M31 | Andromeda Galaxy (HaLRGB)

Revision title: Adam Block's Continuum Subtraction Method

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

The image of M31, the Andromeda Galaxy, was obtained through the Telescope Live Network using an HaLRGB palette. Today, after almost a week after the HaOIII Andromeda was published, it seems just a "traditional" image. It is yet the best I could process so far. I am waiting for the clouds to part from Northern Italy, hoping for some imaging sessions with my own equipment.
The HaLRGB technique creates a high-resolution and detailed image. I tried to work mainly on the bright central region of the galaxy, also known as the nucleus, which is visible, as well as the galaxy's spiral arms, which are composed of young stars and gas clouds. The blue regions in the image represent areas of intense star formation, while the red regions indicate the presence of hydrogen gas. The galaxy's halo, composed of older, reddish stars, can also be seen. Additionally, the image may reveal faint features such as the galaxy's outer disk and any companion galaxy that may be present in the field of view.

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.
