Vixen Optics NPL Plossl 40mm Eyepiece (1.25") (preowned)

Sharp, light and simple, the 2-group/4-element Vixen 40mm NPL Plössl Eyepiece design offers flat, clear imagery well corrected for chromatic aberrations.  This is a great lunar/planetary viewer which-with its extremely low magnification, minimalist opticals, and profoundly long eye relief-makes a great digiscoping ocular with your camera's lens zoomed up a bit.
