Start Here: Beginner Astronomy

Welcome!
This is a curated stargazing for beginners guide focused on what to do tonight, what to look for, and what gear (if any) you actually need.
If you’re brand new to astronomy, this page is designed to get you productive fast without drowning you in options.
The goal is simple: help you figure out what’s in the sky tonight, where to look, and what you’re actually seeing — using a small set of reliable, beginner-friendly resources.
Use the sections below in order:
Plan tonight (sky map + planetarium)
Check conditions (clouds / transparency / seeing)
Find darker skies (light pollution map)
Learn the Moon & constellations (quick references)
Build your “next step” knowledge (one or two great books + a magazine)
Get help when you’re stuck (forums/clubs)
If you later decide you want deeper background reading, go to Astronomy Fundamentals
If you want “what’s visible tonight” tools and trackers, go to Observing & Sky Events (both are part of this Resource Hub).

Quick Start: What to Do Tonight
DO THIS- 1Check conditions (cloud cover + transparency/seeing). If it’s poor, don’t force it.
- 2Open a sky map and set your location/time (e.g., Stellarium Web).
- 3Pick one easy target (Moon, a bright planet, or a bright cluster/nebula).
- 4Go outside and observe: start naked-eye, then binoculars if you have them.
Common Beginner Mistakes (Avoid These)
AVOID- Ignore “600×” marketing. Stability and optics quality matter more than claimed magnification.
- Don’t expect astrophotography brightness. Many objects are subtle in real life.
- Start with high-reward targets. Moon/planets/bright clusters beat faint fuzzies early on.
- Give your eyes time. Avoid bright white light; allow 15–20 minutes to adapt.
- Most “broken telescope” issues are setup. Focus and finder alignment solve a lot.
Learn the Sky: Constellations & Sky Navigation
The Constellations (IAU) – A clear, authoritative introduction to constellations and how the sky is officially divided—great context before you start using star charts and planning tools.

Lawrence Hall of Science – Star Wheels (Planispheres) – Printable planispheres (“star wheels”) for different latitudes/hemispheres; an easy, hands-on way to learn the sky.
Tip: Prefer an interactive sky map? See Plan For Tonight → Stellarium Web below.
Plan For Tonight
Monthly Evening Sky Map (Skymaps.com) – Free monthly PDF sky map that shows the best things to look for this month, including planets, bright targets, and seasonal constellations.
Stellarium Web – Free browser planetarium: set your location and time, then learn what’s visible and where to look.
Heavens-Above – Excellent real-time sky chart and the best beginner-friendly tool for ISS/satellite pass predictions.
Timeanddate – Astronomy – Practical planning tool for twilight, Moon rise/set, and visibility timing for your location.
Sky & Telescope – Interactive Sky Chart – Interactive star chart showing constellation lines/boundaries and sky objects; great for learning the sky and confirming what you’re seeing.
Check Conditions
Clear Outside – Simple “go / no-go” astronomy forecast that highlights cloud cover, transparency, and seeing in one quick view.
