Considering the high quantum efficiency (QE) characteristics of the latest cameras (such as IMX585 and IMX464) in the near-infrared region and taking into consideration that this region is less susceptible to artificial light pollution, the filter adds high transmission in the near-infrared (NIR) band. This spectrum design improves the image signal-to-noise ratio and contrast by capturing signal in visible bands and NIR regions while maintaining good colour balance and being easier to manage in post-processing. Features: 1.Can be used to image most deep sky objects, including galaxies, reflection nebulae, emission nebula, and star clusters from a Bortle 1 location to Bortle 8. 2.Multi-Narrowband filter properly designed for astrophotography both in light polluted, allows for imaging in bright man-made light pollution and moonlit conditions. 3.Take color images without needing to combine images with multiple filter, most useful for One-Shot Color cameras 4.High transmittance of the main emission lines Ha\/OIII\/H-Beta in the visible region enhances SNR and contrast 5.Passing near-infrared region is for shooting deep sky objects that cannot be imaged with other filter without NIR transmission Tips: 1.The filter utilizing infrared tend to cause haloing in the NIR regions. This is because the anti-reflection properties of off-the-shelf cameras' optical systems (optical window and sensor cover glass) are optimized for the visible spectrum only, not for the NIR region. Thus, haoling at the camera end in the unoptimized region becomes more apparent, coupled with haloing from the filter itself. 2.The multi-narrowband filter is not suitable for visual observation and not designed for imaging or observing the Sun. 3.The filter is more suitable for cameras with AR protective glass as they can capture both NIR and visible band
