This document discusses different types of telescopes including refractors, reflectors, and Cassegrains. It explains what to consider when choosing a telescope like magnification, resolving power, and light gathering power. Telescope mounts including equatorial, alt-az, motorized and GoTo mounts are covered. The costs of telescopes are addressed, noting reflectors offer best value. Examples of what members have done with telescopes like astroimaging and variable star measurements are provided. Recommended retailers are listed and an upcoming event is announced.

7. Why use a telescope?
1. Magnify Nearby Objects

8. You can overdo magnification.

9. Morel of the story
Do not purchase a scope whose chief
advertisement mentions magnification…

10. 2. Resolving Power

11. 3. Light Gathering Power

12. Basic Types of Telescope
1. Refractor

13. 2. Reflectors

14. 3. Cassegrain

15. Best Value For Your Money?
Reflectors

16. Most Compact?
Casssegrain

17. Best Contrast
Refractors

18. Bigger is better.
Larger Lens or Mirror
Greater Light Gathering Power and Resolution

21. Telescope Mounts
Equatorial
Easier for Amateur
Astrophotography

22. Alt-Az
Most Commonly Used
Cheaper

23. Motorized
 Track Night Sky as Earth Rotates
 Adds to the cost

24. GoTo Mounts
Computerized Pointing
Easier for Beginners
More Costly
