The Altair Astro Premium 7nm Ha filter is a must-have for astrophotographers seeking to capture the stunning details of nebulae with their Mono CCD or CMOS cameras. Designed to combat light pollution, this filter effectively blocks unwanted wavelengths, ensuring crisp and clear images. Its advanced anti-reflection AR coating minimizes glare and enhances the overall image quality. With the All-in-one Altair 2" Ha 7nm Filter Set [LnamzqIT], you can elevate your astro imaging to new heights.

Technical Specifications and Benefits

The Altair Astro Premium 7nm Ha filter offers a 6.5nm to 7nm FHWM, providing higher contrast compared to wider FHWM filters. This feature is particularly beneficial in heavily light-polluted urban areas, where it helps to suppress the emission lines of artificial lighting, including mercury (Hg) and sodium (Na), as well as skyglow. The filter's narrow pass-bands and steep transmission curves contribute to high image contrast, ensuring that faint objects are captured with clarity. The advanced UV/IR blocking coatings further enhance the star image quality, making it an ideal choice for refractor optics.
