Simple Star Gazing with Binoculars
|
|
|
You should know a few things;in regards to
choosing binoculars for observing the stars during your camping trip. Every
pair has a two number designation for magnification and aperture( the diameter
of the front lense in millimeters). The higher the magnification the less your
field of view will be. So, 10 for magnification is sufficient and will not
limit your field of vision; an important thing to consider when trying to pick
out constellations and viewing the tail of a comet. A higher magnification will
also amplify the effect of shaky hands. A telescope with a tripod would
take care of this problem but for our purposes a pair of binoculars is often
more convenient for camping and backpacking trips. You can get image stabilized
binoculars for a higher price. The higher the aperture the more light you
collect which is important for star gazing ( not as important for bird watching
during the day) So, the larger the front lense the better for gazing. When all
is said and done, 8 x 50 is a nice choice for astronomy and Binoculars.
