Information:

This new range of wide angle eyepieces have some advanced features not usually found on eyepieces within this price range.

The lens elements are constructed with high index glasses for excellent colour correction.

The lenses also feature contrast enhancing blackened edges and are fully broadband multi-coated; for maximum light transmission.



Specifications:

The mechanical features of these sleek oculars are just as impressive; with all focal lengths having fold-down rubber eyecups; 1.25" filter threads; anti-reflection threaded barrels for maximum contrast; upper barrels are black anodized aluminium with a rubber grip ring.

Finally the entire 1.25" wide angle range is par focal; so refocusing when swapping between eyepieces is not required!

Apparent field of view:
8mm: 60 degree
12mm:60 degree
17mm:65 degree
20mm:65 degree

All eyepieces in this range feature a security ring; recessed into barrel; to help prevent eyepieces from falling out of focusers and diagonals.
