One of the nicest globular clusters viewable north of the equator is M22, located in Sagittarius. It is very large and rivals M13 in sheer beauty. This was taken at the home site with the Tak Sky90 unguided. Star colors are very apparent, with the red supergiants scattered about the globular. Some field curvature is evident with the larger H9C chip, but this will be taken care of with the f/4.5 focal reducer/flattener in the near future.
