Starguide - A Practical Guide to Astro-Photography

EAA, or Electronically Assisted Astronomy, is a wonderful tool that allows you to see things that would otherwise be hidden from view. With EAA, you can explore the beauty of the universe in a whole new way, far beyond what you could see with just an eyepiece. It's the perfect complement to purely visual observing, and it's great for stargazers who might not have the visual acuity or patience to look through an eyepiece.

EAA stands for the ability to observe celestial objects without using eyepieces. Instead, you can use electronic cameras, such as digital single-lens reflex (DSLM) cameras or special astro cameras. These instrument use computer programs to track (called Tracking) or follow objects (called Guiding). They also compensate for the design limitations of mounts. This allows them to achieve very long exposure times. These exposure times would not be possible without these electronic aids.
