Barlow, 1.25" , Twist-Lock, 3X
1.25" 3X barlow with twist-lock eyepiece holder, 27mm aperture doublet, Fully Multicoated.
Antares Twist-lock barlows make for easy eyepiece in-out and work with any barrel format. These extend focal length, reduce spherical aberration, extend eye relief and have T2 camera thread with the Twist-lock collar removed. The 1.25"UB3STL is a fully multicoated achromat with 27mm aperture and increases the focal length (and eyepiece magnification) by 3 times.
