Denkmeier 21mm Two Eyepiece Set - 1.25"

Denkmeier 21mm Eyepiece Set

The new Denkmeier 21mm eyepieces have been designed specifically with binoviewing in mind. Over one year in the making, users are raving about the awesome contrast delivered by way of our super multi-coatings. We use only the finest Japanese raw glass for these eyepieces, and each optical set is carefully examined with loupes in our Maryland, USA facility and tested in a Denkmeier Binoviewer before being assigned a number and shipped to the customer. Superb and accurate machining of all of the anodized aluminum housings means perfect image merges every time. The 20mm eye relief and 65 degree field of view provide an amazing porthole-like effect. They are specially designed to provide maximum illumination with the Denkmeier Power x Switch Systems.

Denkmeier 21mm 1.25" Eyepiece Set Features...

Denkmeier eyepieces utilize special high index glass elements and are Fully Multi-Coated on all air-to-glass surfaces. Each eyepiece includes rubber knurling for secure gripping. They are black anodized and laser engraved with the Denkmeier logo. The special lightweight barrels are black anodized, and the world's first rotating batwing eye-guards are standard on every eyepiece. This allows the eye-guard to be properly positioned by the user after the binoviewer SCD Holders are turned for fine focus. Sporting 20mm of eye-relief, eyeglass wearers may fold the eye-guards down and a soft rubber rim remains to ensure that eyeglass lenses are never accidentally scratched by the top surface of the eyepiece.

The very large 65??? apparent field of view (AFOV) provides amazing wide field vistas. Outstanding color correction makes lunar and planet viewing a joy. Incredible contrast for Hydrogen Alpha solar viewing is the result due to outstanding coatings. The edge illumination is optimized when using SCTs, Refractors or Newtonians with the Power x Switch Systems as compared with other long focal length wide-field eyepieces. Each Denkmeier Eyepiece includes a plastic protective bolt case and also includes plastic eye and field lens caps.

Denkmeier 1.25" Eyepiece Set Reviews...

"Got them on Friday and used them tonight and they are spectacular. Brilliant views of Saturn and Jupiter.Thanks again." -Fred Milstein

"I had a quick session late last night, using my TMB 115. Saturn was superb, Jupiter was surprisingly good at only 25 degrees above the horizon, and I was easily splitting 1.5 arc second double stars at 150x. Excellent!!!!" -Silvio Jaconelli
