Barlows to take a filter?

Hi all,

I have several 1.25" barlows and a GSO 2". I have been trying to add a filter to the optical path but so far, only my Rini 3X is threaded for filters but it is one of the long barlows and doesn't fit well into a diagonal.

I noticed that Orion states that their shorty barlow has a barrel threaded for filters. It doesn't show in the photo on the website so I assume it is inside the barrel. Can any one confirm this?

clear skies,
dan

I have an Orion Shorty-Plus 2x barlow and it does not take filters. But it accepts a 1ΒΌ-inch eyepiece that has a filter on it.
