A sighting device for a bow. A light emitting diode (LED) or other initiator of light emits light to form a bright sight point in a line of sight of the bow when the bow is held in a position for shooting, wherein the initiator is spaced from the bright sight point at a position such that it does not obstruct the line of sight of the bow. The initiator is responsive to an indication of an electronic level or other indicator of orientation that the shooting instrument is within a predetermined angle, preferably about 1 degree, of side-wise tilt. Alternatively, a photo optic cable or other light transmitting flexible tubular member has a first end which receives light from a light emitting diode (LED) or other initiator of light and a second end at which the received light is emitted. The second end of the tubular member is positioned to provide the sight point.

What is claimed is: 1. In combination with a shooting instrument, a sighting device comprising a member, an initiator of light to said member for effecting a bright sight point in a line of sight of the shooting instrument when the shooting instrument is hold in a position for shooting, an indicator of orientation of the shooting instrument within a predetermined angle of side-wise tilt about the line of sight, said initiator being responsive Lo an indication of said indicator that the orientation of the shooting instrument is within said predetermined angle of side-wise tilt to effect the bright sight point. 2. The combination according to claim 1 wherein said member is a light transmitting member having a first end for receiving light from said initiator and a second end providing the sight point at which second end the received light is emitted. 3. The combination according to claim 1 wherein said initiator is positioned to emit light onto said member for effecting the bright sight point wherein said initiator is spaced from the bright sight point at a position without obstructing the line of sight of the shooting instrument. 4. The combination according to claim 1 wherein said member is a fluorescent member having an end providing the sight point, and said initiator is spaced from said fluorescent member in position to emit light onto said fluorescent member without obstructing a line of sight of the shooting instrument. 5. A combination according to claim 1 wherein said indicator includes an inclinometer having a fluid therein, the combination further includes means for orienting said inclinometer to provide indications of side-wise tilt when shooting downwardly from a tree stand as well as horizontally. 6. A combination according to claim 1 wherein said predetermined angle is about 1 degree, clockwise or counterclockwise. 7. A combination according to claim 1 wherein the shooting instrument is a bow. 8. A combination according to claim 1 wherein said initiator is a light emitting diode. 9. in combination with a shooting instrument, a sightinq device comprising means for effecting a bright sight point in a line of sight of the shooting instrument when the shooting instrument is held in a position for shooting, said bright sight point effecting means including an initiator of light, and an indicator of orientation of the shooting instrument within a predetermined angle of side-wise tilt about the line of sight, said initiator being responsive to an indication of said indicator that the orientation of the shooting instrument is within said predetermined angle of sidewise tilt to effect the bright sight point. 10. The combination according to claim 9 wherein said initiator is positioned to emit light for effecting the bright sight point wherein said initiator is spaced from the bright sight point at a position without obstructing the line of sight of the shooting instrument. 11. A combination according to claim 9 wherein said indicator includes an inclinometer having a fluid therein, the combination further includes means for orienting said inclinometer to provide indications of side-wise tilt when shooting downwardly from a tree stand as well as horizontally. 12.
