If you're looking at a light pollution filter, the Hutech IDAS LPS2 is great but very expensive. They don't do a 58mm filter though. They seem to jump from 52mm up to 72mm - the latter being $309US/$436AU (Ouch!!!). You would need a 72-58mm step ring to attach it to your lens
Sorry can't help you with any before and after shots I'm afraid.
I can tell you that from my location exposures over 5 mins would begin to look fogged out, but with the filter on I can push way past that time with no fogging of the exposure.
Check out my images in the link below to view some stuff done with this filter - "LMC 200mm f4" is the most recent, and I used the filter on that to take 9 x 7 min shots.
Good luck, but it could get very pricey!
