I took first light from an observatory that I had built at a remote get-away, and which by certain providences I was able to equip with first-rate gear. I could now capture the deepest of deep- sky treasures. As I recounted in the first part of this story (which appeared in the March/ April 2011 edition of nova), the dream had its first stirrings in my case at summer camp, when I was about 12 years old. I owe so much to a camp counsellor, whose name I can no longer remember, who introduced the glory of the night sky to a group of us, the nerdiest kids in the camp. I became obsessed with observing, especially deep-sky objects. I endlessly poured over reference books and star charts to prepare target lists, and to come up with strategies for how I might find those celestial treasurers from the sidewalk in front of my parents’ home, under the heavily light-polluted skies of urban Montreal. I learned by doing, saving money from paper routes to buy two telescopes (with help from my parents). And all the while I dreamt about building my own observatory, equipped with “serious gear,” and located infinitely far from city lights; a place to which I would escape to plumb the deepest of skies. Aſter high school, “recreational” astronomy all but disappeared from my life. When I would occasionally think back to the time when I had been consumed by the pursuit of the next deep- sky wonder, I was puzzled at how that dream, once so present, now seemed so removed. But it must have been there all along, just under the surface, waiting for the right time and trigger to return to the fore. And when it did, I had a family, and that dream would change everything for all of us. e trigger came in the spring continued on page 2 First light images with a CCD camera
