My relatively small scope with a OSC camera set up struggles imaging dim broadband targets like Galaxies under heavy light polluted City skies, however the key is hundreds and hundreds  of short subs ( 30 to 60 sec ).This capture was only just over 4 hours which is not really enough to improve SNR and produce a better quality image , but the weather had other ideas.
