Abstract: An optical observation instrument has a device (1) for protecting against incoming flare (40) arranged within the beam path of the instrument. The device contains a filter (22/30) tuned to the flare (40). The filter (22/30) is configured and arranged within the beam path such that the flare (40) transits the filter (22/30) at least two times.

Abstract: An illumination apparatus for a telescopic sight has a lamp, in particular for a reticle of the telescopic sight. The apparatus comprises a control circuit for supplying the lamp, and an adjustment knob cooperating with the control unit for adjusting the brightness of the lamp. Incremental markings are associated with the adjustment knob. The control unit is provided with first means for scanning the incremental markings when the adjustment knob is operated, second means for generating incremental signals, and third means for generating from the incremental signals a signal for controlling the brightness of the lamp.

Abstract: A holding device holds a camera rearward of an ocular of a glass such as a monocular or binocular to record an image utilizing the camera. The image is made available by the glass. This holding arrangement is usable with many cameras and binoculars or monoculars. A rapid change between the camera positioned forward of the ocular and a cleared ocular is made possible for the direct viewing by the user through the glass (binocular or monocular).

Abstract: An optical observation instrument has a device (1) for protecting against incoming flare (40) arranged within the beam path of the instrument. The device comprises a filter (22/80) tuned to the flare (40). The filter (22/30) is configured and arranged within the beam path such that the flare (40) transits the filter (22/30) at least two times.

Abstract: A stand adapter for a telescope and a binocular telescope are disclosed. The stand adapter comprises a support surface for the telescope and a band for securing the telescope on the support surface. The support surface is at least partially configured arc-shaped, such that with a binocular telescope the barrels of the telescope rest on arcuate sections of the support surface.
