Bushnell 788945 Telescope F.A.Q.

How do I align the Bushnell 788945 Telescope properly?

To align the Bushnell 788945 Telescope, first ensure it is on a stable surface. Use the finderscope to locate a distant object, then adjust the main telescope's focus until the object is clear. Ensure both the finderscope and main telescope are pointing at the same object for proper alignment.

What should I do if the image through the telescope is blurry?

If the image is blurry, check that the focus knob is properly adjusted. Ensure the eyepiece is securely inserted and clean both the eyepiece and objective lens. Atmospheric conditions can also affect clarity, so observe on a clear night.

How can I maintain the optics of my Bushnell 788945 Telescope?

Regularly clean the lenses with a soft, lint-free cloth and a suitable lens cleaner. Avoid touching the lenses with fingers and always store the telescope in a dry, dust-free environment. Use lens caps when the telescope is not in use.

Why can't I see through my telescope during the day?

The Bushnell 788945 Telescope is designed primarily for nighttime observation. During the day, ensure the telescope is not pointed directly at the sun, as this can damage the optics and is dangerous to your eyes.

How do I transport my Bushnell 788945 Telescope safely?

Use a padded bag or case specifically designed for telescopes. Secure all moving parts and detach the finderscope and eyepieces if necessary. Handle with care to avoid jarring movements.

What is the best way to store my telescope when not in use?

Store the telescope in a cool, dry place. Use the dust caps on all lenses and eyepieces, and cover the telescope with a cloth or plastic cover to prevent dust accumulation.

How do I balance my telescope on the mount?

Ensure the telescope is properly attached to the mount. Adjust the counterweights until the telescope remains stable and does not drift when released. This ensures smooth tracking and prevents strain on the mount.

What should I do if the mount is not stable?

Check that all screws and bolts are tightened. Ensure the tripod legs are fully extended and on even ground. If the problem persists, consider using additional weights or a stabilizing mat.

How can I improve my telescope's image quality?

Use higher quality eyepieces and filters specifically designed for your telescope model. Avoid observing near bright lights and ensure your lenses are clean. A good collimation can also enhance image quality.

What should I check if my telescope's motor drive is not working?

Verify that the power source is connected and functioning. Check for any loose connections or visible damage to the drive system. Refer to the user manual for specific troubleshooting steps or contact Bushnell support for assistance.
