Messier 97, also know as the Owl Nebula, is a planetary nebula in Ursa Major. It’s tiny, only a bit over three arc minutes across, making it about 1/10 the apparent diameter of the full moon. Even for a long focal length telescope like this one it end up being a fairly tiny part of the field.
I see different distance estimate but the mean seems to be around 2,400 light years.
This is 19 hours of HOO data.
