Binoculars are two mirror-symmetrical and identical telescopes mounted side-by-side and aligned to point accurately in the same direction, permitting two-eye viewing. The need for using sophisticated equipment for viewing the stars has limited the number of participants.
The first thing to know about a compact binocular is that it is two small telescopes mechanically linked together. Most binoculars are lightweight, portable, and very easy to carry. For most uses, look for a objective diameter that is five times the magnification power.
If you are using binoculars with a large, heavy objective lens it is helpful, if not necessary, to stabilize them by either resting them on something or mounting them on a tripod. In live theaters and concerts, audience members sitting in the back rows away from the stage use binoculars to get a better view of the stage.
You will find these to be quality binoculars that won't break should you drop them. The higher end models also tend to use technology that improves stabilization and increases view quality. Galactic clouds and star clusters look dim when viewed by the naked eye, but with binoculars they are much clearer.
You want to keep these for years to come so you might as well be comfortable. You will stare in the windows for hours and discover many thing that otherwise would be missed.
