This 1.25in filter consists of two joined polarized filters that
provide continuously from about
2% to 40% as the rotating filter is adjusted. Great for lunar
viewing without ruining your dark adaptation from staring
at a bright image. Adjusting the filter brings out the best
contrast in the area of interest. Standard filter threads
screw onto 1.25in eyepieces.
The two sections of the filter can be
unscrewed, and now you have two separate polarising filters.
Polarising filters can be used to increase contrast in some
images, and can be especially useful for daytime photography.
A good way to use the filters for lunar viewing: Screw one of the two sections onto your 1.25in diagonal nosepiece, and
screw the other section onto your 1.25in eyepiece. Now the
attenuation can be adjusted by rotating the eyepiece. No need
to remove the eyepiece to adjust the filter!
