Celestron was founded by Tom Johnson whose first telescope design was a simple 6-inch reflector, built for his young son. He gradually progressed to making larger scopes in more sophisticated designs. Today, the Celestron company is an industry leader in designing and manufacturing optical equipment including telescopes (computerised and non-computerised), binoculars, spotting scopes and its accompanying accessories. Celestron's legacy spans 50 years, and has grown to enjoy recognition from amateurs to serious astronomers globally. The company seeks to remain innovative by growing its product offerings, while supporting science education around the world.
