1. | The image I see in the telescope is upside down and | ∙ | An | is a common | |
| reversed from right to left ? |
| characteristic of most astronomical telescopes. Since | ||
|

|
| finderscope will also be reversed. |

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: | ||
|
|
| 1000 ÷ 25 = 40X) |
|
|
|
|

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 | |
|
|
| 540mm. Telescope focal lengths range from 540mm | ||
|
|

4. | What can I see with my telescope ? | ∙ Telescopes with power ranging from 25X to 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. |

1.I’ve completed the
∙Check to see if objective lens cover has been removed.
∙Try to view an object that is 200 or more yards away.
∙If there is more than one eyepiece included with the telescope, use the lowest power (highest number) eyepiece to begin viewing.
∙Use the Rack & Pinion Focusing Mechanism (3) to bring the object you are trying to view into focus
