All TAAS and other new and not so new are welcome. What is the TAAS Fabulous 50 Program?

It is a set of 4 meetings events spread across a calendar in which a beginner to astronomy learns to locate 50 of the most prominent objects visible to the .

These include , , asterisms, and Messier objects. Methodology

1. Meeting dates for each season in year 2018

Winter Jan 19 Spring Apr 20 Summer Jul 20 Fall Oct 19

2. Locate the brightest and easiest to observe stars and associated constellations

3. Add new prominent constellations for each season Tonight’s Schedule

An asterism is prominent pattern or group of stars, typically having a popular name but smaller than a constellation. The Great Bear

Big Dipper Asterism Recognizing the Constellation Orion If you spot three bright stars in a row in the winter evening, you might realize, "Oh! That's part th of Orion!" 11 brightest

Suddenly, the rest of the constellation falls into place.

"There's BETELGEUSE in Orion's left shoulder and RIGEL is his foot."

8th brightest Once you recognize Orion, remember that his hunting dogs are following him.

Procyon is bright star in the constellation , THE LITTLE DOG.

Sirius is in the bright star in the constellation , THE BIG DOG.

Visible with telescope What Are the Messier Objects (M)?

The Messier objects are astronomical objects first listed by French in 1771.

Messier was a hunter, and was frustrated by objects which resembled but were not ,

He compiled a list of them to avoid wasting time on observing them

110 objects are in the catalog

Are the first deep space objects (outside of our ) that amateur astronomers will attempt to observe after observing the moon and the planets

All visible in small and many are observable in binoculars

Few visible to the naked eye The Messier objects are astronomical objects first listed by French astronomer Charles Messier in 1771. Messier Objects Messier was a comet hunter, and was frustrated by objects which resembled but were not comets,

Messier 42 How to use the Sky Map

Locate the four cardinal directions:

a. South b. North c. West d. East

As you observe, hold the chart so that the direction you are looking is at the bottom of the chart Our eyes take 20–30 minutes to fully adapt from light to complete darkness. They become 10,000 to 1,000,000 times more sensitive than at full daylight.

Use a dim red light to read your to preserve your night adapted vison.

1. Take a sky map with you to dark location

2. Look for Polaris (North Star)

3. Look from map – to – stars then stars – to – map

4. Begin with the brightest and easiest to find

5. When you get “lost”, revert to what you know and try again

GO FOR IT & HAVE FUN! END
