Bushnell 789512 Telescope F.A.Q.

How do I properly align the finderscope on my Bushnell 789512 Telescope?

To align the finderscope, first locate a distant object through the main telescope. Then, adjust the finderscope screws until the crosshairs are centered on the same object.

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

Ensure the telescope is focused by adjusting the focus knob. Check that the lenses are clean and that the telescope is properly collimated.

How can I maintain the optical lenses of my Bushnell 789512 Telescope?

Clean the lenses with a soft, lint-free cloth and a lens cleaning solution. Avoid touching the lenses with your fingers and always store the telescope with lens caps on.

What is the best way to transport my Bushnell 789512 Telescope without damaging it?

Use a padded carrying case to protect the telescope during transport. Ensure all components are securely fastened to prevent movement.

How do I troubleshoot alignment issues with my telescope mount?

What should I do if the telescope does not hold its position and keeps slipping?

Check that all locking knobs are securely tightened. If the issue persists, inspect for any damaged or worn-out components and replace them if needed.

How can I improve the stability of my telescope on uneven terrain?

Use adjustable tripod legs to ensure stability on uneven ground. Consider adding a weight to the tripod base for additional stability.

What is the recommended procedure for collimating the Bushnell 789512 Telescope?

Refer to the manual for specific instructions on adjusting the primary and secondary mirrors. Use a collimation cap or laser collimator for accuracy.

How do I handle dew formation on the telescope lens during observation?

Use a dew shield to prevent dew formation. If dew forms, gently wipe the lens with a dry, microfiber cloth. Consider using a portable dew heater for extended sessions.

What should I do if my telescope's motor drive is not functioning properly?

Check the power supply and ensure the batteries are fresh or the power connection is secure. Refer to the manual for troubleshooting steps specific to the motor drive model.
