Explore Scientific's 82° eyepieces are essentially Ultra-Wide-Angle versions of their hugely popular 68° Series. Which is good because they deliver the same impressive optical characteristics, over a wider Apparent Field Of View. Suitable for use with telescopes f-ratios f5 and above.
Visually the 82° FOV, long eye-relief and foldable rubber eye-cup provides a remarkably relaxed and immersive experience, even when wearing eyeglasses.
Low dispersion glasses with high refractive index and anti-reflection multilayer coatings on all air-to-glass surfaces provide maximum light transmission and high contrast. Blackened lens edges and internal baffling also enhance contrast and minimise ghosting from internal reflections.
Sealed waterproof construction and an Argon gas-purged interior protect the eyepiece from rain or dew and and eliminates internal condensation to ensure the optics remain pristine.
The tapered nosepiece (1.25" or 2", depending on the model) provides peace of mind because the eyepiece is less likely to fall out of the focuser if the lock-screw loosens.
Together with my telescope I bought last year I also bought three eyepieces from this collection. I bought the 4,7mm, the 14mm and the 24mm eyepiece, and I soon found out that the 8,8mm would be a great addition. Sooner or later I am also planning on getting the 6,7mm. As you can probably tell I really like these eyepieces. They give a very wide field of view, which is very handy when you are observing planets at high magnification especially for me because I use a dobsonian telescope. This means fewer nudges per minute and more enjoyable sessions. The wide field of view also comes in handy when viewing deep sky objects. Object s such as the Pleiades through my 24mm is stunning! It fills most of the field of view, and the stars are almost a cold blue colour. My dobsonian is the skywatcher 250px which is f/4,7 and these eyepieces handle the optics very well, however some false colour and aberration is seen at the edge of the field of view. This really doesn't matter that much since you really won't be following an object all the way to the edge, trust me.The only reason for me not to give these eyepieces 5 stars is because of the short eye relief. If you are using GLASSES then I WOULDN'T RECOMMEND these eyepieces since you will never get to enjoy the whole field of view.If you are looking for some eyepieces that will last the rest of your life, then I would highly recommend these. As long as you take care of them then they will be your best friends.
Excellent quality views, with 9.25 SCT, and 120mm refractor. They bring out the best in the optics, with comfortable eye relief, should have bought them sooner.
I do like Explore Scientific eyepieces. I’ve been using two 68-degree eyepieces for over a year now (a 16mm and a 24mm), and I love both of them. I got the 8.8 (82-degree) for Xmas 2015 and was very keen to try it out.The 8.8mm EP just oozes quality from the moment you take it out of the box. Weighing 280g, it feels good in the hand, and isn’t so heavy it unbalances the scope.My scope is a Skywatcher 250PX, which, at f4.7 is pretty fast, and the 68-degree EPs do suffer from a little distortion around the periphery of the FOV. You do have to look for it, though, and in normal use it’s not noticeable. With the 8.8mm, I saw no distortion at the edges!The 82-degree FOV is amazing (tFOV is 0.60 in my scope)! On M42, the nebula fills the view (in the 250PX the EP gives x136 magnification), De Mairan’s nebula stood out brighter than I’d ever seen it, and the E & F stars of the Trapezium cluster were clearly visible. This was the first time I’d seen these smaller stars. I did a comparison with the 16 and 24mm EPs, and the 8.8 was streets ahead, in terms of contrast, clarity, visible structure, and the lack of distortion at the edge of the FOV.Speaking of contrast, it was noticeable how much darker the background sky was in the 8.8, and how much clearer and sharper the stars stood out. On the Owl cluster, for example, the difference was amazing, with the colours of the stars coming through.Observing galaxies was a revelation. I stared at M82 for ages, watching it drift slowly across the huge FOV without having to nudge the scope to keep up. Not having to move the scope, combined with the contrast and clarity, allowed me to absorb detail I’d never seen before.The only planet on view on the night was Jupiter, still too low for ideal viewing, and it actually looked much better with lesser magnification in the 16mm.Lunar observing isn;t really my thing, but, I have to say, I can’t wait to try the 8.8 on the moon. According to Stellarium, the moon should almost (but not quite) fill the FOV at x136 magnification. That’s got to be some sight!All in all, this is a cracking EP. Great contrast, magnification and clarity, amazing FOV, with no discernible edge distortion. Incredible value for the price.
