Cropped and upscaled image of M43 (aka De Mairan's nebula) captured in narrowband.

While processing my annual rendition of M42 , I noticed the detail in M43 that I had not seen before. Perhaps it was the framing. After further processing, I decided to crop this beauty as a stand alone image. The brighter Trapezium to the right gives perspective. Captured from my backyard observatory under Bortle 6 skies.

With all the attention given to the M42, "The Great Orion Nebula", M43 is often overlooked. But this nebula is filled with amazing features that emerge through SHO narrowband filters.

Imaged over two brief moonless nights

Upscaled 2x using Topaz Gigapixel.

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.
