Achromatic 2-element Barlow Lenses from TeleVue
The Barlow lenses consist of two multi-coated lens elements. The Barlow lenses increase the telescope focal length and thus also the magnification. With a Barlow lens, a long focal length eyepiece with a pleasant view can also be used for high magnification observation of the moon and planets.
The Barlow lenses can also be used photographically. Barlow lenses are often used for planetary photography with astro cameras. Suitable adapters for T2 can be found in the accessories section. Especially with DSLR cameras the distance of the sensor is higher than with eyepieces. This increases the magnification effect slightly.
Eyepieces and adapters are attached gently and securely via a ring clamp. The very stable housing rounds off the good design of the Barlow lens.
