  • SVBONY SV136 34mm 72° Eyepiece - 2"

    The SVBONY SV136 delivers an expansive deep-sky experience, combining a low-power 34mm focal length with an immersive 72° apparent field of view in a 2-inch barrel. 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.

    A 72° Window on the Deep Sky

    Designed 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.

    5-Element Design for Sharp, Wide Views

    To 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.

    Comfortable Viewing with 24mm of Eye Relief

    With 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. For observers without glasses, it provides a relaxed, non-critical eye placement, reducing fatigue as you scan the Milky Way.

    SV136 34mm vs. a Standard Plössl: Why 72° Matters

    While a standard 2-inch Plössl eyepiece offers excellent on-axis sharpness, its apparent field is typically limited to around 50°. 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.

  • What is the SVBONY SV136 34mm eyepiece best for?

    The SV136 34mm is designed for low-power, wide-field observation of deep-sky objects (DSOs). Its 72° apparent field of view is ideal for framing large targets such as open star clusters, large nebulae like the Orion Nebula (M42), and galaxies like Andromeda (M31).

    How will the SV136 34mm perform on the Andromeda Galaxy (M31) in an 8" SCT?

    In a typical 8" f/10 Schmidt-Cassegrain Telescope, this eyepiece will provide low magnification (around 60x) and a very wide true field of view. This allows you to see the bright core of the Andromeda Galaxy (M31) along with its faint, extended spiral arms and its companion galaxies (M32 and M110) all in a single, immersive view.

    Does the 24mm eye relief on the SV136 34mm work well with eyeglasses?

    Yes, the 24mm eye relief is considered very generous and is ideal for observers who wear glasses. It allows you to position your eye at a comfortable distance from the lens and still see the entire 72° apparent field of view without vignetting.

    Can I use filters with the SVBONY SV136 34mm eyepiece?

    Yes. The eyepiece is equipped with standard 2" filter threads (M48 x 0.75) on the barrel. This allows you to easily attach nebula filters, light pollution filters, or other 2-inch astronomical filters to enhance your views.

    Is the SV136 34mm a good choice for viewing the Orion Nebula (M42) with a 10" f/5 Dobsonian?

    Absolutely. On a 10" f/5 Dobsonian, the SV136 34mm eyepiece will provide about 37x magnification and a very wide field. This is perfect for framing the entire Orion Nebula complex, including the Trapezium, the main nebulosity (M42), De Mairan's Nebula (M43), and the nearby Running Man Nebula (NGC 1977) all within the same 72-degree field.

    Is the SVBONY SV136 34mm eyepiece good for high-magnification planetary viewing?

    No, this eyepiece is not designed for high-magnification viewing. Its long 34mm focal length produces very low power, which is ideal for large, faint objects. For detailed views of planets like Jupiter and Saturn, you would need an eyepiece with a much shorter focal length (e.g., 5mm to 10mm).
