Design And Application Of Digital Photography Connecting Devices For Telescope

With the people’s living standards improve, the popularity of digital cameras, binoculars, photography enthusiasts with a digital camera with a telephoto telescope easy combination300-1200mm telephoto lens for bird photography observe, long-term perspective shooting, documentary photography, forensic photography, observation and photo-graphed long-range of transport and environmental protection departments have been of great very practical value. This makes the application of telescope, digital photography application and developing prospects very wide.In this text, a small-scale production of the monocular telescope combined with several common household with the binoculars digital camera digital photography as a research object, through the telescope and digital camera connection mode of analysis and research, a set of small single cylinder which links up telescope with90%of digital cameras; As being cheap and adaptable, it will be put into mass production of the coupling device to solve the key problems of digital photography telescope.The main technical parameters being analyzed, connection to the connection device through a telescope and digital camera, telescope being taken, how-matching telescope type, main technical parameters (objective lens diameter, magnification, field of view, resolution Rate, exit pupil distance, etc.), digital camera type, the main technical parameters (focal length, optical zoom, the lens field of view, etc.) offers a choice of method and basis for digital photography amateurs.Photographic image quality through the analysis of detection methods, the three digital photography for the telescope image quality detection method have been described.①The resolution of the collimator and the telescope plate detection system, digital photography,photography comprehensive resolution, and to quantify the results, so that photographers can easily compare and match.②dead pixels and the noise detected by the software.③detecting the accuracy of exposure by histogram, telescope imaging quality digital photography, amount of testing methods and ideas are offered for photography enthusiasts.HaierDC-A30and JIE HE telescope for the test subjects, telescope collimator system integrated digital photography resolution of the testing being detected, a telescope and digital camera combination of the telescope comprehensive resolution of the detection of photographic equipment method being established, for the telescope and digital camera connection when the connection distance on the imaging quality of the testing, which draws connection distance, digital cameras and digital cameras, the focal length to the maximum magnification zoom lens extends the relationship between the maximum distance max, Magnification of the telescope for the telescope image quality of digital photography of the testing, a telescope, digital photography, the telescope magnification being established with a digital camera match the connection of the relevant parameters, being match the aperture and shutter speed test being matched, being built with the image quality test, histogram test exposure, the number of bad points, and noise detection method for comprehensive detection of image quality, from the perspective of a comprehensive quantitative detection of image quality.
