Bottom Field Stops Flat Black and Baffled.
Astronomers have known for years that the best views of planets and close doubles are to be had with clear skies, a good 'scope and the proper eyepieces for the job.
For most that has meant Orthoscopics and Monocentrics. The idea is to ensure the best contrast and least scatter so critical for planetary viewing. To make this possible you must use good glass, high polish, and the fewest air/glass surfaces possible. As good as Orthos and Monocentrics are, however and they may have certain advantages, they still have 3 or more elements within them. The Logical solution...... a spherical singlet lens. No multiple elements to reduce sharpness and contrast. On axis, these special lenses produce the sharpest images of planetary detail available anywhere....Period.
Siebert Optics is proud of the Planesphere ID family of Eyepieces. Call today to discover how Siebert Optics and Planesphere can enhance your viewing experience. Planesphere: The last word in critical viewing.
