Learn amateur astronomy to find fifty objects in three months
Three months of clear nights, a free planetarium app, and one pair of binoculars gets you from "that's the moon" to finding fifty real objects under the sky on your own — the major constellations, the bright planets, a few star clusters, the Andromeda galaxy. About 30 hours of practice. Buy a telescope only after this stage. Most beginners buy one first and quit within a year.
3 months · ~30 hours · find 50 named objects with binoculars and a star map
1.Turn Left at Orion — Consolmagno & Davis
The canonical beginner book in amateur astronomy, in print since 1989 and now in its fifth edition. Spiral-bound so it lies flat in the dark, organized object-by-object with three views per page: naked eye, finder scope, and eyepiece. It tells you exactly where to look and what to expect to see. Every working amateur astronomer over forty owns this book.
~$30 spiral-bound
Cambridge University Press →2.Stellarium
Free open-source planetarium that shows your exact sky from your exact location at any time. Run it on a desktop the afternoon of an observing session to plan what's up; on your phone outside in red-light mode to navigate the sky. The web version works in any browser without an install. There is no reason to pay for a star app — Stellarium is better than the paid ones.

stellarium.org →3.10×50 binoculars, before any telescope
A solid pair of 10×50 porro-prism binoculars — Celestron Cometron, Nikon Aculon, or similar — is the right first instrument. They show you the moons of Jupiter, the craters of the moon, the Pleiades, the Andromeda galaxy, and most of the brightest deep-sky objects. They're easy to aim, light enough for hand-held use, and they survive a learning curve. A cheap telescope under $300 will frustrate you and gather dust. Binoculars do not.
~$80–150 for a decent pair
If you live in a heavily light-polluted city
If you're in inner Brooklyn or central London, deep-sky objects are mostly off the table. Refocus on the moon, planets, and double stars — all of which survive city skies. Replace step 3 with a small refractor on a sturdy tripod (a 70mm-80mm scope, ~$200–300), which gives you sharp moon and planetary views from a balcony. Plan one or two trips a year to a dark-sky site to see what the binoculars in step 3 would have shown you nightly.
Why this path
The fastest way to quit amateur astronomy is to buy a $400 computerized telescope and discover, in the dark, that you cannot find Polaris. Turn Left teaches you the sky as a place; Stellarium gives you a working map of it; binoculars let you go look. After three months of this, you'll know whether you actually want a telescope, and if you do, you'll know what to buy. Skip this stage and you'll be selling a Celestron on Craigslist by next year.
