Explore Scientific Visual Accessories

Explore Scientific visual accessories cover the parts between the focuser and the eyepiece. The range includes 99% reflective diagonals in 2" and 3" sizes, Focal Extenders in 2x, 3x and 5x versions for 1.25" and 2" eyepieces, and a BinoViewer for observing with both eyes.

Focal Extenders raise magnification for the Moon, planets and double stars without changing eyepieces, while the large diagonals suit refractors and SCTs fitted with wide 2" or 3" focusers.
