The Optical Hardware 3x budget barlow is designed to triple the magnification of any 1.25″ eyepiece. As the title suggests this is at the budget end. Very basic single lens gives a much softer image than multi-coated equivalents with more false colour. The body is also plastic. It does however come with lens caps
But if you are on a very limited budget, it is a good way to experiment with different eyepieces / magnifications
As always , check the maximum sensible magnification your telescope will go to without losing too much optical quality
