Barlow lenses offer an easy, economical way to
increase the magnification range of your eyepieces,
and Celestron carries an assortment of these highly
useful lenses. A Barlow lens doubles the magnifying
power of your eyepiece by doubling its effective focal
length. For example, an 18mm eyepiece used with a
2x Barlow lens would have the magnifying power of
a 9mm eyepiece. It’s like having two eyepieces in
one!
If you’re looking for an affordable way to achieve
high-power viewing of the moon and planets, double
stars and even close-up views of terrestrial subjects, a
Barlow lens is the answer.
Barlow lenses mount into either your telescope’s focuser or visual back.
The Economy models of .96" and 11
/4" are good choices when you want to
expand your power ranges at a very economical price.
Celestron’s premium quality .96" and 11
/4" achromatic Barlow lenses (#93502
