Product Info
Manufacturer Description
Even before the disappearance of the famed Baader Genuine Orthoscopics in mid-2012, Baader Planetarium sought to develop a set of true Planetary eyepieces that was accessible for any amateur - without breaking their bank. Foregoing fancy (and costly) cosmetics, the new Classic Eyepieces deliver where it counts - performance. Their sharpness and contrast rival other 'planetary' eyepieces costing much more. To achieve this performance and value, Baader drew upon their extensive in-house knowledge and experience, combined with optical designs and processes leveraged from Zeiss.
Features of the new Classic Eyepieces:
- Optical design and manufacturing specs based on the highly regarded Zeiss Jena 0.965" orthoscopics (not any Japanese or Chinese makes).
- Fully multi-coated: All air-to-glass surfaces are coated with Baader's HT MultiCoatings, specifically matched to each substrate.
- Excellent ergonomics: The innovative recessed volcano top provides clearance for eyelashes and enables a comfortably located eyepoint without the stray light problems of a full volcano top.
- Integrated winged folding rubber eyecup: Eliminates distracting stray side-light, enabling full concentration on the object, as well as providing a thermally insulating and soft non-scratching top surface (ie, for eyeglass wearers). Also outstanding for BinoViewing. Rubber eyecup may be folded down or removed, if needed .
- 52-deg apparent field of view (6/10/18mm Orthoscopics): Makes finding and centering objects at high powers easier than typical 40-45deg eyepieces.
- Blackened lens edges; Parfocal.
- Threaded to accept standard 1.25" astronomy filters.

Jul 30, 2019Amazing performance!
Pros: Cons: Comments:The Baader Classic Ortho eyepieces, better known as BCOs, are the new version of the legendary Baader Genuine Ortho. They come with the superb Baader's HT MultiCoatings, a wide (for an ortho it means wide indeed) field of 52º and an unbelievable transparence and contrast. The 10 mm eyepiece is perhaps the best of the BCOs trilogy: 6, 10 and 18 mm. O own all so I know what I'm talking about. The BCO 10 mm high transmission and contrast shows details fainter than other eyepieces even the most pricey ones. Every time I went over a DSO object and test this little beauty, I'm amazed of the details shown by it. I switch to other eyepieces of the same (or so) focal length and everytime this BCO beats them all!
Bottom Line: Would you recommend this item? Yes
Used with the Baader Q Turret barlow 2.25x you get an excellent match and a superb 4.4 mm with excelent eyerelief. Why buy a 4 mm ortho when you can use it with a Baader barlow?
Without any doubt I'd say it's a MUST HAVE ep. in any eps astronomer box!This review was provided courtesy of AgenaAstro.com
May 20, 2019Amazing eyepieces!
Pros: Cons: Comments:I own the Orion premium binoviewers so I decided buy a pair of the 6mm as well as a pair of the 10mm. These are REALLY great eyepieces! (whether binoviewing or not... I did both.) Really sharp details of both Jupiter and Saturn. I viewed both of these planets at around 3:00 AM (5/18/2019). The details on Jupiter really stood out! Also, this is rare even for me to see but I could even make out the surface details on Saturn as well. Usually the body of Saturn is just mostly washed out. Not this time! Really stunning views! As far as what I would recommend between the 6mm and the 10mm, It was too awesome having both! And I plan on buying the 18mm next! Looking at deep sky objects was a treat with these as well. That's why I'm purchasing the 18mm next. I wanted to see more deep sky objects but the 6mm and 10mm wouldn't allow it. Also, on a side note, I volunteer on public nights at my local observatory and I get lots of traffic (long lines) at my telescope. To try and show LOTS of people views of Saturn or Jupiter through one of these eyepieces would be a nightmare. The field of view and eye relief is just not enough. However, if you don't mind losing a little bit of detail and contrast in exchange for more field of view and a ton more eye relief, consider the Orion edge-on planetary eyepiece line. (I own a pair of the 9mm) They aren't quite as good as the Baaders, but the views are still amazing and much more comfortable. I hope this helps!

Apr 4, 2018Great eyepiece
Pros: Cons: Comments:I bought this to compare its planetary and DSO performance to some other similar focal length eyepieces, and this is top notch. Extremely sharp and contrasty with great transmission.
Bottom Line: Would you recommend this item? Yes
I am unable to spot any meaningful difference between this my beloved 11mm TeleVue Plossl, except this eyepiece has much more eye relief and is much more comfortable to look through.
M51 spirality stands out in sharp relief, I can hold threshold stars more easily than in other eyepieces, there is no glare at all from the moon (meaning internal reflections are well controlled - not something all eyepieces do well at this price point), there is minimal scatter introduced by the eyepiece, and lunar and planetary detail are tack sharp.
If you are considering any Plossl around this focal length (even a TeleVue Plossl), then get this eyepiece instead. Optical quality is just as good, but much more comfortable to look through.This review was provided courtesy of AgenaAstro.com
Jul 16, 2017What a Performer!
Pros: Cons: Comments:This eyepiece is a performer! It's super sharp, has a nice FOV and the build is excellent. The eye relief is fairly short but I don't care. The eyecups are also excellent!...the best orthos I've ever looked through.

Jan 5, 2015Nice but short eye relief
Pros:Lightweight,Compact,Accurate,Easy to Use,Quality Lenses,Strong Construction
Cons:Short eye relief
Comments:I really like my 18mm Baader Classic Ortho, so I gave the 10mm version a try. Both the 18mm and 10mm versions have a 50 degree AFOV compared to 42 degrees like other Orthos. The extra AFOV helps with planetary viewing in my non motorized, non computerized scope. The outer edge of the view is slightly fuzzy in my f/4 reflector, but that's to be expected from any Ortho with more than 42 degrees AFOV. I can live with that. What I can't live with is the short 8mm eye relief. Eye relief is just too short for me, even with the eye cup removed. I took away 1 star for that.

May 30, 2013Great 10mm Baader Orthoscopic
Pros:Easy to Use,Lightweight,As Good As The Expensives,Quality Lenses,Compact
Cons: Comments:I use this EP in my 102mm f/9.8 Refractor and f/11 14" SCT. Use mostly on planets and the moon. Nice and sharp and easy to use. Nice eye relief and top is nicely shaped to give room for the eye lashes. Can't wait to use in my f/15 Mak-Cass once it shows up. I don't have any fast scopes so I can't comment on that, but I really think that these EPs are meant for fast scopes anyway. Haves used them on small tight DSO and they're great.
