I am completely new to metal engraving and so, may ask very ignorant questions. I followed the advise found here on EC and bought one of the "acceptable" stereo microscopes, a Nikon SMZ1 with a 0.4 objective and, I believe 10x eyepieces. However, the field of view is tiny! Looking through the eyepieces, the view appears about the size of a dime, in the distance. A US penny fills the entire field of view, about 2-3" away. What am I doing wrong? Please, someone help me get this set up or at least get me started on the right path!
