How does the result compare to the image of the sample viewed through the digital microscope and the eyepiece separately?
In principle, the images are the same. There may be differences in the field of view depending on the type of digital camera and eyepiece we are discussing. However, there is one important difference: viewing your sample with the binocular eyepieces of a stereo microscope will give you depths that a digital microscope's 2D image can't reach.
