Barton Lake Instruments

Software and instruments for quiet precision — steady, dependable, and made to hold up under real conditions.

Software

Measures your sky's seeing every minute, all night, with a small camera pointed at Polaris.

Records, charts and publishes your sky's darkness every night from a Unihedron SQM-LE or SQM-LU.

Barton Lake Instruments designs and builds measurement equipment meant to work quietly and correctly, day after day, wherever it's put to use.

We're just getting started — more about our instruments and how they're built is coming soon.
