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.

      5.0 excellent planetary eyepiece

      Pros:

      Cons:

      Comments:

      I have other high quality eyepieces but heard great things about these specifically for planetary and lunar observing. The detail seen through these are amazing and I am very happy I tried them out. The only downside I can tell is the short eye relief but if you don't wear glasses these are excellent for detail.

      Bottom Line: Would you recommend this item? Yes

      4.0 Good quality eyepiece

      Pros:

      Accurate,Strong Construction,Quality Lenses,Easy to Use

      Cons:

      Comments:

      This is a great quality eyepiece. I can see more moon crater details with this eyepiece than a 20mm Meade super plossl. The image is bright and sharp in the center, but a little fuzzy around the edges in my f/4 reflector. But the 52 degree AFOV more than makes up for that, compared to other narrower 42 degree AFOV Orthos or 45 degree RKEs. The edge fuzzieness goes away when I put this eyepiece in my 5x Explorer Scientific Focal Extender for 125x magnification.

      I wasn't sure about this eyepiece at first, but it's becoming one of my favorites. I like it so much, I bought the 10mm version too. I took away 1 star for 2 reasons. First, I didn't like the edge fuzziness at first. Second, I didn't like the winged eyecup at first either. But I'm getting used to it and it can come in handy.
