Perhaps those who are experienced in the technical aspects of optics can answer this question.
I have a BTX unit which has developed what appears to be an issue with collimation. If I look at the top of the image, there is an overlap between what can be seen in the left image and when can be seen in the right image. I have posted two cropped images below to show this. You can see that the leaves in the left eyepiece are cut off compared to the right. The overlap is quite noticeable and if I look at it I start to get a bit of eye strain.
The unit has been back to Swarovski twice (!) and I have been told that there is nothing wrong with it. But there is, isn't there?
