Sky-Quality Meter (SQM-L)

I was shocked how easily it picked up the subtle glow from a nearby town that I never noticed before. The readings in magnitudes per square arcsecond make light pollution comparisons so simple. Definitely a must-have for anyone serious about dark sky hunting.

Took this out to a Bortle 3 site and the readings were spot on, down to the tenth of a magnitude. The sensitivity is impressive for something that fits in my palm.

Finally got to test it under a truly dark sky and the readings are incredibly consistent, even picking up subtle differences between moonlit and moonless nights. The sensitivity is way better than my old phone app.
