Selenographische Koordinaten: II. Abhandlung (Classic Reprint) Buchkatalog

Excerpt from Selenographische Koordinaten: II. AbhandlungDie beiden Kreise lassen sich mit je zwei Mikroskopen mikro metrisch ablesen. Diese für das bloße Aufsuchen unnötig scharfe Ablesungsart wurde gewählt, weil es für sichere Identifizierung mitunter wünschenswert ist, eine innerhalb weniger Bogensekunden verbürgte Position rasch aus den Ablesungen der Kreise herleiten zu können.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
