Messier 38 is an open cluster located in constellation Auriga. It has diameter 25 light-years and it’s approximately 3500 light-year away from Earth.
I managed to capture two open clusters this night already (M39 and M34) and there is still one to go (M35). Therefore I didn’t dedicate a lot of time on M38 – this means that the picture is an integration of one hour of exposure time.
