Brandon eyepieces are noted for their exceptional contrast and extremely dark background, two reasons why Questar Corporation has been including them with their telescopes since 1971. All Brandon eyepieces are parfocal. In a test of many eyepieces, noted deep-sky observer, Ron Morales, rated Brandon eyepieces #1 for contrast, which is the single most important characteristic for any eyepiece. The Brandons are fully coated, but not multicoated. In fact, not using multi-coating eliminates or greatly reduces the phenomenon known as narrow angle light scatter. Multi-coatings have more narrow angle light scatter than standard eyepiece coatings. This effect readily can be seen when viewing bright objects like Venus, Mars, or Jupiter, where this scatter greatly interferes with low-contrast detail. Using Brandon eyepieces, you also will notice a significant difference in the background darkness immediately surrounding a bright object, especially important for planetary or double-star observing. In addition, lunar detail such as the bands of Aristarchus are much better defined. They are also excellent for observing solar spots. If you own a telescope with a focal ratio greater than F/7, such as a Maksutov-Cassegrain, Schmidt-Cassegrain or long focal refractor or Newtonian reflector, no eyepiece will give you better performance. All Brandon eyepieces are assembled and tested in Raleigh, NC, to assure consistent high quality. They are the only eyepieces still being made in North America. This set contains the 6mm, 8mm, 12mm, 16mm, 24mm and 32mm eyepieces in a wooden case. Available in flat-top or standard version.
