Golden Fractures

image by Sergio Alonso (Zerjillo) and Antonio Román, Chirivel, Spain

Zerjillo & Antonio are two long time friends in Granda, Spain who have become very serious about observing and astrophotography. In a series of entertaining and instructive videos they show how they have built a small obervatory, created an Obsession Rover to transport their 25" telescope, and made the best mirror cover I've ever seen. They also image the Moon, acquiring some wonderful shots that hopefully portend many more excellent ones to come. I like this view of Hyginus because the golden glow reminds me of evocative images from the past, and because Hyginus is simply one of the most fascinating fractured areas on the Moon. Seeing the northern part of the Triesnecker Rilles without the distraction of the crater allows the different structural trends to emerge. From Hyginus crater to the west there are faint rille segments that continue the eastern arm of the rille westward. A similar, roughly east-west linear rille appears across the bottom of the image. Both of these linear rilles are older than most of the other rilles which cut them and are sharper edged and deeper. Four are so riles extend north and open outward a little like a stylized Japanese flower arrangement. The youngest of these rilles is the diagonal one that crosses everything else. Like the western arm of the Hyginus Rille it is roughly radial to the center of the Imbrium Basin, implying some causal relationship.
