DeltaOptical SuperView 30mm 68° 2″ eyepiece
If you are looking for an eyepiece that opens up a truly panoramic view of the night sky, the DeltaOptical SuperView 30mm is exactly what you need. With a wide 68° apparent field of view and a 30mm focal length, this eyepiece offers a noticeably more comfortable and spacious view compared to classic Plössl eyepiece series, where the field of view typically ranges around 50-52°. You will notice the difference immediately during your first look at nebulae, open clusters, or large galactic structures - objects simply "breathe" and you have plenty of space to observe their overall context against the starfield background.
Why choose a 2″ barrel?
The 2″ barrel diameter ensures that the eyepiece makes full use of the light-gathering power of your telescope. The larger barrel allows a wider light cone to be transmitted compared to the standard 1.25″ format, which - combined with the long 30mm focal length - directly translates into a brighter observed image. The DeltaOptical SuperView 30mm eyepiece is therefore particularly well suited for observing large deep-sky objects such as the Andromeda Galaxy (M31), the Orion Nebula (M42), large star clusters like M45 (the Pleiades), or extensive emission nebulae.
Who is this eyepiece designed for?
The SuperView 30mm will be especially appreciated by owners of Newtonian reflectors and apochromatic refractors with longer focal lengths, where it provides a comfortable low magnification with a maximum field of view. It is ideally suited as a "survey" eyepiece for initial sky orientation and object finding before switching to higher magnification. Technically experienced observers will also appreciate that the 68° field of view sits on the boundary between standard and ultra-wide-angle eyepiece systems - offering a very good compromise between field width, correction of edge aberrations, and an accessible price point.
SuperView vs. Plössl - a visible difference
The traditional Plössl eyepiece series is proven and reliable, but its 50-52° field of view can feel somewhat limiting during panoramic observation. The SuperView series offers more than 15° of additional field width without significantly compromising image quality towards the center of the field. For visual astronomers who enjoy "drifting" through star clusters or tracing the structure of large nebulae, this difference is very noticeable and contributes significantly to the overall observing experience.
