  • Page 6: Using Your Telescope

    Faint deep sky objects become difficult or impossible to see through the murk of light pol- lution. Even bright nebulas like the Orion and Lagoon Nebulas lose much of their delicate detail. The Moon and planets are not affected; they require steady air more than dark skies, so they remain good targets for city- dwelling observers.

  • Page 8 What to Expect So what will you see with your telescope? You should be able to see bands on Jupiter, the rings of Saturn, craters on the Moon, the waxing and waning of Venus, and many bright deep-sky objects.

  • Page 9: Care And Maintenance

    The Milky Way is best observed on summer and winter evenings. Care and Maintenance If you give your telescope reasonable care, it will last a life- time. Store it in a clean, dry, dust-free place, safe from rapid temperature changes and humidity. Do not store the telescope outdoors, although storage in a garage or shed is OK.
  • Page 10 The secondary mirror itself should be cen- tered in the focuser drawtube, in the direction parallel to the length of the telescope. If it isn’t, as in Figure 10b, it must be adjusted. This adjustment will rarely, if ever need to be done.

  • Page 11: Appendix B: Cleaning The Optics

    Star-Testing the Telescope When it is dark, point the telescope at a bright star and accurate- ly center it in the eyepiece’s field of view. Slowly de-focus the image with the focusing knob. If the telescope is correctly colli- mated, the expanding disk should be a perfect circle (Figure 15).
