I have a 4" Meade DS-2102Mak OTA that is out of collimation. I spent hours last night trying to collimate it, but have still not finished because the process is so painfully longwinded.

Normally, most telescopes have three screws or three sets of two screws for collimation, and they are directly accessible. But on this telescope, they are behind the combined back cover and mounting block, which has to be removed for every adjustment of the collimation screws.

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 either no longer aligned with the telescope (or I've nudged it)) 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?
