This kit effectively quadruples your magnification options by including a 2-element, 2x Barlow lens with M42x0.75 threads. A set of three filters—a Moon filter, an ND filter, and a #82A color filter—thread directly onto the eyepieces with a standard M28.5x0.6mm thread to enhance contrast on specific celestial targets.\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\u003eTwo 1.25\" Plössl Eyepieces: 6mm and 17mm Focal Lengths\u003c\/h3\u003e\n\u003cp\u003eThis kit is built around two versatile 1.25\" Plössl eyepieces, providing both high-power and medium-power views right out of the box. Both eyepieces feature fully multi-coated optics and blackened lens edges to maximize contrast and light transmission within their 48° apparent field of view. The 17mm eyepiece offers a comfortable 12.5mm of eye relief for general-purpose viewing, while the 6mm eyepiece pushes magnification for detailed views of planetary surfaces, though its 3.5mm eye relief is tight and requires close eye placement.\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 2x, 2-Element Barlow Lens\u003c\/h3\u003e\n\u003cp\u003eIncluded in the SV233 kit is a 2-element Barlow lens that doubles the magnification of any 1.25\" eyepiece.

The Moon filter reduces glare without altering color, increasing contrast on lunar maria and crater walls. The ND (Neutral Density) filter provides a more significant brightness reduction, useful for observing Venus or splitting bright double stars. Finally, the #82A light blue filter enhances low-contrast features on Jupiter and Mars, helping to define cloud bands and surface details.\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\"\u003eWhat objects is the Svbony SV233 accessory kit best for?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Svbony SV233 kit is designed for observing the Moon, planets, and bright double stars.
