LBN438 - Eerie glow in Lacerta

LBN438 is a very faint dark nebula in the Lacerta constellation, which means lizard in Latin. It has a surface magnitude of only 22 making this a challenging object to image well. It is surrounded by very faint Ha emission which produces the red glow visible in the image. Not much is known about the mechanisms that cause this type of faint glow. It is referred to by multiple sources as ERE or Extended Red Emission. There is much debate in the scientific community about what exactly causes it.

To resolve these features requires very dark skies and a lot of integration time. I captured nearly 80 hours of data and only used the best 40 hours. There are a lot of cool an very distant galaxies visible in the background if you zoom in. Most of them are hundreds of millions light years away from us. It is always facilitating to consider that we are looking so far back in back in time when viewing these distant galaxies.

I hope you like it.

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.
