2-inch Barrel

This collection covers 2-inch barrel eyepieces and 2-inch filters, the format built for wide true fields at low power. The larger barrel passes more of the field stop than the standard 1.25-inch fitting, so long focal length eyepieces deliver sweeping views of star fields and deep-sky targets.

Every item here is from Explore Scientific: long-focal wide-angle eyepieces (including 52-degree designs) plus 2-inch nebula and neutral density filters. Confirm your telescope has a 2-inch focuser or adapter, since the barrel will not fit a 1.25-inch fitting.
