The Digital Camera Adapter places your various point-&-shoot digital cameras close to the eyepiece of your spotting scope. It has a clamp for the eyepiece and various location adjustments so that you get the digital camera centered exactly where it needs to be for the best images with high resolution and no vignetting. As with all digiscoping, it is far easier to align the digital camera's lens with the scope's eyepiece when that eyepiece has a broad, flat rear element-making a bigger target for the camera's vision to fit within.
To describe here exactly which cameras work with this is simply impossible, but for some guidance...the shortest distance between the tripod socket and the center of the eyepiece is approximately 1.26" (32mm), while the longest distance between the center of the eyepiece and the tripod socket is approximately 2.91" (74mm). The tripod socket can be as far as approximately 2.12" (54mm) to either side of the center of the eyepiece, so as long as the distance between your camera's tripod socket and the center of its lens is less than this it should likely fit.
As with all ventures in the world of digiscoping, you'll need to employ good technique and good equipment to get good pictures-which means a sturdy tripod and secondary support for the camera if possible, a sensibly-high shutter speed for the digital camera and as much care as is possible to prohibit camera movement. This should always include the use of the camera's electronic shutter release cable or remote control if the camera has such capacity.
