Sky and Telescope's Hot Astronomy Product for 2008! The 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 of Germany has worked hard to give the Hyperions the world's finest optical coatings, superb mechanics, and their unique multifunctional design.
As a visual eyepiece, the Hyperions deliver superb sharpness and color fidelity across their 68° wide, flat-field even in fast telescopes. In comparison to the Pentax XL eyepieces, 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, extra-large eye lens, and an optical design that is free of annoying 'kidney-beaning' and blackouts.
Some highlights of the Hyperion Eyepieces:
• Consisting of 8 elements in 5 groups (3.5mm - 21mm), the Hyperion optical design delivers outstanding sharpness and color correction over a 68° wide apparent field (65° for the 21mm). The Hyperion optical design has been chosen to deliver a exceptionally comfortable view, thanks to its 20mm of eye-relief, large eyelens, and a pupil free of the kidney-beaning and blackouts common in many wide field eyepieces.
• The new 24mm uses a different optical design and delivers outstanding performance over its 68° wide apparent field. It is totally free of blackouts and other annoying exit pupil behaviors, delivers long eye relief (17mm), virtually zero distortion, and is sharp to the edge even in fast telescopes. Its flat focal plane is particularly suited to very fast newtonians that use coma correctors. The 29mm field stop makes the 24mm Hyperion the widest 24mm eyepiece we know of. The 24mm Hyperion is also the smallest and lightest of the Hyperions.
• 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 Phantom Group 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.
• 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.
• All Hyperions accept popular Astigmatism Correcting Lenses (not available in the USA though). The Hyperion eyelens housing is compatible with the full range of correcting lenses from 0.25 to 3.5 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.
• Removable Negative Lens Element permits variable focal lengths using Baader's new 14mm and 28mm Finetuning Rings (sold separately). NOTE: The 24mm Hyperion is a different optical design and does not permit the use of Finetuning Rings to decrease focal length.
• Great for Binoviewing! Baader has 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, they 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. Their favorite wide field bino eyepieces are the 8/13/17/21/24mm Hyperions. The new 24mm Hyperion works superbly in binoviewers, and delivers the widest true field of any 24mm wide field eyepiece. Some users with narrow interocular separation may find it is necessary to remove the thin rubber M54 protective ring in order to increase the 'nose clearance'.
Baader Hyperions incorporate some unique and innovative aspects, which are designed to make them the ideal projection eyepieces for imaging applications:
• 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 wide variety of adapter rings enables cameras to be directly and rigidly close-coupled for afocal projection photography, or variably extended for classical eyepiece projection imaging with T-Adapters and Extension Tubes. A series of 16 threaded rings (sold separately) provides compatibility with just about every digital (CCD/DSLR) and video camera made, even large and heavy 3-chip video cameras.
• 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. NOTE: The 24mm Hyperion is a different optical design and does not contain a removable front element. However, the Front Barrel can still be removed in order to attach 2" filters in-between the 1.25" and 2" barrels. This is particularly convenient for users of 2" filters.

Great eyepiece but room for improvementPros:
Great FOV,Affordable PricingCons:
Dust Particles Internally,Need To Improve Mfg StepsComments:
I own a Skywatcher Heritage 130p dobsonian telescope. The eyepiece has been a wonderful addition to what I have. However, you have to pay attention to the weight of the eyepiece as you are pushing the limit of your telescope. This eyepiece allows you to view the sky at certain angles it seems. Your view will be blocked somehow and hence, you have to know where to position your eye. Another thing us that you may notice dust particles inside the eyepiece. It is especially noticeable when you view the full moon with it. Nothing can really be done about it untill Baader does something to rectify their QA during the assembly step. I noticed the same problem in my friend's 24mm hyperion too.

A lovely eyepiecePros:
Excellent Image Contrast,Quality Lenses,Strong Construction,Crisp Detailed Views,CompactCons:
For the money, this eyepiece is just the best! I have used it for astronomy as well as long range terrestial, and the detail and contrast are excellent. Nicely made, and I use it just about daily as it leaves my other eyepieces trailing behind one way or another...

I am very satisfied with the Hyperion 24Pros:
Accurate,Lightweight,Easy to Use,Compact,Quality Lenses,Strong ConstructionCons: Comments:
Not much to say other than I am completely satisfied with this and the 17mm I also bought. The 68 degree AFOV is more than good enough for my 71 year-old eyes. There may be a slight bit of edge distortion, but it may not be the EP, and in any event it's not objectionable to me in the least.

A Pleasure to UsePros:
Quality Lenses,Good coatingsCons:
I use this eyepiece with an 80mm f/7 refractor for terrestrial views, the moon, and as a finder scope. The views are sharp across the field with no color fringing. The 54mm thread atop the eyepiece makes for secure connection to a camera for digiscoping.

Very nice eyepiecePros:
Lightweight,No blackoutsCons: Comments:
I bought this after returning a competing wide field eyepiece that suffered from severe blackout without perfect eye placement. This eyepiece delivers nice views in an F/8 refractor and an F/5 reflector. It is very nearly free of blackout, and little coma was observed in the fast reflector. It is very light compared to competing eyepieces which eliminates the need to rebalance the telescope when changing eyepieces. Overall, it is excellent. I hope to acquire more Hyperion eyepieces in the future.

Comfortable,Good planetary performanc,Excellent overall opticsCons:
Poor thread blackening,Dust visible in focal pla,Field curvature at f5Comments:
I got this eyepiece from another dealer to compare with my 24mm Panoptic. My hope was that the 24mm Hyperion would offer a much cheaper alternative to the Panoptic for the max TFOV in a 1.25" format eyepiece. After some use, I found the results to be a bit mixed.
Upon receiving the eyepiece, I quickly noticed that the build quality was very good with the exception of the filter threads which were a bit poorly blackened. Viewing through the eyepiece during daytime, I noticed that I could see some small bits of dust which had accumulated on the field lens. Although the field lens is actually inside the eyepiece, it's easily accessible by unscrewing the lower assembly by hand. Using a simple hand blower, I quickly blew off the dust and everything was fine after that, although I would still need to re-clean it every once in a while after use in the field. It should be noted that I am near-sighted, so this issue of "dust in the focal plane" may not be a problem for everyone. And even so, it wasn't much of an issue during use at night.
With my f/5 12" Dob, I noticed significant field curvature in the outer 30%-35% of the field. Try as I might, I could not get a nice middle ground between the focusing in the outer field versus the inner field. Using a Paracorr seemed to help quite a bit. With the Paracorr, the field curvature was reduced to about the last 15% of the field, which wasn't too bad at all.
Overall, I was a bit disappointed with the eyepiece, but I didn't give up on it because I didn't see much wrong with the eyepiece beyond the field curvature issue. The contrast and sharpness at the center of the field seemed quite good and I saw only a little scatter and almost no lateral color. I had a 4X Powermate on order at the time and decided to keep the Hyperion a while longer. My hope was that it would make a nice planetary eyepiece for star parties when used with the Powermate.
It turns out that it was a very good idea. When used with the Powermate, the 24mm Hyperion gave great views of Saturn and Mars across almost the entire field of view. There was very little scatter, lateral color, or stretching of the planets at the edge of field. And the eye relief (listed at approximately 15mm) and comfort were top notch with good ease of use and no problems with blackouts.
Whether or not I can recommend this product is a tough question. I would say it's a definite "no" at f/5, but I would probably suggest people to try it out at f/6 and above.

24mm Baader Hyperion!Pros:
Quality Lenses,Comfortable Eyepiece,Strong ConstructionCons: Comments:
Just like all Baader products this EP is a great low power to add to your stable. While I bought mine used from an individual, Agena is great to deal with. In fact I just ordered the 8mm from them. The EP gives undistorted viewing to the edge with no aberation from what I can tell so far. The quality of these pieces are evident from the time you pick them up. They have a great following and you owe yourself to try one out and then you may be sold for life.

Lite Weight Wide FOVPros:
Quality Lenses,Strong Construction,Comfortable Eyepiece,AccurateCons: Comments:
Great views, flat FOV compared to most 68 degree 24mm eyepieces. No blackouts like I used to get from my Celestron X-Cells. And a Large exit lens. Fantastic views, great price. Try one and you'll be hooked. I now have the 24mm, 17mm, and 8mm. As soon as I can scrape up the cash I'll add the 13mm, 21mm, and the 5mm. These are the best eyepieces out there for the price. Fantasic contrast, easy to swap between 2" and 1.25 focusers. Very little coma for a 68 degree 24mm eyepiece even in my f4.5 scope, no coma I can notice in my f10 scope. And all the coma dissapears even in the f4.5 with a Paracorr. Buy one and you will want more. If you have a small scope (under a 8") start with this eyepiece. It is the lightest of their collection, so if it is pushing the balance of your scope the others will be heavier. These are big eyepieces and give you a BIG picture. You'll have to spend twice as much to get just a little better view. I sold my Meade 5000 wide view after getting this eyepiece. I reccomend the Hyprions over anything else out there anywhere near these prices. Yes 80 degree naglers are better, but you can get a whole set of these for the price of one of the Naglers.
