ANTLIA 4-Channel Quad Band Astronomical Filter Anti-light Pollution Filter for Color Camera Support F2 Telescope
Description:
- The Quad Band Anti-Light Pollution Ultra Filter is a light suppression filter for OSC and monochrome cameras. It is able to shoot more objects in the visible to NIR spectrum range, like galaxies, reflect ion nebulae, emission nebula and star clusters from a Bortle 8 location to Bortle 1 by spectral transmission in the visible light spectrum, near-infrared and near-ultraviolet bands. When photographing full-spectrum galaxies under light polluted conditions, the Quad Band filter enhances the near-infrared signals, resulting in improved image contrast and signal-to-noise ratio while maintaining good color balance. Also, it has a broad bandpass designed to cope with faster optics up to the f/2 focal ratio.
- Considering the high quantum efficiency (QE) characteristics of the latest cameras in the near-infrared region and this region is less susceptible to artificial light pollution the Quad Band filter adds high transmission in NIR. This spectrum design improves image signal-to-noise ratio and contrast by capturing signals within this range while also facilitating color balance and easier to manage in post-processing.
- Please note that not all objects contain strong signal in the near-infrared (NIR) region. For instance, emission nebulae and planetary nebulae, which are typical examples of line spectrum objects, demonstrate limited signal in the NIR region. Conversely, certain full-spectrum objects like M51, M83 possess significant NIR signal, you can possibly shoot these objects more contrasted with the Quad Band filter. When using this filter with a camera that has UV/IR cut protective glass, the visible band Transmission signal is retained, which limits your ability to shoot targets with infrared signal. Therefore, the Quad Band filter is more suitable for cameras with AR protective glass as they can shoot both NIR and visible band signals.
