Whether you're a seasoned astronomer or an enthusiastic stargazer, this precision-engineered Barlow is your gateway to exploring the universe with unparalleled detail and brilliance. Unleash the full potential of your telescope and embark on a celestial journey like never before!

The Flat Field Tele Extender's 4-element optical design minimizes field curvature, and allows for excellent color correction.

It is particularly suitable for high resolution lunar imaging, making mosaics easier to match at the edges with less distortion, and offering better color correction over as much of the field as possible.

A Tele-Extender is a type of Barlow which does not change magnification factor if you vary the distance between the eyepiece or camera and the Tele-Extender unit, so it's ideal for consistent astrophotography results, if you add a filter wheel for example.

Most high power eyepieces have short eye-relief (distance between eyepiece and eye), making them difficult to use with eyeglasses and less comfortable generally. However, with these units, you can use low power eyepieces at high power, while maintaining the same eye-relief.

Premium glass and top quality broadband multi-coatings on all surfaces, along with blackened interior elements ensure the ultimate in image contrast. 

An ideal accessory for high power lunar, solar and planetary observation and imaging, the resulting images speak for themselves.

Threaded for 2" filters with a brass compression ring and rubber grip.
