Hi I am in the process of building a light box for and ED127, and the guy says that the size of the Dew Shield is 157mm O/D. I must admit I am not sure on this and cannot seem to find the actual specs on this scope. Just wondering if anyone has one of these who may confirm the size of the Dew shield. No big deal making the cut a little large, but it is a nightmare if it is too small to fit over the dew shield. Any help appreciated.
