BEST BUY FIRST TELESCOPE...
Most club members tend to recommend Dobsonian type telescopes as a first scope. Dobsonian Telescopes are reasonably priced for the aperture, are rugged and easy to use. These are not usually sold in the Department Stores, but they can be found in any telescope store. The Dobsonian telescope looks much like a cannon on a swivel. You point it in the direction you want, and then look. There are no fancy bells or whistles to confuse the beginner, and you develop a better feel for the sky. The price for a 6" varies around $400 to $500. Some Suggestions For first Telescopes The 6" Orion Deep Space Explorer and the Meade Starfinder both sell for around $400, the 6" Celestron Starhopper has a few more features and sells for about $450. These scopes are great for children about 9

and up to use alone. For sm aller children, Celestron m akes a 4.5" Dobsonion and a com pany called "Stargazer Steve" (http://stargazer.isys.ca) sells a 4.5" kit scope you can build in an afternoon and use the sam e night.
Most telescopes come with a small finder scope that is usually the cause of a lot of frustration. W e recommend the use of a reflex sight for beginners. The "Telrad" is the most popular of these; it has no power or image reversal and shoots a red "Bulls Eye" into space. You put the Bulls Eye on what you want to look at, and then with a low power eyepiece you can usually find the obj ect quickly. There are Telrad maps you can purchase that show the Bulls Eye in relation to the bright stars. A crude but workable set of maps for the 110 Obj ect Messier Catalog of Deep Space Obj ects is on our web page at:

INTRODUCING AMATEUR ASTRONOMY... AMATEUR TELESCOPE MAKERS OF BOSTON
The Am ateur Telescope Makers of Boston, Inc. (ATMoB) is an am ateur astronom y club devoted to telescope m aking, observing, and the study of the stars. The ATMoB was founded in 1934 with the cooperation of Dr. Harlow Shapley at Harvard Collage Observatory. In 1973, the Bond Astronom ical Society, another long-standing club, m erged with the ATMoB m aking the club one of the oldest and largest general interest astronom y clubs in the country. W e m eet form ally every m onth (except August) to hear a speaker, to discuss club acti vities, and to just socialize. W e also m aintain a clubhouse with an observatory, workshop, library, and observing area in W estford, MA. Mem bership is open to all those interested in pursuing astronom y as a hobby. M eetings: Our m onthly m eetings are held at 8 p.m . on the second Thursday of the m onth (except August) at the Phillips Auditorium of Harvard-Sm ithsonian Center for Astrophysics. The center is located at 60 Garden Street in Cam bridge (see m ap on the last page). Visitors are always welcom e and free parking is available on the grounds. Clubhouse & Observatory: Our Clubhouse and Ed Knight Observatory are located on the grounds of the MIT Haystack Observatory in W estford, Massachusetts (to reach the clubhouse, see m ap on last page). It is officially open every Saturday, (except holidays, Full Moon W eekends, and during certain astronom ical events) from 7 p.m . to 12 m idnight. Visitors are always welcom e. Please contact one of the two clubhouse com m ittee m em bers who are on duty the night you decide to visit. W e will be happy to show you around our clubhouse and observatory or answer any questions you m ay have. Since the opening and/or closing of the clubhouse is subject to the varying weather conditions (especially in the winter m onths), please call ahead between 7 and 8 p.m . (978) 692-8708. Mem bership: Joining the ATMoB provides a special network with others who also enjoy astronom y as a hobby. Included in the yearly dues is a subscription to our m onthly newsletter, STAR FIELDS. Other privileges of m em bership include discounts on subscriptions to astronom y m agazines as well as books and telescope m aking supplies.

Observing the sky on a clear, starry night can be an enjoyable and even inspiring activity for people of all ages. It is an experience that is particularly rewarding if you observe from a suburban or rural location away from the glare of Boston lights. Using binoculars or a sm all telescope can also greatly increase your enjoym ent of the night sky. However no m atter where you observe from , or whether or not you have a telescope, exploring the m any aspects of astronom y can be an exciting hobby. It can be an activity shared with thousands of other am ateurs all over the world. These individuals have the interest, curiosity, and im agination to want to explore the m ysterious universe around them for the sim ple joy of it or to better understand their place in the schem e of things. The popularity of am ateur astronom y is not only due to its intriguing subject m atter, but also because it is a m ultifaceted hobby enjoyable on m any levels. Astronom y can be explored from your arm chair by reading about how astronom ers have probed the depths of space to learn the nature of the universe. You m ay pursue astronom y m ore actively by joining a local astronom y club like the Am ateur Telescope M akers of Boston and learning by direct association with other am ateurs. If you enjoy building things, you m ay want to fabricate your own optics and build a telescope, as m any am ateurs have done. However, if you want to begin observing im m ediately, you m ay decide to purchase a telescope or binoculars. The telescopic study of the Moon, planets, and deep sky objects such as star clusters, nebulae, and distant galaxies can be a challenging adventure. By adding a film or video cam era to a telescope, you can also learn to obtain striking astronom ical im ages. The m ore experienced am ateur astronom ers contribute scientifically to astronom y by searching for com ets and novae (exploding stars), observing sunspots and m eteors, or by regularly observing a class of stars known as "variables" to determ ine how their brightness varies with tim e. This data is of great im portance to the a stronom ical com m unity in exploring the nature of these objects. Just plain star gazing without optical aid is also a lot of fun. Making friends with the brighter stars and constellations, watching the seasonal changes in the sky, and observing the five naked eye planets and their m ovem ents is a fascinating activity. The occasional eclipse of the m oon or sun, an aurora display, or a m eteor shower adds extra excitem ent to visual observing.

Check out the web site at www.arunah.org There is lots going on there at other tim es of the year as well. A very active group. ABOUT TELESCOPES... The m ost popular am ateur telescope is the ref lecting type. It uses a precisely curved m irror as the m ain optical elem ent to collect light and form an im age. The m ost im portant criteria of an astronom ical telescope is its diam eter. The larger the diam eter of the m irror (or lens in the case of a refr actor type telescope), the m ore light is collected and the brighter the im age becom es. Typical am ateur telescopes are 4 to 8 inches in diam eter and m agnify the im age 50 to 200 tim es. To be useful, a telescope m ust be pointable while rem aining rigidly supported. If you want to own a telescope, you have three options: (1) purchase a com m ercial unit, (2) purchase com m ercially m ade optics and assem ble the rest of the telescope yourself, (3) grind and polish your own m irror and com pletely assem ble your scope. Option 1 m ay be the hardest to do if you are just starting. If you are not sure of the capabilities you want in a telescope, you m ay wind up purchasing a telescope too com plex for your skills. Even if you know what you want, and just buy the m ini m um needed, it could cost $400 - $500. The last two options will save you m oney and give you the pride and satisfaction of building a fine telescope. TELESCOPE BUILDING... W ith the exception of the second Thursday of the m onth, Thursday nights are Mirror Grinding Nights at our Clubhouse. If you want to build your own telescope, take advantage of the help from our experts who can show you how to m ake your own m irror.
