Stupid question...but...

I assume I do screw filters to the back end of the eyepiece, right?

There are no stupid questions, if you are not sure always ask,

Apart from the 'old-fashioned' Sun filters which should be slung in the dustbin immediately . . .

No, its 'just' a light pollution filter. Whilst it is in general okay dark in my backyard but ha a nasty streetlight behind the neighbors house that is pretty disturbing.

Anyone got any experience with those filters?

Nothing very favourable TBH. I find nebula filters a great help, but their LP cousins have done very little for me. It could be I have the wrong type of LP for them to help. I prefer to spend the money on tanks of gas and getting to dark sites.

Others have quite a lot if success if they have the type of LP that these filters block. Unfortunately I don't.

I hope your street light is the type they block, if so.......happy days

I've got one that works perfectly when I'm viewing to the West as it cuts the glow from an old sodium lamp completely , in the East the new estate has some other kind of lights that it doesn't touch at all.
