Home Accessories Barlow Lenses Barlows 2 Inch Altair Lightwave 2x 2 Inch Flat Field Tele Extender Barlow
The Flat Field Tele Extender's 4-element optical design minimises field curvature, and allows for excellent colour correction for owners of telescopes that can use 2" accessories. It is particularly suitable for high resolution lunar imaging, making mosaics easier to match at the edges with less distortion, and offering better colour correction over as much of the field as possible.Please note - this is a 2" barrel version requiring a focuser equipped to take 2" axxessories.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 astro-photography 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.
Wow!!, Just WOW I've been trying to source a 2" barlow and came across the Altair Lightwave and so glad I did. Superb optics, imaged Olympus Mons on Mars with no issue. Harrison Telescopes were very fast to delivery . Very happy. (20/10/2020) Mike Read - Wiltshire
