STARFINDING AIDS STAR IDENTIFICATION The simplest way to learn the stars (at least the navigational ones) is to use a star chart such as is shown on the inside back cover of this catalog You simply go back and forth between the chart and the sky until you have them located and committed to memory But if you think other gadgets might be fun and helpful, here are some great choices THE SKY SCOUT Celestron Itʼs a bit pricey, but it is certainly the top of the line in star identification devices In fact, it can be thought of as a personal planetarium It not only identifies any celestial body at which you point it, but it tells you (visually and audibly) all about the body just as a planetarium director would This includes facts, history, trivia and mythology concerning the body or constellation Compact and lightweight (like a camcorder), it can go with you to any outdoor night event, and will provide hours of entertainment for you and others in your group Key features are: ● Identifies over 6000 stars, 88 constellations and many galaxies, nebulae and star clusters with a click of a button ● Provides comprehensive text and audio descriptions ● Tonightʼs highlights: a customized list of the 20 best objects for viewing ● Constellation Lessons: Take a guided tour through all the stars in a constellation ● Built-in Field Guide includes introduction to astronomy, glossary of terms, man-made space objects, help menu and comet guide ● Simple enough for all ages: just turn it on and itʼs ready to use ● High impact case with rubber armor makes it safe for worry-free outdoors use Sky Scout works by a combination of automatic GPS location and three axis sensors measuring gravitational and magnetic fields, in addition to its own extensive built-in digital astronomy database, to establish its current position This eliminates the need to consult star charts or to make adjustments for time and location changes it works in two ways: either point at a celestial body and receive the resulting information, or select the bodyʼs name in the menu and follow the on screen prompts (arrows) to center the body in the field of view Sky Scout is about the size of a paperback book, weighs less than one pound and comes with headphones, carrying case, hand strap, and a USB cable for connecting to a PC for downloading updates It includes a built-in SD memory card slot for additional future tours and updates (information about this is included) Size is 2.5x4x7 inches Power is from x 1.5v AA batteries (not included) which last for about hours 2-year

This clever, innovative, patented invention will solve all your problems This computerized handheld device with a built-in electromagnetic compass instantly finds and identifies objects in your night sky It is optimized for latitudes 30° to 50° north Hereʼs how it works: you pushbutton your way through several screens that program in the time, date, and your geographic location This orients its view to your perspective Now dial up a planet, star, or constellation you want to find Then like a Geiger counter it flashes a series of red lights and beeps to coax you into pointing at the body in question At the same time you are given a view of the surrounding stars in the area It also works in reverse Point at an unknown star, and it will identify it for you and again show you a map of the surrounding area with all the major stars identified on the back-lighted screen Press another button, and a constellation drawing will be superimposed around the stars Itʼs about the size of a light-weight laptop computer, and is powered by two “C” and four “AA” batteries (not included) List price $129.95 SW 3.5 lbs Night Navigator #2276 $89 A compact, handheld, easy-to-use educational
