My sextant has developed an annoying flare artifact.  It appeared the other
day when I was doing sun sextant shots on a very bright summer forenoon.  I
was using a split mirror and the 6x telescope (Astra IIIb)  The flare
appeared around the right half of the sun when the sun's image was in the
left side of the field of view, but vanished leaving a clean image of the
sun if I moved the sextant so the image was over the black half of the field
of view on the right.

I cleaned all the shades, the horizon glass, and both external surfaces of
the telescope's lenses (ie front and back), but no imrovement.

Any suggestions?  Sounds to me like I might have a problem inside the
telescope.
