This 2" 48mm Vernonscope Brandon eyepiece seems to disappear in your telescope, like looking at the sky with your bare eye, only with everything larger and sharper, as if the telescope and eyepiece didn't exist . . .
Our Product #: VB48

Product Description

The 2" 48mm Vernonscope Brandon eyepiece is designed for nigh-perfect low power deep sky observing with any telescope type that can use 2" eyepieces, at focal ratios of f/7 and above. With shorter focal length telescopes, the exit pupil will become larger than your dark-adapted eye's pupil, wasting some of your scope's light-gathering capability.

Emission and reflection nebulas, planetary nebulas, globular clusters, open clusters - all look superb against the dark sky background of the tack-sharp, high contrast, 48mm Brandon. Observers typically comment that the 48mm Vernonscope Brandon seems to make their telescopes disappear. They say that looking through the Brandon is like looking at the sky with your bare eye, only with everything larger and sharper, as if the telescope and eyepiece didn't exist.

Eye relief is very long, at 40mm, allowing titaslly unvignetted use with eyeglasses. There is no rubber eyeguard, so keeping your eye centered on the exit pupil to prevent momentary blackouts can be a minor issue until you become familiar with the eyepiece.

The best of the long focal length eyepieces! The background sky is velvety black, the stars absolutely pin point, across the field - superb contrast - and virtually all of the Double Cluster in Perseus in one field with my 260 mm f/11.5 catadioptric scope. The long eye relief is not a hassle for me - the image is easily located and maintained. I had nonetheless tried a couple of eyecups; they are not necessary and are in fact a bit of annoyance when removing or replacing the protective cover on the eye end of the Brandon. This eyepiece is an additional $100 more than premium examples of similar focal length from other makers - worth every penny. (Posted on 1/21/2020)

I purchased this eyepiece for use with my 6" f/12 apo refractor in an attempt to get the widest view possible given the long focal length of this instrument, and for this use it excels. I can easily frame larger objects such as the double-cluster in Perseus, and the view is tremendous! Pinpoint stars across the entire field, and essentially none of the barrel distortion that I find objectionable in many of the newer wide-angle designs. While the extreme eye relief does take a little getting used to, one beneficial side effect is that this is the most comfortable eyepiece I've ever used when wearing glasses. I can easily see the entire field of view and the lens of my glasses is nowhere near touching the eyepiece. Despite its modest apparent field, this eyepiece essentially disappears in use and gives one an experience of the vastness of space that few others do. The contrast is awesome and star images are amazingly sharp. I've also used this eyepiece in my 90mm f/7 apo, and the views were equally impressive, with only slightly worse edge performance. This is one fantastic eyepiece! (Posted on 8/4/2017)

The first time I used this magnificent piece of glass was in my big SCT at a dark site. I sent the scope to M22, the spectacular globular cluster in the southern summer skies, and popped in the 48 and focused and . . . well, there was simply no way to even estimate the total number of pinpoint stars! Brandons have a reputation as the clearest and most precise members of the vast eyepiece herd for a reason. The 48 is simply exquisite for viewing broad expanses of sky in slower scopes, although its performance is said to drop off some at focal ratios faster than about f6. I always use it to dazzle visitors at public outreach events. It is that good. (Posted on 8/4/2017)
