SH2-278 - The Smoke Monster's Lair

Nestled between the Orion nebula and the Witch Head nebula, SH2-278 is an often overlooked dark nebula complex rimmed with abundant Ha emissions.

The blue clouds are areas of interstellar dust that are reflecting blue light from nearby bright star Rigel. Rigel is also responsible for illuminating the nearby Witch Head nebula.

This image was captured with my FSQ106 at the same time as the larger RiDK400 was imaging a closeup on SH-278. That closeup image was my first IoTD. I tried to incorporate that data into this image in order to bring out more detail in SH-278. However, I had to give up after many hours of trying. The small field of view with the RiDK made it to difficult to blend. Only a very small improvement was visible after blending in the sharp edges of the RiDK data.

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.
