I have a Like New Nikon ED 50 with the much desirable MCII 13-40 eyepiece I bought it to try it out and compare to my other spotters and found that it has the edge on my friends 50mm Vortex but now I am releasing it. It has just been set on a tripod on the porch and it has no markings and is in mint condition comes with everything it came with in box. This is the best 50mm compact spotter you can buy. With the now extinct 13-40 eyepiece. I purchased the MCII eyepiece alone for 400 and good luck finding another one. I am asking 525$ for both the spotter and eyepiece.
