  • 5X short Alstar Barlow Lens offers an ultra-short design and apochromatic correction you can combine the Barlow lens with an eyepiece or a camera; Observe objects with remarkable sharpness and excellent contrast
  • 4-element Barlow: The combination of three lens elements means the Alstar 5X short Barlow provides particularly clear and sharp images; Filter thread for any 1.25 inch filter
  • Fully Multi-Coated Optics: A significant advantage of this lens is the complete absence of chromatic aberration typically observed in achromatic lenses; Each lens element is multi-coated ensuring high light transmission and consequently producing a bright clear image
  • Ultra-Short Length: Use this Barlow where in particular where you need a shorter length; Sometimes the total accessory length with eyepiece, adapter or camera can be rather long; The Alstar short Barlow has a length of only 42mm
  • Compression Ring Design: The built-in compression ring secures your eyepieces across a surface rather than at a single point. This design ensures enhanced protection against scratches and deep grooves
