The listed magnitude in the paper M(V) = -13.2 is the "absolute" visual
magnitude -- its the apparent visual magnitude *if* the cluster was located
at a nearby distance of exactly 10 parsecs or ~33 light years. To convert to
an apparent visual magnitude, you use the distance to the galaxy. I'm fairly
certain the object I observed in N6946 was fainter than V = 13.2.
