Cleaning internal elements in EP's?
I recently got 2 EP's and a Barlow from Andrews all of which have visible debris/dust inside the unit (behind outer element)
Can't find any info on cleaning the internals.
Can it even be done? There are screwed setting rings so I know of you can tear them down but not prepared to do so if it is best left alone. Mind you I am confident of doing delicate work.
Many thanks!
