1. Provide new astronomers a list of 50 night sky
objects that can locate with the naked eye.
2. A list that will showcase the night sky for an entire year.
3. A list that the beginning astronomer will remember from one observing session to the next.
4. A list that once observed will be the basis for knowing the night sky well enough to perform more detailed observing.
Objectives

1. Divide the observing activities into the four
seasons: a. winter –Jan-Feb-Mar b. spring –Apr-May-Jun c. summer – Jul-Aug-Sep d. fall –Oct-Nov-Dec
2. Begin with the bright and easy to locate and identify stars and associated constellations.
3. Add the other constellations for each season.

4. Add a few naked eye Messier Objects.
5. Include planets as a separate observing activity.
6. Include the Moon as a separate observing activity.
7. Include meteor showers as separate observing
activity.

The Messier objects are a set of over 100 astronomical objects first listed by French astronomer Charles Messier in 1771.
Messier was a comet hunter, and was frustrated by objects which resembled but were not comets, so he compiled a list of them in collaboration with his assistant Pierre Mechain, to avoid wasting time on observing them.
The number of objects in the catalog is currently 110.
The Messier objects are the first deep space objects (outside of our solar system) that amateur astronomers will attempt to observe after observing the moon and the planets.
All of the Messier objects are visible in small telescopes and many are observable in binoculars.
A few are visible to the naked eye.
What Are the Messier Objects (M)?

Tonight’s process
1. We will first look at a “free” Skymap.
It can be downloaded at
http://skymaps.com/
2. Then we will examine each constellation and its bright star(s) in detail.
3. Observe outside.

The Evening Sky Map
We will examine how to best use the Sky Map
We begin by locating the four cardinal directions:
a. South
b. North
c. East
d. West
Next we will learn how to hold or “orient”the Sky Map as we observe.
It is very simple.
As you observe, you hold the chart
so that the direction that you are looking
is at the bottom of the chart.
We will now use the Evening Sky Map to find some objects in the night sky.
This lesson will use the Northern Hemisphere May Sky Map

Star hopping to find objects
1. Learning how to move from a know object
to an unknown object.
2. Looking for “geometric situations”
half-way between two visible stars is the object I want to view

So, how BIG is Arcturus?
How many EARTHS will fit into ARCTURUS?
109 EARTHS will fit into the SUN.
17,500 SUNS will fit into ARCTURUS.
Therefore, 1,900,000 EARTHS fit into ARCTURUS. 1.9 million
