Harold Kettleworth

Retired optician who hand-ground his first mirror in 1978 and has never let anyone forget it. Harold covers visual observing, Dobsonian culture, and the spiritual decline of astronomy since people started 'letting computers do the looking.' His columns read like a man shaking his fist at a GoTo mount.
