The SWA 20 mm eyepiece is inspired by a series of TMB Eyeglass Eyewear that develops this valued series towards longer-focal length goggles.
The 20mm SWA TMB-Inspired Planetary II eyepiece is designed to achieve maximum contrast, detail and resolution when observing bright objects such as the Moon and planets, both on the optical axis and at the edges of the field of view. This eyepiece is characterized by a high transmission of light and minimal reflections. This allows you to obtain medium magnifications with high quality of object mapping, it is appropriate for any visibility . It combines quality with an astonishingly low price.
For example, in the 8 "f / 10 SCT telescope, this eyepiece allows you to achieve a magnification of 100x with an exit counter equal to 2 mm, being a universal observation tool even in poor atmosphere stability conditions.
Removal of eye relief by 20 mm, the fact that vignetting is practically non-existent, even for those who are forced to constantly use corrective glasses.
