• Check the alignment at nighttime by repeating this
process with a bright star or the moon. Make any
necessary adjustments.
Now that your finder scope is properly aligned, any object
centered in your finder scope should also be centered in
your telescope.
Calculating Power:
The magnification of a telescope depends on both the focal
length of your telescope as well as the eyepiece you use.
There is a simple formula you can use to determine the
magnification you are using at any given time. Simply divide the
focal length of the telescope by the focal length of the eyepiece.
For example, if you are using the 25mm eyepiece with your
SV-350 telescope the power would be:
Power = 400mm / 25mm = 16x
Using an eyepiece with a smaller focal length will increase the
magnification of your telescope. It is always best to start at the
lowest magnification configuration. The wider field of view
makes it easier to spot far away objects. Once an object is
centered in your field of view you can switch to the higher power
configurations. Using the 2x Barlow Lens will multiply the
magnification 2 times.
Understanding Celestial Movement:
In order to get the most enjoyment out of your telescope it is
necessary to know the basics of how celestial objects move
across the sky. Due to the rotation of the earth, celestial objects
appear to move from East to West across the sky, much like
the Sun. You will notice this movement as an object in your
telescope field of view will slowly move across the field and out
of view. Continuous adjustment is needed to keep an object in
the field of view.
