By blocking specific wavelengths from sodium and mercury vapor streetlights, it dramatically increases contrast on deep-sky objects. This filter is engineered specifically for the Vespera optical arm, enabling you to capture detailed images of nebulae and galaxies even from a city or suburban backyard.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eReclaim Your Urban Sky: Targeted Na and Hg Wavelength Blocking\u003c\/h3\u003e\n\u003cp\u003eThis City Light Suppression (CLS) filter directly combats the effects of urban skyglow. It is engineered to block the most common wavelengths of light emitted by city lighting, specifically those from sodium (Na) and mercury (Hg) vapor lamps. By rejecting this artificial light, the filter darkens the sky background in your images, making faint deep-sky objects stand out with significantly improved contrast.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe Vespera Advantage: Automatic Filter Recognition\u003c\/h3\u003e\n\u003cp\u003eDesigned exclusively for the Vespera smart telescope, this CLS filter offers seamless integration. The filter's housing includes an electronic card that allows your Vespera to automatically detect its presence.

It selectively allows the primary wavelengths emitted by these celestial clouds to pass through, revealing intricate details and vibrant structures. Your Vespera can capture stunning images of targets like the Orion Nebula (M42), the Lagoon Nebula (M8), and the North America Nebula (NGC 7000) from locations where they would otherwise be washed out by light pollution.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the Vaonis CLS Filter improve my Vespera images?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Vaonis CLS Filter improves your images by selectively blocking artificial light from streetlamps, which is common in cities and suburbs.

These objects emit light at specific wavelengths that the filter is designed to pass, while blocking the surrounding light pollution. This makes it ideal for targets like the Trifid Nebula (M20) or the Rosette Nebula (NGC 2237).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the Vaonis CLS Filter to see the Orion Nebula (M42) from my city balcony?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, absolutely. The Orion Nebula (M42) is a bright emission nebula and an ideal target for the CLS filter. The filter will help suppress city skyglow, allowing your Vespera to capture more of the nebula's faint, extended structure and color, which would typically be lost in an urban environment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill the Vaonis CLS Filter help with imaging galaxies like Andromeda (M31) with my Vespera?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, it will.
