Product Info

Manufacturer Description

1.25" Vernonscope Mounted Glass Filters feature 1" clear-aperture optical glass. Numbers are engraved on the mounting to correspond with those of Kodak Wratten series. The mountings are edge-knurled and threaded to fit the bases of BRANDON oculars and DAKIN Barlows. Vernonscope Mounted Glass Filters cut glare, provide superior contrast, improve definition and reduce eye fatigue.


  • Yellow (#12) is useful for observing Mars, especially to highlight light areas or darken blue or brown features.
  • When observing Jupiter, #12 is used to darken blue festoons near the equatorial regions.
  • When used to observe Uranus or Neptune, it enhances the blues and greens of the atmosphere.

Important Note: Brandon filters use a non-standard filter thread that works only with Brandon eyepieces and Dakin barlows. These filters cannot directly be used with other products that use the industry standard 1.25" filter thread (M28.5x0.6). An optional adapter (part # 114ADAPTVERN) is sold separately that allows you to use this filter on other accessories with standard 1.25" filter threads.
