Seeing Triangulum
Eyes
Its stars are fairly faint (the brightest, its alpha star, is mag 3.0). You’ll need a sky away from bright lights to trace the pattern.
Binoculars
Binoculars show many more stars than your eye, and bring out star clusters and brighter nebulae inside it.
Telescope
The constellation is far too large for a telescope’s view. Use one for the clusters, nebulae and galaxies inside it.
