Antares 0.5x 1.25" Focal Reducer (FR1)

Antares 0.5x 1.25" Focal Reducer

Focal reducers can be used either visually or photographically to decrease focal length and increase true field at the expense of some vignetting (dimming) at the edge of the field. The reduction depends on the spacing of the reducing lens between the objective and the image plane. The Antares 0.5x 1.25" Focal Reducer is a fully multicoated 25/95mm achromat and fits standard 1.25" filter threads
