Galaxy NGC (New General Catalog) 3486
This galaxy is about 30 million light-years from Earth and is located in the sky between the bottom of the big dipper and Leo the Lion. It has a small bright core, perhaps containing a small black hole. The uniform spiral arms are rather dim. The brighter blue stars indicate new star births ongoing. Overall, this galaxy is quite dim and difficult to expose. This is a 2hr 5mn exposure.
