This is a list of large optical telescopes.For telescopes larger than 3 meters in aperture see List of largest optical reflecting telescopes.This list combines large or expensive reflecting telescopes from any era, as what constitutes famous reflector has changed over time.
They designated this series as Ultra Compact (UC), referring to their former one as 'Classic.' From 2009-2012 their telescopes ranged from USD 3000 for a 12.5 inch telescope, up to USD 12–15,000 for a 25-inch telescope. [8] [9] The company manufactured a limited number of 30-inch and 36-inch telescopes. [10]
