With the various conversations regarding comparative aspects of optics I am seeking a way of photographing what a user would see through each of several scopes. First off, if someone knows of a test that has already been done, please respond- I have no desire to reinvent something already done. I have made tubing to place the camera lens at the eye relief point of the scope and block out light coming to the camera other than through the scope. But there are a few problems. One is that even on manual mode nature of the camera distorts the results in both clarity and brightness. Thoughts??
