DDO. WOW.We sold out and filled every seat available for Makers at the David Dunlap Observatory: Old Tech Meets New Tech. Arriving visitors who had never seen the site were slack-jawed at the beautiful telescope and administration building.The David Dunlap Observatory, sitting right smack in the middle or Richmond Hill, is Canada’s largest optical telescope. It’s operated by an all-volunteer force of members of the Royal Astronomical Society of Canada (RASC) Toronto Centre.Who knew that the RASC-TC members are uber-makers? The session featured presentations and equipment demos by Jim Chung, author of Astro Imaging Projects for Amateur Astronomers , and Lance Clarke and Allard Schipper of the Southern Ontario Telescope Makers Group. We were astounded at the variety and complexity of amateur-built telescopes. We heard how Allard built much of his equipment using facilities and tools from the Toronto Tool Library. The Markham, Richmond Hill and Vaughan libraries may be hearing from us.We had the special privilege of seeing and hearing how the volunteers maintain the main telescope. Who knew that mirror resurfacing by aluminum vapor deposition in a vacuum chamber could be done on site? Who knew what the preceding sentence meant before their patient explanations? Where else do you get to see huge 110V DC (not AC!) systems?Along with the telescopes, YLab makers Jack, Jay and Richard brought out a 3D printer, robots, light sabers and other creations. Richard drew up a 3D model of the DDO dome and had it printed out by the end of the evening.We’d like to thank:
- The RASC-TC’s Diane, Karen, Paul, Nicole, Gilles, Eric (those are the names we remember) and other members who so generously took the time to show us this gem of a facility and explain its workings.
- The DDO’s volunteer high-school students for helping the RASC-TC members
- YLab’s high school volunteers Katrina and Maxine for handling welcome and registration duties.
- Pek and Uncle D for taking the awesome photos you see above and on our Facebook page
