Dialexis de novae et prius incognitae stellae inusitatae magnitudinis & splendidissimi luminis apparitione, & de eiusdem stellae vero loco constituendo ...

No one, however, will wonder at that disagreement who recalls the common and long-standing complaint of all those more skilled in astronomy regarding the uncorrected description of the starry heaven. For what we have of this today, from Ptolemy and Alfonso, is in need of correction because of many errors that have crept in little by little through the fault of scribes and the length of time. We do not hesitate, therefore, to assume these observed distances of ours to be truer than those which are drawn from calculation, especially since we explored many of them with Dr. Paulus Fabritius, the Emperor’s Mathematician, through frequent iteration of study over several days. In this, I have also been confirmed in my opinion, and as if by the testimony of that most learned man, Hieronymus Munnozius the Spaniard: because I notice that he himself feels the same as I do in his little book published in the Spanish language on this star, and that his own observations agree with mine to the letter. Where, however, we disagree with each other, it will become clear from the following that this happened more by some slip of his than of mine. For it is very easy to slip in observations, unless one has diligently surveyed everything and explored the same thing by observing it more often, as is known to those who have sometimes made the attempt at that matter. It is pleasing, however, here to compare his observations with ours.

Comparison of the author's observations with the observations of Munnozius. Munnozius places the distance of the new star from the twelfth at 5 degrees and 10 minutes; we at 5 degrees and 15 minutes. He places the distance of the new from the second at 7 degrees and 50 minutes; we at 7 degrees and 47 minutes.
