What is the collimation method?
The method of taking photographs through a digital camera that is attached to the eyepiece of a spotting scope is called the collimation menthod. Collimate means the aligning of the optical axis of the optical system. Usually, we look through a telescope/spotting scope through the eyepiece with our eye. When the human eye is replaced by a digital camera to look through the eyepiece to take a photograph, it is called the collimation method.
