Quote:With the wide field of view, how do you account for the brightness of the Milky Way (or lack of same) in the field?
Quote:I don't even care all that much if it is calibrated for it. I just want an objective measure
Quote:an un-calibrated reading gets you subjective reading - if using the same device, then you can get a subjective night-to-night difference in reading

Quote:I think there is some confusion going on here between accuracy, precision, and objectivity.
Quote:Last night's numbers were above my SQM readings for the first time. Usually the app's numbers were lower. If we can find the happy medium, we are in business.
Quote:"Scientific objectivity means that independent observers, using the same procedures, will come to consensus regarding the phenomenon they are studying. In other words, personal opinions, values, and biases will not change observations recorded with scientific objectivity."

Quote:A little heads up. This is a screenshot of the free Public Outreach 'lite' version aimed at a broad audience with the goal to provide tons of measurements worldwide.. It uses an approximate scale, no output in SQM/NELM and lacks the maps and weather features of the pro version. But this version will submit detailed measurements to researchers and the folks at the IDA.
