Coma-Correcting Eyepieces
For passionate stargazers the search for optical perfection is never-ending. Whether you are observing the stunning spirals of distant galaxies or admiring the intricate beauty of a globular cluster, you want nothing but the sharpest, clearest image your telescope can offer. However, anyone using a Newtonian telescope is likely familiar with a common optical challenge: coma. This optical aberration distorts stars at the edges of your field of view, making them appear elongated or comet-like rather than as pinpoint dots of light.
Until now, the only solution to this problem was expensive and bulky coma correctors. But we are excited to introduce a revolutionary innovation that will change how you see the universe forever — the brand-new Houdini Coma-Correcting Eyepieces.
Three months after their release, these eyepieces have received rave reviews. Read what observers are saying about them!

The image below graphically illustrates what the Houdini coma correction does in a fast f/4 Newtonian telescope. The spot diagrams are greatly magnified to show the optical aberrations more clearly. Near the edge of the field, star images are 5 times smaller in the Houdini 20 than in a standard 20 mm eyepiece!
Houdini eyepieces have been perfected to provide telescope users with the best image quality and ergonomic features:
- Well-corrected ultra-wide 86° field with sharp star images across the field even with fast f/3 Newtonian optics
- Comfortable 20 mm eye relief with folding rubber eyecup
- Multi-coated optics combined with high transmission glass types and blackened lens edges for superb contrast
- Flat field requiring less than 0.7 diopters of accommodation across the entire field
- Low distortion providing constant magnification across the field
- Convenient size and weight with comfortable rubber grips
- Filter-threaded barrel with non-slip safety kerfs that will not get stuck in the focuser
- Eyepiece cap with glow-in-the-dark focal length

“Houdini eyepieces combine optical excellence with great ergonomics. It's a premium solution for all Newtonian telescopes, now available at an affordable price.”
[Robert Houdart, creator of the Houdini Coma-Correcting Eyepieces]
Why Coma-Correcting Eyepieces?
The Houdini eyepieces usher in a new era of observing with Newtonian telescopes. With parabolic coma correction built into the eyepiece, there is no need for an expensive and cumbersome coma corrector. The bulk and weight, cost, mechanical flexure, barlow effect, and focus in-travel of the coma corrector are removed.
You will never again have to worry about eyepiece positioning in a corrector. Just place the eyepiece in the focuser and focus to completely remove the coma from the parabolic mirror. No need to fumble with the tunable top or locking screws of the coma corrector when switching eyepieces.
The Houdini 86° series will further be expanded with coma-correcting eyepieces from 30 mm down to 4 mm focal length with the same optical excellence and great ergonomics. The goal is to completely eliminate the cost, bulk, and hassle of coma correctors for visual observations.

Houdini 12 shipping in second week of August
The first batch of Houdini 12 will be shipped from KUO this week. We will validate and package them in our EU offices, and begin shipping them around August 12.
Houdini 12 available in July
The Houdini 12 prototypes we received a few weeks ago have been successfully validated. It's a beautiful eyepiece that packs a lot of goodies into a compact body.
Quality Assurance of Houdini eyepieces
To ensure the best user experience, we validate each Houdini eyepiece in a 200 mm (8 inch) f/4 Newtonian telescope.
Clean your Houdini eyepieces with ROR
We've been using ROR fluid for many years - it's the best solution we know for cleaning eyepieces.
Houdini 12 mm 86° design and validation
The optical and eyepiece housing design for the Houdini 12 mm 86° coma-correcting eyepiece has been completed.
“It is impressive to see how well the Houdini 20 removes the parabolic coma at f/3.6 and produces a very sharp, ultra-wide field. Also at f/5 you get an almost perfect 86° field with stars sharp to the edge, easy to observe because of the comfortable eye relief.
For my observing with the big telescopes the Houdini 20 has replaced the cumbersome 100° eyepiece in a coma corrector. It is a much lighter and handier solution.”
[Robert Houdart, creator of the Houdini Coma-Correcting Eyepieces]
