Optolong Filters Clip Filter for Canon EOS APS-C L-Pro

This filter is designed to enhance the contrast of deep-sky objects while reducing the brightness of the sky background. It achieves this through a sophisticated transmission profile that allows the spectral lines of deep-sky objects to pass through while suppressing various sources of light pollution. Moreover, it effectively diminishes the unwanted sky background caused by atmospheric oxygen emissions, commonly known as "skyglow." Particularly valuable in areas with significant light pollution, this filter is versatile, suitable for both visual observation and astrophotography.

Unlike conventional filters such as UHC or CLS filters, which primarily target light pollution, this multi-bandpass filter minimally impacts color rendition. Hence, it is well-suited for capturing continuum sources such as galaxies, globular clusters, and reflection nebulae.

Key features include:

• Blocks UV and IR radiation (700 - 1100 nm)
• High transmission within the passband
• Minimal impact on color rendition
• High optical quality

It's essential to note that this filter should never be used as the sole solar filter.
