Bushnell 7887846 Telescope F.A.Q.

How do I align the finderscope with the main telescope on the Bushnell 7887846?

To align the finderscope, first set up the telescope on a stable surface. During daylight, point the main telescope at a distant object and center it in the view. Adjust the finderscope screws to align its crosshairs with the same object in the main telescope's view.

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

Ensure the telescope is focused properly by adjusting the focusing knob. If the image remains blurry, check for dirt or smudges on the eyepiece or objective lens and clean them gently with a lens cloth.

How can I maintain the optical components of my Bushnell 7887846 telescope?

Regularly check for dust and fingerprints. Use a soft lens brush to remove dust and a lens cleaning solution with a microfiber cloth for smudges. Avoid touching the lenses with your fingers.

What is the best way to transport the telescope without damaging it?

Use a padded carrying case designed for telescopes. Ensure all components are secure and avoid placing heavy objects on top of the case. Transport the telescope in its disassembled state if possible.

What should I do if the telescope mount is unstable?

Verify that all screws and bolts are tightened. Ensure the tripod legs are fully extended and locked in place on a stable, flat surface. Consider using additional weights or a sturdier tripod if necessary.

How can I improve my viewing experience in a light-polluted area?

Use a light pollution filter to enhance contrast. Focus on brighter celestial objects, such as the moon and planets, and try to observe from a location with minimal direct artificial light.

Why can't I see any stars through my Bushnell 7887846 telescope?

Ensure the telescope is properly focused and aimed at a bright star or planet. Check that the finderscope is aligned and there are no obstructions in the telescope's path.

What is the correct way to clean the Bushnell 7887846 telescope lenses?

Use a blower to remove dust, then apply a small amount of lens cleaning solution to a microfiber cloth and gently wipe the lenses. Avoid excessive pressure and direct application of liquid to the lenses.

How do I set up the telescope for astrophotography?

Attach a compatible camera using a T-ring adapter. Ensure the telescope is stable and balanced. Use a remote shutter release or timer to minimize vibrations, and consider using a tracking mount for long exposures.

How can I reduce dew formation on my telescope lenses during observation?

Use a dew shield to extend the tube length and prevent moisture from settling on the lenses. Alternatively, consider using a dew heater strip to keep the lenses slightly warm and free from condensation.
