Sorry you weren't successful on first light. Try during the day, to get a feel for how the whole optical path works.
The optics should always be good enough (even if miscollimated) to show you something that you can get a reasonably good focus on. It is a full Moon so try looking at the Moon first. If you can get a good focus, then good.. Then try to find the Lagoon Nebula. Once you've done all that you're ready to explore on your own.
"Blurry haze" with no help at the focuser sounds like dew to me. Always keep an eye on the glass surfaces along the optical path. (Yes, sorry, there is always more than what you're told before buying your scope.)
