Top Mistakes with RGB Filters
- Mixing filter brands: Causes color shifts and calibration headaches. Stick to one brand for consistency.
- Using same exposure for all filters: Red and green pass more light than blue, so adjust exposure times accordingly.
- Neglecting filter wheel calibration: Misaligned filters cause color fringing. Use a precision filter wheel and secure it well.
- Ignoring atmospheric effects: Blue channels can blur due to atmospheric refraction; compensate during stacking and alignment.
- Skipping calibration frames: Capture darks, flats, and bias for each filter to avoid artifacts and uneven illumination.
Following these tips will help you achieve sharp, well-balanced color images every time.
