Special Attention To Detail For Real Gains
We have deisgned the BIG EASY prism coatings to peak in the H-a bandpass. What does this mean? The peak transmission is centered around the 656nm bandpass. So, while our coatings average 0.2% reflectivity across the visible spectrum, the transmission peaks in H-a at better than 99.8%! Naturally, the increased contrast of BIG EASY coatings mean great nightime views will be the result as well. Over and over again, customers all over the world rave about the performance of the BIG EASY.
The Denk II Binoviewer With SCD Holders
As with all of our binoviewers, this model is assembled in our Maryland, U.S.A. facility and undergoes meticulous quality control measures all along the way. We hand collimate each and every unit and check the diopters for motion and feel. Our internal lubricant is rated for smooth motion from +120 to -40 degrees Farenheit so those customers in Norway, Canada, Alaska, Sweden and all points north need not worry about locking up. The same can be stated about the interpupillary (IP) motion when being used in cold weather . Our denk Binoviewers will fold and unfold easily in any temperature to accomodate the widest range of ocular width in the industry (49mm-75mm: Custom accomodations can be integrated to obtain even wider IP seperation).
The photo above shows the SCD Holders. Notice that they are set at different heights. The allow individual eyepiece focus to be accomplished smoothly and with great accuracy. We spent many months designing and testing the threads until we got it right! The SCDs are extremely well recieved by customers all arounf the world. The special internal threads allow focus change at a very nice speed. What we mean by this is that focus changes are easy to detect but not too slow or fast. Merges is maintaned because the machining of the SCD holders is specified at very high tolerances. The top ring (black) locks the eyepiece in the holder by collapsing an internal split ring. After this is done, the silver lower ring may be used to change focus in either eyepiece. These holders are made from quality aluminum material and then clear anodized and black anodized. These are not plastic!
All of our binoviewers will accept any Denkmeier accessory that we make. If you are purchasing a Denk Power x Switch Star Diagonal and are deciding on a model of Binoviewer, this is a very economical choice. No Power x Switch or Optical Corrector System is needed in that situation. Just load this Denk II Binoviewer with SCDs in the diagonal and you are ready to Power Switch. See our Star Diagonal section for more information.
World Class Performance
When deciding whether to get your feet wet or not, it may be tempting to purchase a small prism binoviewer just to test the waters. The first binoviewer in our Ala Carte Section has 26mm clear aperture Denkmeier Prisms. A system like The Big Easy focuses at two magnification modes in Newtonians, Refractors and three magnfication modes in SCTs including focal reduction. So, those who compare apples to apples should arrive at one conclusion: A Denkmeier Binoviewer is available for anyone ready to view The Universe's greatest natural wonders with two eyes! The BIG EASY always includes a Denk case and SCD Holders along with both a 1.25" and 2" nosepiece. It is our Premium Binoviewer. If you are planning on purchasing one of our Power x Switch Star diagonals, this is a great choice if ultra-refined performance is what you must have even if it means that there is a higher price point.
