A group of dedicated amateur astronomers recently evaluated the new Orion refractor telescope. They found that it allowed them to see planetary details with remarkable clarity, which were previously only visible as indistinct shapes through their 10-inch (approximately 25-centimeter) Schmidt-Cassegrain telescopes. Despite the 10-inch telescopes having larger apertures and thus collecting more light than the 5-inch (approximately 12.5-centimeter) Orion, the astronomers concluded that any serious amateur astronomer should choose the Orion for planetary observation.
