Stellarvue's Certified Pre-owned program is another benefit of ownership. Many of our customers upgrade to a larger telescope and trade in their lightly used Stellarvue telescope for one that is more advanced. We carefully clean, inspect, align and certify these pre-owned telescopes and offer them here with our full 2 year warranty. We guarantee they perform as new. Check back here often as these trade in's become available. There's no telling how fast they sell, could be days or even hours. Don't wait if you see something that catches your eye, it may not be here when you return.
