This is an example of a mosaic image created with the GELLER program dPict.  In this case, a Backscattered Electron image of a polished meteorite fragment is shown, but any imaging signal (BSE, SEI,  X-ray) can be used.  The image was created by ‘stitching’ together 49 tiles (7 horizontal, 7 vertical) each acquired at a 40x magnification.  The resulting image has a magnification of 5.7x.  A single 40x raster is show.
