The overall finish of the adapter is 1A quality. The compression ring not so much. I can't smoothly insert an 1.25mm eye piece without having to jiggle the lens barrel to get past the edge of the compression ring and get the lens seated fully. Once inserted everything works fine.
A simple, well made part with the features I needed
Need this for those times I am using a 2" diagonal and need a 1-1/4" eyepiece.
Nothing to complicated about this
excellent quality...Could I wish for more...No
Very impressed with design, quality and the cost! This is a great product and with great service by OPT TO BOOT.
