1.25 Inch Fully Multi-Coated Metal Barlow Lens 2X, with M42 Thread Camera Connect Interface - for Telescope Eyepiece

The Celticbird 1.25" 2X Barlow Lens doubles the power of any 1.25" telescope eyepiece it's used with.

The practical Celticbird 2x Barlow Lens effectively doubles the number of telescope eyepieces at your disposal.

The Celticbird 2x Barlow Lens doubles the magnifying power of any 1.25- inch eyepiece, essentially dividing the eyepiece' s focal length by a factor of 2.

For example: Using a 25mm eyepiece in the Celticbird 2x Barlow provides the same magnification as a 12.5mm eyepiece would normally exhibit (25 / 2 = 12.5).
