Antares Light Pollution Rejection - Nebula
'Deep Sky' filter - 1.25" and 2" sizes
This broadband dieletric filter improves contrast and visibility of
emission nebula by greatly reducing the effects of light pollution.
Also great for general viewing from light polluted locations. Very
similar to a "deep sky" filter, attenuates light from mercury and
sodium lights and natural sky glow, while passing the important
lines of the visible spectrum. Specification details below. Don't
be fooled by the price, these premium filters compare very well
to the big names. Standard 1.25" or 2" threads fit eyepieces and
diagonals.
