Title: Very difficult to align set screws
Review: This might be a great item for the very well experienced, but the item is very difficult to recenter if you move any of the set screws the smallest amount. I inadvertently tightened a thumb screw when I replaced the batteries. I have never been able to accurately realign the center target, and $90 is going in the trash. I cannot see any reason to have such a wide range of adjustments possible on an eyepiece used to center for initial alignment to begin with. Additionally, there was so much lubricant on the recitile frame, a tiny amount smeared when moving the adjustment screws. There is now a distortion when illuminated. I am switching to an Orion with a fixed rectile.
Is the review positive or negative?
