The Antlia LRGBR+ Dark Series Filters 2.00'' Mounted are engineered for advanced deep sky astrophotography, providing a full-spectrum response from 390nm to 1000nm. These filters are sensitive to both ultraviolet and infrared light, enabling high signal-to-noise ratio and enhanced contrast in your images.
Key Features
- Full-spectrum design captures UV and IR light for broader sensitivity.
- Constructed from quartz glass for superior durability, thermal stability, and scratch resistance.
- High transmittance: B filter ≥95%, L, R, and G filters ≥97% for minimal signal loss.
- Red+ filter extends sensitivity into the near-infrared, capturing signals missed by standard LRGB filters.
- Out-of-band blocking to OD4.5 (0.005%) reduces interference and minimizes halos around bright stars.
- Ultra-thin filter cell minimizes vignetting and maximizes clear aperture.
- Black anodized finish with laser engraving for lasting identification.
Usage Notes
- Not recommended for solar imaging or night visual observation.
- Never look at the sun with this filter.
For best results, pair with Antlia SHO 2.8nm and 2.5nm Ultra Narrowband filters, which share the same quartz substrate and refractive index for improved parfocality.
