IC10 is an irregular galaxy in the constellation Cassiopeia, it is a member of our local group of galaxies. The apparent distance between IC 10 and the Andromeda Galaxy is about the same as the apparent distance between the Andromeda Galaxy and the Triangulum Galaxy, which suggests that IC 10 may belong to the M31 subgroup.
IC 10 is the only known starburst galaxy in the Local Group of galaxies. It is located around 2.2 million Lightyears from Earth.
This target was one that I was unsure how it would turn out, after two nights imaging and 10+ hours of total exposue I believe this target is too dim for my current equipment. It was challenging to process and I was in two minds about actually uploading it but decided to put it up anyway as it is at least a record of time spent pushing the limits of what I can do.
