Public access to professional astronomical plates (DSS) has provided a rich source of very deep monochromatic images which can be brought to life using an assortment of digital techniques such as synthesized color layering, image stitching to expand the field of view, and filtering to remove noise and dust artifacts.  The color images below were rendered by synthesizing a green layer from plates taken with red (~600 nm) and blue (~400 nm) filters and then blending the three together using the RGB color model.
