1.The SV190 Ultra Flat Field telescope eyepieces. With a generous 65° apparent field of view, these eyepieces provide more field of view than typical Plossl eyepieces, all the while providing a fantastic image from the center to the edge.
2.The thread under the eyecup is convenient to match the camera for photography. The eyepiece can match SV406p for scenery, too.
