Lion Nebula (SH2-132)

The Lion Nebula, catalogued as Sharpless 132, in the constellation Cepheus, is an emission nebula around 10,000 ly away. It contains two ionizing Wolf Rayet stars and two dark nebulae (LDN 1150 & 1154).

This is my first mono project using the ASI294mm-Pro, processed in APP using the SHO palette (with modifications in PS). I've taken some time taking good calibration frames for each filter and gain setting (6 sets of Flat/Dark Flats and 2 sets of Darks) and I'm happy with the results from the initial integration. I'm still developing my processing workflow, including better ways to handle noise reduction and star control (using StarXTerminator). I have noticed the problem with the AI5 version of StarXTterminator introducing smooth, noise-free patches around stars and await the update for PS with AI6 which apparently solves this problem.

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.
