The Astronomical League (AL) is a national organization of amateur astronomers promoting astronomical education, outreach, observation, and science, while working with amateur astronomy clubs and societies like the Astronomy Club of Asheville. Members of our club are automatically members of the AL.
Check out the AL website which is loaded with resources and information related to astronomy observation, outreach and imaging.

Astronomical Society of the Pacific
The Astronomical Society of the Pacific increases the understanding and appreciation of astronomy by engaging scientists, educators, enthusiasts and the public to advance science and science literacy. Both professional and amateur astronomers are members of the ASP.
The ASP’s mission-based astronomy and space science education and public outreach activities work to promote science literacy through the enjoyment of astronomy. ASP is a recognized leader in the field of astronomy education.
The Astronomical Society of the Pacific coordinates and hosts NASA’s Night Sky Network – “astronomy clubs bringing the wonders of the universe to the public”.
Check out the many resources for astronomy education for all age and experience levels at the website link below:
Astronomy Resource List
The link below will provide you with an extensive list of resources for the amateur astronomer that includes websites, books, magazines, vendors, sky atlases and planetarium software: Resource List
An Astronomer Looks at Astrology
The Astronomical Society of the Pacific takes a good look at the many problems with the pseudo-science of astrology. Page 5 of this document best exposes the absurdities of astrology.
A Resource Guide to Astronomical Pseudo-Science
The Astronomical Society of the Pacific examines with a skeptical eye some of the claims at the fringes of science that seem connected to astronomy. These pseudo-science claims range from astrology to UFOs.

How to Start Right in Astronomy
The link below takes you to a great article by Sky & Telescope with good advice for those new to the field of amateur astronomy:
For a series of great short, informative, and printable articles from Sky & Telescope on many aspects of observational astronomy, use the link below:
Secrets of Stargazing
Here’s the perfect, compact, paperback, how-to book for those new to stargazing and telescopes. It’s loaded with practical advice with easy-to-understand explanations on equipment and about how, when, and what to observe. And it has great illustrations.
Celestial Observer (aka CalSKY) is the most complete astronomical observation and information online-calculator on this globe: make your own customized calendar with data for satellites, asteroids, comets, planets, sun, moon and more …
Understanding and Choosing Binoculars
What is the right pair of binoculars for you, and what does that “10×50” on the side of the binocular housing mean anyway? Choosing the right pair of binoculars can be confusing because you have to consider several factors including how steady you can hold them. The links below will help you better understand the factors to consider before making that binocular purchase as well as how to use and adjust your binoculars.
How to Choose a Telescope
The two links below will provide you with 2 well-written articles from the folks at Sky & Telescope that are loaded with information about the different types of telescopes, telescope mounts and decisions to be made in purchasing a telescope.
Telescope Image Orientation – Why Is Everything Upside-Down?
Learn why the image in your telescope appears incorrectly oriented and what, if anything you can do about it. Click here.
Telescope Eyepiece Formulas
Determining what eyepiece to use for a particular celestial object requires a basic knowledge of how to calculate the eyepiece’s power and field of view as used in your specific telescope. This one page document explains those “formulas” quite well.
Telescope Mounts and Polar Alignment
A telescope mount is as important as the optical tube itself. So which type of mount should you get? And how do you polar align and operate one of those German equatorial mounts?
The links below are helpful in answering these questions:

Collimation of your Telescope Mirrors
Properly aligned optics are important for a crisp view of celestial objects. The link below provides a good discussion and illustration of the process for a Newtonian Reflector:
For a guide to collimating your Newtonian or Schmidt-Cassegrain telescope without tools, see this procedure documented by the folks from Sky & Telescope at the link below:
Although there are numerous collimation tools, including laser collimators, the use of a relatively inexpensive “collimation cap” may be all you need to perform a reasonably precise mirror alignment for your Newtonian reflector. These caps are available from vendors at the link below:
How to Clean Your Optics
Keeping your telescope, binoculars and eyepieces in tip-top condition doesn’t have to be intimidating or time consuming. Read this excellent article by Gary Seronik with Sky & Telescope to find out more.
Using Digital Setting Circles with your Telescope
Digital setting circles (DSCs) make locating celestial objects in the night sky much easier, especially faint objects or when observing in light polluted areas. The Astronomy Club of Asheville presentation below tells you just how DSCs work and more.
An Introduction to the Gear of Astro-photography
The link below provides a great guide for folks both new to and experienced with astro- photography. This file is a large “pdf” file (10.6 MB) that you may open here and then save to your computer, but it takes a few moments to load.
A Full and Proper Kit (PDF format – 11MB)
A Beginner’s Guide to Night Landscape and Astrophotography
In this five chapter guide, you’ll learn everything you need to take great pictures at night. By using proper camera settings, gear, composition, and focal points, you will learn how to create properly exposed pictures of stars, nighttime landscapes, and the Milky Way.
CCD Astronomy – Imaging the Deep Sky
Astronomy Club of Asheville member Ken Westall gave this presentation at our December 2011 club meeting. It covers the basics of CCD astronomy imaging: the equipment, the proper set up, and the methods and techniques.
