Here near Phoenix we have considerable light polution. The local club has Lumicron UHC and that cuts sodium but also cuts visible light significantly. When I hold it up with the naked eye I can just make out Procyon. Although my memory may be failing, I thought I had an almost clear filter with the 8" Meade I had several years ago. Any suggestions to cut the sodium without cutting the rest?
