Hey guys,

I got the Plössl eyepieces from Svbony and wanted to do a little review about them.




You find them here:
https://www.svbony.c...yepiece/#W9101E

My set includes the 6mm, 12mm, 17mm and 25mm eyepieces.

If you look at the low price, then what you get for it is a really good product! I am pleasantly surprised. Forget cheap plastic eyepieces with cloudy lenses.
The "classic" plössel from Svbony are a real treasure. All made of metal and equipped with an foldable rubber eyecup.

All glass surfaces are fully multi-coated and the overall impression of the eyepieces suggests a valuable product.



The glass element diameters are as follows:
6mm eyepiece - 5mm glass element diameter
12mm eyepiece - 11mm glass element diameter
17mm eyepiece - 16mm glass element diameter
25mm eyepiece - 24mm glass element diameter





The weight of the eyepieces is:
6mm 44g
12mm 54g
17mm 67g
25mm 80g.

According to the website, the eyepieces have a 48 ° field of view. That doesn't sound like much, but if someone like me is a fan of orthoscopic eyepieces and just enjoys sticking to the eyepiece or doesn't want to entrust their children with an eyepiece of $ 300, then this is exactly the right eyepiece! Definitely a noticeable difference in picture and build quality next to simple plastic kit eypieces.

When looking through, I particularly noticed the bright image quality. I like it very much.


I held my cell phone against the eyecup of the eyepiece. The proportions of the pictures have not been changed. No image processing was done either.


I like the 25mm eyepiece the most. You can grab it well and the large opening and the good eye relief allow you to look through with glasses.



The 17mm and 12mm eyepieces also allow a comfortable look through (without glasses)

But now we come to the 6mm eyepiece. It gets a little more challenging here. In order to see the full field of view, you have to look VERY close to the glass element.
But you will be rewarded with a very sharp image that appears even brighter than with my Baader Classic Ortho 6mm!




I really like terrestrial observations with these eyepieces! Those who don't mind the narrow field of view are well served with these eyepieces. A good bargain for the price! 100%!

As soon as the Hamburg sky becomes cloudless again, I will be able to test the eyepieces on stars, planets and the moon. I'm very excited.


Thank you for your attention

I agree with you, I love all my Sv's and everything about them but there are some very, very expert fellow astronomers on here that will hate your great, educational post  Keep using them, they have quite a diversified selection to choose from and growing almost every day  PS  Your next stop may be one or two of their very capable zooms

Thank you for your review, it's a good thing to check out other products.  I have a illuminated eyepiece from them, I would give C- or D+ the quality is just not quite what I expected.  I figure that it should be problem free, just used for my alignment and had almost 50% failure rate with the illuminated eyepiece not working or after playing around got it to come on.  It's double cross hair and little rough in appearance, like small saw edge.  When it works it meets my minimal requirements, but when in the field it should work every time and any equipment that takes away my sky time I have to question.  One last note the batteries were new, had extra's always and changed them with the same issues.

Hey Mike, sorry to hear that. I never had an illuminated eyepiece so I can't give you any advice. That really sucks...

[LDW47]

Nice! How do you like the zoom lens?

The views are great, the workings are great, the quality is top grade  I have the 8-24, 10-30 and am waiting for their newer 7.2-21.6 to arrive any day  They are a great compliment, a change of pace to all my 2" & 1.25" eps  I use the 10-30 in my solar scopes as well

Thanks for the review. Good to know these are a good entry option.

We should be grateful that those "entry options" can be liftime eyepices for some hobbyists. Compared to former Huygens and Ramsdenen starter eyepieces today's average Plössln are like a premium offering. I have a vey expensive and mostly green lettered eyepiece case, but one should admit that in many scopes an average Plössl can be satisfying, especially to casual observers. They are a good baseline, with higher specifications having an exponential extra cost.

Btw, I'm now feeling bad for not handling my $$$ eyepieces with gloves. Well, in winter I do!

[f18dad]

I am anxious to learn more about their “Impressing”. Is this a new manufacturing technique?  Is the impressing what enables them to produce these eyepieces so inexpensively?

They won't be just ' entry options ' for too much longer  Stay tuned

That is a good price for Plossl. About half the price of mainstream brands.

The 25 looks pretty good. The 17, 12 and 6 have a seemingly high amount of distortion for narrow AFOV eyepieces. But it probably won’t be that noticeable looking at star clusters.

Brighter isn’t always better. Especially when used during daytime or looking at a bright object, it can indicate a lack of baffling. You just have to point it at a bright target like the Moon and see how sharp it is. That is the real test to determine if it is better than the Baader 6mm. Maybe it is. Not saying it isn’t. But give both some time under the stars and planets before you declare one the winner and sell the other.

that is a good advice. I will try it out on occasion. and then I report.

Your F/4.7 250mm dobsonian will be a good test of the optical qualities of these eyepieces

Nice review and photos.  I have a number of Svbony eyepieces and find them quite good.  

[Karida Wei]

Nice review! Waiting for the night review!

[SteveG]

These look exactly like the Orion Sirius plossls, and about half the price. Probably great down to about 12 mm. 

[Udderly Abducted]

These look exactly like the Orion Sirius plossls, and about half the price. Probably great down to about 12 mm. 

The main difference I can see is that these are supposedly fully multi-coated whereas the Orion Sirius are just multi-coated. I just bought the Svbony 32mm plossl. I got it because I assumed it was probably a GSO, but now I can see some subtle differences in the design. Is there a way to tell if these are truly fully multi-coated?

That’s my experience with my reticle eyepiece too (see my new thread on this topic). The Syvbony illuminator is the same junky one as on mine…and the Celestron and, and.

"I got it because I assumed it was probably a GSO"

 

 

GSO is not the same as SVBONY.  GSO is made in ROC and SVBONY is made in PRC.

I just thought it was a rebrand of the GSO.
 
Here's some pictures to compare, and from what I understand, the Apertura and Astro-Tech are GSO rebrands. I just noticed that if you really look, there's even subtle differences among the GSO and the rebrands. The main reason I thought the Svbony might be a GSO is because it claimed to be fully multi-coated. Now Svbony might make their own stuff, but I haven't been able to find that info.

No surprise that you haven't found that info because Svbony is just one of multiple re-branders. Read Don Pensack's post #35 here for the reference, he may know better. I suspect Svbony Polssls as well as many other products are most probably coming from Synta.

Thanks for the info! I figured they were probably a reseller like so many. And yeah, some of their products are definitely Synta. Their plossls mentioned in this thread remind me more of Synta now than GSO since they have a 17mm. It just got me that they claim fully multi-coated. I wonder if they really are or not. If anyone knows how to check, I would be more than happy to check my 32mm.

[Udderly Abducted]

I just checked my Svbony SV131 32mm and Orion Sirius 25mm plossls, and they both had the exact same reflections. Four reflections in total. Two were green, and the other two were white. I don't have a GSO plossl to compare. I did some research, and those white reflections make me think that the Svbony plossls might not be fully multi-coated. I don't have enough knowledge to say for sure, but if anyone can help, I would greatly appreciate it.

 

Edit: I just read that a plossl should have six reflections, so I just checked my Svbony again, and sure enough, there were six reflections. They were just way bigger than the others and I didn't notice them. So I know one was green, but the other was more yellow/green or white depending on the light. So at least three were green and two were white. Not sure about that other one.

White reflections are from the glued glass surfaces - 2 doublets, 2 white reflections. Nobody (except some Baader eyepieces) coating the glued surfaces. The other four green reflections are from  the coated lens surfaces, so six is the right number for fully multicoated Symmetricals. There are just few astronomy optics manufactures and I'm sure all Plossls/Symmetricals now are fully multicoated even though some vendors may not explicitly state that, IMO.  Synta is well known as Orion's supplier so the Sirius Plossls are highly likely made by Synta. No surprise if the Svbony Plossls are Synta's as well and differ by labels only.
