Easy , my beautiful ( now sold) Takahashi Mewlon 210 , but once it was on ,,, man you knew it was ON !! awesome views and it stayed on for as long as I had it and that's for over 12 months of transporting on the back of my Ute , so touchy , but worth it in the end .

Stick with it as the finished views are worth it .

So after looking at a star and deciding which direction needs adjusting, I have to take the tube off the mount, hold it between my legs, unscrew the grub screw on the focusing knob and remove the knob, remove four screws from the back cover, and take the back cover off, adjust the collimation screws, reassemble the whole unit, put it back on the mount, and then go back outside and find a star (which is difficult, as the finder is longer aligned with the telescope) and see which direction the next adjustment to collimation has to be, and then repeat the whole process again.

Has anybody come across a telescope with a collimation process worse than this?
