Just got a great deal on some 19mm plate glass.
I've bought a circle cutter off evilbay and will pick up some cheap 3 or 6mm to practice on.
The plate is 550 by 1100 so I can go crazy but while I'm waiting for the cutter to arrive, I thought I would ask for opinions on what size and f ratio you all think I should go for.
I made 2 dobs about 15 years ago but pretty mild at 6inch/f8 and 8 inch/f6 so I would probably like to go a bit bigger this time around.
I originally thought of 12inch/f6 but I've seen some 16 inchers and think an f4 might be do-able.
My old ones were ok but I'm 15 years older and a bit more patient these days so I think I might be able to give a 16 inch some justice.
I'm in a suburban back yard in Tannum Sands with a street light right out front so not the best but I was looking at a truss dob setup.
Anyway, pretty excited about this years project so let me know what you think.
