What are astrophotographic binoculars?
Astrophotographic telescopes are binoculars that are designed to be used with cameras. The telescope of this design allows professionals and fans to capture images of distant objects such as the Moon and Nebula. Some telescopes are specially built for space photography, while others are designed for general observations, but are adapted for astrophotography using camera adapters. In 1850, William Bond and John Whipple became the first people to photograph the star. Astrophotography has spread rapidly during the end of the 19th century, and many astronomers used simple refractive telescopes to capture images of many different space objects. Astrophotographic binoculars used by amateurs are usually divided into two groups based on the intended use. The first group of binoculars is INTSKONCEL for a high -resolution photo, while the second group of range is designed for "wide fields" of images. This allows the telescope to focus a small area of light into a sharp OBRazu. High -focus tescops with long focal lengths are best for photographing images of surrounding space objects, including the Moon, Mars, Saturn and Jupiter.
Astrophotographic telescopes designed for wide field images have very short focal lengths and large holes. These properties allow you to capture very weak and remote light sources. The wide field binoculars are not as fresh or clear as high -resolution units. Astrophotography of wide fields are suitable for making pictures of objects far from Earth, such as nebulae, star clusters and galaxies.
Mount or tripod we are Myed to ensure the astrophotographic telescope is as important as the optics of the extent. Space objects can be more than a hundred thousand kilometers from the ground and shooting weak objects requires a very long time of camera exposure. During an image exposureEven a small amount of movement in the telescope can cause blurring the final photography. High -quality handles for astrophotographic telescopes allow the range to be held in the correct position without undesirable sagging or fluctuations.
The movement of the earth and other celestial objects can make astrophotography very demanding. Some astrophotographic telescopes are mounted on special tripods that compensate for these natural movements. Advanced imaging telescopes use engines to monitor the movement of the cosmic object and allow a long exposure time of photography without blur.
