Barnard 143 (with 142)

This object consists of two dark nebulae (B142 and B143) located 2000 light years away in the constellation of Aquila, about the apparent size of twice the diameter of our full moon. For obvious reasons, its nickname is Barnard's E Nebula. Its beauty is in its simplicity - just a few dark dust lanes in front of a dense star background.

Looking carefully, it is interesting to me how the dust extends and thins towards the bottom of the image. The "E" looks like the top of several dust columns which have been shaped by interstellar winds. Wider field of view images show that dust extends throughout the area, but is most concentrated in the "E".

The blue star colors throughout the image have been dimmed by the extensive dust field.

The refractors!

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.
