I enjoy using them on my 6"F/10 refracting telescope.Brandon is a brand name of VernonScope, and is applied to a variety of products, including a well-established line of eyepieces. Several of the short- to medium focal-length Brandon eyepieces are advertised as orthoscopics, yet they appear upon disassembly to resemble Plossls. They use four lenses in an unsymmetrical duplet formulation designed by Chester Brandon, one of the designers of the top-secret Norden bombsight, which played an important role in World War II.
