Abstract: A variable photo-visual telescope filter that consists of filter disc (24 and FIG. 5), mounted in a protective housing (FIG. 4). The photo-visual filter is sandwiched between a telescope eyepiece at one end (Prior Art 10) and a telescope eyepiece holder (Prior Art 14) at the back of a telescope. The filter disc consists of a hard, clear material, imbedded with colors. The colors are concentrically arranged on the filter disc (24). The filter housing has an indicator window (22), which shows an abbreviation of the color being filtered (30). Filter colors are varied be slowly turning a rotary knob (18) which is attached to the filter disc (24). The rotary knob turns the enclosed filter, independent of the filter housing.
