Hey bird - yeah been messing around with the barlow and laser and think I have gotten a good result (easier using the paper over the end of the barlow as opposed to the view in the laser return screen).
Problem is that if I use the laser to do the secondary (center the beam in the primary centre ring) then this can be off (not by much) depending on how the laser is seated in the focuser.
Oh well it all looks ok visually as far as collimation allignment but I do have an issue with star tests but will ask in its own thread
