| I bought a Celestron digital microscope in late December 2011. It has an LCD display that supports touch-screen control. You can take photos/videos of the LCD image that can be stored on a SD card or internal memory (1G). It has a USB interface to read out memory. I also bought a 100-slide collection of specimens. Below I show some photos of a few of the slide specimens, a slide (onion root tips) that Linda had prepared 36 years ago, a dead wasp I found and other odds and ends. For the price, the scope is pretty powerful and straightforward to use. | ||||||||||||||||||||||

| Some Comments on the Photography:
For many of the photos, the entire speciment is not in view at the lowest power (40X on the LCD). In some of those cases I moved the stage to one position, took and photo, moved again, took another photo and then used the photomerge option in Photoshop to merge the photos. In some of the cases (like the wasp) the narrow depth of field of the field does not allow all parts of the specimen to be in focus. In that case I took a number of photos, focusing on different parts of the specimen and then used the Helicon application to produce a single all-in-focus image. For some of the photos I did the extended depth-of-field technique at each stage position and then merged the resulting images from the Helicon app using Photoshop. Scroll down this page for some of the photos and click on the links for even more photos: |

of Adobe Photoshop to stitch the photos together. |

| Above left: is a down feather. I just had this on a slide with no slip cover so the entire feather was not in the same plane - hence focusing a problem. I took nine photos, changing the focus for each one, and then used the Helicon app to merge into a single photo. Above right: protozoan paramecium. You can certainly make out the macronuclei.
