There are lots of cool objects to view with the 4" scope. The pleiades star cluster is brilliant in a small scope with a wide field of view. The Orion nebula starts to show some shape. The double cluster, etc.

With a high magnification the field of view gets effectively reduced so targets race across the FoV.
A 4" will give you excellent views of the moon, open clusters, double stars. It'll give you nice views of Jupiter and Saturn with good conditions.
