Everything you can actually see

With nothing but your eyes

Some of these need a properly dark sky and eyes that have had twenty minutes to adjust — which is the single most-skipped step in astronomy. The Sun is here only by projection or through a proper solar filter: never look at it directly.

With binoculars

Binoculars held steady against a fence reach all of these — and so does any telescope. This is where the surprises live: Saturn as an oval, Jupiter’s moons rearranging themselves overnight, and the Orion Nebula resolving from a smudge into a shape.

With a 150 mm telescope, on a good night, if you are patient

A 150 mm telescope is one whose mirror is 150 mm (six inches) across. These are hard: dark sky, no Moon, and knowing exactly where to point.

What is best when

The Earth goes round the Sun, so the night side faces a different direction in each season. That is the whole reason some things are “winter objects” (the seasons here are the northern ones; south of the equator, swap winter for summer):

WinterThe Beehive Cluster (Praesepe), the Crab Nebula, the Orion Nebula, the Pleiades (Seven Sisters), Sirius
Spring3C 273, the Antennae Galaxies (NGC 4038/4039), Arcturus, Bode’s Galaxy (M81), the Cigar Galaxy (M82), M87 / Virgo A, the Pinwheel Galaxy (M101), the Sombrero Galaxy (M104), the Whirlpool Galaxy (M51)
SummerThe Dumbbell Nebula, the Eagle Nebula, the Hercules Cluster (M13), the Lagoon Nebula, RR Lyrae, the Ring Nebula, Sco X-1, Vega, the galactic bar and bulge
Autumn51 Pegasi, Algol, the Andromeda Galaxy (M31), the Fireworks Galaxy (NGC 6946), the Helix Nebula, Mira, SS Cygni, the Triangulum Galaxy (M33)

What you will not see

Colour, mostly. And the arms of galaxies, and the shapes in the famous photographs. Those pictures are hours of exposure through telescopes the size of a house, and colour that your eye cannot collect at low light. The eyepiece views on this site are drawn as things really look through a small telescope, on purpose, so that what you find outside is a surprise rather than a disappointment.
