Totality 2017 Revisited

When I observed the total solar eclipse in 2017, I was essentially brand new to image processing, and I was a complete novice with Adobe Photoshop. After a few months of fiddling, I ended up with an image I've been very pleased with.

In anticipation of the eclipse on April 8th, I wanted to do a completely fresh re-process of my 2017 data to practice what I'll do if I'm fortunate enough to capture a similar dataset this time. I have to say that I am blown away to see how much I've learned about image processing in 6+ years! The thing that stood out the most in my memory of the eclipse was the 3 long streamers in the corona and this time I've managed to bring them out much further from the lunar limb via background subtraction. I tried a variety of gradient reduction tools, but ultimately found that good old Gradient xTerminator yielded the best results for me.

I know there's an etiquette on Astrobin for publishing a new image vs a revision, but I think enough time has passed that no one will confuse this for new data.

My old version of this image is included as a revision.

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.
