NGC 7789 Carolines Rose

NGC 7789 with the collected Ha data,when I decided on this object, I suspected that there would have to be dust and ha there in the end of our Milky Way.Continuing to expose NGC 7789 in the following clear nights was the right decision.At that time, the moon appeared in the second half of the night. So I switched to the Ha filter and realized that it is really like that, Ha is quite present in the area of Cassiopeia.Caroline's rose includes many red giants, so this beautiful star cluster appears in the warm orange-red light. The additional Ha radiant in red makes this very old open star cluster even more impressive.Such star fields with all the differently shining stars fascinate me every time anew.
