A Beginner's Guide to Astrophotography
Getting started in astrophotography is far simpler than most people think. You don't need a telescope, a tracking mount, or a specialized astronomy camera. A modern mirrorless or DSLR, a fast wide-angle lens, and a tripod is enough to capture the Milky Way on your first night out.

What you actually need
A camera with manual controls
Any camera that lets you set ISO, shutter speed, and aperture manually and shoot RAW will work. Full-frame sensors perform better at high ISOs, but APS-C cameras are perfectly capable for beginners.
Good starting points in 2026:
- Sony a7C II (~$2,200) — compact full-frame with excellent high-ISO performance
- Canon EOS R8 (~$1,300) — the most affordable Canon full-frame mirrorless
- Nikon Z5 II (~$1,500) — strong dynamic range, very forgiving at high ISOs
- Sony a6700 (~$1,400) — APS-C, lighter and more portable, still excellent
If you already own a camera, start with it. Upgrades come later.
A fast wide-angle lens
The lens matters as much as the body. You want wide (14–24mm on full-frame, 10–16mm on APS-C) and fast (f/2.8 or better). A wide field captures more sky; a large aperture lets in significantly more light.
- Sigma 14mm f/1.8 DG HSM Art (~$1,000) — the sharpest and fastest 14mm available
- Samyang/Rokinon 14mm f/2.8 (~$300) — budget-friendly and surprisingly capable
- Sony FE 20mm f/1.8 G (~$900) — excellent for Sony shooters, sharp wide open
A tripod
Any movement during a long exposure turns stars into blurry streaks. A solid tripod is non-negotiable.
- Vanguard Alta Pro 263AB (~$180) — stable, affordable, reliable
- Peak Design Travel Tripod (~$600) — premium, compact carbon fiber
Finding dark skies
This is the single biggest factor in your results. Light pollution from cities washes out the Milky Way completely. Even 60–90 minutes from most major cities puts you in meaningfully darker skies.
Use Light Pollution Map to find dark zones near you. Aim for Bortle Class 4 or lower — the green, blue, and grey zones.
Milky Way season in the Northern Hemisphere runs March through October, peaking May through August when the galactic core is highest and visible for the most hours each night.
The PhotoPills app (~$12) shows you exactly when and where the Milky Way core will rise and at what angle, overlaid on your shooting location. It's the most useful single planning tool for night photography.
Camera settings: your starting point
Set your camera to Manual mode and use these as your baseline:
| Setting | Starting value |
|---|---|
| Mode | Manual (M) |
| Aperture | Widest your lens allows (f/1.8–f/2.8) |
| ISO | 3200 |
| Shutter speed | 20 seconds |
| White balance | 3800–4000K, or Auto if shooting RAW |
| Focus | Manual |
| File format | RAW |
The 500 rule
Stars move due to Earth's rotation. Too long an exposure and they become short streaks. The 500 rule gives you a safe maximum shutter speed:
500 ÷ focal length = max seconds
At 20mm: 500 ÷ 20 = 25 seconds. At 14mm: 500 ÷ 14 = ~35 seconds.
On APS-C cameras, multiply your focal length by 1.5 first. A 14mm lens on APS-C behaves like 21mm: 500 ÷ 21 = ~23 seconds.
Focusing in the dark
Autofocus fails in the dark. Switch to manual focus, switch to live view, zoom in digitally to maximum on a bright star, and slowly turn the focus ring until the star is the smallest, sharpest pinpoint of light. Once focused, tape the ring so it doesn't shift.
Slightly soft focus is the most common beginner mistake — and it's invisible until you're back home reviewing files.
Your first shoot: step by step
- Arrive before dark — scout your composition in twilight when your hands and eyes work properly.
- Let your eyes adjust — 20–30 minutes minimum. Use a red headlamp; white light destroys night vision. The Black Diamond Spot 400 (~$45) has a good red mode.
- Point toward the galactic center — south in summer from the Northern Hemisphere. PhotoPills shows you exactly where.
- Take test shots — ISO 3200, f/2.8, 20 seconds. Review, zoom in on stars, check focus and exposure.
- Adjust from there — too bright: lower ISO or shorten shutter. Too dark: raise ISO. Too noisy: fix it in post.
- Shoot plenty of frames — 20–30 minimum. You'll use these for stacking later to reduce noise.
Basic post-processing
Always shoot RAW — JPEG compresses too aggressively and discards data you'll need in editing.
Adobe Lightroom (~$10/month via Creative Cloud) is the standard starting tool. The AI-powered Denoise feature added in 2023 is exceptional at high-ISO astrophotos. Push Exposure and Shadows, pull Highlights, increase Texture and Clarity, then run Denoise.
Free alternative: Darktable is a capable open-source RAW processor with similar functionality.
For stacking multiple frames to reduce noise, Sequator (Windows, free) is the easiest beginner tool — it automatically aligns and averages your frames while handling the moving stars separately from a static foreground.
What to shoot first
Start with the Milky Way core — it's the most dramatic and rewarding subject for beginners. Once you've got that dialed in, try:
- Star trails: shoot 30-second exposures continuously for 30–60 minutes and stack them in StarStaX (free)
- Constellations: wide compositions with foreground interest — even Orion over trees is a striking image
- The Moon: a great target for learning manual focus and exposure before tackling the full dark sky
The natural next step: a star tracker
Once you've captured the Milky Way, the next frontier is longer exposures without star trails — which means tracking Earth's rotation. A star tracker mounts on your tripod and slowly rotates your camera to compensate.
The Sky-Watcher Star Adventurer 2i (~$280) is the most popular entry-level tracker. It runs on AA batteries, fits any tripod, and opens up exposures of 2–5 minutes — revealing detail in the Milky Way and faint deep sky objects that a fixed tripod simply can't touch.
That's the jump to intermediate astrophotography — and the subject of our intermediate guide.
