I know there are 2x (which I have two of .. one came with my reflector) , 3x and 5x but I’ve never seen a 4x.. do they exist?  I’m contemplating getting another set of filters so I can keep on set with my reflector and the other with my refractor ..

You’re right about it being on the more costly side but I’ve heard it’s a good brand
