GAA have a 17.8 inch Truss tube dob we have had for a few years.
We need to improve the mount for the mirror cell to make it more robust.
Can anyone make a recomendation for a mirror cell that will accommadate this size mirror.
It is currently sitting on a pivot pin and see-saw arrangement of 3 individual cells (very fragile)
We need a robust mirror cell to mount the mirror on.
Any suggestions where we can get one ?
