    These instructions detail the set-up, operation, specifications, and optional accessories of your Jupiter 114 EQ-D. In order that you may achieve maximum enjoyment of the instrument, we urge that you take a few minutes to read all of this manual before making first observations through the telescope.

  • Page 7: Balancing The Telescope

    In order for the telescope to move smoothly on its mechanical axes, it must first be balanced about the 2 telescope axes: the polar axis (10, Fig. 1) and the Declination axis (21, Fig. 1). All motions of the polar aligned telescope (more on this later) take place by moving about these two axes, separately or simultaneously.

    • Unlock the R.A. lock (22, Fig. 1) and the Dec. lock (23, Fig. 1) so that the telescope turns freely on both axes. Then point the main telescope at some well-defined land object (e.g. the top of a telephone pole) at least 200 yards distant, and re-lock the R.A and Dec. axes. Turn the flexible cable controls, (3, Fig.

  • Page 9: Lining Up With The Celestial Pole

    The setting circles, R.A (27, Fig. 1) and Dec. (28, Fig. 1) of the Polaris 114 EQ-D telescope may be dialed, in effect, to read the object coordinates and the object found without resorting to visual location techniques. However, these setting circles may be used to advantage only if the telescope is first properly aligned with the North Celestial Pole.

  • Page 10: Using The Telescope

    The Jupiter 114 EQ-D may be used for a lifetime of rewarding astronomical observing, but basic to your enjoyment of the telescope is a good understanding of the instrument. Read the above instructions carefully until you understand all of the telescope’s parts and functions.

  • Page 11: Using Setting Circles

    For example, the focal length of the Jupiter 114 EQ-D telescope is fixed at 900mm. To calculate the power in use with a particular eyepiece, divide the focal length of the eyepiece into the focal length of the main telescope.

  • Page 12: Maintenance

    Assorted eyepieces are available both to increase and decrease the operating eyepiece power of the telescope. If the Jupiter 114 EQ-D is used on a regular basis, a selection of four to five eyepieces is recommended. For example, an eyepiece assortment of focal lengths 40mm, 25mm (Included as standard equipment), 12.5mm, 9mm, and 6mm yields a magnifying range of 22.5x, 36x, 72x, 101x, and...

    (2, Fig. 6), to allow free turning movement of the tilt knobs. • Using the flexible cable controls (3 and 4, Fig. 1), move the telescope until the star image is at the edge of the field-of-view in the eyepiece, as in Fig. 10B.
  • Page 14 Choose one of the 3 primary mirror tilt screws and slightly move the shadow to the center of the disk. Then slightly move the telescope using the flexible cable controls to center the star disk image in the center of the eyepiece.

  • Page 15: Optional Accessories

    For Photography To allow use of the Jupiter 114 EQ-D for photography, the following accessories must be purchased: Variable Projection Camera Adapter (1.25" O.D.): The Variable Projection Camera Adapter includes a machined sliding mechanism, permitting variable projection distances during eyepiece-projection photography.
