How these drawings are made
Each drawing is computed for this city and the minute under it: where the Earth's shadow falls on the Moon (Astronomy Engine's model: the Earth's radius plus 88 km of atmosphere, the convention that matches NASA's contact times), turned as the Moon stands in this city's sky.
The penumbra is drawn as the faint shading it is: the eye notices it only in its deepest part, next to the umbra. While part of the Moon is still lit, the umbra looks dark grey.
At totality the Moon is drawn a dark red-brown. The real colour changes from one eclipse to the next, from bright copper to almost black (the Danjon scale, L0 to L4), and cannot be predicted: it depends on the dust and clouds in the Earth's atmosphere that night.
Up is the zenith as you face the Moon. An astronomical telescope turns the view upside down, or mirrors it if it has a diagonal.

What you will actually see, and with what
A lunar eclipse is safe to look at with the naked eye, from start to finish: it is the full Moon, dimmed.
10×50 binoculars: what they show, and what they cost
Binoculars show the colour and the edge of the shadow better than the eye. A 10×50 pair magnifies 10 times, with 50 mm lenses and a 5 mm exit pupil: steady enough to hand-hold, bright enough for a darkened Moon.
During totality the Moon turns copper, brick or brown, never the same twice: how dark depends on the dust and clouds in the Earth's atmosphere.
