The image seen through monoculars appear in their correct orientation through the use of two prisms, whereas in most telescopes the images are inverted. Think about it, binoculars are inexpensive, highly portable and require no complicated setting up procedure.
Compact binoculars are mostly used by travelers, sportsmen, hunters, bird watchers, and nature lovers. Many pairs of binocualrs are not suitable for low-light conditions. That s the reason why astronomers prefer monoculars.
The third- and fourth-generation night-vision binoculars show much clearer images at night, and are priced higher that the previous generation binoculars. Objects will appear brighter with wider lenses.
Costlier monoculars with 30x or greater magnifications are made of better prisms and lenses. You can easily calculate it by dividing the aperture by the magnification so that 7 x 50 binocular has an exit pupil of just over 7mm. Low light uses such as hunting, birding and astronomy require larger objective lenses.
There is much more to astronomy then buying a telescope. Get Outdoors!
