Never argue with a fool.Onlookers often can't tell the difference.
Quote:i wish you would fuzz the locations on the map a little bit... bit of a privacy concern.
Quote:However, despite the agreement at ~SQM 19, there is no longer agreement above SQM 21, and, what is worse, the DSM gives non repeatable readings.
First and foremost observing love: naked eye.
Last but not least, telescopes.
And I sometimes dabble with cameras.
Quote:That is a good advice! I will shut down everything not needed (I think the the "airplane use" switch shuts down every radio link) and test it for repeatability the next time I go to a dark site.
Quote:One feature that would be very useful wold be the possibility to query all reading in a location (all within a give radius) and plot them against time.[...]As for the SQM if it were possible to close the camera diaphragm and shot (ie to take a dark automatically) then it would also be possible to take 5 darks and 5 readings in a row, and by averaging to get a much better estimate.[...]So far it seems that if I take 5 readings and average them, and correct for the bias i can get a good estimate of the sky.
