## Summary description

OWA Armor Vaonis CLS Filter for Vespera (MPN AC023) is an optical corrective lens filter designed for use with Vaonis Vespera telescopes. The CLS (City Light Suppression) filter reduces urban light pollution to improve contrast when observing or imaging nebulae and deep-sky objects. It mounts in the telescope optical path and is intended for astrophotography and visual observation in light-polluted areas.

## Long description

The OWA Armor Vaonis CLS Filter for Vespera is an optical corrective lens filter designed specifically for use with Vaonis Vespera telescopes. It is built to reduce the effects of urban light pollution by selectively suppressing common wavelengths emitted by streetlights and other artificial sources, improving contrast for visual observation and imaging of nebulae and other deep-sky objects. The filter mounts in the telescope optical path and is suitable for use during astrophotography sessions as well as direct visual viewing under light-polluted skies.
Advantages
This CLS filter increases contrast and detail visibility in deep-sky targets by attenuating wavelengths associated with common urban lighting while preserving transmission of wavelengths important for nebulae emission lines. It helps produce clearer images with less background glow and supports longer exposures during astrophotography by reducing sky background brightness. The filter is compatible with the optical design of Vespera telescopes, enabling straightforward installation without modification to the telescope hardware.
Suitable for
Visual observation of nebulae and deep-sky objects in urban or suburban environments
Astrophotography with Vaonis Vespera telescopes to improve signal-to-noise on emission targets
Reducing skyglow and improving contrast when observing from light-polluted locations
Key specifications
Filter type: City Light Suppression (CLS) optical corrective filter
Optical purpose: suppresses common artificial light wavelengths to increase contrast
Compatibility: designed for integration in the Vespera telescope optical path
Use cases: visual observation and astrophotography for nebulae and deep-sky objects
How to use
Install the filter in the dedicated filter holder or optical path position on the Vaonis Vespera telescope according to the telescope’s user instructions. For visual use, insert the filter before beginning observation and allow a brief period for the eye to adapt to the adjusted contrast. For astrophotography, mount the filter securely, frame the target, and use exposure settings appropriate to the reduced sky background; verify focus and framing after installation as the filter may alter effective contrast and perceived sharpness.
Usage recommendations
When observing from heavily light-polluted sites, combine the CLS filter with moderate exposure times and calibration frames for astrophotography to maximize image quality. Avoid stacking multiple strong light-reduction filters that could significantly alter color balance or reduce target signal unnecessarily.
