Astrophotographers use it for long time-frame shooting as an object is tracked across the sky. They put it through a stacking program which edits out noisy and distorted shots and combines the good ones to show the most detail. Yes, although pictures of the moon and Milky Way can be done with just a camera and the right lens. The biggest expense in astrophotography is the mount. People who make these beautiful pictures of nebulas and galaxies use very precise mounts which track the object to a very fine degree. Good pictures can be made with middling priced telescopes (depending on the type) and a DSLR camera. It's the mounts that make the difference. Beginner quality ones start around $600-700 and then run upwards into the thousands. Some as high as $15,000. Then there's guiding scopes, power tanks, heat tape and blankets, software, and other accoutrements which can quickly make it expensive. I would like to get into astrophotography but I want to do it right, which places it really low on the justification vs expense factor on the priority meter. |
