I did use the new 'EditCP' tool in hugin-2015.0.0, which made finding
and removing the worst of the CPs an easy task.
How did you do this? Each image on the preview is tiny (since I have 30

The convergence behaviour of the mosaic model is really quite poor.
I have recently completed shooting a very careful trial, using
a cantilevered tripod (Benbo) over a map on my dining table.
