This combination isn't likely to inspire a national chain anytime soon, yet it has the appeal of a toy-filled dream. Tucked inside an inconspicuous lab-like brick building, the wooden, glass-fronted cabinets give this place an Old World flavor that leaps from Galileo to This Old House. In one corner, old planes, chisels, saws, augers and plenty more are carefully displayed; in another are the beautifully cast and finished wood and metal planes in which St. James specializes. Across the store are those magical telescopes, including binoculars, for viewing the far away up close. If you want to talk optics, eyepieces, or the best way to see the next eclipse or that wobbling orb Mars, ask for Warren Kutok, Photon's owner, who's been scouring the heavens for more than 50 years.
