There is no zooming facility in a compound microscope. A lower power objective doesn't show enough detail. The one used for this picture was a 10/0.25 Leica Fluotar. The image is salicylic acid (salicylate) crystallized from 70% ethanol directly on the slide under a cover slip. The picture was taken using polarized light, a Lomo aplanatic condenser and a Zeiss (Rot) full wave retardation plate. The crystals formed very slowly and that why they are so good looking. Final magnification is about 100X but I haven't checked this yet. The CCD doesn't fit the graticule in the binocular eyepiece (made for 35mm and 4 x 5) so I have to do some arithmetic. These pictures (a selection) will be printed -- big -- framed and offered for sale in the US very shortly. Some will only be printed once -- making them originals.
