The Lion Nebula (Sh2-132)

Image of the Lion Nebula (Sh2-132) taken on the nights of November 19/20/21/22, 2022.

Imaged with a William Optics GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer, Optolong L-Enhance dual narrowband filter, and modified Nikon D5300 DSLR. Total integration time of ~11 hours: 109 subs at ISO400 with an exposure time of 360 sec.

Pre-processed using Pixinsight's weighted batch pre-processing script (WBPP) to perform calibration, debayering, registration, local normalization, integration, and drizzle integration. Separated H-alpha (red channel) and OIII (average of green and blue channels) data and post-processed in Pixinsight: background removal using GradXpert, blur x terminator, noise x terminator, masked stretch, curves transformation, HDR transformation using EasyHDR script, and local histogram normalization. Final HOO pallette image generated using SHO-AIP script using luminance image image generated from blend of Ha and OIII data.

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.
