  First imaging results are obtained with a new CCD mosaic prototype (3K x 3k,
15 \mu m pixels). The CCDs are aligned using an etched socket alignment
technique. Three different measurements of the alignment are made using star
images, test p attern images, and microscope analysis. The CCDs have an angular
misalignement o f less than 30 ppm. The composite device is flat to within \pm
3 \mu m, with rows/columns oriented to within 20 ppm. The use of an existing
technology with built in precision reduces many of the difficulties and
expenses typically encountered with mosaic detector construction. A new camera
being built for the UBC liquid mirror telescope is al so described.
