Although our telescopes are designed with portability in mind, it is important to use proper lifting techniques to prevent back injury and/or strained muscles. Whenever possible, use two people to move or lift the equipment and make use of wheeled devices like carts or dollies for additional aid.
  • Page 8 Each scope in our AR Doublet Series comes with a non-illuminated straight finder scope: This classic reverse-view finder scope has a simple crosshair that can be centered on your target.
  • Page 9 AR DOUBLET SERIES COLLIMATION Although the optics in your telescope were carefully aligned in our quality control department prior to leaving our facility, the shipping process could have caused slight shifts in the positions of the three lenses. In case such a slip should occur, your telescope is equipped with a three-point push/pull collimation cell that can be used to realign your optics for optimal performance.

    ED TRIPLET ESSENTIAL SERIES Welcome to our ED Triplet Essential Series Designed to deliver crystal clear imagery rich in contrast, the premium telescopes in our ED Triplet Essential Series are the ideal optical instruments to capture the universe’s breathtaking sights. Available in three apertures ranging from a grab-and-go 80mm to a versatile 127mm, these apochromatic refractors produce stunning views of countless celestial treasures like the Moon’s chiseled craters, Saturn’s elegant rings or the churning spiral of the face-on Pinwheel Galaxy.
  • Page 11 ED TRIPLET ESSENTIAL SERIES are packaged in plastic bags and the telescope’s tube is wrapped in tissue. To begin assembly, slowly remove the optical tube. All models will come with their cradle rings attached, which makes for easy removal. Rarely, the cradle could have come open during packing or shipping, so it is important to check the latches and then do a quick, small lift by the cradle handle to make sure the ring is secure before pulling the instrument all the way out.
  • Page 12 ED TRIPLET ESSENTIAL SERIES CRADLE RINGS (The following section does not apply to the 80mm model, as it does not include or need a cradle ring. Instead, the 80mm has a vixen dovetail plate attached directly to the OTA.) To attach the 102mm or 127mm model to a mount you will need to use the individual model’s included cradle ring set.

Please note that when the final adjustments are made, the center locking screw must have enough engagement with the threads of the cradle ring to make sure that the saddle plate stays connected.

  • Page 18: Twilight Series Mounts

    TWILIGHT SERIES MOUNTS TWILIGHT I MOUNT TWILIGHT II MOUNT THE TWILIGHT SERIES MOUNTS It takes more than high-end optics to truly connect with the universe. Our versatile and durable Twilight Series mounts are designed to give your telescopes the stable foundations they need to gracefully navigate the sky.
  • Page 19 TWILIGHT SERIES MOUNTS PARTS Please Note: We recommend that you keep the original shipping box and packing materials if possible, in case your mount should ever need to be returned for service or warranty purposes. Before beginning the assembly process, we recommend taking an inventory of all parts.
  • Page 20 TWILIGHT SERIES MOUNTS Installing the Head Mount Remove the head mount from its box and take off the bubble wrap and plastic. Align the notch in the head mount with the post on the tripod housing. From below, turn the T-bar to thread the support assembly up into the head mount.
  • Page 21 TWILIGHT SERIES MOUNTS TWILIGHT II ASSEMBLY AND USE To begin assembly, take the tripod out of its box and remove the plastic wrap. Spread the legs fully apart and make sure the two tension screws on each leg are tight. Once you have finished assembling the mount, you can adjust the tripod height by loosening these tension screws, extending each leg equally and retightening the screws.
  • Page 22 TWILIGHT SERIES MOUNTS with the interior wall of the dovetail holder. Slide the dovetail plate that is connected to your telescope into position and firmly retighten the screws. A second telescope can be mounted on the other side using the same process. Moving the Mount The head mount has two large dials that control the vertical (altitude) and horizontal (azimuth) movement of any mounted telescopes.

  • Page 23: Eyepieces

    Designed to provide wide fields of view for a full immersion experience, Explore Scientific’s premium eyepieces ensure stunning detail with high-end optics that allow your telescope to reach its full potential. We offer five series of eyepieces that differ in factors like field of view, available focal lengths, barrel diameter and eye relief.
  • Page 24 EYEPIECES MAGNIFICATION One of the main roles the eyepiece plays is setting the magnification or power of a specific optical set-up. The amount of magnification you will want to use depends largely on your subject. To calculate magnification, divide the focal length of the telescope by the focal length of the chosen eyepiece.
  • Page 25 When coma is present, stars in the center of the field will pop like precise points of light, but stars at the edge take on an unnatural comet-like shape. Explore Scientific’s Coma Corrector can help you minimize or even eliminate image aberrations caused by this off- axis optical phenomenon even in fast Newtonians.

    Non-Illuminated Straight Finder Scope: This classic reverse-view finder scope has a simple crosshair that can be centered on your target. It features a front focus with locking ring and a bright 6° field of view. Illuminated Straight Finder Scope: Explore Scientific’s original straight-style, correct-image finder scope has a precision-etched illuminated open circle, crosshair reticle with adjustable deep red LED illumination that makes target acquisition easy.
  • Page 27 FINDER SCOPES as many contain fiberglass particles that can be abrasive. FOCUSING YOUR FINDER SCOPE (Please note: This section does not apply to our Non-Illuminated Straight Finder Scope, which does not have a focus feature.) Our illuminated finder scopes allow for focus adjustments of both the objective lens and the eyepiece.
  • Page 28 FINDER SCOPES We recommend doing that first alignment in the daytime using a land-based target. Be careful to do this in an area where you will not accidentally point either your telescope or finder scope at or near the Sun, (see Sun Warning in this manual). After you have set up your telescope and attached the finder scope, find an easy, stationary target that is at least 200 meters away.

  • Page 29: Focusers

    FOCUSERS Introduction To Our Focusers It takes more than excellent optics for your telescope to truly perform. If you want to capture the intricacies of our Moon’s winding Hadley Rille or the spiraling arms of the Pinwheel Galaxy, you will need to have a superior focuser in your astronomical arsenal. The focuser is one of the most important mechanical components of your telescope because it is the tool you use to find and hold that perfect crisp image.
  • Page 30 FOCUSERS Crayford-Style Non-Rotatable Focuser This focuser has a flat plane on the bottom side of the drawtube that rides along a roller assisted by ball bearings to smoothly adjust the focus. On this 2” focuser, the tension and locking screws are both located on the bottom of the focuser, with the smaller of the two serving as the locking mechanism that holds the focus dials stationary.
  • Page 31 FOCUSERS tightening the four smaller screws equally using a 2mm hex wrench. It is important to make sure each of the four screws is tightened the same amount to avoid giving the drawtube an awkward and unbalanced tilt. Also be sure to make these adjustments in very small increments.

  • Page 32: Share The Sky

    SHARE THE SKY Share the Sky! Awakening individuals to the marvels of the universe can be one of the most rewarding aspects of owning a telescope. When you share your eyepiece with others, you can witness their sense of wonder bloom as they take in celestial spectacles like the chiseled lunar terrain, the elegant rings of Saturn or the blue-white stars of the misty Orion Nebula for the first time.
