M42 - Orion Nebula

M42, the Orion Nebula, is probably the best-known nebula of all, since it is visible to the naked eye. It is a prominent part of the “sword of Orion”, beneath (south of) the 3 stars of the belt, and the whole sword is shown in this image. At about 1300 light-years away it is the closest region of massive star formation to the Earth.

This LRGB image is a work in progress. It consists of a set of 300 sec images during one night and is very clearly overexposed: the Trapezium region in the centre is totally saturated. The next step will be to use shorter exposures, probably 60 seconds. I also have some internal reflections from bright stars showing up as little triangles.

More work needed!

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.
