Sh2-235 • Rare Collision Nebula in HSS

I ended up totally reworking this. This is one of the few Ha and SII bicolor palettes I have processed. Sh2-235 is very unusual in that SII is way more prominent than OIII. While SII falls more in the red spectrum, I liked the way the texture popped more with the SII mapped in blue. My second goal was to pull out more detail in the core of Sh2-235.

SH2-235, as designated in the Sharpless catalog. It is a kidney shaped HII region formed when two large clouds of gas collided. The nebula is part of a larger complex consisting of SH 231,232 and 233. The complex lies in the constellation Auriga. The distance to SH2-235 is somewhat unclear. Observations made with the WISE space telescope indicate it lies between 5,219 and 8,154 light years from the Earth. Other estimates place it approximately 6,000 light years distance. Infrared studies of the object reveal extensive formation of new clusters of stars embedded within the cold clumps of gas and dust within the nebula.

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.
