Tele Vue Astigmatism Corrector - 2.25 dpt
Many people have a slight astigmatism (curvature of the cornea). During the day, when the pupil of the human eye is very small, this is not noticeable. Very few people need glasses for this reason.
During the night, however, the pupil is wide open. This makes the astigmatism more noticeable. The stars are not nicely point-shaped, but distorted. This reduces the aesthetic pleasure of observation and effectively also the achievable limiting magnitude.
Advantages over correction with glasses
- better coating and thus better light transmission
- more comfortable viewing - you have the same viewing behaviour as without glasses
- very precise adaptation
Adaption of the Tele Vue Dioptrx to eyepieces
