Revision title: Rework with new ABE settings.

M42 and M43 are amongst my favorite targets. I wanted to have a closer look at M43 with the TeleVue 2.5x Powermate assuming it would be bright enough. I combined the images with a couple of narrowband subs. The processing was done after removing the stars paying specific attention to the faint nebulas surrounding the main M42 and M43 parts.

Title: Rework with new ABE settings.

Description: While in the original version I completely avoided ABE at all (as I found it would cause a kind of greyish wash out in the outer regions of the image) I increased the tolerance for "local rejection" to 1.0. By this the "greyishness" was avoided and colormanagement was much easier. At the end this is a complete rework.

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.
