Out of Focus

Problem:

This image is so much out of focus that the stellar images appear as "doughnuts".

Fix:

Change focus setting by a comparatively large number of units in either direction in order to try to get stars to appear as "filled out circles" (may have to iterate several times). Then, do a focus sequence for the finer tuning.
