  • iOptron Super View 68° 30mm Eyepiece (2")

    The iOptron Super View 68° 30mm Eyepiece delivers an expansive window into the cosmos, combining a long 30mm focal length with a generous 68° apparent field of view. Designed for the 2-inch format, this eyepiece provides the low magnification needed to frame large deep-sky objects and easily locate targets in long focal length telescopes.

    30mm Focal Length and 68° Field: Your Finder Eyepiece for Deep Sky

    With its 30mm focal length, this eyepiece yields very low magnification, transforming your telescope into a rich-field instrument for sweeping the Milky Way. The 68° apparent field of view feels significantly more immersive than a standard Plössl, allowing you to fit entire star clusters like the Pleiades (M45) or the full extent of the Andromeda Galaxy (M31) into a single frame.

    This combination makes the Super View 30mm an excellent "finder" eyepiece. Instead of searching for faint objects through the narrow field of a high-power eyepiece, you can use its wide perspective to center your target before increasing magnification.

    The 2-Inch Barrel Advantage for Maximum Field of View

    The 2-inch barrel is essential for achieving such a wide true field of view at a long 30mm focal length. A smaller 1.25-inch barrel would physically vignette the light path, cutting off the edges of the view. This larger format ensures you see every bit of the 68° field your eyepiece is designed to deliver.

    • Deep Sky Scanning: The low power and wide field are ideal for observing large, faint nebulae like the North American Nebula (NGC 7000) or the Veil Nebula complex.
    • Compatibility Note: To use this eyepiece, your telescope must be equipped with a 2-inch focuser and a 2-inch diagonal. It is not compatible with telescopes that only accept 1.25-inch accessories.
    • Exit Pupil Consideration: In very fast telescopes (f/5 or below), the exit pupil produced by this eyepiece can become quite large. This may reveal the shadow of your telescope's secondary mirror, a trade-off for its expansive field of view.

  • What is the iOptron Super View 30mm eyepiece best for?

    The iOptron Super View 30mm is a low-power, wide-field eyepiece ideal for three main tasks: locating objects, observing large deep-sky targets like open clusters and galaxies, and sweeping across dense star fields like the Milky Way.

    How will the Super View 68° 30mm eyepiece perform in an 8" f/10 SCT?

    It's an excellent match. In a typical 8" f/10 SCT with a 2032mm focal length, the Super View 30mm will provide 68x magnification and a true field of view of approximately 1°. This is wide enough to frame the entire Andromeda Galaxy (M31) or the Orion Nebula (M42) with surrounding context, making it a superb deep-sky eyepiece for this type of telescope.

    Does the 2" barrel on the Super View 30mm eyepiece offer an advantage over 1.25" eyepieces?

    Yes, a significant one. A 1.25" barrel has a physical limit on the field of view it can deliver at long focal lengths. The 2" barrel of the Super View 30mm allows for a much larger field stop, which is necessary to provide a wide 68° apparent field at 30mm without vignetting (darkening at the edges of the view).

    Can I see the entire Pleiades (M45) with the Super View 68° 30mm eyepiece?

    Yes, in most amateur telescopes. For example, in a telescope with a 1000mm focal length, this eyepiece gives 33x magnification and a true field of view over 2°. Since the Pleiades (M45) cluster is about 1.8° across, it will fit comfortably within the field of view with room to spare.

    Is the iOptron Super View 30mm a good "finder" eyepiece?

    Absolutely. Its low magnification and wide field of view make it much easier to scan the sky and locate your desired target. Many observers start with an eyepiece like this to center an object before switching to higher magnifications for detailed views.

    Will I need a 2" diagonal to use the Super View 30mm eyepiece?

    Yes. This eyepiece has a 2-inch barrel and requires a telescope with a 2-inch focuser. For refractors and Schmidt-Cassegrain telescopes, you will also need a 2-inch star diagonal to connect it to your telescope.
