Narrowband imaging can be tricky. Here are five mistakes to watch out for:
- Ignoring filter bandwidth: Using too wide a bandwidth lets in unwanted light pollution; too narrow can reduce signal strength.
- Not matching filters to your telescope: Fast telescopes need filters with better angle tolerance to avoid color shifts.
- Skipping calibration: Proper darks, flats, and bias frames are essential for clean images.
- Underestimating exposure times: Narrowband requires longer exposures to capture faint emissions.
- Neglecting post-processing: Combining and mapping filters properly unlocks the best colors and details.
Stay mindful of these to improve your narrowband astrophotography results!
