Portability Telescopes come in various shapes, sizes and different weights.

Black dots or circles of various sizes represent different magnitudes. The majority of star maps normally go down to magnitude +6, but the more specialised stars maps, such as Uranometria display stars that are much fainter. Absolute Magnitude.
