Inside, a 5-element, 4-group optical system and a wide 40mm field stop maximize the true field of view, while the generous 24mm of eye relief ensures comfortable viewing for all observers.\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\u003eA 72° Window on the Deep Sky\u003c\/h3\u003e\n\u003cp\u003eDesigned for wide, contextual views, the SV136's 72° apparent field feels less like looking through an eyepiece and more like a porthole into space. The combination of the 34mm focal length and a 40mm field stop produces a massive true field of view, allowing you to frame large deep-sky objects like the Andromeda Galaxy (M31) or the North American Nebula (NGC 7000) in their entirety.\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\u003e5-Element Design for Sharp, Wide Views\u003c\/h3\u003e\n\u003cp\u003eTo control optical aberrations across its wide field, the SV136 uses a 5-element, 4-group lens structure. This advanced design corrects for issues like field curvature and astigmatism that can soften stars at the edge of the view in simpler eyepieces. Fully multi-coated optics ensure high light transmission and contrast, critical for resolving faint details in distant galaxies and nebulae.\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\u003eComfortable Viewing with 24mm of Eye Relief\u003c\/h3\u003e\n\u003cp\u003eWith a generous 24mm of eye relief, the SV136 is exceptionally comfortable for long observing sessions. This long eye relief allows eyeglass wearers to see the entire 72° field of view without having to remove their glasses.

The SV136's 72° field of view provides a significantly more immersive and engaging experience. This wider perspective not only makes large objects easier to frame but also enhances the feeling of being surrounded by the starfield, transforming your telescope into a true wide-field instrument.\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 is the SVBONY SV136 34mm eyepiece best for?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe SV136 34mm is designed for low-power, wide-field observation of deep-sky objects (DSOs).
