Hi Suzy,Re IC 5148/5150,In your light polluted sky I would say it would be nearly impossible to see this object, as the PN has a very low surface brightness.
As I noted in my post on your Observing Target's post I find that neither O111 or UHC Filters made little or no difference.
You will be able to pick it up in a 10"scope from a dark sky site.
Nice report on
NGC 6723 GC & NGC 6727 
It is a great target both visually and photographically
Cheers
