h and chi Persei - Double Cluster ( NGC 869 and NGC 884)

This is the famous Double Cluster in the constellation Perseus. It's a popular target for astrophotography and visual observations because it appears relatively large in the night sky. Hence the greek philosopher Hipparcos first "catalogued" it in 130 BC. The real nature of this astronomical object as two star clusters was revealed in the early 19th century by William Herschel. Due to observations with the GAIA Spacecraft, astronomers by ESO discovered that h Persei is sourrounded by an extensive halo which spans until 200 pc (652 ly) around the cluster itsself. Aside from that this gave us an new perspective of how tidal forces in molecular clouds lead to the extinction of star forming regions.

For me it was the first time to shoot a star cluster and the first time is everytime something special. I really like the outcome altough I have to admit that my aim was to make a so called "pretty picture". Therefore I tried the PS plug in Starspike and it's a fantastic tool to add diffraction spikes to your images but it's not the right tool for more scientific applications in my eyes.

Wish you all the best and CS!

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.
