Deepsky Observer's Companion tutorial
Part 1: Deep sky observing for the beginner

Just starting out in astronomy?

The following thoughts and suggestions on astronomy as a hobby have been adapted from an article by Alan McRobert (1994) in Sky & Telescope.

"The amateur astronomer has access at all times to the original objects of his study; the masterpieces of the heavens belong to him as much as to the great observatories of the world. And there is no privilege like that of being allowed to stand in the presence of the original."

Robert Burnham Jr.

Ransack your public library. "Astronomy is a learning hobby ... self-education is something you do yourself, with books, using the library."

Learn the sky with the naked eye. "Astronomy is an outdoor nature hobby. Go into the night and learn the starry names and patterns overhead."

Don't rush to buy a telescope. "To put a telescope to rewarding use, you first need to know the sky as seen with the naked eye, be able to find things among the stars with sky charts, know something of what a telescope will and will not do, and know enough about the objects you're seeking to recognize and appreciate them."

"The pleasures of amateur astronomy are deeply personal. The feeling of being alone in the universe on a starlit night, cruising on wings of polished glass, flitting in seconds from a point millions of kilometers away to one millions of parsecs distant ... is euphoric."

James Mullaney

Start with binoculars. Ease of use, cost and performance make binoculars the ideal 'first telescope'.

Get serious about map and guidebooks. "A sailor of the seas needs top-notch charts, and so does a sailor of the stars. Fine maps bring the fascination of hunting out faint secrets in hidden sky realms. Many reference books describe what's to be hunted and the nature of the objects you find. Moreover, the skills you'll develop using maps and reference books with binoculars are exactly the skills you'll need to put a telescope to good use."

Find other amateurs. "Self-education is fine as far as it goes, but there's nothing like sharing an interest with others."

When it's time for a telescope, plunge in deep. Don't skimp on quality. "The telescope you want has two essentials. One is a solid, steady, smoothly working mount. The other is high-quality optics ... You may also want large aperture (size), but don't forget portability and convenience."

"Two things fill the mind with ever new and increasing admiration and awe, the oftener and the more steadily we reflect on them: the starry heavens above and the moral law within."

Immanuel Kant

Lose your ego. "Astronomy teaches patience and humility - and you'd better be prepared to learn them ... The universe will not bend to your wishes; you must take it on its own terms. ... Most objects within reach of any telescope, no matter how large or small it is, are barely within reach. Most of the time you'll be hunting for things that appear very dim, small, or both. If flashy visuals are what you're after, go watch TV."

Relax and have fun. "Part of losing your ego is not getting upset at your telescope because it's less than perfect. Perfection doesn't exist, no matter what you paid. Don't be compulsive about cleaning lenses and mirrors or the organization of your observing notebook ... Amateur astronomy should be calming and fun. If you find yourself getting wound up over your eyepiece's aberrations or Pluto's invisibility, take a deep breath and remember that you're doing this because you enjoy it. Take it as fast or as slow, as intense or as easy, as is right for you."
