Sh2-263: Same object, same night, different hemispheres (Image 1/2)

On January 15th, I had the opportunity to shoot Sh2-263 from my backyard in Pennsylvania while simultaneously shooting it remotely from Chile. The approach for each location was entirely different, yielding two unique views of the same object.

This image: From DeepSkyChile, where the skies are incredibly dark, I shot R, G, and B data with a TOA130 at f/7.7. Not only does this frame Sh2-263 alone, but the broadband filters reveal the embedded reflection nebula vdB 38, which is completely invisible in the narrowband image.
The other image: From light polluted PA, I shot it with my Tak FSQ-106ED at f/3.7 using narrowband filters. This allowed me to frame it in the context of that area of Orion, including Sh2-265 and edge of the Angelfish Nebula (Sh2-264). In this area, the SII signal is weak, and the OIII is almost nonexistent. (OIII appears in the core of Sh2-263, but this seems to just be picking up vdB 38, not true OIII signal.) For this reason, I used an HOO palette, which ends up being fairly monochromatic. Nonetheless, the wave-like structures in this area are beautiful.

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.
