AEROTM 2" ED Eyepiece (2"/50.8mm) with 35mm Focal Length from OVL (Optical Vision Ltd, the official Skywatcher distributor in the UK and Western Europe).
Multi Coated, with 68° Apparent Field

The 2” Aero ED SWA eyepieces feature a 6-element construction in four groups. Exotic ED glass is employed in the design to significantly reduce false colour.
These eyepieces all feature impressively wide 68° fields of view, with virtually distortion-free images.
Multi-coating is applied to all air-to-glass surfaces to increase light transmission and image contrast.
All models feature edge-blackened lens edges and are parfocal.
Twist-up rubber eyecups and generous eye relief for spectacle wearers. Finished in high-gloss anodized aluminium with knurled rubber grips.
The eyepiece barrels are threaded to accept standard 2” filters.
Available in focal lengths of 30mm, 35mm & 40mm, with eye relief of 16.7mm, 17.5mm & 20mm respectively.
