De Mairan's Nebula

This is, how close i can get with my equipment. I'm fascinated by this dense, dynamic and bright area of the Great Orion Nebula.

This nebula was discovered in the 1730es by the french geophysicist Jean-Jacques de Mairan, and catalogued by Charles Messier in the late 1760es as number 43, while the Great Orion Nebula got the 42 (of course long before Douglas Adams was born). Messier 43 is a star forming and HII region, which is separated by the "main nebula" by a dense barrier of dust. The glowing sphere of hydrogen measures approx 2 LJ in diameter, and is illuminated by variable star HD 37061 in 1300 LJ distance. It is located behind this dramatic scenery of dense dust, known as the M43 dark lane.

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.
