Hi Folks,

Once again, the weather has stopped me from collecting new data, so I have done another Reprocessing Project!

This time, I went back two years to 8.3 hours of narrowband data I had collected for SH2-132 - better known as the Lion Nebula!

This is an impressive region of emission and dark nebulae and star clusters measuring more than one degree across. This is located 10,00 light-years away in the constellation of Cepheus.

The original image looks a little crude to me today, and I am much happier with my new version. It's fascinating what can be done with old data when leveraging new tools and techniques - along with some more experience under my belt.

For comparison, here is my original image:

You can see the new version above.

Hope you like the new version!

Clear Skies,
Pat

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.
