Ken,

I'd say for some reason it isn't coming into focus.

I know this is probably blantantly obvious, but your post leaves a bit of
ambiguity to it---you do have an eyepiece in it, right?

Once you adjust the focuser, the image should come into focus quite easily.

Have you tried focusing on something during the day?
