Hi Robert,

Use: Go To... Nebula... PK (Strasbourg). Then enter MyCn 18.
(Alternatively, enter the "real" PK identifier, 307.5-04.9.)

This is definitely not an obvious thing to do. I'd like to
have a Go To... Nebula... Planetary function that would bring up
a list similar to that for, say, globular clusters and nearby
stars. (Except that it would be a lot bigger.)
