nebula, and the NGC1980 star cluster.

Total narrowband integration: 10.1 hours. Other RGB-only and RGB/NB blended images have also been prepared. To avoid duplicated Astrobin database entries, only narrowband acquisition details have been entered for this image. Nevertheless, the RGB details used for the stars are provided in text format below this description.

There is a very large difference between the brightest and dimmest parts of this nebula, making image processing a bit more complex to simultaneously show all/most elements.

The image was fully processed in PixInsight. The finalized picture was re-sampled by 120% for aesthetic reasons.

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.
