Here are some reviews that have been done on the Siebert Optics eyepieces showing their advanced optical design Click here, here, here, here, here and here
****All Siebert 5 element Orthos have 60+ deg FOV and 10mm ER*****
New Brass Orthos available >Click>
Shown here is the 4.9mm Siebert Modified Ortho with a 13mm eye lens. Compare to an HD 9mm Ortho with a 6mm eye lens that is lens 3.5x the lens area.. Hence the extra ER and FOV. These use a blend of Fully Coated and Multi Coated optics to maximize transmission.
