Explore Scientific 2" 2X Focal Extender - FE02-020

This 2x focal extender doubles the magnification of any 2" or 1.25" eyepiece you already own, turning three eyepieces into six usable magnifications without buying more glass. Because you're extending a lower-power eyepiece rather than switching to a higher-power one, you keep that eyepiece's more generous eye relief, a real benefit for eyeglass wearers or anyone pushing a fast telescope to high magnification. Explore Scientific also makes 3x and 5x versions if you need a bigger jump.

• 2x magnification, 2" barrel: accepts both 1.25" and 2.0" O.D. eyepieces and camera adapters.
• Fully EMD-coated optics: all air-to-air lens surfaces coated with edge-blackened elements for superior contrast.
• Retains eye relief: extending a lower-power eyepiece keeps its more comfortable eye relief versus buying a high-power eyepiece outright.
• Compact size: 118mm long, 66mm wide, and 20 oz (0.57 kg).
