The Lion Nebula revist: 3 panels mosaic
Sharpless 132, is an emission nebula in the constellation Cepheus and lies some 10000 light years away in the Arm of Perseus along our Milky Way. The stars responsible for ionizing its gases are very hot and massive.
Integrated, processed and mosaiced in Astro Pixel Processor, post processed in Pixinsight and touched up in Paintshop pro for clarity and vibrancy. Total of 4.5 hours of data, span over 2 nights:
24 x 240sec light subs per panel (L Extreme filter)
30 x 240sec darks
30 dark flats
30 auto flats
Note: not used to hitting saturation this high, but couldn't resist to see the Lion head come out more

Equipment used: SW ED100 esprit Triplet Apo on HEQ5 Pro mount with ZWO 294MC Pro main cam and ZWO 120mini guidecam, 60mm guidescope, ASI Air plus, Optolong L enhance & L extreme filters, ZWO EAF, Bathinov mask, dew heater straps and powered by two Jackery packs. This is the Stars De-emphasized Hybrid HOO version using newly acquired scripts and tricks.

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.
