Certified Pre-Owned Refurbished

Explore Scientific Certified Pre-Owned

These Certified Pre-Owned items -- including telescopes and accessories --  have been thoroughly inspected by the Explore Scientific Quality Control Team to ensure the item meets our high standard of performance. The item is then repacked, often in a new box, and prepared for shipment.

Generally these items come from one of two sources: returned, often in like new condition; or, were traded in on another item.

Certified Pro-Owned items may have use marks, including surface marring, scratches, dents, dings and discoloration -- all wear and tear that is expected of an item that is pre-owned.

Certified Pre-Owned items carry the standard Limited One-Year Warranty on mechanical and optical systems; however, because these items are pre-owned, they DO NOT carry a cosmetic warranty.
