Thank you for the very direct message; apparently for whatever reason we
have hit a nerve and if so, I very much apologize.
The magnitudes comes directly from the GSC catalog (fainter stars) and the
Tycho Catalog.
For the record, most amateur telescopes (which this field test was designed
to assist, not antagonize!) will not reach magnitude 20 visually - that is
the key, here VISUAL - so what is the point of including stars to that
magnitude?
Thank you for your warm and kind words.
Clay
