If, like many councils, they are moving to broad spectrum LEDs to save money then your CLS is going to be less useful as time goes by. Narrowband imaging is where most city slickers are headed, but you will need a good mono camera and filter set, and be ok with shooting blind. Nothng beats a dark site.

Absolutely agree with everything said here and all bets are definitely off for the future as lighting policy is likely to change. My post wasn't really asking is it better to use a CLS in an urban sky than not - because the answer to that is obvious it was more noting the empirical evidence that, at the moment at least, it would appear that images taken from home with the filter are just as good as one taken from Astrofest without the filter?
