I have a short tube 2x barlow that works okay. The 3x short tube barlow has multiple internal reflections which cause the image to blur. I don't know enough about the optical design to say if this is intrinsic to the short tube design, but I think it is the reason that meade discontinued selling their 3x barlow.
Good but not what I had hoped

I got it very fast and in perfect and new condition! I was a little disapointed though with the light gathering of this lens. It does increase the power of whatever lense you are using but things look very dim as well. Not very good for viewing land objects but the moon looks great with this. I might try the 2x power next and see if I can't gather more light with that! Over all, not a bad product, just not as good as I had hoped!

IT WAS A VERY NICE AND EASY PURCHASE. THE BARLOW LENS IS NEAD AND USEFULL, I LOVE IT.
I don't use it much any more

It works like it should (3x zoom) - of course it distorts the image, but you can see your image much bigger than without it.
Great with the basic lens

Right now we only have the 26mm lens that came with our Meade 90ETX. This 3x Barlow was the first add-on lens that we bought - and we're glad that we did. Images magnified with the 26mm + 3x Barlow remain crisp and well-defined.
I can't wait to try this baby out with some higher power base lenses.
