Rene,
I image and observe on the south coast near Ulladulla, definitely don’t need LP filters down this way, I’m up the road from Peter ( Bortle 3 classification)
For observing with my 12” Goto dob I sometimes use a UHC filter on nebula targets like Carina , Lagoon , Eagle , Swan and others
For imaging I use a OSC ZWO Duoband filter between first quarter and last quarter moon on nebula targets only.You can get away with no filters on globular clusters and the like. Galaxies obviously need the dark with no filter
Cheers
Martin
