The open cluster NGC 7789 was discovered by Caroline Herschel in 1783 and is also known as Caroline's Rose Cluster. The distance to earth is 8000 light years and the age is estimated with 1,5 billion years, much older than other clusters.
This is the first light of my new HEQ-5 and the TS Photoline 72 f/6.
