 Antares Speers-Waler Series II Eyepieces These Speers-Waler eyepieces offer a massive 82-degree apparent field of view and excellent eye-relief for comfortable wide-angle views of the sky. All have 1.25" barrels so can be used with any modern telescope. Pin-sharp images and high contrast make these a delight to use. The wider field of view allows you to use a higher magnification and still fit your object into the field. Often, this improves contrast against the background sky, especially when viewing star fields and clusters. The 5mm to 8mm zoom enables you to match your magnification to the object and sky conditions for the optimum view. |
