Description

Countless craters fighting for attention

Tycho, ( 85km ) the brightest impact crater, ( lower right ) is the most extensive system of bright rays on the near side of the Moon. The rays, which are light-coloured streaks formed of material ejected from the impact, dominate the southern highlands and extend for more than 2,600 km (1,600 miles) across the Moon’s surface. In this image they can be seen stretching over Clavius and Longomontanus craters. Tycho is one of the deepest Moon craters at 4.8km deep.
Another crater that dominates this western side of the southern highlands is of course Clavius with its arc of small craters and numerous craterlets, some only half a km in diameter are a good target for us astrophotographers and provide us with a good guide to the resolving power of our telescopes.
