First look at the SKY Quality Meter.

Hello Dark Sky fans,

I am up at our site on Mt Graham where over the last few years
we obtain V band sky measurements between 21.7 and 21.9 Mag/sq arc second using CCD photometry. (no moon)

I just measured the sky with the Unihedron Sky Quality Meter and
obtain 21.8Mag.

In Tucson I measure around 18.5 with the sky meter I have been working on and the SQM agrees as well.

Its a handy dandy accessory and a must have I.M.H.O.

Have a nice night

Dan
