1. Understanding the Challenge
Night sky photography has two main challenges:
**Light** — Stars are dim. You need to gather as much light as possible, which means wide apertures (f/2.8 or wider) and high ISO settings.
**Motion** — The Earth rotates, causing stars to trail across the frame in long exposures. For wide-angle shots, you can use the "500 Rule": divide 500 by your lens focal length to get your maximum shutter speed. Example: 500 ÷ 14mm = 35 seconds max.
**Location** — Just like visual observing, dark skies are essential. Use our [Light Pollution Map](/dashboard) to find Bortle 3-4 locations.
2. The Budget Astrophotography Kit
Here's a complete setup for under $500:
Sony a6000 (Used)
RecommendedExcellent low-light performance, interchangeable lenses, lightweight. One of the best values in mirrorless cameras.
Rokinon 14mm f/2.8 Wide Angle Lens
RecommendedSharp, fast, and affordable. The go-to lens for Milky Way photography. Manual focus only, which is actually fine for astro.
K&F Concept Tripod
Sturdy, lightweight aluminum tripod with ball head. Critical for long exposures.
Wireless Intervalometer
Triggers your camera without touching it (avoids vibration). Also does time-lapses.
3. Camera Settings for the Milky Way
**The Magic Settings:** - **Aperture:** f/2.8 (as wide as your lens goes) - **Shutter Speed:** 20-30 seconds (use the 500 rule) - **ISO:** 3200-6400 (start at 3200, increase if too dark) - **Focus:** Manual, focused on a bright star (use Live View and zoom in) - **White Balance:** 3900-4200K (brings out blues and purples) - **Format:** Shoot RAW for maximum editing flexibility
**Composition Tips:** - Include interesting foreground (mountains, trees, old buildings) - Shoot during astronomical twilight for natural foreground lighting - Frame the galactic core (brightest part of the Milky Way) as your main subject
4. Post-Processing Basics
**Free Software Options:** - **RawTherapee** — Open source, powerful - **Darktable** — Linux-friendly, great noise reduction - **GIMP** — General editing, layer support
**Basic Edit Workflow:** 1. Adjust white balance (cooler = bluer) 2. Boost contrast and clarity 3. Reduce noise (luminance noise reduction) 4. Boost saturation slightly 5. Dodge/burn to emphasize the Milky Way
**Advanced:** Stack multiple exposures to reduce noise and bring out faint details. Sequator (free, Windows) does this automatically.
