• How do I clean the lenses of my Bresser device?

  Clean the objective and eyepiece lenses only with the supplied cloth or a soft, lint-free cloth like micro-fibre. Do not apply excessive pressure to avoid scratching the coatings. For very dirty lenses, slightly dampen the cloth with spectacle cleaning fluid.

• What is the standard warranty period for Bresser products?

  The regular warranty period is typically 2 years from the date of purchase. This period can often be extended by registering the product on the Bresser webwebwerf.

• What should I do if my telescope image is not in focus?

  Look through the eyepiece at a distant object and slowly extend or retract the focuser (or upper telescope part) until the image becomes sharp. Adjustments may be needed when changing the distance of the object.

• Is it safe to use Bresser telescopes to look at the sun?

  No. Never look directly at or near the sun through this device, as it poses a severe risk of immediate and permanent eye damage or blindness. Children should only use the device under adult supervision.
