M31, the Great Galaxy of Andromeda

M31, the Great Galaxy in Andromeda, or “Antsa” as we call it here. The great galaxy in the north has many names.

I could say that I found the spark for astrophotography after photographing this galaxy with my then newly acquired DSLR. I wasn’t sure if it could be done, but I tried and .. there it was, an almost identifiable blob that definitely was not a star! As my skills and equipment progressed I have returned to this every couple of years, always aiming for a better result. The journey has been long from trying to image through severe light pollution to our own remote-controlled observatory. Like always, I feel that this is a great improvement to my previous picture of M31, let’s see how this looks like again in a couple of years!

The second picture is interesting. It is the narrowband H-alpha image with the red continuum of the galaxy substracted away. The end result is an image that shows only the areas with pure emission, making the knots and twists very clear. Some spiral structures in the center of the galaxy is also visible.

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.
