Tele Vue 2X Powermate image amplifier for 2" eyepieces, with 1.25" eyepiece adapter

$342.01

12 Review(s)

If you need a very high quality 2x Barlow for 2" eyepieces, look no further than this TeleVue Powermate. While not technically a Barlow, this unique new 4-lens image amplifier performs the same functions, but at a higher level of optical correction. Barlow lenses have a negative power that diverges field rays, lengthening the effective focal length of the telescope and increasing the magnification . . .
