Every object this site holds, in the order the universe holds them: our own star system first, then our galaxy, then everything past it. Each one has a page saying what it is, whether you can see it, and where to look.
113 objects. 27 of them you can see with nothing but your own eyes; another 33 are within reach of a small telescope (the “150 mm” below is the width of its mirror). The rest nobody can see from a garden; they are here because the universe makes less sense without them.
Six meteor showers come round every year on the same dates. They need no equipment — a telescope only gets in the way.
Everything held by our own star — the planets, their moons, the rubble left over from building them, and the handful of machines we sent out after them.
Our own galaxy: the nearest stars, the clouds where new ones are being made, the wreckage of the ones that died, and the black hole at the middle of it all.
Other galaxies. Andromeda is the furthest thing most eyes can reach without help, and a small telescope reaches several more.
