Baader Planaterium Hyperion 13mm Eyepiece
Voice your opinion about this subject in our forums
These are large eyepieces. The 13mm weights about 13 ounces. As a visual eyepiece, I have found the Hyperion's deliver superb sharpness and color fidelity across their 68° wide, flat-field, even in faster telescopes. In my comparisons to the Orion Plossls the Hyperion excelled in every regard. 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 eyelens, and an optical design that is free of annoying 'kidney-beaning' and blackouts. This has become my favorite lens for most viewing and the wide field of view allows me to use it where I would ordinarily have to use the 25 mm Plossl to get adequate coverage.
The eyepieces are not very expensive either- right now they are going for $119 in most focal lengths.
The only downside that I have found is that the weight means the scope will sometimes settle a little since it is not balanced as well. I solved this by tightening the springs on the XT8 slightly.
