Bushnell 788840 Telescope Specification

The Bushnell 788840 Telescope is designed for both amateur astronomers and seasoned stargazers, offering a blend of precision and ease of use. This telescope features a Maksutov-Cassegrain optical design, known for its compact form and high-quality image production. With a 60mm aperture, it allows for clear and bright views of celestial objects. The telescope's focal length is 700mm, providing a considerable magnification potential that enhances detailed observations of the lunar surface, planets, and deep-sky objects.

Equipped with fully coated optics, the Bushnell 788840 ensures maximum light transmission, which results in high-contrast images with minimal aberrations. Its Red Dot Finderscope aids in easily locating and tracking celestial bodies, simplifying the alignment process for users. The telescope is mounted on a sturdy Altazimuth mount, which facilitates smooth and precise movements in both horizontal and vertical planes, making it intuitive for users of all skill levels to maneuver.

Included with the telescope are two eyepieces, 25mm and 10mm, which provide different magnification levels, allowing for versatile viewing experiences. The lightweight and portable design of the Bushnell 788840 makes it suitable for both backyard stargazing and transport to remote observing sites. The telescope also includes a smartphone adapter, enabling users to capture images of their observations directly onto their phones, perfect for sharing and enhancing the stargazing experience. Overall, the Bushnell 788840 Telescope combines quality optics with user-friendly features, making it an excellent choice for those looking to explore the night sky.

Bushnell 788840 Telescope F.A.Q.

How do I align the Bushnell 788840 telescope's finderscope?

To align the finderscope, first set up your telescope on a stable surface. Choose a distant object during daylight, such as the top of a telephone pole. Center the object in the telescope's main optics. Then, adjust the finderscope's alignment screws until the same object is centered in the crosshairs of the finderscope.

What should I do if the telescope image is blurry?

Ensure that the telescope is focused correctly by adjusting the focusing knobs. Check for any dew or condensation on the lenses and gently clean them if necessary. Also, verify that the eyepiece is securely attached and the correct eyepiece is being used for the desired magnification.

How can I maintain the optical components of the Bushnell 788840?

Regularly check and clean the lenses and mirrors with a soft, lint-free cloth and an appropriate lens cleaning solution. Avoid touching optical surfaces with your fingers. Store the telescope in a dry, dust-free environment when not in use to prevent damage to the optical components.

What is the procedure for collimating the Bushnell 788840 telescope?

Collimation involves aligning the telescope's mirrors. Begin by setting up the telescope in a stable position. Use a collimation cap or laser collimator for precision. Adjust the primary and secondary mirrors using their respective screws until the optical path is properly aligned.

How do I properly transport the Bushnell 788840 telescope?

Disassemble the telescope into its main components: the optical tube, the mount, and any accessories. Use padded bags or cases to protect each part. Secure all components to prevent movement during transport and avoid exposing them to extreme temperatures or moisture.

Why can't I see anything through my telescope at night?

Ensure the lens cap is removed. Check that the telescope is properly focused and that you are using an appropriate eyepiece for night viewing. Allow time for your eyes to adapt to the darkness and make sure you are aiming at a bright celestial object.

What are some common issues with the Bushnell 788840 mount, and how can they be resolved?

Common issues include loose connections and difficulty in smooth tracking. Tighten all screws and bolts to ensure stability. Lubricate moving parts with a non-sticky lubricant if the movement is not smooth.

How can I improve my stargazing experience with the Bushnell 788840?

Choose a location with minimal light pollution. Use a star chart or app to plan your viewing session. Allow your eyes to adjust to the dark for 15-30 minutes. Experiment with different eyepieces to find the best magnification for your target.

What should I do if the mount is unsteady during observation?

Ensure the tripod legs are fully extended and locked. Place the tripod on a flat, stable surface. Add weight or use a stabilizing accessory if necessary to reduce vibrations. Verify that all connections are secure.

How do I clean the Bushnell 788840 telescope's exterior surfaces?

Use a soft, damp cloth to wipe down the telescope's body. Avoid using harsh cleaning agents. For stubborn dirt, use mild soap and water. Dry the surfaces thoroughly to prevent moisture damage.
