Simulate the exact field of view of the SVBONY SV131 32mm 48° Plössl Eyepiece - 1.25" with your specific telescope.
Launch Visual AssistantThe SVBONY SV131 Plossl Eyepiece combines a 32mm focal length with a 48° apparent field of view, utilizing a 25mm field stop to deliver a wide true field in any 1.25-inch focuser. Its 4-element, 2-group optical design features fully multi-coated surfaces and provides a comfortable 19mm of eye relief, making it an excellent low-power eyepiece for extended deep-sky viewing sessions.
With its 32mm focal length, the SV131 delivers low magnification and a bright image, making it ideal for locating celestial objects and observing large-scale deep-sky targets. The 25mm internal field stop is near the maximum possible for the 1.25-inch format, ensuring you see the widest possible true field of view for framing entire open clusters like the Pleiades (M45) or sprawling nebulae like the Orion Nebula (M42).
The classic 4-element Plössl design is enhanced with Fully Multi-Coated (FMC) optics and matte blackened lens edges. This combination maximizes light transmission and eliminates internal reflections, resulting in high-contrast views where faint objects stand out against a dark sky background.
The SV131 is designed for comfort during long nights at the telescope, featuring a generous 19mm of eye relief. This allows most observers, including those who wear eyeglasses for astigmatism, to see the entire 48° field of view without strain. A soft rubber eyecup helps to position your eye correctly and block stray light.
Built from metal and optical glass, the eyepiece has a solid, durable feel. The barrel is chrome-plated for smooth operation in the focuser, and an eco-friendly rubber non-slip ring provides a secure grip, even with gloves on, preventing accidental drops on cold nights.
Compared to the standard 20mm or 25mm eyepieces often included with beginner telescopes, the SVBONY SV131 32mm Plössl is a significant step up. It offers a wider true field of view, making it much easier to find objects and appreciate large star clusters and nebulae in their entirety.
The SVBONY SV131 32mm is ideal for low-power, wide-field observing. It excels at viewing large deep-sky objects such as open star clusters, large nebulae like the North American Nebula (NGC 7000), and the Andromeda Galaxy (M31). It's also an excellent "finder" eyepiece for locating targets before switching to higher magnification.
In a typical 8" f/10 SCT with a 2000mm focal length, the SVBONY SV131 32mm will provide 62.5x magnification. This is an ideal power for framing the bright core and faint outer extensions of the Andromeda Galaxy (M31), making it a superb choice for this and other large galaxies.
Yes. The 1.25-inch barrel is threaded with the standard M28.5*0.6 pitch, making it compatible with all standard 1.25-inch astronomy filters, such as light pollution, nebula, or planetary color filters.
Absolutely. It is a very popular first upgrade. Compared to most 25mm kit eyepieces, the SVBONY SV131 offers a wider true field of view for easier object locating, lower magnification for brighter images of faint objects, and superior Fully Multi-Coated (FMC) optics for improved contrast and light transmission.
Yes, 19mm of eye relief is considered long and is very comfortable for most observers who need to wear glasses to correct for astigmatism. You should be able to see the entire 48-degree field of view with your glasses on.
Yes, it's an excellent choice for that purpose. The low power and wide field of view make the SVBONY SV131 32mm a perfect "finder" or "sweeper" eyepiece for a Dobsonian. It allows you to scan large areas of the Milky Way and easily star-hop to your desired target.
