M43 De Mairan's Nebula

M43 De Mairan's Nebula
M43 is 1,600 light-years from Earth and has an apparent size of 20 x 15 arc minutes, which corresponds to
a spatial diameter of 9 light-years. Physically, M43 is a part of the Orion Nebula and both M42 and M43
are part of the much larger Orion Molecular Cloud Complex. M43 was discovered by Jean-Jacques
Dortous de Mairan sometime before 1731.

Note: While I was imaging M42 I zoomed in on the image (live stacking). I was surprised
how much detail M43 had, so I made that my target. I tried to get the trapezium so I
also took 140 x 3 second exposures and processed that separately, and layered both
final images together. Note: The Orange color was pretty much what I was getting on
the 6200MC so I didn't do much with the final color except boosting the red on
midtones.

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.
