SH2-126 Ha

SH2-126 is a nebula with a large angular size but low surface brightness, located in the constellation Lizard. The shape of the nebula reminded me of the uppercase A. It is assumed that the nearby star 10 Lac in the center of the Lac OB1 association is responsible for the ionization of gas in SH2-126.

During image processing I discovered a specific arrow structure against the background of the nebula. Then I remembered that two years ago I was shooting dust nebulae against the background of SH2-126 in LRGB on ED80 and there was the same nebula shape (https://astrob.in/sfwyfh/0/). For fun, I superimposed the LBN437 image on the SH2-126 wide-angle image and got such an interesting image. This image demonstrates the difference in field of the ED80 B building with a wide-angle setup using a 135mm Jupiter 37A lens.

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.
