Both beginning and seasoned amateur astronomers, as well as casual stargazers, may find this Astronomy Reference Guide from Sea and Sky to be a helpful resource. Here, visitors will find a plethora of information to help budding astronomers get started, such as an extensive FAQ page covering the basics of various celestial bodies and astronomy in general, as well as a glossary of astronomical terms. There is also a quick guide to different types of astronomy equipment and a digital Messier Catalog of Deep Sky Objects, which explains where to find 110 of the most well-known galaxies, nebulae, and star clusters. For those who are a little deeper into this fascinating hobby, Sea and Sky's overview of different astronomy software may come in handy, and astronomers at all levels can make use of Sea and Sky's detailed calendar of upcoming celestial events that extends (as of this write-up) to the year 2030. Sea and Sky is the work of J.D. Knight, a Florida-based graphic artist and web designer by trade and an astronomy enthusiast who created this website "for the sole purpose of bringing the splendors of the seas and the wonders of the universe to members of the Internet community."
