Hi Ken, I haven't logged the readings, but I give them in my infrequent reports on the AZ Observing reports. They are mostly for Norte. I don't post that much, so if you do a quick search on the listserve (if that is possible) you can pick them off PDQ. I reported one for Griffren Ranch following my run there last May (?). I have the L version of the SQM.

My meter is one of the original designs, not the L , LE, or LU. If anyone else has kept a log of the readings could I by chance have a copy of them. I am trying to work out a correlation with the Bortle scale and the emag/per sq arc sec. I have come across a different scale that relates the SQM readings to NELM and the Bortle ratings, but I need more readings from others to add to the project. All I need are the readings and the date and time for now. Any help would be appreciated.
