This image shows you a medium scaled face-on galaxy in western part of a minor constellation of Antlia in lower south skies in spring night.
NGC2997 has a size of about 10 arc minutes and we can appreciate clear and well-proportioned spiral structures.
Although it might be difficult to observe the galaxy at Japan because of its lower meridian latitude, this image can show us several H-alpha regions along its arms.
It's estimated that the galaxy is about 45 millions light years away.
