Thanks again. The GSO is a good focuser but overall I have some doubts. At this stage I am not sure the existing focuser is the source of the problem and if it is, there is no guarantee the GSO is better than the CYCK noting that the GSO gets some mixed reviews online including a less than glowing dedicated tilt test by Narrowband Channel. On top of that it would need new focuser brackets and mods to the tube and I would be giving up a rotator and tilt adjustment.
I will need to give it more thought if I am unhappy with performance of the existing rig after a full test.
