Hi mike,
I have the same dob and use my 25mm to scan around too. I live in campbelltowns outskirts tho so my skies are probably maginally darker.
I have to admit that when i first tried to find cent a it was dificult. you should be able to see it tho. I dont know what your conditions were like last night but altho the sky was very clear the seeing was really bad with heaps of moisture in the air. I didnt even bother going out to look.
try on a night of good viewing and you should do well
