The Zero Magnification Sight Tube offers a wide, uncluttered field of view for practical sextant work.

• Clear, lens-free tube eliminates fogging and smudging from spray
• Zero magnification provides 3–4x wider field than a 4x telescope
• Ideal for horizontal angles and object identification relative to one another
• Aids celestial sights in rough weather by making targets easier to keep in view
• Designed for Astra IIIB but fits most metal sextants with a standard telescope slot
• Durable, high-temperature-resistant plastic with dulled interior and matte black exterior; accepts slip-on rubber eyecup (Item #0505)

Choose the sight tube when you need simplicity, reliability, and maximum field of view.
