The Altair Astro Premium Luminance UV/IR Cut Filter is designed for imaging with mono or colour CCD and CMOS cameras. 
Ideal for for colour or monochrome planetary imaging, colour or mono deepsky long exposures, and video astronomy.
Advanced UV/IR blocking coatings give small star sizes even with refractor optics, and AR (Anti Reflection) coatings reduce halo effects and internal reflections for more pleasing star images.
The Luminance UV/IR Cut filter is carefully matched to the other RGB and Narrowband filters in the range, with minimal overlap and a tight fit within the transmission ranges. This can be seen from the spectral graph and results in pure colours with maximum efficiency.
Premium filter features:
• Batch-tested for consistency.
• High quality dichroic/dielectric coatings. 
• Anti-Reflection coating to reduce star-halos - stackable.
• UV/IR block for imaging - star bloat reduction with refractors.
• Ultra-flat glass by Schott Germany.
• Precision CNC machined filter cell for strain-free mounting and freedom from tilt.
