WARNING: It was recently brought to my attention that superglue (cyanoacrylate) CAN damage your glass and camera sensor. I haven't figured out a surefire way to make it work without the superglue, but I also didn't have any problem using a tiny drop. For safety reasons, try the method of just loosening and tightening the screw to find the ideal position. If you MUST use superglue (like I did in one of my lenses), make sure your glass is completely clean and keep the lens in a well ventilated area until fully dry. Also be aware that using superglue will make your scope unserviceable. Other pros can't open it and make it better, so I advise against using glue!
