The National Optical & Scientific Instruments DC3-420TH Stereo Zoom Microscope with Built-In Camera provides a live view of specimens with the built-in analog/digital CCD camera. The included Motic Images 2.0ML software also allows the user to capture, label, manipulate, and measure images. In addition, the DC3-420TH can also be used independently of the camera.

The optical system of the microscope centers around 1-4x objectives, which allow for continuous 10-40x magnification. The paired widefield 10x eyepieces provide an upright, unreversed three dimensional image as well. Illumination for the 420TH is provided by top and bottom halogen lights. A blue filter is built-in for transmitted light.

The base of the microscope includes a sturdy stage that accepts the two included 80mm stage plates: one in frosted glass and a reversible black/white plastic contrast plate. Two locked-on stage clips work to prevent slides from moving, while the post mount with locking collar permits up or down adjustment for objects of varying size on the stage.

Quality shoe but with a slight squeak.
Size: 10 Wide, Color: Burgundy Polished Full Grain
Nice shoes with the classic Penny Loafer design. Fit was better than another brand I tried. Only reason not 5 starts is disappointment due to a slight squeak at times when walking.

Exact item ordered, quick delivery
Size: 9.5, Color: Black Polished Full Grain
I ordered these black Cole Haan penny loafers for casual wear with jeans, khakies, and even business casual with slacks and a jacket. They've always worked perfectly for these uses. The Cole Haan version is the most versatile and still meets my sophisticated look criteria. I wear a 9 1/2 M with almost all other shoes. I have found Cole Haan to run slightly wider and slightly shorter. This fit will work with thin and no socks and a little loose in width. . I'd likely order a 10 N next time. I tend to forget this but it runs consistent with me for Cole Haan. 5 stars for the shoe and service. My bad on the slightly off fit.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.
