How often has dust or lint ruined an observation session on your eyepiece or telescope? A seemingly harmless strand of hair scattered across your photos or astrophotography can require hours of cleaning in an image editing program, and a greasy fingerprint or smudge on the optics can cause an otherwise perfect image to end up in the trash. This is where the Celestron LensPen comes in, an optical cleaning device with dual functionality that is small and lightweight enough to fit in your telescope accessory bag or camera bag, ensuring it’s always on hand when you need it. The LensPen is two cleaning tools in one. One end features a soft brush for removing dust and other particles from any optical surface. The other end of the LensPen addresses smudges that cannot be wiped away. This device has a special cleaning tip that works without liquids, so it never dries out. A cap protects the smudge-removing tool when not in use, while the brush is safely stored inside the LensPen. When cleaning optics, it’s always best to start with the brush, even if you think it’s unnecessary. Carefully brush the entire surface and then check your work. If you spot streaks or smudges, remove them with the cleaning element by gently touching the surface. The Celestron LensPen is a fantastic tool for all your optical equipment, including eyepieces, telescopes, spotting scopes, binoculars, microscopes, cameras, lenses, and more.
