1. **Limited Effectiveness in Extreme Light Pollution** In heavily polluted areas (e.g., large cities with strong sodium or mercury vapor lights), the NGT-62 may not provide dramatic improvements, and additional filters (like a second-stage filter) might be needed.

2. **Not Ideal for Planetary Imaging** Unlike dedicated planetary filters, the NGT-62 is optimized for deep-sky objects (nebulae, galaxies) and may not enhance planetary details like Jupiter or Saturn.

3. **Potential for Slight Color Shifts** While it aims for natural color, some users report minor shifts in hue, particularly in red and blue channels, depending on the camera sensor or eyepiece used.

4. **Requires Proper Alignment** Like all filters, it must be correctly threaded and aligned to avoid vignetting or misalignment, which can reduce performance.

5. **No UV/IR Blocking** The NGT-62 focuses on light pollution reduction but does not block UV or IR wavelengths, which some astrophotographers prefer to filter out for sharper images.

6. **Thread Size Limitations** The 62mm size may not fit all telescopes or cameras, requiring adapters in some cases, which can add cost and complexity.

7. **Mixed Reviews on Contrast Boost** Some users find the contrast improvement modest compared to other filters, especially when used with high-sensitivity cameras or in very dark skies.
