The Altair Astro Premium OIII 6.5 CCD filter set is designed for astro imaging with Mono CCD or CMOS cameras.
 
This OIII filter can also be used for visual observation of nebulae with apertures of 6-8” or more, providing extremely high contrast.
 
Buying the set allows significant cost savings as opposed to purchasing the filters separately.
 
Designed for monochrome imaging of nebulae. Eliminates light pollution by avoiding the light pollution wavelengths.
 
A 6.5nm to 7nm FHWM yields higher contrast compared to say 12nm FHWM filters. This allows better performance within heavily light-polluted urban areas, or for imaging faint objects. The emission lines of artificial lighting (mercury (Hg) and sodium (Na) as well as skyglow are completely suppressed, allowing for long exposures in urban conditions. 
 
Features precise and steep transmission curves with narrow pass-bands to ensure high image contrast. 
Aside from the high qualty Schott German glass and top quality coatings, these filters have some additional enhancements which make them ideal for your astro imaging application.
 
Advanced UV/IR blocking give small star sizes even with refractor optics, and AR (Anti Reflection) coatings reduce halo effects and internal reflections for more pleasing star images.
 
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.
