Bushnell 789470 Telescope F.A.Q.

How do I set up the Bushnell 789470 Telescope for the first time?

Start by assembling the tripod and attaching the telescope tube. Insert the eyepiece into the focuser and secure it. Use the finderscope to align your telescope with a distant object for initial calibration.

What should I do if the images through my telescope are blurry?

Ensure that the eyepiece is correctly inserted and that the telescope is properly focused. Check for any dust or smudges on the lenses and clean them with a soft, lint-free cloth if necessary.

How can I align the finderscope of my Bushnell 789470 Telescope?

During the day, point the telescope at a distant object and center it in the eyepiece. Adjust the finderscope until the same object is centered in its crosshairs.

What is the best way to clean the lenses of my telescope?

Use a blower to remove loose dust. Then, gently wipe the lenses with a microfiber cloth and a few drops of lens cleaning solution. Avoid excessive pressure to prevent scratching.

How do I maintain the Bushnell 789470 Telescope for longevity?

Store the telescope in a cool, dry place. Regularly check for loose screws and tighten them if necessary. Clean the optics occasionally and cover the telescope when not in use to prevent dust accumulation.

What should I do if the telescope's mount is shaky?

Ensure that the tripod legs are fully extended and locked securely. Check that all bolts and screws are tightened. If the issue persists, consider using a vibration suppression pad.

How can I find celestial objects using the Bushnell 789470 Telescope?

Use a star chart or a mobile app to locate celestial objects. Align the telescope using the finderscope and then fine-tune by viewing through the eyepiece.

What is the recommended eyepiece for viewing planets with this telescope?

A 10mm or 20mm eyepiece is recommended for planetary viewing, as it provides adequate magnification while maintaining image clarity.

How do I troubleshoot if my telescope's focuser is not working properly?

Check if the focuser knobs are obstructed or too tight. Ensure that the focuser tube is clean and moves smoothly. If necessary, lightly lubricate the focusing mechanism.

What can I do to prevent dew formation on my telescope lenses?

Use a dew shield to extend the length of the telescope tube, minimizing exposure to moisture. Consider using a portable dew heater for extended sessions in humid conditions.
