Lumicon 1.25 Inch Minus Violet Filter

Lumicon 1.25 Inch Minus Violet Filter is used primarily to “bracket” the color-corrected band of refracting telescopes. This filter can also be used as a “visible” filter in RGBV (red-green-blue-visible) astrophotography with reflecting telescopes.

Most digital/CCD cameras have built-in infrared filters, however a minus violet filter may be used in addition depending on how far into the blue your primary lens is color-corrected.  This filter blocks wavelengths shorter than about 420nm, reducing halos around objects for photography.  Recommended for use with a telephoto lens to remove chromatic aberration.

Threads into the nosepiece of industry standard 1.25″ digital imagers.
