IC 1396 - The Elephant’s Trunk Nebula SHO

I've imaged this one in the past and never had a result that I really liked. This one ended up being a bit better through added imaging time. I used Bill Blanshan's new SHO normalization pixelmath to get my colors dialed in before tweaking with curves adjustments. His new tool is really powerful and helps arrive at an interesting SHO color palette. I'm still struggling to get my back focus dialed in with the Evostar 80ED. I ordered the wrong sized Baader Varilock so I'm in the process of exchanging it. Hopefully this will let me fine tune my settings as the spec of 55mm results in badly elongated stars in the corners. I experimented with electrical tape in multiple layers to increase my spacing to where the stars were semicircular. Oh well, time to figure out the next target...

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.
