M42, M43 and the Running Man

M42 and M43 are defuse nebulae of the Milky Way in the constellation of Orion. They are about 1340 light years distant, on the near edge of the Orion Molecular Cloud Complex.

M42 (NGC1976) was discovered in 1610 by Nicolas Peiresc. It was recorded by Charles Messier as M42 in 1796.

M43 (NGC1982) was first noted in 1731 by Jean-Jacques Mairan. It was also recorded by Charles Messier in 1796.

The blue reflection Running Man Nebula (NGC1973 + NGC1975 + NGC1977, or Sharpless 279) was names about 20 years ago.

Revision A combined 5sec, 30sec and 120sec exposures with Adam Block's"missing data" technique in CCDStack.

Revision B used NIK Filters HDR Efex Pro2 to combine the same exposures.

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.
