Why use a telescope?

1. Magnify Nearby Objects

Page 8: So you want to buy a telescope!

You can overdo magnification.

Page 9: So you want to buy a telescope!

Morel of the story

Do not purchase a scope whose chief advertisement mentions magnification…

Page 10: So you want to buy a telescope!

2. Resolving Power

Page 11: So you want to buy a telescope!

3. Light Gathering Power

Page 12: So you want to buy a telescope!

Basic Types of Telescope

Best Contrast

Refractors But You Will Pay More

Page 18: So you want to buy a telescope!

Bigger is better.Larger Lens or Mirror

Greater Light Gathering Power and Resolution

$$$$

Page 19: So you want to buy a telescope!

Triple the mirror or lens size

Gather 9x as much light
