John, I think the Barlow may just be physically too long to allow the focuser to reach focus. In other words, if you could get a few more turns of the focus knob it would probably come into focus.

You may just need a different brand or physical size Barlow.

Did you purchase the scope from a local dealer? If so they can probably help.

Hopefully others will chime in and offer other possibilities.
