We are a Canadian based Amateur Telescope Making supply shop. We are located in the greater Toronto area but are focused on supplying all of Canada (and beyond) with materials and parts that people need and use for making their own astronomical telescopes. And of course that means all aspects of ATM from grinding your own mirrors from blank material, to assembling using off the shelf optics, to testing optics, and everything in between.

Oh, and we are ATM’ers ourselves too! Be sure to check out our projects and builds.

Gordon Acorn
ATM Chief / Founder

Gord has been an ATM’er since his pre-teens. He has lots of goals and projects he still wants to attempt and hopes to get to show them off right here at ATMOS. He’s also an avid backyard astronomer with an interest in planetary, lunar, and double-star observing.
