Hi,

Its a bit hard doing things from a photograph without looking at the scope but that looks way out to me.

The first thing you need to do before rotating or adjusting the tilt of anything, is to move the secondary mirror so that it is between 3mm and 6mm closer to the primary mirror. It is sitting too high in the tube relative to the primary and the focuser. After you get this right adjust the secondary rotation and tilt, then get to the primary.

Cheers,
John B
