Gassendi

Now all of Mare Humorum is bathed by the morning sunlight, along with it the magnificent crater Gassendi (114 km) on its northern border. For some reason Gassendi is the Moon’s most frequently observed, sketched and imaged feature. Its floor contains a prominent cluster of central peaks and is crossed with an intricate network of rilles, all easily visible through a 150 mm telescope.

In the southern uplands the crater Schiller (184 km) is an intriguing sight – an elongated feature which gives the impression of being a crater which was squashed from east to west.
