Check the listing for details. SVBONY SV240 2" Multi-Narrowband Galaxy & Nebula Filter + M42-M48 Filter Drawer. Condition: New, Made in China. Listed at 185.99 USD. A new galaxy and nebula filter intended for shooting not only nebulae, but also galaxies by the use of the transmittance around the near infrared region. 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.
