The Baader Hyperion 68° eyepiece starter set includes four standard Hyperion eyepieces (5, 10, 17 & 24mm) and a special protective case.
The Hyperion range of multi-function eyepieces feature a modular design with the ability to change the focal length via extension rings (except for the 24mm model). All Hyperion eyepieces use high quality Phantom group-coatings for maximum contrast and zero internal reflections.
Both 1.25" and 2" barrels are included. Each barrel is threaded for connection of all standard 1.25" and 2" filters.
Various focal lengths are possible with the addition of FTR fine tuning rings (excluding the 24mm version).
Baader Hyperion eyepieces provide a wide 68° apparent field, sharp field stops and excellent ergonomics for comfortable observing. Baader's Phantom Group coating is a 7-layer broadband anti-reflective coating with extremely low residual reflection. Each group of lenses has this coating applied. The coating has been optimized so that they are most effective where the human eye has its greatest sensitivity at night, at around 520nm.
