anyone got any experience of LPR filters? They are quite a bit of wonga but it'd be worth it if I could see more.

Yeah seriously considered one myself, but would need to know if it was worth it before splashing out too !!

I have one that screws on te back of my C8, I'll bring it to the next observing evening. It's very good for dealing with low pressure sodium, but now that the fasion is for those ghastly high pressure lights, the filters offer very little advantage, if any.
