Top DSLR for astrophotography
|
There are four basic kinds of digital camera available for purchase today: the digital SLR camera, the CCD, the digital snapshot camera, and the webcam. In this article, you’ll learn how each can improve your astrophotography. *The digital single lens reflex camera (DSLR) has a removable lens that has a variety of focal lengths, from a “fish eye” to a telephoto. These cameras offer a high level of control over factors such as shutter speed, ISO and aperture. They have digital sensors, and their lenses are able to be removed and the area fitted with an adapter that allows for connection to a telescope that acts as the camera’s lens. *An astronomical CCD camera is cooled in order to cut down on noise, and are made for scientific photography purposes by various companies. They are made for use with a telescope, but adapters are available that allow for them to be used with conventional camera lenses for a wider angle. These cameras need a computer for use. *Digital snapshot cameras have fixed lenses and a low maximum exposure. A DSC camera can be used for scenic astrophotography, but they do not work so well for deep-sky photos or a longer exposure. *Webcams are typically inexpensive, coming with either a CMOS or a CCD chip that enables them to stream Web video. The chips are small, with very high-resolution pixels that shoot a continuous video. These work great for high-res planetary shots, but not so well for deep-sky shots. If you already own a digital camera, that’s fine to get started. Even if you do not have a telescope or any other kind of equipment, you can still snap photos of constellations, star trails, and the moon. If you’re buying a camera for astrophotography, ask yourself what kind of pictures you will be taking, what is the best kind of camera for your needs, and how involved you want to become. The answers to those three questions, along with your budget, will play a large role in determining what kind of camera you get. | |
