#126 2x Barlow Lens (1.25")For The ETX and Digital Electronic Series (DS) Telescopes:

The #126 Barlow Lens doubles each eyepiece power while maintaining excellent image corrections. For example, a 9mm eyepiece used with the Model DS-60 yields a power of 78X; when used in combination with the #126 Barlow Lens, the same eyepiece yields 156X. With Meade DS-Series refractors, first place the telescope’s diagonal mirror into the focuser, followed by the #126 Barlow Lens and an eyepiece. With DS reflector models the #126 Barlow is placed directly into the telescope’s focuser, followed by an eyepiece.
