Hi Brad

Alpen does not offer a dedicated adapter for an SLR like your Canon. Sorry.

Only option is a universal adpater, such as the Alpen 706 or the [urlhttp://www.opticsplanet.net/nikon-universal-mounting-bracket.html]Nikon[/url] (better for the weight of an SLR than the Alpen) to mount your camera, equipped with a short focal length (50mm or so) lens, behind the eyepiece of the spotting scope. This is less than ideal, since a large camera lens on an SLR produces a lot of vignetting (darkening at the edge of the field) and the size and weight of your SLR makes for a heavy, unwieldy package.

You can get an idea of the results with this setup before spending money on an adapter simply by handholding your Canon (with a short lens) over the eyepiece. All the adapter does is hold the camera for you.

A much better option is a SMALL digital point and shoot with no more than 3x or 4x optical zoom. Small camera lenses are a much better match for a spotting scope eyepiece. You may already have one of these. If so, give it a try, same as above.

Good questions.
