Can't see the Moon

I live on the northern end of the Gold Coast in Queensland, and have purchased a 2nd hand Sky-Watcher Traditional Dobsonian Telescope 254mm/1200mm (10") for Christmas for my 11yr old daughter who wants to be a astrophysicist (at this point in time). The telescope still has 2yrs of warranty (the owner purchased it new from Slacks Creek in Brisbane).


All caps are off, and we can locate the moon with the finderscope, but no matter what we do, we can't see it through the focus tube using a 10x or 25x eyepiece.


I left the telescope outside to come down to temperature for over 30 minutes.


I am seeing a brilliant bright line when looking through the focus tube, it appears in the centre coming from the edge of the angled secondary mirror.


What obvious thing am I doing wrong?



Cheers
