Elephant Trunk Nebula 2023

My 2023 rendition of the Elephant Trunk Nebula, captured from my back yard in Arlington, VA. I gathered 10hr of Ha, 12hr of OIII, and 7h SII with my AT80EDT, ASI1600MM Pro, and Astrodon filters.

After stacking, I decided that I wanted to aim to print this one, so I re-stacked and drizzled 2x. In PI, I used BXT on the frames individually, then extracted the stars. I stretched each frame with GHS, playing with the symmetry point to try to add contrast to the details and all the stuff going on in the nebula. The three filters were combined in SHO to generate the tricolor image. I went back to the Ha and further sharpened, and used HDRMT to emphasize the contrast a little more before combining this with the tricolor images to make an LRGB (really HaSIIIHaOIII).

I pulled a TIFF into photoshop, cropped to print dimensions, and made a series of 8x10 test prints, adjusting brightness and curves as needed to get the print I wanted, before making a final crop and printing 13x19.

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.
