Getting
started in amateur astronomy can be a bit confusing at first.
There are so many new terms ("right ascension," "declination,"
"aperture," etc.) and odd concepts (e.g. the higher
a star's magnitude, the fainter, not brighter, it will be).to
learn. There are old misconceptions to unlearn (e.g. "The
best time to observe the moon is when it's full." and "The
best time to observe is when it's clear, windy, and the stars
are bright and twinkling.") And there's inscrutable equipment
to learn to use (e.g. GEMs - German Equatorial Mounts, Barlow
lenses, and far more).
Fortunately there are some wonderful guide books for the beginning
amateur astronomer. Two of the very best are by well-known Canadian
amateur and astrophotographer, Terrence Dickinson. Together they
will give the beginner not only a solid grounding in what to look
for and how to see (and photograph!) it, but also how to have
a lot of fun observing and avoid common mistakes. They should
be taken in the proper order, however.
First comes Dickinson's NightWatch: A Practical Guide to Viewing
the Universe. It is designed to allow easy use at the scope
or with binoculars and so is spiral bound (to open out flat),
has stiffer than usual paper and easy-to-read type. It covers
everything the raw beginner needs to know, with helpful, experienced
advice delivered in a friendly, encouraging tone. You'll find
out about the basic scale of the universe, where we fit within
it, and how this governs what we can see at night. Basic binocular
and telescope types are covered along with advice on how to choose
and use a beginner's telescope to best advantage. There is a simple
beginner's sky atlas in the form of 20 sky chart's with easy to
follow directions to the brightest and easiest to view star clusters,
nebulae, and galaxies. There's an extensive section on viewing
the Sun, Moon, and planets with tips on low to train your eye
to see the most since experience (or an experienced guide) counts
for much. Lastly come chapters on special events and phenomena
(eclipses, comets & meteor showers) and a brief introduction
to photographing the sky. Nightwatch is for the "raw
beginner," and, in that niche, is probably The Best Introductory
Book. I wish I had written it myself.
Think of The Backyard Astronomer's Guide, by Dickinson
and fellow Canadian astrophotographer Alan Dyer, as the sequel
to Nightwatch, designed to help the amateur who has seen the Moon
and planets a few times, shown off the "easy stuff"
to the family and neighbors, and is now wondering what to do next.
It covers some of the basic information introduced in Nightwatch,
but in greater depth, and includes many of the subjects that the
"developing" (as opposed to the "beginning")
amateur will want to know about. Eyepieces, filters, telescope
mounts and polar alignment, and computer guiding, are all covered
in the same simple language of Nightwatch, but more comprehensively.
There is a section devoted to astrophotography, taking pictures
with or through the telescope, using both film and digital (CCD)
cameras. Astrophotography used to be an esoteric field for the
"extreme" amateur, but has become far easier with low-cost,
digital cameras. Amateurs today are producing beautiful images
with backyard telescopes that would have been beyond the capability
of the professional astronomers at Palomar twenty years ago. The
Backyard Astronomer's Guide isn't for everyone who enjoyed
and benefitted from Nightwatch, but for those who want
to go on, it's a marvelous way to "take the next step."
Both books are copiously and beautifully illustrated with pictures
taken by amateurs and filled with those "tricks of the trade"
that it would take a lifetime to learn on your own.
