Where to point your Christmas telescope

If you found a new telescope under the Christmas tree, congratulations. You're about to get close and personal with your universe.
Be patient. Too many Christmas telescopes wind up as an extra coat rack because of overblown expectations followed by disappointment. Take your time with the new scope and thoroughly read the instructions.

Don't be fooled by Christmas telescopes

The Christmas advertising season seems to hit a little earlier every year. Buried in those gigantic advertising supplements, you will find alluring photos of small telescopes that aren't particularly adequate for stargazing. These days, a more insidious trap awaits the unwary telescope buyer. Those small 'scopes now sometimes have computers attached to them. The computer will find the moon for you. At last, it seems, we are free of the burden of knowing the complexities of the nighttime sky....

To those advertising cheap astronomical telescopes, the word "power" is usually applied to the magnification of the telescope.
In truth, magnification is of limited use. The true power of an astronomical telescope is its ability to collect light. Most astronomical objects are faint, and things a long way away can be very faint. To see distant galaxies formed close to the beginning of the universe, we are faced with the problem of observing very faint objects indeed.

You can change the magnification of any telescope simply by switching out the eyepiece. To determine the magnification, divide the focal length of the telescope by the focal length of the eyepiece. These measurements will be displayed on the box and in the booklet that comes in it. The focal length of the eyepiece will be clearly displayed right on the eyepiece.
For example, a telescope with a focal length of 1500mm paired with a 25mm eyepiece will give the telescope a 60x magnification (1500/25 = 60). If you swap the 25mm eyepiece with a 10mm eyepiece, the same telescope's magnification increases to 150x (1500/10 = 150).
