Here is an image of one of the best formed lava flows on the Moon. It is located between Carlini and McDonald in Mare Imbrium. I have combined it with my own image in saturated colour, as well as with a Clementine Ratios image. My saturated image is in visible light. The Clementine composite uses 11 filters to produce the image, hence the different colours (eg. extra UV data not present in my image). KC Pau is the only other amateur who has imaged this feature in detail.
