SH2-132, Lion Nebula

SH2-132, also known as the Lion Nebula, is an emission nebula straddling the boundary between the Cepheus and Lacerta constellations. The nebula's vibrant display is likely attributed to the presence of two Wolf-Rayet stars, namely HD211564 and HD211853 (referred to as WR153). Remarkably, each of these stars contributes its own distinct hue to the nebulous expanse when observed through narrowband imaging techniques.

In the HOO-processed rendition (the second image), the contrast becomes especially pronounced. The nebulous region linked with HD211564 unveils a teal shade, signifying the presence of Oxygen III. Meanwhile, the nebulosity associated with WR153 and other colossal stars comes alive in red, representative of Hydrogen-alpha emissions.

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.
