NGC 7129 also known as the Small Cluster Nebula is a reflection nebula located 3,300 light years away in the constellation Cepheus. A young open cluster is responsible for illuminating the surrounding nebula. A recent survey indicates the cluster contains more than 130 stars less than 1 million years old. he nebula is rosebud-shaped; the young stars have blown a large, oddly shaped bubble in the molecular cloud that once surrounded them at their birth. The rosy pink color comes from glowing dust grains on the surface of the bubble being heated by the intense light from the young stars within. Some details about this image: Captured this image from the Negev desert Israel on Sep 27-28, 2019, (one night session). it took me a very long time to process this image with some difficulties that I had but finally it completed.
