    We have provided basic instructions for telescope use and astronomical viewing in this manual. Your Zhumell Eclipse 114 Reflector Telescope is built with the highest-quality optics and top-notch construction to provide years of reliable functionality, but will require proper care.

  • Page 5: Cleaning And Maintenance

    Do not remove optical elements from the telescope as doing so may affect the alignment of optical components when reassembled. If telescope needs realignment, contact Zhumell or another professional. Brush telescope optics with camelhair brush or blow off dust with an ear syringe (can be purchased at any pharmacy).
  • Page 6 Periodically, you will find that it is necessary to align the optical components of your telescope. This procedure is called collimation. There is no collimator included with the Eclipse 114, but regular collimation is recommended for optimum telescope usage. Remove the eyepiece from the eyepiece holder and insert laser collimator into eyepiece holder.

    ASSEMBLY OF YOUR ZHUMELL ECLIPSE TELESCOPE TRIPOD ASSEMBLY STEP 1: Spread out the Tripod legs so that it can stand on its own. Attach the Accessory Tray to the three connection points on the Tripod legs. Tighten using the thumbscrews on the attachment points.
  • Page 11 ASSEMBLY OF YOUR ZHUMELL ECLIPSE TELESCOPE CONNECTING MOTOR DRIVE TO EQUATORIAL MOUNT STEP 1: Remove the silver bolt head and washer located in the middle of the mount. Slide the L-shaped bracket on the Motor Drive over the exposed bolt and screw the washer and bolt head securely over.
  • Page 12 ASSEMBLY OF YOUR ZHUMELL ECLIPSE TELESCOPE STEP 2: Loosen the thumbscrew on the shorter cable. This is the Declination Adjustment cable. Slide it over the exposed bolt directly opposite the Motor Drive assembly and tighten with the attached thumbscrew. When in place, it should be facing outward, parallel to the ground.
  • Page 13 ASSEMBLY OF YOUR ZHUMELL ECLIPSE TELESCOPE CONNECTING THE OTA RINGS TO THE ATTACHMENT PLATE STEP 1: One at a time, remove the butterfly screws on each OTA Ring and slide into the hole on the attachment plate. Tighten the butterfly screw on the other side of the plate until the ring is secure. Make sure both rings are in place and tightened before moving on.

  • Page 14: Attaching The Finderscope

    ASSEMBLY OF YOUR ZHUMELL ECLIPSE TELESCOPE STEP 2: While supporting the OTA with your hand, close and tighten the OTA Rings over the entire assembly. Double-check that these connections are secure before moving on - damage to the OTA is likely to be irreparable.

Screw the Eyepiece Extender onto the threads until secure. ATTACHING THE EYEPIECE EXTENDER STEP 1: You will need to attach an eyepiece to use your telescope. Choose one of the included eyepieces and slide it into the Eyepiece Extender, silver side first.

  • Page 16: Checking And Aligning Your Finderscope

    The lack of color is due to human anatomy, not any limitations of telescope construction. CHECKING AND ALIGNING YOUR FINDERSCOPE Finderscope alignment is the first step to fine-tuning your Eclipse 114 setup and viewing celestial objects. Follow these steps to properly set up and align your finderscope.
  • Page 17 ZHUMELL ECLIPSE TELESCOPE USING THE MOTOR DRIVE The motor drive included with your Eclipse 114 telescope is designed to track the movement of stars so you don’t have to. As long as your telescope is properly polar aligned and the motor drive is properly used, it will help keep stars in your field of view during long periods of viewing.

  • Page 18: Beginning Observation - The Moon

    BEGINNING OBSERVATION - THE MOON As you set out to begin viewing, one of the easiest and most enjoyable objects to look at is the moon. Finding the moon and adjusting to view it is a good way to acquaint yourself with the movements of your telescope. Follow these steps carefully to gain a basic understanding of the adjustments you can make to your scope.
  • Page 19 INTERMEDIATE OBSERVATION - PLANETS Once you’ve used your telescope to view the moon, you should be familiar with the basic movements and adjustments you need. Next stop: the planets. Not all the planets are visible from one area at one time, so you’ll need to do a little research before you begin.
  • Page 20 ADVANCED OBSERVATION GETTING STARTED - ADJUSTMENTS Star charts and the setting circles are the key to taking your celestial observation to the next step. They will allow you to find any known celestial objects your telescope can see. By using the measurements listed on the mount and the coordinates provided in a star chart, you will be able to find stars, planets, nebulae, and galaxies.

  • Page 21: Polar Alignment

    ADVANCED OBSERVATION Use these large-scale movements to point your telescope in the general direction of the object you are viewing. Use the following fine-tuned adjustments to perfectly center it in your view for accurate tracking. • The larger silver circle on your mount is the Hour Circle, which shows the exact Right Ascension of your telescope position.
  • Page 22 ADVANCED OBSERVATION Knowing the location of Polaris (the North Star) and the constellations Ursa Major (the Big Dipper) and Cassiopeia (the Queen) will allow you to properly align your telescope. For Southern Hemisphere viewing, you will need to use a star chart to find stars near the meridian and the celestial equator in order to use the star-drift method for polar alignment.
  • Page 23 ADVANCED OBSERVATION Loosen the Latitudinal Adjustment Screws and raise your telescope until it is pointed at Polaris. Use the focused eyepiece and make fine-tuned adjustments using the Declination Adjustment Cable until Polaris is in the center of the viewfinder. Once your telescope is aligned to Polaris, the number on the latitude scale should match the latitude of your viewing location exactly.

  • Page 24: Rough Alignment

    ADVANCED OBSERVATION ROUGH ALIGNMENT Begin by roughly aligning your telescope to the pole by using the mount’s latitudinal scale. Set the declination scale to 0° to align the OTA with the mount’s polar axis. Check the latitude of your viewing location and set the latitude scale to the same number.
  • Page 25 ADVANCED OBSERVATION Engage the motor drive by tightening the thumbscrew that connects it to the R.A. axis of the mount. Turn on the motor drive, ensuring that it is set to the correct hemisphere setting. Let the motor drive run for about 5 minutes.

  • Page 26: Finding Celestial Objects

    ADVANCED OBSERVATION Repeat Steps 2 - 6 until you are satisfied with the alignment of your telescope. Each time you make adjustments and find a new star, you should notice the drift getting smaller and smaller. The more closely you polar-align your telescope, the more accurately it will track stars.

  • Page 27: Using Setting Circles

    ADVANCED OBSERVATION Center the star in the eyepiece using fine-tune adjustments with the R.A. and Declination Adjustment Cables. Once it sits in the exact center of your viewfinder, turn the hour circle until the arrow points at the appropriate measurement for the star you’re viewing (11h23m for Dubhe, 12h33m for Acrux).
  • Page 28 ASTRONOMY FORMULAS FOR YOUR ZHUMELL ECLIPSE TELESCOPE MAGNIFICATION To determine the magnification of a telescope and eyepiece combinantion, divide the telescope focal length be the eye- piece focal length. Magnification (x) = Telescope Focal Length (mm)/Eyepiece Focal Length (mm) Ex: 20mm Eyepiece with a 114x1000mm telescope.
  • Page 29 ASTRONOMY FORMULAS FOR YOUR ZHUMELL ECLIPSE TELESCOPE LIMITING MAGNITUDE To determine the limiting magnitude of a telescope, use the aperture in the following formula for an approximation. Limiting Magnitude = 7.5 + 5LOG(Aperture in cm) Ex: Limiting Magnitude of a 114x1000mm telescope.
  • Page 30 ASTRONOMY TERMINOLOGY DECLINATION (DEC.) - The astronomical ZENITH - The zenith is the point in the celestial equivalent of latitude. Declination describes sphere directly above your head. The zenith varies the angle of a celestial object above or below depending upon your location. In general, the the celestial equator.
  • Page 31 TELESCOPE TERMINOLOGY OBJECTIVE - The objective is the front lens of a LIMITING MAGNITUDE - The limiting magnitude telescope. The listed measurement for objective of a telescope describes the faintest object you lenses is the lens diameter. A larger objective can see with a telescope.
