Andromeda galaxy (M31) in the soup of Ha and OIII.

M31 captured in RGB and HOO showing our neighboring galaxy in the soup of Ha and OIII ionized gases possibly from our galaxy(?). Approximately 40 hours were spent imaging this target. I, however, was more interested in seeing the relative levels of the surrounding Ha and OIII emissions, thus, could not use the background extraction tools. Thus, all sub-frames with external gradients (primarily moon) must be removed. In the final integration, I used about half of the subs for a total integration time of about 20 hours. Due to the fact that Ha and OIII are processed equally without any selective masking, their intensity levels can be compared directly to those of the M31 nebula. Despite the presence of Ha/OIII signals around the main target, they are relatively weak.

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.
