The subject of this symposium is the fine structure of the solar chromosphere. Progress in this field of reserach will depend to a high degree of the quality of seeing, resp. on the effective angular resolution available on the ground. Today's situation of solar ground seeing has changed distinctly in the last years. I would like to report here a few new aspects, which could be condensed into 3 questions:

  1. (1) Are there on the ground ‘good seeing windows’, comparable in quality with stratosphere results obtained from balloon borne equipment?

  2. (2) Is there a chance to resolve from the ground the solar scale height, corresponding to about 0.1″.

  3. (3) Is there a residual fundamental atmospheric seeing noise resp. a basic limit to the atmospheric Modulation Transfer Function (MTF)?
