There are different orientations, I have my 2" that screw into the expansion adaptor of my Baader eyepiece directly and does not require to take the eyepices out to adjust. - mine -

My previous webcam, I had to take out the webcam everytime I altered the filter, really annoying. I managed to alter the exposure control better recently so I dont need to do this any more. -

The last option is a double Polarising filter in 2 parts, one is fitted to an adpator that fits into the eyepiece holder (of the scope) the other filter screws into the lense. The eyepice and single filter fits into the eyepice adaptor allowing it to rotate the filter without pulling it out. Although a bit fiddly it is a big improvement. This method does not work on all focusers as it extends the eyepiece further out and may not allow you to focus correctly. (That was a mouthful, hope you understood it) - Cant find a link for the one above, but i do have one myself.
