Optolong Filters L-Pro Clip Sony Full Frame V2 (79800)

The Optolong 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 wavelengths emitted by deep-sky objects to pass through, while blocking many common sources of light pollution. Additionally, it diminishes unwanted sky background caused by atmospheric oxygen emissions, often referred to as "skyglow." This makes the filter especially useful in areas with significant light pollution and it is suitable for both visual observation and astrophotography.

Color Rendition:
Unlike other filters intended to reduce light pollution, such as UHC or CLS filters, this filter is a multi-bandpass filter. It has only a minimal effect on color accuracy, making it ideal for photographing objects like galaxies, globular clusters, and reflection nebulae, which emit light across a broad spectrum.

Key Features:

• Blocks ultraviolet and infrared light in the 700 - 1100 nm range

• High transmission within the passband

• Minimal impact on color rendition

• High optical quality
