    Many people ask us about various astronomy/astronomical terminologies. Words like Right Ascension & Declination, Celestial sphere, Celestial coordinates, Zodiac & Zodiacal light, Alt-Az, Parsec, Light Year, and Celestial pole; and the list goes on. Then there are the different types of telescopes. There are optical telescopes: refractors and reflectors. And there are different types of refractors and reflectors. Then there are telescopes which “see” in X-ray and ultra violet light. Solar telescopes use filters to “see” the Sun in varying wavelengths of light to see different aspects of the Sun. So, what do these words mean? Well, let’s take some time to explore these. In the coming weeks, we’ll not only define these words, but give you some educational information. And it will be entertaining. We’ll also have some free astronomy related stuff for the kids


We “get around” to several different venues and events during the year. We hope to see you at as many of these events as you can come to.

So why the name “Imperial”? That goes back to the early years of our home, Polk County, Florida. At one time, Polk County boasted more paved roads than anywhere else in the southeast U.S., hence the “Imperial” moniker. It was probably more of a P.R. thing than anything else, but the name has stuck. We are still officially known as “Imperial Polk County,” and are proud of our heritage. If you look alongside several of the old roads crossing the county line, you can still see some of the old county line markers that were installed in the 1930’s.
