Double Cluster: NGC884 and NGC869

This is the final version of the image I took few weeks ago.

These beautiful open clusters are located in constellation Perseus and are visible with naked-eye. They are also quite close to each other in space because their distances to earth is about 7600 and 6800 light years.

Photographed through SkyWatcher ED80 Pro with QHY9.
Exposure: luminance 10*5min and colors 10*3min (RGB)
