Abstract
A filter or lens for a star tracking telescope includes a clear center portion and an attenuating peripheral portion where the peripheral portion attenuation of off-axis images is nonidentical through any radial line extending from a center of the filter or lens to a circumference edge of the filter or lens for passing on-axis images with high signal to noise ratios and for attenuating off-axis images for attenuating but not completely blocking the off-axis images, which telescope with such a filter or lens is well suited for improved star tracking systems, and well suited for reducing off-axis glare in handheld optical apparatus such as binoculars, telescopes, cameras, and eyeglasses.
