  • Page 6: Assembly

    This section covers the assembly instructions for your AstroMaster telescope. Your telescope should be set up indoor the first time so that it is easy to identify the various parts and familiarize yourself with the correct assembly procedure before attempting it outdoor.

  • Page 7: Moving The Telescope Manually

    6 Hand tighten the mounting platform safety screw until the tip touches the side of the mounting bra NOTE: Never loosen any of the knobs on the telescope tube or mount other than the R.A. and DEC k Figure 2-11 .

  • Page 8: Installing The Diagonal & Eyepieces ( Refractor)

    2 above. he eyepiece (or ocular) is an optical element that magnifies the image focused by the telescope. Without the eyepiece it would be impossible to use the telescope visually. Eyepieces are commonly referred to by focal length and barrel diameter The longer focal length (i.e., the larger the number) the lower the eyepiece...

  • Page 9: Telescope Basics

    A Newtonian reflector uses a single concave mirror as its primary. Light enters the tube traveling to the mirror at the back end. There light is bent forward in the tube to a single point, its focal point. Since putting your head in front of the telescope to look at the image with an eyepiece would keep the reflector from working, a flat mirror called a diagonal intercepts the light and points it out the side of the tube at right angles to the tube.

  • Page 10: Image Orientation

    If you have astigmatism, corrective lenses must be worn at all times. The Star Pointer is the quickest and easiest way to point your telescope exactly at a desired object in the sky. It's like having a laser pointer that you can shine directly onto the night sky.

  • Page 11: Calculating Magnification

    4.Without moving the main telescope, turn the Star Pointer's two adjustment screws until the red dot is directly over the alignment star. Experiment as to which way each screw moves the red dot.

  • Page 12: Determining Field Of View

    This inconsistency can and will affect the ability to focus your telescope. In most cases you will not be able to achieve a truly sharp image, while in some cases, you may actually see a double image.

  • Page 13: Astronomy Basics

    Up to this point, this manual covered the assembly and basic operation of your telescope. However, to understand your telescope more thoroughly, you need to know a little about the night sky. This section deals with observational astronomy in general and includes information on the night sky and polar alignment.

  • Page 14: Motion Of The Stars

    The daily motion of the Sun across the sky is familiar to even the most casual observer. This daily trek is not the Sun moving as early astronomers thought, but the result of the Earth's rotation. The Earth's rotation also causes the stars to do the same, scribing out a large circle as the Earth completes one rotation.

  • Page 15: Celestial Observing

    With your telescope set up, you are ready to use it for observing. This section covers visual observing hints for both solar system and deep sky objects as well as general observing conditions which will affect your ability to observe.

  • Page 16: Observing Deep Sky Objects

    One convenient way to find deep-sky objects is by star hopping. Star hopping is done by using bright stars to "guide" you to an object. For successful star hopping, it is helpful to know the field of view of you telescope. If you’re using the standard 20mm eyepiece with the AstroMaster telescope, your field of view is approximately 1º.
  • Page 17 5. Move about ½° toward Beta (β) Lyra, while remaining on a line connecting the two stars. 6. Look through the telescope and the Ring Nebula should be in your field of view. The Ring Nebula’s angular size is quite small and difficult to see.

  • Page 18: Seeing Conditions

    Viewing conditions affect what you can see through your telescope during an observing session. Conditions include transparency, sky illumination, and seeing. Understanding viewing conditions and the effect they have on observing will help you get the most out of your telescope.

  • Page 19: Astrophotography

    During the last few years a new technology has evolved which makes taking superb images of the planets and moon relatively easy and the results are truly amazing. Celestron offers the NexImage (# 93712) which is a special camera and included is software for image processing.

  • Page 20: Telescope Maintenance

    This will prevent contaminants from entering the optical tube. Internal adjustments and cleaning should be done only by the Celestron repair department. If your telescope is in need of internal cleaning, please call the factory for a return authorization number and price quote.
  • Page 21 The telescope should be set up at night and a star's image should be studied at medium to high power (30-60 power per inch of aperture). If a non-symmetrical focus pattern is present, then it may be possible to correct this by re-collimating only the primary mirror.
  • Page 22 IMPORTANT: After making the first, or each adjustment, it is necessary to re-aim the telescope tube to re-center the star again in the center of the field of view. The star image telescope tube to re-center the star again in the center of the field of view. The star image...
