Some of the craters are huge, with diameters of well over 150 miles (240 km), while others are tiny pits. In general their walls do not rise to the great heights above the outer country; the floors are sunken, but seen in profile they resemble saucers rather than steep-sided mine-shafts. Many of them have central mountains, or groups of mountains. Thus Theophilus, on the edge of the Mare Nectaris (Sea of Nectar) is 64 miles (102 km) across, with walls rising to 18,000 feet (6,000 m) above a floor upon which is a magnificent, many-peaked central mountain mass.
Used properly and with proper precautions full-aperture solar filters are completely safe, but you must make sure that the filter comes from a ‘known’ source, is in good condition, and is very securely fixed in place. Never, ever use anything other than a purpose-made full-aperture solar filter for this purpose. Other materials may look similar, but could blind you! At the time of writing, in the US and some other countries you can buy less costly filters made of metal coated mylar, a thin, tough plastic.
