STC Filters Multispectra Clip-Filter Nikon APS-C

Introducing the STC Astro-Multispectra filter, a versatile solution engineered to combat light pollution and optimize astronomical photography with Nikon DSLRs. This filter effectively mitigates the disruptive effects of artificial lighting, such as those from mercury and sodium street lamps, while preserving crucial nebula emission lines. By selectively allowing wavelengths associated with prominent astronomical features to pass through, including the Hydrogen-Alpha, Oxygen III, and Hydrogen-Beta lines, it significantly enhances the contrast of celestial objects.

Crafted with precision, the filter boasts a superior light transmission rate, surpassing 95% for key spectral lines emitted by nebulae. Utilizing Ion Beam-Assisted Deposition (IBAD) technology on robust Schott® B270 optical glass, it ensures enduring durability and effortless maintenance. Furthermore, the filter's double-sided NANO Anti-smudge coating not only repels water and grease but also maintains optical clarity in diverse environmental conditions.

Featuring a sleek matte black anodized frame with a Teflon coating, the design minimizes flare and simplifies installation and removal from your lens. However, it's essential to note that this filter operates based on interference principles, meaning its spectral characteristics may vary depending on the incident light. Therefore, direct exposure to intense light sources can impact image quality due to interference and reflection.
