I'll try to keep this as to the point as possible. What is the lowest magnification barlow lens available with a 1.25" barrel?
I'm using a Kowa 883 with a Nagler 3-6mm zoom eyepiece. With the Kowa 1.6x extender attached to the scope, the 3-6mm zoom can focus to infinity; without the extender the eyepiece will only focus between 13ft-150ft. The reason for this is the extender allows the eyepiece to be seated one millimeter deeper (it bottoms out regardless of extender or no extender). Who'd have thought that a single millimeter would make the difference.
I want the barlow for reason beyond it's intended purpose; the eyepiece can't achieve focus without the extender, so I want to use the barlow to cheat. The 3-6mm zoom has a longer than standard barrel, so if I can plug the Nagler zoom into a low power barlow (which should be able to correctly seat into the scope), I can potentially circumvent the focusing issue. So to be clear, I don't want a higher power barlow to try and squeeze out even more magnification, I want the lowest power available just to be able to seat the eyepiece properly.
