Baader 13mm Hyperion Telescope Eyepiece


The New Baader Planetarium Hyperion 68° Modular Eyepieces offer world-class performance and unique photo-visual features at an unheard of price. No longer do amateurs need to spend more on their eyepieces than their primary instrument in order to get true high-end performance in a wide-field eyepiece. Not just a different branded version of their highly regarded cousins, the Hyperions have been totally redesigned to deliver better transmission, contrast, and useful new features. Baader Planetarium has worked hard to give the Hyperions the world's finest optical coatings, superb mechanics, and their unique multi-functional design.

As a visual eyepiece, we have found the Hyperions deliver superb sharpness and color fidelity across their 68° wide, flat-field, even in fast telescopes. In our own comparisons to our personal favorites, the Pentax XL, the Hyperions matched the Pentax in every regard, and at just over 1/3 the price! From their superb on-axis and off-axis sharpness, to their pitch-black high contrast field, the Hyperions really work. Viewing through a Hyperion is notably comfortable and relaxing, due to their forgiving eye-position, 20mm of eye-relief, and an optical design that is free of the annoying kidney-bean effect.

Baader Hyperion Eyepiece Highlights...

 

  • Consisting of 8 elements in 5 groups, the Hyperion optical design delivers outstanding sharpness and color correction over a true 68° wide field, along with a comfortable 20mm of eye-relief.
  • High grade water-white glasses are used throughout, to deliver a crystal clear view with low scatter and excellent color fidelity, free of the yellow or bluish coloration imparted by many other eyepieces. Use of high-index glasses delivers low distortion and astigmatism, even on scopes as fast as f/4.
  • Baader Planetarium has gone to great lengths to give the Hyperions the most advanced multicoatings ever used on amateur telescope eyepieces (please note: these are not the same coatings other manufacturers use on their similar clones of these eyepieces..). The Hyperion multi-coatings and coating equipment are proprietary to Baader and have been designed by German coating engineers specifically for the Baader Hyperions, and optimized for each of the glasses used. These coatings are applied with the latest thin-film German coating equipment, training, and process controls. The result are coatings that truly rival the best in the world - including the famous Zeiss Abbe Orthoscopic! The difference is clearly visible - users report that the Hyperions clearly show fainter stars and darker sky than the competitive clones.
  • The proprietary Hyperion housings have been engineered by Baader to incorporate careful opto-mechanical design and execution of internal baffling to eliminate stray light and ghost reflections. Uncapping the eyelens reveals a pitch black interior, with no distracting and contrast-robbing glints of light from unbaffled lens or metal surfaces. We call these our 'black hole' eyepieces.
  • Superb fit and finish. Eyepiece barrels are accurate to size, nicely machined, and hard-anodized.
  • Works in both 1.25" and 2" focusers. The 1.25" barrel is threaded for filters and kept short (0.94") to work well in binoviewers and spotting scopes. Baader's new housing incorporates a full-length 2" barrel (0.94" long) and provides a specially designed tapered locking recess. In addition, the Hyperion field stop locations have been re-designed and optimized to give the shortest focus position possible (important for binoviewer use).
  • Soft folding rubber eyecups work for both normal and eyeglass users. Each Hyperion comes with protective lens caps and leatherette storage pouch.
  • Accepts popular Astigmatism Correcting Lenses. The Hyperion eyelens housing is compatible with the full range of correcting lenses from ¼ to 3½ Diopters. Observers with any astigmatism will really appreciate this feature, no longer needing to wear eyeglasses to see stars as true pinpoints. The long 20mm eye relief of the Hyperions works particularly well with these corrector lenses, without forcing the observer to press their eye close to the lens in order to see the entire wide field.
  • Great for Binoviewing! We've tried most of the wide field eyepieces on the market that are suitable for binoviewing, and the Hyperions are at the top with the very best. When compared to some wide field eyepieces developed especially for binoviewing, we found the Hyperions were superior in every aspect: more comfortable view with better eye relief, smaller housing diameter at the eyelens gives more nose-room, better coatings (=better contrast), wider field, and half the cost. Our favorite wide field bino eyepieces are the 8/13/17/21mm Hyperions, plus a 24mm Panoptic (another great bino eyepiece). For ultra-wide fields, the Nagler Type 6 are a fine choice (strange for one vendor to recommend another, but we really like the TeleVues).
  • The Baader Hyperions incorporate some unique and innovative aspects, which are designed to make them the ideal projection eyepiece.
  • The optical design of the Hyperions enables them to work as an extremely sharp wide-field projection eyepiece for even large chip CCD and DSLRs.
  • The eyelens barrel has been provided with two different external threads, M43 and M54 (these are covered by the removable rubber eyecups). A complete system of adapter rings enables cameras to be directly (and rigidly) close-coupled for afocal projection, or variably extended for classical eyepiece projection imaging with our T-Adapter and Extension Tubes. A series of 16 threaded rings provides compatibility with just about every digital (CCD/DSLR) and videocamera made, even large and heavy 3-chip videocameras.
  • The front negative lens element is designed to be removed (and exposes an M48 2" filter thread). This converts each Hyperion into a longer focal length high-quality projection eyepiece, giving the imager two choices of focal length with each eyepiece.

Best EP's for the $$$
I own 3 of these EP's. (8mm, 17mm, and 21mm), and every one of them provides a very crisp & highly detailed view of whatever object you're looking at. You would be hard-pressed to find an EP this good, for the money. Try the 8mm on M15, and you'll be pleasantly surprised at the detail!

Scope: Celestron 6SE & Meade LX10 (8")

Yes, I'll admit, my TeleVue EP's provide a better view (obviously), but, some of them can cost as much as a used Honda Civic. Which might explain why I only own 2 of them. :) And in this economy, I simply can't justify spending $350 to $1000 PER EP, when the Hyperion line is almost as good.

Whether you're looking to upgrade your EP kit, and/or maybe you're just ready to take your telescope to the next level, without having to take out a 2nd Mortgage on your house? The Baader Hyperion line can't be beat. I've been at this hobby since the late 70's/early 80's, and I've owned (and still own) just about every brand of EP there is. I can tell you from personal experience that these are a great deal, you won't be disappointed with build quality (they're solid as a Sherman tank), and the views they provide are awesome.

Baader Hyperion 13mm
I bought this EP a month ago. I was looking to get a Nagler 13, but the $330 price tag was a bit steep so I decided to settle for 68 FOV and try this EP. For $130 I'm ecstatic with the performance. It's not a Panoptic, but it's close enough for me and the money savings was sweet.

Have the 8mm -- Will Buy More!
I own the 8mm model, and have looked through several other focal lengths. Superb transmission and sharpness, edge astigmatism and field curvature are almost nonexistent. The only thing that keeps it from a 5-star is a >10% barrel distortion that compresses the FOV near the edge. One effect of this is a greater true field than the AFOV would indicate! It's a minor drawback, and you have to look for it to notice it. In every other respect, it matches eyepieces 3x the price, both optically and in solid build quality! I'll be ordering the 17mm soon.

Excellent medium/high power with any scope
I currently own the 5, 8, 13 and 21 mm models (and saving for the 36 mm. I use them in my 3 small (typical urban observer telescopes: Meade ETX 90 mm f/14, and Bushnell 127 mm f/12 Maksutovs, and 80 mm f/5 short-tube doublet refractor (Vixen A80-SSWT. The Hyperions look and feel big on these small scopes, but that's just about it, you can very easily get to using them without problems of handling or balancing. Optically, they do great, very honestly delivering the wide field and ample eye relief stated in the specs, and all with very good illumination and contrast. The only optical drawback is some evident, but reasonably expected and tolerable, edge distorsion when using the 13 and 21 mm in the f/5 short-tube. This is manifested by coma and spherical distortion in the outer surroundings of the viewfield, noticeable starting from around 2/3 out of the center while in the larger central region, the image is still quite excellent. I have done Moon, planets, star fields, and brighter fuzzies with the Hyperions all of it very satisfying observing. I can only imagine how they deliver in larger scopes or darker skies, but my humble experience with my urban lot of small scopes tells me these eyepieces should do very fine indeed. If buying a small basic set of Hyperions, I may suggest geting the 13, 8, and 21 or 24 mm (in that order as perhaps the most generally useful with any scope. As for myself, I tend to use 21 and 8 mm with the Maks, 13 and 5 mm in the f/5. The 5 mm gets too dim and washed out (over-magnified in the Maks while the 21 mm gives too much urban sky glow, besides edge distortion, in the short-tube.

Great Alternative!
I own the 21mm, 13mm, 8mm Baader Hyperion’s and couldn’t be more satisfied! I have done side by side comparisons with eyepieces 2-3 times there cost and the Hyperion’s have nearly matched, matched and exceeded the views of the others especially in contrast. Why use $400-$600 eyepieces for public viewings and cringe when the sticky fingered child or makeup queen are next inline to view? My Nagler’s are still #1 but the Hyperion’s make a great alternative!

Hyperion 13mm
For the cost these eyepieces are an outstanding purchase and an excellent upgrade to the standard plossyl supplied with many telescopes. These eyepieces are used with quality dielectric diagonals. So far the eyepieces have been used only with my RC's though they will be tried with a 5 triplet refractor when it arrives. Under good seeing conditions Globular and Open clusters are sharply focused and resolved. Nebulas are great and many galaxies viewed are OK. Razor sharp views with lunar features, The Hyperion 13mm and 17mm eyepieces are my favorites, though I have a 3.5mm and 8mm as well. It will be interesting to try these for planetary detail in my 5 triplet refractor. Easily earns 4.5+ rating, with a 5 reserved for my Televue eyepieces. Highly recommended without reservations!
