Optolong Filters Venus UV-Filter, 1.25'' (59434)
228.28 $
Tax included
The Optolong Venus-U Filter is designed for capturing photographs, CCD, or video images in the UV-A range (320-400 nm), making it possible to observe cloud structures on Venus. This filter is intended for use with monochrome CCD cameras, provided the sensor’s cover glass and internal UV-IR blocker are removed to allow UV light to pass through. The same applies to mono DSLRs, which require removal of the built-in low pass filter. A specialized UV lens is also necessary for proper imaging.
Optolong Filters Clip Filter for Nikon Full Frame L-Pro (59454)
209.59 $
Tax included
This filter enhances the contrast of deep-sky objects while reducing the brightness of the sky background. Achieving this involves a complex transmission characteristic that allows the spectral lines of deep-sky objects to pass while suppressing various sources of light pollution. It effectively diminishes the unwanted sky background, known as "skyglow," caused by oxygen emissions in the atmosphere. 
Optolong Filters LRGB filter set 31mm (unmounted) (82629)
256.54 $
Tax included
The LRGB filter set is specifically designed for astrophotography with monochrome CCD cameras, allowing you to capture high-resolution color images of the night sky. Unlike color CCD cameras, which use built-in color filters that reduce resolution, a monochrome camera paired with LRGB filters utilizes the full sensor for each exposure. This results in brighter, sharper images of deep sky objects.
Optolong Filters Clip Filter for Canon EOS APS-C CLS-CCD (59443)
145.78 $
Tax included
The CLS (City Light Suppression) broadband filter is designed to enhance the visibility of deep sky objects by reducing the transmission of certain wavelengths associated with light pollution. It is particularly effective at blocking light from artificial sources such as mercury and sodium vapor lamps, as well as minimizing the unwanted 'sky glow' effect. The filter remains highly transparent to the main emission lines of nebulae, including OIII (496nm and 500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm), and SII (672nm).
Optolong Filters Clip Filter for Canon EOS FF CLS (59450)
145.78 $
Tax included
The CLS (City Light Suppression) broadband filter is designed to enhance the visibility of deep sky objects by reducing the transmission of wavelengths commonly associated with light pollution. It is particularly effective at blocking light from artificial sources such as mercury and sodium vapor lamps, as well as minimizing the unwanted 'sky glow' effect. The filter remains highly transparent to the main emission lines of nebulae, including OIII (496nm and 500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm), and SII (672nm).
Optolong Filters L-Pro Filter 77mm (73946)
252.33 $
Tax included
This filter is designed to enhance the contrast of deep-sky objects and reduce the impact of sky background interference, particularly in light-polluted areas. Achieving this involves a sophisticated transmission characteristic that allows the lines of deep-sky objects to pass while suppressing various sources of light pollution, including the atmospheric oxygen emissions responsible for "skyglow."
Optolong Filters L-Pro Clip Sony Full Frame (71253)
211.63 $
Tax included
This filter is engineered to enhance the contrast of deep-sky objects while reducing the interference from sky background. Its intricate transmission characteristics selectively allow the passage of deep-sky object lines while suppressing various sources of light pollution, including the unwanted atmospheric oxygen emissions causing "skyglow." Particularly effective in light-polluted areas, it serves both visual and photographic purposes.
Optolong Filters L-Pro Clip Sony Full Frame V2 (79800)
270.1 $
Tax included
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."
Optolong Filters Clear Sky Filter 82mm (69501)
247.49 $
Tax included
The Optolong Clear Sky Filter 82mm is a broadband filter designed to reduce the impact of artificial light pollution, such as that from streetlights, making it easier to capture clear and vibrant images of the night sky. This filter is especially useful for astrophotography, enhancing the contrast and natural appearance of celestial objects like galaxies, star clusters, and the Milky Way even in areas affected by moderate light pollution.
Optolong Filters L-Ultimate 1,25" (79624)
292.7 $
Tax included
This 3nm dual-band filter is meticulously crafted to significantly mitigate the impact of light pollution while isolating the emissions from nebulae into H-Alpha (red) and OIII (green-blue) wavelengths. By blocking light pollution and enhancing the signal from nebulae, it effectively darkens the sky background, providing optimal conditions for astrophotography. 
Optolong Filters L-Quad Enhance 2" (80320)
270.1 $
Tax included
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.
