Product Info

Manufacturer Description

Brandon eyepieces, made by Vernonscope in the USA, 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.

The famous Brandon oculars incorporate the original optical designs of Chester Brandon and are acclaimed by leading astronomers as unquestionably the finest oculars in the world.  In a test of many eyepieces, noted deep-sky observer, Ron Morales, rated Brandon eyepieces #1 for contrast which is perhaps the single most important characteristic for any eyepiece.

Some question why Brandon lenses are not multi-coated. In the past, several sets of Brandons were made with 7-layer multi-coatings with no improvement. 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 Vernonscope's 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.

All Brandon eyepieces are assembled and tested in Raleigh, NC, to assure consistent high quality.

Leave the world of ordinary eyepieces behind and step up to Brandons!

Please note: Brandon eyepieces are threaded for filters, but Brandon uses a proprietary filter thread and not the industry-standard M28.5x0.6 filter thread. Brandon sells 1.25" color and neutral density (ND) filters that can be directly threaded to Brandon eyepieces. However, the use of other non-Brandon filters on these eyepieces requires the purchase of an optional thread conversion adapter.

      5.0 Brandon 12mm




      This 12mm is yet another example of a fine lunar and planetary eyepiece that is truly a joy to use. The day I received it I used it to see the Red Spot and shadow of a moon on Jupiter and extreme detail on a night of near perfect seeing conditions for viewing the Moon. The very first Brandon eyepiece I got was about 1972 and it was a 12mm. I have used Brandons continuously since then and am now putting together a set of new ones. Used on my Celestron SCTs and Tele Vue refractors, these are great for accurate color, resolution, contrast and fine sharpness throughout the field of view. I'm not concerned with having an apparent field of view of 85 degrees, and truly like the light weight of these eyepieces. There is a relaxed ease using Brandons in my experience. They seem to disappear and let you get lost in the viewing and forget about the equipment in front of you. Lastly, they have been and are very consistent in quality. I will continue to use them and enjoy them. You may wish to try them, too.
