Description

n. Spelunking: the exploration of caves, especially as a hobby

This is a two panel mosaic that I shot from June through October 2019. I also shot Near IR and SII data that I didn't end up using. Maybe some other time.

Narrowband was shot in Somerville, MA (SQM reading at zenith = 18.0 mpsas). Broadband was shot at the ATMOB Clubhouse in Westford, MA. (SQM reading at zenith = 20.17 mpsas)
