We have a wide range of Barlow's and focal reducers / field flatteners available form the worlds top designers.  

 

                    1.25"  & 2" Barlow lens                        

 

University Optics Klee 2.8x Barlow

 

The Klee is a quality compact 3-element Barlow and is well corrected for spherical aberration, longitudinal and lateral colour. It features a fully air-spaced lens system. The six air-to glass surfaces are multicoated for 96% light transmission. Weighing in at only 2.6 oz. this is the lightest, most compact Barlow on the market!

University Optics Klee 2.2x Barlow

 

The Klee 2.2x Barlow is the latest quality Barlow from University Optics.  This new Barlow  will set new standards in exquisite performance. It offers the same lens quality as the Klee 2.8 featuring a fully air-spaced 3-element design with great spherical aberration and lateral colour correction lateral colour as well as 96% light transmission. The 2.2 and 2.8 Klee Barlows are well suited for visual and imaging applications.

Parks Silver Series 2X Barlow Lens

 

The 1.25" Parks Silver Series 2x Barlow accepts both 1.25" eyepieces for visual use and camera T-rings for prime-focus astrophotography. Features 2-element, fully-multicoated optics.

Parks Gold Series 2x Barlow

 

1.25" Parks Gold Series 3-element 2x Barlow

Double the number of eyepieces by doubling their power with the Parks Gold Series 2x Barlow. Designed to achieve professional performance with a full 26mm of clear aperture for wide-field viewing and multicoated lens for full light transmittance.

University Optics 2" 2x Barlow 

 

This University Optics barlow  is precision machined, fully multi-coated that features a quality 2-element achromatic lens.  A nice 1-1/4" adapter and captive bolt case round out the package.

University Optics 2" 2x  ED Barlow

 

This University Optics ED Barlow in the same as the barlow to the left but uses high-index glass for even better performance.  A nice 1-1/4" adapter and captive bolt case round out the package.

 

              Focal reducers - Field flatteners                

 

William Optics 2" 0.8x focal reducer / field flattener

 

This quality 2” reducer/field flattener comes with a CCD camera adapter and is suitable for refractors with focal ratios from f6 to f10. In addition to reducing the focal length by a factor of 0.8 for fast photography, it works as a flattener of the field curvature for sharp,  pinpoint stars in your images. It is especially recommended to imagers using  CCD cameras. Comes complete with brass compression ring and dust covers.

 Lumicon 1.5x - 1.8x Multiplier/Field Flattener Lens

Custom computer designed to increase image scale with the flattest possible field for photography with fast Newtonian Telescopes. This lens is suitable for use with f/3.5 to f/6 systems. It will turn an f/6 system into an effective f/9 or f/11 system. Excellent for planetary work and splitting double stars. Both lens surfaces are fully multicoated for minimal light loss. The Multiplier lens yields a flat field of optimum focus and is ideal for use with flat field eyepieces such as the TeleVue Naglers or Pentax XLs.
