Optolong Filters L-Quad Enhance 2" (80320)

The L-Quad Enhance filter is a specialized quad bandpass filter designed to suppress light pollution for color cameras. By selectively blocking unwanted wavelengths, it provides better suppression of starbursts, increases image contrast, and reveals more details in celestial objects. The filter also enhances color saturation and delivers excellent performance in terms of signal-to-noise ratio. With a near-infrared cut-off up to 1000nm, it effectively reduces IR noise, resulting in cleaner and sharper images.

This filter is suitable for night skies ranging from Bortle 1 to Bortle 7, making it versatile for a wide variety of deep-sky targets while maintaining outstanding color balance.
