Victor Hugo a écrit dans Les Châtiments : "Les horizons aux horizons succèdent […] : on avance toujours, on n’arrive jamais ". Face à la mer, vous voyez l'horizon à perte de vue. Mais "est-ce loin, l'horizon ?". D'après toi, jusqu'à quelle distance peux-tu voir si le temps est clair ? Réponse 1 : " Sans instrument, je peux voir jusqu'à .................. km " Réponse 2 : " Avec une paire de jumelles, je peux voir jusqu'à ............... km " 2. Nous allons maintenant calculer à l'aide du théorème de Pythagore la ligne d'horizon pour une hauteur H donnée.

Z założenia podręcznik ma być wyczerpującym przewodnikiem obserwacji gwiazd zmiennych. Zawiera on dużo podstawowych informacji z wydanego w 1970r. przez Margaret W. Mayall, byłej dyrektor AAVSO, Podręcznika Obserwacji Gwiazd Zmiennych, jak również informacje z różnych materiałów obserwacyjnych AAVSO opublikowanych od tego czasu. Podręcznik ten dostarcza najnowszych informacji na temat wykonywania obserwacji gwiazd zmiennych i składania sprawozdań z obserwacji do AAVSO. Dla nowych obserwatorów podręcznik ten jest podstawowym narzędziem – jedną z publikacji, z których może on uzyskać wszystkie potrzebne informacje do rozpoczęcia programu obserwacyjnego gwiazd zmiennych. Z drugiej strony, długoletni i doświadczeni obserwatorzy oraz ci, powracający do obserwacji gwiazd zmiennych, mogą go uznać przydatnym jako podręczne, szybkie źródło informacji lub tekst odświeżający, pomocny w odkrywaniu nowych aspektów obserwacji gwiazd zmiennych. Podręcznik ten zapozna Cię ze znormalizowanymi procesami i procedurami obserwacji gwiazd zmiennych – bardzo ważną częścią wykonywania i dostarczania Twoich obserwacji do AAVSO. Znajdziesz tutaj nowe informacje, przedstawione w przydatnej formie, z rozdziałami ułożonymi według wzrastającej trudności i zgrupowanymi według treści przedmiotu. Dla tych, którzy wolą mieć istotne informacje w swoim notesie lub foliowych koszulkach, jest wiele stron do skopiowania.

    TAAS Monthly Observing Challenge December 2015 Deep Sky Object NGC 772 (GX) Aries ra: 01h 59m 20.1s dec: +19° 00’ 26” Magnitude (visual) = 10.3 Size = 7.2’ x 4.3’ Position angle = 130° Description: NGC 772 (also known as Arp 78) is an unbarred spiral galaxy approximately 130 million light-years away in the constellation Aries. Around 200,000 light years in diameter, NGC 772 is twice the size of the Milky Way Galaxy, and is surrounded by several satellite galaxies – including the dwarf elliptical, NGC 770 – whose tidal forces on the larger galaxy have likely caused the emergence of a single elongated outer spiral arm that is much more developed than the others arms. Halton Arp includes NGC 772 in his Atlas of Peculiar Galaxies as Arp 78, where it is described as a "Spiral galaxy with a small high-surface brightness companion". Two supernovae (SN 2003 hl & SN 2003 iq) have been observed in NGC 772.

Visually, it appears like it could be two separate objects; therefore, two entries were given to the planetary nebula by William Herschel in the "New General Catalogue", so it may be referred to as NGC 2371, NGC 2372, or variations on this name.
