🛠️ Bonus Tips for Capturing Deep-Sky Objects

1. Use a Tracking Mount – Long exposures require precise tracking.
2. Plan with Stellarium – Free software to predict when objects will be visible.
3. Start with Bright Targets – M42 and M31 are beginner-friendly and rewarding.
4. Shoot from a Dark Sky Site – Reduces light pollution and increases object visibility.
5. Experiment with Filters – Narrowband filters help when shooting in light-polluted areas.
