The Lion Nebula SH2-132 in SHO

Sharpless 2-132 is a bright emission nebula in the constellation Cepheus and imaged in narrow band plus RGB for stars and depicted in the Hubble palette. It has good amounts of all 3 primary lines used in the Hubble Palette (Ha, SII and OIII). The nebula is approximately 20' x 30' in size, so presents a good target for many amateur astronomers. I imaged sh2-132 through a TEC140ED with astro-physics flattener mounted on an Astro-Physics 1100 GTO mount with encoders. The camera used is an ASI6200mm with Chroma RGG and Chroma 3nm narrowband filters. I imaged unguided using instead a custom DEC-ARC sky model. The exposures were 15 (Ha and SII) and 20 (OIII) minutes. The total imaging time including 1.5 hours per RGB filter is appoximately 24 hours. When processing I only emphasized the areas that keep a good view of 'the Lion' while there are other areas that could be brought out but end up making the Lion harder to recognize.

Description: Updated colors a bit to more generally used (cyan instead of deep blue). Brought out a little more in area around lions head, but not too much I hope. Fixed some pixelation due to an un-blurred mask.

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.
