Binoculars for Astronomy
Some binoculars are designed in a specific order to use in astronomy as a device to see the stars. Another name of these binoculars is Giant binoculars because of their huge size. Objective lenses and magnifications of these binoculars collects much light than other binoculars.
Sometimes they are designed without prisms to allow much light transmission. They have changeable eyepieces, heavy weight and high magnification power to see the image from distance places. Amateur telescope makers made larger binoculars using two reflecting telescopes. These binoculars are used for viewing the deep sky objects as milky way and galaxies. The magnification is an important factor to observe star clusters, galaxies and nebulae.
Marine binoculars are designed with some special quality because they should be fully waterproof, can float, and with a compass. There are prisms in such binoculars that have aluminized coating so that they won’t lose reflective qualities even if they get drenched.

Size of Binoculars
Binoculars could break down into full-size, midsize and compact categories that depends on the measurement of the objective lenses. Same size of the model lenses may be different in weight and size.
