viewing an object by looking slightly to its side. This technique can help you detect faint objects that are invisible when you stare directly at them.
A technique of looking slightly to the side of a faint object to increase its visibility through a telescopic eyepiece. By looking slightly off to the side its light falls on the part of the retina most sensitive to light.
An observing trick of looking at an object in the eyepiece is to look a little to one side of the target. This "averted vision" places the target on a more light-sensitive area of the eye's retina where it will pop into view.
The observing technique in which you look at an object using the light-sensitive area of the retina offset about 18-degrees from the fovea centralis.
a technique that uses the more light-sensitive rods in the eye to better see a faint object by looking at it indirectly
A method of detecting very faint objects using the sensitive low-light rod cells of your eyes that are located around the sides of your eyes. To see faint objects, don't look straight at them but rather look at them out of the corners of your eyes.
