A Barlow lens is the astronomy accessory that keeps on giving! Insert it
between your eyepiece and your telescope to get double the magnification
instantly. Let’s say you have two eyepieces in your accessory case, a 10 mm
and a 25 mm. Add a Celestron Omni 2X Barlow Lens to the mix, and now you have
four magnifications to choose from. Combining this lens with the 25 mm
provides double the magnification, or the equivalent of a 12.5 mm eyepiece,
while the 10 mm gives you the power of a 5 mm eyepiece. Eye relief is the
distance your eye has to be from the first lens in the eyepiece in order to
see the full field of view. When you use a Barlow lens with an eyepiece, you
get double the magnification, but the eye relief is not affected. This is a
good thing, because normally the shorter the focal length of the eyepiece, the
less eye relief you have. In other words, a standard 10mm eyepiece, as a
general rule, will have better eye relief than a 5mm eyepiece. Bonus! The
Celestron Omni 2x Barlow comes in a sleek, silver package. The two-element
optics are fully multi-coated, and the edges of the lenses are blackened to
cut down on internal reflections. The 1.25” barrel will fit in standard 1.25”
focusers and diagonals, and the Barlow will accept 1.25” eyepieces. A metal
thumbscrew locks the eyepiece firmly in place.
