Here are a pair of images. The first one is an old scanned slide (non stacked) from my presentation on the Arkansas syenites. The second image is a portion of the same specimen. Still hard to image, but I think the new one is considerably better. FOV is about .4 X .5 mm. These betafites were fairly common in interior pegmatites at 3M, but always as tiny crystals. They are rare in secondary pegmatites. New image with a Canon 40D, 23 mm Nikon objective in a tube configuration with a 300mm Canon FD telephoto. Stacked using Combine Z software
