Celestron 10in Dobsonian Problems?

Hi I am new to astronomy. I bought a 10″ Dobsonian from Opt with several lenses. 2″ Barlow, 9mm & 30mm Pelosis and the 2″ that came with my telescope.

Now I live in Costa Mesa, Ca so this may be part of the problem, but I can not see anything. Stars appear blurry no matter how much adjusting or swapping of lenses I do. I can’t see any nebula or galaxies. When Jupiter and Venus come up they just look like blurry little stars.

I always put the telescope outside 1 hour before trying to view anything in order to let the mirror cool down. I have a laser collimator and use that to align the telescope before viewing. Does anyone have an idea as to why I can’t see anything?

Thank you
