Perfect for a dob telescope.
It was a much needed upgrade for my telescope.
Decent quality. Visibility is correct throughout the field.
I would buy it again if I had a choice. Good glass!
I have really enjoyed this set of eye pieces! They are of good quality and give excellent views of the moon, planets and deep space objects.
Possédant trois de ces oculaire le 9,15 et 20 mm excellant résultat d'image pour l'observation que ce soit avec mon Newton ou lunette 82 ED image très propre et pas déformé pour cela je considère excellent rapport qualité prix.
68° F.O.V. for a modest price, well corrected optics give nice clarity on Jupiter and Saturn, good eye relief distance for eyeglass wearers. I like the barrel detente for the focuser setscrews to secure the eyepiece when slewing scope past vertical. Retractable rubber eyecups provide good shielding of outside stray light. Nice esthetic look with anodized rings. Very happy with this set at an affordable price.
Got the 6mm. Great quality/price, great FoV but has the "kidney bean" effect that such eyepiece type produces. Also not very suitable in a small F4 newton scope, since it seems showing more coma than others EP like the plossl or super plossl from SvBony. Maybe better with other telescopes.
These ultra-wide eyepieces are incredible when compared to the eyepieces that come with the telescopes. At least that was the case with the 2 previous store-bought telescopes I have. Not only is the view brighter/wider when viewed through the actual eyepiece but the view out of the business end of the telescope is so much brighter/wider. What do I have to compare this to? Well, I said I have 2 relatively cheap refractor telescopes. In BOTH of those telescopes, I tried a 1.25 62 degree wide 6mm eyepiece. This one was bought by the same company for $11.00. I thought it would work great with these cheaper telescopes. I was wrong. It is these 2 telescopes that made me a believer out of this more expensive, yet reasonably priced eyepiece ($39.95). Keep in mind that BOTH 6mm eyepieces are from the same company, SVBOY. It's just that one is 6mm wide and the newer one is 6mm ultra-wide. It is the ultra-wide that outshined the 6mm wide eyepiece. The scopes I tested them out on are as follow:
SCOPE 1: MAXX Explore - 70mm with a focal length of 400mm
SCOPE 2: National Geographic Travel Scope 60mm with a focal length of 360mm
If they work great on these lower-end telescopes I can only imagine how much better they will work on larger telescopes. I am 100% satisfied. GREAT JOB.
Btw, I own several ED refractors, including a Stellarvue 80ED and a Televue 85 along with a 127mm Maksutov, and among the eyepieces I use with all of them are SvBony 68-degree APOV 6mm, 9mm, 15mm and 20mm (the red and black ones) and ALL of these are every bit as sharp and contrasty as my Explore Scientific EPs in the same or similar size. Hard to believe….but TRUE. And my SvBony 2x Barlow is actually BETTER than two “brand” name units I also own. You guys make some great gear.
I have used the 15mm for a long time now, and it is my most used eyepiece, along with the 32mm Plossl. As with other Svbony products, the construction is fantastic. I wouldn't say these are any wider than the 66 degree gold eyepieces, but I also wouldn't say they're optically identical otherwise. The rubber grips are a handy addition.
These are great eyepieces for planetary observing, or for slower telescopes. The 20mm gives an immensely immersive view.
All of these have a bit of edge softness in a slower telescope, but nothing to hinder the view.
