Antares 3x 1.25" Twist-Lock Barlow (UB3STL)

Antares 3x 1.25" Twist-Lock Barlow

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 Antares 3x 1.25" Twist-Lock Barlow is a fully multicoated achromat with 27mm aperture and increases the focal length (and eyepiece magnification) by 3 times.
