The E Nebula (Barnard 142 / 143)

Revision title: Partial re-edit, enhanced star colors

Barnard 142/143 is another dark nebula in constellation Aquila with a distance of about 2000 lj. I could find only a handful of images on astrobin so this object seems to be still a bit "exotic", although quite large (about full moon size) and not hard to image under dark skies.

As I am imaging from a light polluted place I had to go with many subframes of short exposure time. So this target, in terms of number of subframes, is my biggest project up to now. 1085 subframes (including flats) with the 61MP full frame camera added up to 132GB of raw data for processing. Number crunching in PI's WBPP took the most time, subsequent postprocessing was straightforward. As the object itself did not take up the whole FOV, I could crop generously.

Hope you enjoy this version of the object.

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.
