Thanks to Stephen I have started working on a 365mm F3.something mirror.
Last nights rough grinding brought it below f4. With a 6mm sagitta.
I'm completely new to all of this. We got our first telescope a month and a half ago. A Nova 4inch reflector. Which I have now made a table top mount for.
To me I enjoy the challenge of being able to make something so perfect as a parabolic mirror only using the most basic of tools and tests.
Once I get to the end of fine grinding I plan to build the scope, or at least most of it so that I can test the mirror during polishing.
The glass isn't perfect, the back has two large chunks out of it, so no idea what the end quality will be. But it's all part of the learning process. Next piece of glass is also on its way from Stephen.
