The Lightwave Hyperwide TM 2" 20mm Eyepiece features an amazing 100 degree apparent field of view, for a truly immersive viewing experience. The apparent field of view is so wide, that one doesn't really notice the field-edges.

This is achieved by means of a computer designed 9-element optical system which delivers a high contrast image with excellent edge sharpness at a wide variety of focal lengths. Colour correction is very well maintained across the field, and the normal aberrations present in optical systems are very well controlled. Lateral colour aberrations are controlled by the use of special dispersion glasses doped with rare-earth elements.

Blackened lens edges, and fully multicoated internal surfaces enhance image contrast, and stars appear as bright, sharp points against a dark background.

The Lightwave Hyperwide TM 20mm has a comfortable 14.5mm eye relief, and the folding rubber eyeguard eliminates stray light, delivering an immersive experience that is out of this world.

This eyepiece is quite substantial weighing in at 875 grams, and the oversize shock-absorbing rubber grip and tough metal casing give it a solid, durable feel.

To avoid dewing up, use a 2" - 4" dew heater wrapped around the rubber grip and operate your dew controller with around 30% power to warm the entire eyepiece up.

The 20mm Lightwave Hyperwide TM eyepiece has the larger format 2" barrel. Your telescope requires a 2" diagonal or focuser. Supplied in a hard box with foam inserts, and dust-caps.

Comment from Altair Astro Staff: We've tested this eyepiece ourselves after reading a positive magazine review, and found the field correction and aberration control to be very good indeed. Day-time viewing is a real treat, and one gets a sense of being right near the subject. Viewing the moon or extended deep-sky objects with the Lightwave Hyperwide TM is just how we imagine looking through a spaceship window might feel. Contrast and sharpness have not been sacrificed to achieve this huge, evenly illuminated field of view, and in our opinion, this is the best value eyepiece of it's type we have been able to source to date. We tried several samples with similar specifications, but this one outperformed them all. Whilst they work very nicely with most telescopes, in particular, we recommend the Altair 102mm 115mm and 130mm refractors for use with these extraordinary eyepieces. These telescopes have naturally flat fields, which really do justice to the enormous 100 degree apparent field of view
