The Antlia Quad Band Anti-Light Pollution Filter 2'' Mounted is engineered for astrophotographers seeking to capture deep sky objects from light-polluted locations. This filter is suitable for both color and monochrome cameras, enhancing contrast and signal-to-noise ratio for targets such as galaxies, emission and reflection nebulae, and star clusters.
Key Features
- Quad bandpass design transmits visible and near-infrared (NIR) wavelengths, improving performance with modern high quantum efficiency cameras.
- Optimized for use with fast optical systems up to f/2 focal ratio.
- Helps maintain natural color balance and simplifies post-processing.
- Best results are achieved with cameras featuring AR protective glass, allowing both visible and NIR signal capture.
Spectral Performance
- Passbands: H-alpha, S-II, O-III, H-beta, NII
- Peak transmission: greater than 92% for key lines
- Blocking: OD4 or better from 300–1050nm
- Filter thickness: 2mm ±0.05mm
