Harry Siebert Optics Standard 7mm
Harry has succeded in making a remarkable three element eyepiece that beats all other eyepieces in contrast and sharpness that i have ever used period. We are selling our naglers and panoptics for these have even sharper images and once you use them on planets or anything else for that matter no other eyepiece will do. I am getting sharper images in my scope than ever before. The 7mm nagler when barlowed wasn't nearly as sharp as the 7mm harry. I have used a lot of eyepieces but if harry ever quit making these widefield eyepieces there is nothing else i could get that would satisfy me. Harry is doing a great service to the hobby in making such a great widefield eyepiece a unheard of price. All i can say is get some and see for your self.

This is a very good high power EP . Some distortion in the outer 5% of FOV but otherwise a superb EP for the money .

Great Ep for the price! I love the large amount of glass! Don't feel like I'm looking into a pinhole. The image is very clear and sharp. Harry has a good one here!

Use this as my main planetary eyepiece in my 6" APO Refractor. It has made my UO ortho take a back seat. This eyepiece is sharper and brighter with blacker sky background than the UO 7mm. Harry is a joy to do business with and is now my custom eyepiece maker. To all the reviewers out there who say these would not win in the looks department, well you must be looking in the end. These eyepieces are good to look at, but I do not buy eyepieces to look but to look through. Very solidly bulit, and nice and black on the inside of the tube.

This is my new planetary eyepiece that is used with my 6" APO Refrator.
Also is a great globular cluster eyepiece with no coma seen at all. When
using this 7mm eyepiece and an APO Barlow at a power of 322x, M13 was fully
resolved with dark lanes being seen running through it. Jupiter is very sharp
with 8 bands and a lot of detail seen at 322x. It has made my 7mm UO ortho
take a back seat. Harry is a joy to do business with, and will be my eyepiece
maker from now on.

The Siebert 7mm performs very well in my Discovery 12.5" truss dob. Very good contrast and wide field of view.Edge sharpness suffers a little but I expected it on a fast dob. I compared it to very expensive eyepieces used in scopes similar to mine and found it to be a capable performer with a bright sharp image. I don't think you can go wrong with it.

I agree with the above comments. This is a very good eyepiece. I've just recently received it and haven't used it on planets as of yet. I did buy it mainly for globulars and am very happy with it. Actually for the price, its a 10. I did notice edge of field sharpness was off in my 10" f /4.8 scope, but I actually expected worse. I compared it with my Orion Ultrascopic 7.5mm on M13 and M92. I could not see any difference other the wider fov on the Siebert. I did enjoy the 65 degree fov on this ep. I am considering selling the Ultrascopic.

Had a chance for further evaluation on globular clusters. Siebert 7mm vs. Orion Ultrascopic 7.5mm. I did notice that I could see deeper with the Orion. This was noted only on dimmer globulars. On brighter ones did not notice a difference. Also had a chance to evalute looking at Mars. Did not note any differences in planetary detail. I'm keeping the Ultrascopic.

Harry Siebert Optics Standard 7mm
Excellent clarity and contrast, as good as or maybe a little better than my Meade eyepieces. The wide FOV, however, blows away my Meades by a long shot. This is evident in how relaxed my eye feels after extended viewing. I've read criticisms about their appearance, and yes they do look a bit homemade, but what difference does that make? I don't know about you, but I tend to use my eyepieces when it's dark, I don't see what they look like.

My only minor complaint is how they accept filters. The filter sort of snap in with a rotating motion, but I would prefer if the eyepieces were threaded. I've dropped a couple filters trying to remove them, luckily i didn't drop the eyepiece! Threads would make this safer.

Harry is a joy to do business with. He knows how to treat customers. I highly recommend trying a set of his EP's. I would give a '10' rating if it wasn't for the lack of threads for the filters. So, '9' it is!

I finally had a chance to use this eyepiece on my F4.5 10" newtonian at a good dark sky area near Bisbee AZ. Compared it to a Meade plossol and Orion Lanthium.
All three are nice eyepieces, the Orions Eyerelief is espescially nice. But on deep sky objects the Siebert really looks good. Images are brighter and show better color when there should be color. Another reviewer also remarked on comfort of use, while the eyerelief is a little short, though no worse than the Meade the Siebert just feels more comfortable.
Also the wide field at the magnification is a pleasure.
Another very nice eyepiece from Harry.

What a difference when comparing it to a 7.5mm plossl with my 102 f/10 and 150mm f/8 refractors. More sharper and more contrast on the Moon, not to mention the wider field of view. Going back to the plossl looks yuck.

I was really surprised when I had a look at Mars. Less false colour around the limb than the plossl. I had thought that the false colour was something I was going to have to live with - with my cheaper refractors, but better eyepieces dramatically improve things. Was I one happy camper.

Greater light throughput as well when comparing faint field stars and globulars. The globulars were also resolved better.

Also I like how user-friendly they are. No need to hold your eye in just the right spot to avoid annoying blackout. This will be a great help when showing non astronomers through the scope.

All this for similar money to the plossls.

I dont have much experiance with eyepieces but all i can comment on is how well made they are. The rubber casing is superb. All i can say is that they are a million times better than the MA eyepieces that came with my scope. For me they are a superb step up from factory standard eyepieces. Some people even sya they are comparable to more expensive eyepiecs!!!!

Great buy!

Great eyepiece. Short eye relief not a problem for me. (no glasses) FOV is great compared to 7.5 plossl. Very slightly elongated stars in EXTREME edge of field, but is not objectional in my 8" f/6. Also darker backgound and brighter images than 7.5 too. Can't wait for Jupiter and Saturn! Barlowed very nice too.
Now I want more as this is my first Siebert.

This is a wonderful eyepiece. Don't be fooled by the low price, be grateful for it. It will match up with the best around. I compared it with a Nagler 7 mm. and with an Orion Ultrascopic 7.5 mm. in an 80 mm. f/9 refractor and the Siebert had the best contrast of the three. No edge distortion is apparent at f/9. At f/9 it is the best of the three eyepieces, despite the absence of multi-coating. I did see some edge distortion in a 70 mm. f/6.9 refractor.

This review is pretty much a duplicate of my review of the 4.9mm Siebert elsewhere on this site.

I've had this eyepiece for several months now, and have had a chance to use it extensively in my 10" f/5 Dob and my 3.5" f/11 refractor, as well as in several scopes that belong to observing buddies, including 8" and 10" f/10 SCTs, 80mm and 90mm short tube refractors, etc.

I'm not quite clear on whether these ratings are intended to be relative, factoring in price, or absolute against other competing products. On a relative basis, this eyepiece at $45 deserves much more than a 10. On an absolute basis, compared against the best without consideration for price, it deserves an 8 or a 9.

In the slower scopes, f/8 and above, this eyepiece is sharp almost all the way to the edge, provides extremely high contrast, shows no discernable aberrations, and is very bright. In such scopes, I consider it equal to the Radian at less than 1/5 the price, other than its shorter eye relief (~7mm versus 20mm for the Radian). Given its wider field (65* versus 60* for the Radian) I'd have to call it a dead heat. Within the shared 60* field, the Siebert matches or exceeds the Radian in terms of image quality.

In the f/5 and f/6 scopes, the Siebert is just a half-step behind the Radian. In those scopes, the Siebert shows a bit more edge softness than does the Radian, although within the 60* field its performance is still very good.

If you need a high-power eyepiece on a budget, no question, get the 7mm Siebert. If you're less constrained on budget, I'd still recommend the Siebert if your scope's focal ratio is f/8 or above and if you don't need the longer eye relief of the Radian. Even with a fast scope, though, I think you'll be pleased with the Siebert, even not considering its price. Taking price into consideration, there's just nothing that can touch the Siebert.

I bought 5 different wide angle eyepieces from Siebert Optics, they are all excellent but the 7mm is my favourite.
This is my new eyepiece for higher magnifications. It replaces my 9.5 mm
Super Ploessl (100$ !!!). Despite the higher magnification of the Siebert
7 mm it offers a bigger FOV which is clear contrasty and almost sharp up
to the edge (up to 90% of axis in my f/7 Newton).
Eyerelief is short but bearable (without glasses). I am very satisfied with
this eyepiece and I will definitly keep it. Even without considering the price
it is definitly a 10!

Great eyepiece!!!! ive owned naglers, panoptics, axioms, & plossls of all types. this eyepiece is top of the line as far as optics are concerned! 65 degree field is crystal clear. i own a lx90 meade 8" goto scope & will never buy a $ 100.00 or more eyepiece again. dont take it from me, buy one, it dosnt cost more than 1/3 of the price of a low focal length high dollar eyepiece from meade or tv to convince you price dosnt always mean the best. it will not cost an arm and a leg to aquire top of the line optics. i mean this eyepiece is far better than the ones mentioned above. the craftmanship is a little different but hey optics is whats its all about right!!! if you are wanting to look at your eyepiece instead of looking thru it id recommend a meade or tv, but if your interested in planets, or deepsky objects siebert is the eyepiece to own. the thing about the filters is quite alright, there are no threads for the filters, but they press, & turn in the bottom of the eyepiece housing easily, very secure!! i personaly like it.

Finally had a chance to compare the Siebert 7mm eyepiece to a University Optics 12.5mm tonight. On an excellent seeing night the Siebert performed very well. Good resolution of Jupiter and the cloud belts. The contrast was good and only a shade below the UO. Construction is solid and the eyepiece is light weight. Looses a little clarity at the extreme edge, but the large FOV makes up for loss so it is not very noticable. Eye relief is tight, but I don't wear glasses so it is not a problem for me. Would recommend to anyone looking for an affordable eyepiece that performs well above average.

A good eyepiece in comparison to what else is on the market for similar pricing.
Nice FOV and comfortable eye relief, nice sized glass and construction is good aswell.

Very sharp ep, with excellent contrast.

On double stars, Jupiter, and Saturn, the ep consistently provides better sharpness and contrast than my 7mm Nagler, 8mm RKE (Very Sharp ep!), and kills the Meade Super Plossls, and Orion Sirius eps of similar focal length I used to have.

The 7mm Nagler has more consistant edge correction, but the Siebert is quite sharp through 90% of the field on my Pronto and DGM OA-4.

I no longer take my 7mm Nagler when I go out. While the AFOV of the Siebert is less and the edge correction not quite as good, the sharpness and contrast imporovement make the difference between a mushy double star split and a razor sharp split. Jovian bands display more detail, and the Jovian moons consistently resolve into disks (in OA-4), while the Nagler leaves them a little mushy.

I now have Siebert 21mm, 10mm, 7mm, and 3.9mm. They have replaced my much more expensive 7mm and 12mm Nagler, TV 20mm Plossl, Vixen 12.5mm Lanthanum, UO 12mm Ortho, and Meade 26mm Super Plossl. In fact, along with a TV 32mm Plossl, they are now the only ep's I take!

A real steal. Harry is doing us all a great service in providing these eps at such an affordable price.
