ANSWERS TO COMMONLY ASKED QUESTIONS
1. | The image I see in the telescope is upside down and | ∙ An |
reversed from right to left ? | common characteristic of most astronomical | |
|
| telescopes. Since telescopes are used for |
|
| astronomical viewing orientation is not important. |
|
| The image in the finderscope will also be upside |
|
| down and 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 1000mm. Telescope focal lengths |
|
| range from 600mm to 1000mm on Bausch & Lomb |
|
| and Bushnell telescopes. |
|
|
|
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. |
|
|
|
5. | What do the numbers on the eyepiece mean ? | ∙ The numbers on the eyepiece represents the |
|
| “focal Length” of the eyepiece. |
