LBN 440 (Gary Imm)

Celestial hemisphere: Northern · Constellation: Lacerta (Lac)

LBN 440

I saw this interesting obscure structure during my imaging of LBN 438. It is a very faint nebula located in the constellation of Lacerta at a declination of +37 degrees. Like most faint nebula, we do not have a good distance estimate for it. This magnitude 18 nebula has a surface brightness of only 23. It is 10 arc-minutes long. This object is the 440th entry in the Lynds Catalogue of Bright Nebulae.

This is not a spectacular nebula but I think its shape is interesting. I would like to know how such a “3-sided” structure could be formed. But, like many of the mysteries we uncover in these images, I likely will never know. It is probably the result of dust clouds being subjected to stellar winds over long periods of time.

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.
