What is EAA?
Electronically Assisted Astronomy (EAA) is defined as the use of an analog or digital image capturing device in lieu of an eyepiece at the telescope. It is thus similar to visual observation but uses cameras and computers instead of the naked eye.
EAA in Practice
Some observers alternate between visual (eyepiece) observing and EAA or between astrophotography and EAA. Just because a person employs EAA, it obviously doesn’t restrict that user from other forms of the hobby of amateur astronomy.
