Designed for sharp, high-contrast planetary observation, the Maksutov-Cassegrain optical system uses a meniscus-shaped corrector plate and a borosilicate primary mirror with an aluminum coating and quartz overcoat. The optical system provides 94% reflectivity and supports detailed visual observation as well as planetary, lunar, and solar imaging when an appropriate solar filter is used.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli class=\"\"\u003e\n\u003cp class=\"\"\u003e\u003cstrong\u003eOptical
