    Hi Martin, A 10 second exposure should normally be sufficient for a repeatable inspection result but light pollution and very oval stars does not help. A star rich area will also help. An other thing you could do is first bin 2x2 the image. See tools, bin or stretch. This will improve the star detection and then apply F4 for inspection You could hit the F6 button to display the center and corners in one image for visual inspection. cs, Han

    In principle the comet flux in the star-only image should be removed by sigma-clip stacking since it is drifting. Does this work for you and does the comet head still look good after stacking and missing flux?
