<p>[QUOTE=&quot;desertgem, post: 914249, member: 15199&quot;]My background is a little different after having been in Microbiology for decades and using almost every kind of magnifying device except acoustic and other advanced kind, but have used SEM and TEMs. </p><p><br /></p><p>I use a stereo microscope with a zoom ( .7-3.0 ) which with various eyepieces can give me magnification from 1.75X&nbsp; to 60X.&nbsp; It is not so much the magnification, as it is the control of focus, the ability to set up and keep a consistent lighting, both dead on, and edge, and stability of the coin position when photographing.&nbsp; The camera can either be part of a stereo microscope, or one can shoot through the eyepiece very well with even a point and shoot digital camera. If I shoot a photo and upon resizing it in the computer, I notice a glare, I can replace it on the scope and it is basically the same image and I can make the small alteration to remove the problem. With a good stereo microscope, one lens usually is an adjustable diopter, so with a setup of that feature, I can use the scope without my bifocals, and it is so much more comfortable. </p><p><br /></p><p>In searching through coins, I can put a number on a flat surface carrier ( small square of white plastic) and quickly move from one coin to another.</p><p><br /></p><p>Kudos to those who can use a loupe effectively and quickly, and can hold their breath so they don&#039;t spray invisible secretions on a coin, but as the gun people say, you will have to&nbsp; pry my stereoscope away from my cold dead hands <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
