Instead of one very long exposure, many astrophotographers capture multiple shorter shots and stack them in software. Here's why stacking often wins:
- Noise reduction: Stacking averages out random noise, improving clarity.
- Avoid star trails: Short exposures prevent trailing without needing expensive tracking gear.
- Flexibility: You can discard poor frames and adjust total exposure by adding more shots.
Software like DeepSkyStacker or PixInsight makes stacking easy and powerful, helping you reveal faint celestial details with cleaner results.
