Versatile 72° ED Views Across Eight Focal Lengths

The 72° ED Series pairs a comfortably wide, well-controlled apparent field with extra-low dispersion (ED) glass optics, delivering sharp, high-contrast views with reduced chromatic aberration across eight focal lengths.

From the high-power planetary detail of the 6.5mm to the ultra-wide, low-magnification sweeps of the 40mm, the series covers the full range of visual astronomy in one consistent optical design.

Generous eye relief keeps every focal length comfortable for eyeglass wearers and extended sessions, with a 1.25-inch barrel on the shorter focal lengths and a 2-inch barrel on the longer ones for use in larger focusers.
