From its pristine CNC-machined aluminum tube painted powder white, to its stylish gold accents, the beautiful new William Optics GT71 APO Refractor is an aesthetically pleasing telescope.

  • Each lens is fully multi-coated and contains a unique super-high transmission coating (STM) on each surface




2" V-Power Focuser



  • 1:10 dual-speed ultra-smooth new 2" Crayford focuser with no image shift up to 15 lbs. for satisfying astro-imaging sessions
  • Two locking screws on angled positions for enabling applications requiring a heavier load capacity are included
  • Stainless steel inserts on both sides and the rear provide support for taking on heavier payloads without any problems
  • Graduated scale for correct camera alignment




Patented Design



  • Stainless steel inserts on both sides and the rear provide support for tackling heavier payloads without any problems
  • Graduated scale enables correct camera alignment
