Do these work as well as advertised? almost all of the time ive spent observing has been with moderate light polution, would filters such as

help to get better detail out of objects?
Also, do you need a filter selector to use filters? or would that filter fit into my eyepiece?
my eyepieces are basically in 2 parts, theres a metal barrel that can be unscrewed, and a black bit with all the optics in it, am i correct in thinking that the filter would go in between these?
