The Vernonscope 8mm Flat Top Brandon Eyepiece is excellent when used with optical tubes with slower focal ratios (f/7 or higher) because they provide high contrast views of planets. However, it can also be used with faster focal ratio telescopes as well.
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.
