That's fair enough Ron, but you're an experienced observer and you knew that.
Poor dumb buggers like me (and other newbies to the game) don't know that. Instead, we are told that a Barlow will double our eye piece collection.
It may not be outright bad advice, but it's certainly misleading and as such, it shouldn't be given.
Fair point?
