Product description

Wide-angle, high-definition eyepiece, gas-filled, with a 68° apparent field of view

This 68° field of view eyepiece is waterproof and gas-filled. The gas filling effectively prevents internal fogging, any ingress of dust and moisture and any formation of fungal blooms. So the quality multi-coating is particularly well protected and durable. Cleaning is hence also made much easier, as you can treat the eyepieces with cleaning fluid, also heavy internal condensation cannot penetrate between the lens elements. That all means this eyepiece guarantees perfect observing for many years to come!

And, of course, you won't be making any compromises with image quality - the eyepiece provides a sharp, high-contrast image over the entire field of view - even with 'fast' telescopes. The use of high quality glass and blackened lens edges, together with the patented EMD multi-coating, ensure maximum contrast.

In addition, a foldable rubber eyecup, standard filter thread and a conical locking groove in the stainless-steel barrel come as standard features with this eyepiece. All the 68° series eyepieces are parfocal with one another, which means you won't have to adjust the focus when switching between eyepieces.

Excellent

( 5 / 5 )

I'm using this eyepiece. It has a very wide field of view. Any wider FOV than this is not needed. Stars are sharp from edge to edge (with coma corrector explore sci.). Galaxies are clearly visible in this eyepiece. I was shocked when I saw M82 - it was bright and well defined cigar like shape. The quality of materials is excellent and the eyepiece is quite heavy. Certainly one of my favourite eyepieces.
