"The four points of the compass be logic, knowledge, wisdom, and the unknown. Some do bow in that final direction. Others advance upon it. To bow before the one is to lose sight of the three."
Quote:Probably not the originator in at least some cases, but Becvar's Atlas of the Heavens (~1962?) is the earliest I recall which seems to have set the standard adopted by Tirion.
Quote:Norton redrew his charts yet again for the 9th edition published in 1943, extending the magnitude limit of the stars from 6.2 to 6.35. Positions were now given for the standard epoch of 1950, as against 1920 previously. The 9th edition charts remained in use up to and including the 17th edition of Norton’s Star Atlas published in 1978

Quote:Lee,A clue might derive from the first atlas to use the circle with interior cross to represent a globular cluster. This is most definitely a modern symbol, and I do think Becvar's was the first atlas to use it. And how about double circle for planetaries; again a Becvar first? The ellipse for galaxies might predate Becvar, though.In the main, I think a sufficient originality is found in Becvar's work to nominate him as the father of the modern star atlas. Tirion has most faithfully carried on that scheme.
