About the Antares 4" f/13 Refractor Optical Tube Assembly...

Since the whole point of a refractor is high-power, high-contrast images, the important thing is to get a refractor with acceptable focal length! Enter the Antares 4" f/13 Refractor Optical Tube Assembly... Long focal length is needed to generate magnification. When refractors, like the Antares Telescope. have a high F/ratio, optical aberrations tend to disappear!

 

The proliferation of short-focus, high-element, ultra expensive refractors that have snob appeal can''t compete with the high-contrast standard Antares Telescope achromat designs. Anyone who has had the pleasure of viewing through any of the legendary long-focus Unitron refractors like the Antares 4" f/13 Refractor Optical Tube Assembly admits that they were among the finest images ever.

 

Antares Telescope refractor tube assemblies incorporate the finest components. Each of the 105mm fully coated standard achromats come from the lens supplier to Vixen brand from Japan. All of these telescopes, such as the Antares 4" f/13 Refractor Optical Tube Assembly feature ultra-fine polishing for the highest contrast, and expensive glass types for the lowest possible chromatic aberration. Tube construction is of 4 inch aluminum irrigation tubing for straightness and each Antares Telescope features triple baffling for complete suppression of contrast killing stray light. 2 inch focuser standard.
