1. This superb ultra wide angle eyepiece has 80 degree field of view, great comfortable for view directly of the deep space objects. Standard female thread to fit a 2 inch filter. the 7 Elements in 5 groups Design bring the great crystal clear images. 20mm focal length eyepiece give you lower magnification, would be good feeling when doing observation. 

2. Note: This eyepiece is actually a dual eyepiece. If you unscrew and remove the lowest element, it becomes a 30mm eyepiece
