Lion Nebula Sh2-132 HaSHO

Wasn't sure what to expect from this object but poor seeing didn't seem to mess up the guiding too much. Over 5 hours usable data in a single session - shows how the night are drawing in at long last...

This processing attempt is ALL about the nebulosity to bring out that lion with scant regard to the stars!

I'll reprocess at some point to make the star-field more realistic but I can't spend all today in front of a computer!

Ha 10x 600s 1x1

OIII 11x 600s 1x1

SII 10x 600s 1x1

additional Ha 9x 600s 1x1

Description: Improved background treatment (gradients and colour) and less objectionable star halos whilst still seeing the much fainter OIII and SII reasonably well

Description: I collected some more Ha data for the Lion so there's now another 90 minutes of Ha. It was enough to make a decent luminance layer - so this is now a HaSHO image.
I think it will be a matter of personal taste whether this one is preferred to the more subtle versions but I think this one has more than enough pop to make a decent print.

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.
