Starguide - A Practical Guide to Astro-Photography

EAA or Electronically Assisted Astronomy allows you to see what would otherwise not be possible to see using an eyepiece alone. It’s an ideal way to complement purely visual observing, and it’s perfect for stargazers who don’t have the visual acuity or patience to look through an eyepiece.

Electronically Assisted Astronomy (EAA) refers to the possibility of observing celestial objects not through eyepieces, but with electronic cameras (today mostly CMOS-based digital single-lens reflex cameras (DSLR) or special astro cameras with additional tracking support by control programs (electronic guides), in order to compensate for design disadvantages of the mounts and thus to achieve very long exposure times that would not be possible without these electronic aids.
