Swarovski's posh spotting scopes are hallmarks of the distinguished brand. They're available in two objective sizes, straight or angled viewing, and with regular or ultra-low dispersion glass. It is entirely a personal preference which cannot be determined except from experience, but many prefer anlged scopes for extended observations or when sharing a scope amongst people of varied heights. The 65 mm size still lets in a sizeable chunk of light but can easily be tolerated upon a long hike. Rotating tripod collar with detented click stops. Retractable lenshood.
