<p>[QUOTE=&quot;desertgem, post: 1376323, member: 15199&quot;]I wish I could say I have been impressed with any usb microscopes. I bought one when they came out, but I don&#039;t use it for reasons given above, coverage area, lighting, most have lenses made of plastic, some use the lens cover ( plastic) as a 0.5x accessory lens to try to increase the coverage area, and especially the low resolution, 1.3, 3, or maybe at the best 5 mp. Not very usable for cropping and enlargement. A microscope should be a life time investment and it will cost some money. You may have young eyes now, but in 40 years, you will be happy you bought a professional binocular zoom microscope, as you may even read the small print with it by then <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie9" alt=":eek:" unselectable="on" unselectable="on" />. I have use microscopes professionally before retiring for 40 years, compound scopes with or without USB cams, dissecting scopes, TEM and SEM electron scopes, and I have poor eyesight from birth and not getting better. Watch for surplus sales of lab scopes, or find some companies that sell new scopes to universities and take in their solid old AO, B&amp;L, etc. You will think you might rather buy a very nice coin, but if this is going to be a life time hobby, you won&#039;t regret the investment.</p><p><br /></p><p>I used for 30 years ( and it was surplus then) a&nbsp; B &amp; L stereozoom that goes from 0.7 to 3.0 magnification. With a pair of 10 X eyepieces, that gives 7x-30x continuous. I also have a pair of 5x eyepieces which produces ( 3.5X-15X) and 2.5X eyepieces ( 1.75-7.5X ), so I can cover the complete range. I use an old Canon 590IS digital camera to take photos through the eyepieces. The IS stands for image stabilization, and it does help with getting sharp photos. If you are naturally shakey, they have camera holders for eyepieces that are used for astronomy, but work well. The camera can handle slab photos, etc with the macro setting.</p><p><br /></p><p>Too often we see photos where we can&#039;t blame the person as they are doing the best they can with the equipment they have, and they spend less than a hundred $, hoping they can take full photos of their Morgans and they can&#039;t. There are no cheap wonders in optics, you get what you paid for. IMO.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
