180mm 9 points cell

Hi guys
This is a 9 points cell that I design to use in my ATM newtonian telescope.
for this cell you don't need to use any spiral spring to colimate the mirror,
this system use a central support and 3 bolts to adjust the mirror.
be carefull cause if you turn the screw moreover, you can brake the mirror cell or the base.
As you can see on the pics, this cell is already in use in my 180mm newtonian telescope and unless for me, I got a great results for now, I'll make some upgrades on the fu
