ANSWERS TO COMMONLY ASKED QUESTIONS

common characteristic of most astronomical
telescopes. Since telescopes are used for
astronomical viewing orientation is not important.
2. How do I determine the power my telescope ?
• The power of your telescope can be determine
by dividing the focal length of the objective lens by
the focal length of the eyepiece. The eyepiece focal
length is the number printed on the eyepiece. (For
example: 500
÷
5 = 100X)
3. Where do I find the Telescope Focal Length
• The telescope focal length is the same focal
length as the objective focal length. For this
telescope it is 500mm. Telescope focal lengths
range from 500mm to 1200mm on Bausch & Lomb
and Bushnell telescopes.
4. What can I see with my telescope ?

50X can be used to view Star Clusters and Nebulae.
90X to 120X telescope can view galaxies. Most
planets can be seen at any magnification.
