The 8mm Vernonscope Brandon eyepiece is designed for use with telescope focal ratios of f/7 or slower. This provides very high contrast and detailed views of planets and star systems. It will also work quite well with fast focal ratios as well. Without the eyecup the eyerelief of the 8mm Vernonscope eyepiece is at 6mm but is reduced slightly when using the rubber eyecup. However, most of the objects are small observed at this magnification, therefore this isn't really an issue.
- Sharpest design for high magnification
- 8mm focal length
- 43° Apparent field of view
- Rubber eyecup included
- 1.25" barrel size
The Brandon parfocal eyepiece design is known for their high contrast and dark background, which have made them a very popular design since 1971. The design was praised and rated #1 by deep sky observer Ron Morales for the remarkable contrast. There are no multi-coatings in Vernonscope Brandon lenses to prevent light scatter which would hinder resolution and contrast.
All Brandon eyepieces are tested in Raleigh, NC.
