I was out testing my old 10" reflector last night and managed to grab this image though a very slight thinning in the continous cloud layer that seems to be covering the south of the UK at the moment...http://homepage.ntlworld.com/p.lawrence1/newpics/vieta.jpg (shown at left) Not too sure if this is a valid crater ray or not. What alerted me to the fact that it might be is the similarity between this image and another bone-fide crater ray I managed to image back in October of 2003... http://homepage.ntlworld.com/p.lawrence1/craterrays.html Regards, Pete Lawrence

Vieta: -732,-488; A fine crater 50 miles in diameter with loft, terraced walls rising 15,000 feet on the west and 10,000 feet on the east, but low on the south. A ring intrudes on the north, Vieta having overlaid this older crater. On the floor is a small central hill, with two craterlets on its north; three craterlets near the north wall; some low hills near the west wall; and a craterlet south of the center, from which a ridge runs to a ruined ring abutting on the south wall. There is also a low ring under the south-east rim. A distinct cleft runs to the ruined ring on the south-east, and Wilkins has found a cleft crossing the northern portion of the interior. On the southeast are overlapping rings; elsewhere the surroundings contain craters and ridges. To the east are the right crater D, and ruined rings, R S and T.
