AES Annual Exhibition
Saturday 12th October 2019
As a contribution to the Quekett’s outreach programme, Dennis Fullwood and Alan Wood manned a stand at the Annual Exhibition and Trade Fair organised by the Amateur Entomologists’ Society at Kempton Park Racecourse in Middlesex, promoting microscopes and microscopy to young and old entomologists. There were lots of stands spread over 2 floors.
We had lots of visitors to our stand, with all sorts of questions about using microscopes, buying microscopes, and taking photographs through microscopes. We hope to see some of the visitors again at Microscopium (Saturday 19th October, St Albans). Visiting Quekett members included Sam Christofi, Martin Hinchcliffe and Andy King.

Dennis Fullwood brought his trinocular Nikon Labophot compound microscope with lots of slides of whole insects and parts of insects by several famous makers including Richard Suter, Amos Topping, J. B. Howard, H. W. H. Darlaston and Frederic Enock.

Dennis showed several visitors an easy way to take photomicrographs, using a Canon EOS M body, an adapter to take Nikon lenses, a Nikon 50 mm f/1.8 standard lens, a 52-28 mm step-down adapter, and a Leitz Periplan eyepiece that has a 28 mm thread (intended for a screw-on eye cup). The Periplan eyepiece (with the lens and camera attached) is inserted instead of one of the Nikon binocular eyepieces.
Dennis also brought a Chinese inspection camera to display insects in Baltic amber (40 million years old) on a monitor.

Dennis also brought his trinocular Olympus SZ4045 stereomicroscope, and Alan Wood used it to demonstrate a simple system for shadowless illumination using an LED ring-light shining up into an inverted kitchen bowl with its base removed. This setup provides clear images of insects and also worked very well with an insect in amber.

Some visitors were fascinated by this, so Alan took it apart to show the paper tube that stops direct light from the LEDs entering the microscope (or camera) lens, the white bowl that reflects diffused light from the LEDs onto the paper tube, and the white baffle that reflects light down onto the top of the specimen and reduces stray light entering the microscope (or camera) lens.
There were not many microscopes on other stands, but the Natural History Museum had a Leica EZ4 stereomicroscope, the AES had a couple of simple stereomicroscopes, one young exhibitor had a simple stereomicroscope, and the One Stop Nature Shop was selling some microscopes.

There were also stands selling pot plants suitable for rearing various insects.
