Baader Hyperion Aspheric 31mm Eyepiece




About Baader Hyperion Eyepieces.

Aspheric 31mm Hyperion eyepiece by Baader, high quality with perfect field definition.

Simple Erfle designs, offered for low money under different names, have significantly less off-axis performance. Light rays near the field stop are refracted stronger than rays near the principal axis. This results unsharp pictures near the rim, especially with uncorrected systems.

The aspherical correction corrects for these abberations. Image definition remains very good across the entire field and distortions are reduced to a minimum. And what is more, the eyepiece can be kept more compact and lightweight.

The Aspheric 31mm's most important features:

  • Excellent viewing performance without kidney beaning
  • Extremely small and lightweight
  • Very suitable as photographic plane-projective with all connecting options of the Hyperion system
  • Optimized Phanto Multi Coatings for maxium transmission and good contrast
Technical Features:

  • Optical configuration: 8 elements / 5 groups
  • 1¼" AND 2" barrel, both with self locking safety groove
  • 72° Apparent Field of View
  • 1.25" and 2" Telescope Adaptation
  • 31mm focal length
  • By unscrewing the 1¼" barrel (which contains the first group of lenses), variable focal lengths may be achieved by adding our Finetuning Rings.
  • A M48 thread is located between the 1¼" and 2" barrel, to be able to insert a 2" filter
  • All eyepieces are suitable for afocal and classical eyepiece projection
  • Weight: 390gr.
