[middy]

Was out doing some more testing of the scotch mount last night. On the last image I took one of the stars seems to have blue smears around it. None of the other stars seem to be affected. Is that star overexposed? Does anyone know what causes this?

The first image shows the overall shot. The star in question is near the right edge of the picture and seems to be alpha Carina.

The second image is a crop around the star from the full size image.
