| 20090040600 | Telescope Adapter for Supporting a Camera - A telescope adapter for supporting a camera includes a light beam splitter for receiving light from the telescope and dividing that light into a monitoring bundle of light rays and a recording bundle of light rays, the two bundles of light rays being at angle to each other. The user is permitted to view the monitoring bundle of light rays, and the adapter can support a camera in a position to receive the recording bundle of light rays, so that the user and the camera can receive light from the telescope simultaneously. A first lens system is located between the telescope and the light beam splitter, the first lens system having a total negative power. A monitoring lens system receives and transmits the monitoring bundle of light rays leaving the light beam splitter, and a recording lens system receives and transmits the recording bundle of light rays leaving the beam slitter, both the monitoring and recording lens systems having total positive power. A reflective prism receives the recording bundle of light rays leaving the recording lens system and reflects those light rays toward the camera along a path substantially parallel to the monitoring bundle of light rays. | 02-12-2009 |
