lunar 100
by andrea vanoni
Il Lunar 100 (L100) è un elenco di cento caratteristiche più interessanti da osservare sulla Luna. L'elenco è stato descritto per la prima volta da Charles A. Wood nell'articolo The Lunar 100 sulla rivista Sky & Telescope, nell'aprile 2004. Con questa selezione, Wood ha cercato di fornire agli appassionati di astronomia un elenco simile al catalogo di Messier degli oggetti del cielo profondo, ma di un oggetto più familiare, la Luna. Gli oggetti elencati includono crateri, mari, montagne e altri elementi e sono disposti in ordine crescente di difficoltà di osservazione.
Tutte le riprese che troverete sono state fatte da Andrea Vanoni con strumentazione differente, nel corso degli anni e in fasi lunari differenti. Alcune zone sono state faticose da riprendere a causa della librazione lunare non sempre favorevole.

The Lunar 100 (L100) is a list of one hundred of the most interesting features to observe on the Moon. The list was first described by Charles A. Wood in the article The Lunar 100 in Sky & Telescope magazine, April 2004.
With this selection, Wood tried to give astronomy fans a list similar to the Messier catalog of deep-sky objects, but of a more familiar object, the Moon. The objects listed include craters, seas, mountains and other features, and are arranged in ascending order of observational difficulty.
All the shots you will find were made by Andrea Vanoni with different instruments, over the years and in different phases of the moon. Some areas were tiring to shots due to the not always favorable lunar libration.
