The Bushnell Universal Digiscoping Adapter places your various point-&-shoot digital cameras close to the eyepiece of your spotting scope so that you can capture high resolution images, free from vignetting, directly through your scope. It has a clamping ring with 3 tension screws for affixing to either the eyepiece or the scope body itself, which can be beneficial for scopes with somewhat delicate eyepiece assemblies. Unlike most of these devices, the Bushnell Digiscoping Adapter quickly allows the camera to swing away for observation purposes and then returns right to the ideal point for imaging as soon as you need it.
Aligning camera and eyepiece is easier when the eyepiece has a broad, flat rear element that presents a wide target for the camera's vision to fit within. And longer eye relief upon the eyepiece facilitates placing the digital camera further behind it so that you can use more of the camera's zoom function to magnify portions of the scope's view.
