Astronomy telescope is a great way to open up the wonders of the Universe to the aspiring astronomer! With incredible resolution, this refraction telescope shows amazing details for both astronomical and land observations! This astronomical telescope with 80 to 233X finderscope and tripod is perfect for stargazing! With 70mm objective lens, this optical telescope can produce bright, clear images of the moon and planets. Taken your first step into the stars of the world, your life will have more fun. Astronomical telescope has perfect design and skillful manufacture. This astronomical telescope is a modified monocular telescope used to magnify the images of distant objects by passing light through a series of lenses and sometimes prisms. Volume and weight are less than half those of binoculars of similar optical properties, making it easy to carry. When high magnification, a bright image, and good resolution of distant images are required, a relatively large instrument is preferred, often mounted on a tripod. This Refracting Astronomical Telescope is an ideal entry level telescope! Make the stars come to you! This astronomical telescope with tripod is perfect for stargazing.

    How to Use a Refracting Telescope:

    Jeahar 80-233 x 70mm Refracting Astronomical Telescope

    Refracting telescopes employ glass lenses arranged in a metal tube to gather light from distant objects, such as the moon, planets, star clusters and nebulae. When used in combination with interchangeable magnifying eyepieces, a refracting telescope lets you study these astronomical objects in extraordinary detail. Refractors offer improved optical clarity when compared with reflector telescopes, which use mirrors instead of glass lens. Learn to operate your refracting telescope correctly to take advantage of its superior optical capabilities

    Instructions:

    • Pick an observing site far from light sources. Porch lights, street lights and other sources of light pollution brighten the night sky, making faint objects difficult to observe
    • Lay the tripod on the ground. Extend each tripod leg to the same length, and then tighten the thumbscrews on each leg to secure it in place. Stand the tripod upright. Loosen the thumbscrews on the tripod's mounting bracket. Insert the telescope into the tripod's mounting bracket, and then tighten the retaining screws
    • Loosen the thumbscrew on the telescope's finder scope mount. Insert the finder scope into the mount, and tighten the retaining screw
    • Aim the telescope at an astronomical target. Pick a bright object, such as the moon or a star. Raise or lower the tube, and move it from side to side to point the telescope in the target's general direction
    • Look through the finder scope. Adjust the orientation of the telescope to center the object in the finder scope
    • Insert a low-power eyepiece -- one with 75X or lower magnification -- into the telescope's focuser. Tighten the retaining screw to secure it in place. Look through the eyepiece and verify that the object is in the field of view. If not, look through the finder scope and re-center the object. Adjust the focuser knob until the object appears sharp in the eyepiece
    • Insert a high-power eyepiece -- one with greater than 75X magnification -- into the telescope's focuser to study the object in greater detail. Adjust the focuser to sharpen the object in the eyepiece

    Tips & Warnings:

    • Consult the telescope's user manual to determine its focal length. Knowing the focal length lets you determine what magnification an eyepiece will provide when used with the telescope. Divide the focal length of the telescope by the focal length of the eyepiece to calculate the resulting magnification. A 600mm telescope, for example, provides 60X magnification when used with a 10mm eyepiece
    • Observing the sun through a telescope will seriously damage your vision

    How Are Telescopes Made?

    Jeahar 80-233 x 70mm Refracting Astronomical Telescope

    Optical Telescopes:

    • Optical telescopes use a series of lenses or a curved mirror to focus visible light. Optical telescopes that only use lenses are called refracting telescopes. Optical telescopes that use a mirror are known as reflecting telescopes. They are usually more powerful than a simple lens telescope

    Lenses and Mirrors:

    • Since light passes through the lenses of a telescope, the glass has to be free of impurities. This quality of glass is known as optical glass. Optical glass is coated to improve its performance and to make it less reflective. Mirrors that refract the glass don't have to be as pure

    Assembly, Calibration and Testing:

    • Once the glass and mirrors are created, the lenses are also tested to ensure that the glass has been ground correctly. To do this, telescope makers measure the lens against a lens that is known to be perfect. Once the lenses pass inspection, they are assembled in a tube-like telescope housing. Then they are calibrated for clarity

    Package Included:

    • 1 x Telescope
