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 has worked hard to give the Hyperions the world’s finest optical coatings, superb mechanics, and their unique multi-functional design.
High grade water-white glasses are used throughout, to deliver a crystal clear view with low scatter and excellent colour 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 multi-coatings 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 eyepiece 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.
