Exfso, it is not a problem with your Tak, it is caused by different refraction angles of red and blue light through the atmosphere and depends upon the height of the object above the horizon.

It can be fixed by placing a wedge shaped prism in the light path, there is a variable commercial unit available for this (see July S&T for details).
