How do I clean my telescope optics?

Generally you should avoid cleaning telescope optics unless absolutely necessary. To avoid cleaning, you should always put on any caps/covers when not in use to prevent debris or dust from gathering on the optics.

For a refractor, you can clean the lenses with a lens brush or damp microfiber cloth.

For a reflector, clean the eyepiece lens with a lens brush or microfiber cloth, but we do not recommend trying to clean the mirrors as you could damage the reflective coating.
