Description

This is the reuploaded image of the famous double cluster NGC 869/NGC 884, also known as H & Chi Persei. The double cluster lie at a distance of 7500 light years and have an age of 12,8 million years. H&Chi are dominated by five red supergiants and more than 300 blue-white-giants.

This is my second picture where I used the Star Adventurer, but reprocessed in PI.
