The core of the Andromeda Galaxy

This is a project I was working quite long on. Beginning with a wonderful clear night in september I decided to go on this stunning target with my CLS CCD filter and exposed in three steps of duration. My wish was a final image without outburned core in addition with some nice details in the outer regions with soft colours. You can find a lot of version at which the processing is overdone just to rise up the outer regions and during the processing marathon I came to similar results, which I didn't really like. After several tries I dediced to share this version according to my feeling, that mostly a little bit less is better than too much. Of course this will not match to everyones taste but I hope you like it nevertheless...

Hubble's Cepheid
The marked tiny little star is the cepheid, famous astronomer Edwin Powell Hubble was searching for so long. Basing on the important works of Henritta Leavitt, Hubble could prove 1923-24 using the famous Hooker telescope for imaging on glas photo plates that M31 is not just a nebula of our milky way, but an idependently galaxy with an enormous distance. So this little variable star in the Andromeda Galaxie changed our complete view to our universe in a dramatic way...

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.
