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.
Antares FR1 is a fully multicoated 25/95mm achromat and fits standard 1.25" filter threads.
Antares FR2-0.5 X is a fully multicoated 41/158mm achromat and fits standard 2" filter threads.
