IC 1795 is an emitting nebula located approximately 6000 light years away in the constellation Cassiopeia . It covers a field of about 20 arc minutes , which corresponds approximately to 70 light years.

I capture this using my William Optic FLT110 riding on my old Orion Atlas.

Let me know what you think.
