Roar! The Lion Nebula in Cepheus (Sh2-132)

The Sharpless Object Sh2-132 in the constellation Cepheus shows its "lion shape" rather in the outlines of the concise H-alpha emissions. This image dissolves when combining deep H-alpha and OIII data, revealing a complex structure of bright, excited gas emissions and dark nebulae.

The image shows two planetary nebulae in addition to the main object. The small, blue PN G101.5-00.6 at 4 o'clock and the larger PN G102.9-02.3 at 7 o'clock. Beyond that the somewhat inconspicuous open star cluster NGC 7726 can be seen, also in direction 4 o'clock.

The image was taken with a TSCF Apo 80/480 reduced to 384 mm focal length and an ASI 2600mm-pro

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.
