University Optics 2-inch 2X Barlow Lens (Used)
Properly designed fully coated optics with exceptional baffling for high contrast views. manufactured in Japan
Only a TeleVue BIG Barlow (for much more money) could keep up with this University Optics 2X 2" Barlow.
The inside of this Barlow is a lesson for many flashy accessory rebrands out there to learn from.
Baffling telescope accessories against internal reflections is a neglected art which makers seem to have forgotten about.
If you own a quality eyepiece then treat yourself to good Barlow.
