Quote:I have the original SQM, and very often wish it had a smaller characteristic field than its 80 degrees. Given the variation in sky brightness, even at dark sites, and particularly when the milky way is well up, makes a smaller sampling field very useful.

Quote:Thanks everyone. I pretty much had in my mind I was getting the SQM-L but before I pulled the trigger I wanted to see if anyone knew something I wasn't thinking about. SQM-L it is. I realize this is far from a must have. It's more of a toy for me than anything but it will be nice to have numbers to put with my subjective assessment of the sky quality.

Quote:It would be very helpful to other amateur astronomers if more people had these AND posted their readings to dark sky sites to characterize them. You could even document the light domes that are present.

Quote:One man's "Mag.6.2 sky" is another man's "Mag.6.7 sky".But one man's "Mag.21.40 sky by SQM" is another man's "Mag.21.40 sky".Objective reality is a far better indicator to another of the sky conditions at your site than are subjective evaluations.
