Olivon's 3.5mm 70° Wide-Angle Eyepiece provides an immersive observational experience with its 70° wide angle of view and anti-reflection fully multicoated optics. Its lens is configured with eight elements in five groups, and is parfocal with all other Olivon 70° eyepieces - so there will be little or no need to adjust the focus when changing between different size eyepieces in the same series. The eyepiece features a double-barrel configuration that allows it to fit both 2" and 1.25" focusers without the need for adapters, and its twist-up eyecup allows the eyepiece to be used comfortably with or without eyewear.

    3.5mm 70° Wide-Angle Eyepiece (2" / 1.25") is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Awesome High Magnification and Big FOV Short and sweet: great for low f ratio scopes with at least 6 aperture. Details: I purchased this eyepiece for 2 reasons- Planetary viewing and high magnification of star clusters. The telescope I am primarily using this with is a 6 inch reflector with a focal length of 750mm, f/5. It's an Orion AstroView 6 on an equatorial mount. For planetary, it is wonderful. If you are tired of getting something in your field of view and it drifting out too quickly, this is for you. I used to use a 3x barlow with a 9mm plossl (like having a 3mm) and it was like looking through a drinking straw. This Olivon gives me close to the same magnification, but the target is visible for much longer in the eyepiece. The optics are clear and crisp and the thing is rock solid. You get a lot more of the surrounding space around your target which makes the whole experience of using your scope much more enchanting and rewarding. I have yet to try it on an open star cluster, but I have no doubt it will show them in all their glory. I tried this with a 5 f/5 reflector, my AWB OneSky, and it worked fine, but it may be a little to heavy for that particular scope's focuser. It's also pushing the magnification limit of a 5. Yeah, it works, but maybe look for something like the ES 4.7mm for your 5 I wouldn't use this with a high f-ratio scope as the exit pupil will get very small and you'll see floaters and other nasty things inside your very own eyeball. I saw only a hint of this while looking at Jupiter with my 6 f/5 as was expected and it was not enough to bother me. This is an awesome eyepiece and I plan on using for many years, so I have no reservations about spending over $100 on it. The only problem is now I want to buy a whole set of wide field eyepieces.
