It really depends on where you are located - you mentioned that you do a lot of observing in dark sites - in that context the benefit of a LPR filter will be limited. Unfortunately, if you live in the heart of a big city and that is where you are likely to do most of your observing then a LPR filter is pretty useful. My advice is if you are going to buy one then go all the way and don't cut any corners on quality etc. I have an Astronomik CLS and it turns the back-ground sky from a bright grey hue to a very dark grey. Sadly, the concept or sight of a black sky is something foreign to me other than on depictions I see in photos/television etc
