I did it this evening, because I couldn't wait until tomorrow. When I unscrewed the focus lens, I could see what was happening inside in its entirety. Truly, the three screw system is absolutely unergonomic I suppose. Anyway I solved the problem. Many thanks, Mike, and thank you also Seelive, for your kind comments.

Mike, that seems to be the only solution at this point. I will try it under daylight tomorrow. You seem to have gone through the same problem. I will report the result tomorrow.

Hi Seelive, I meant that when I rotated the RA axis, the image moved away from the previously focused centre, a symptom that I need recalibration. Yes, perhaps I overscrewed them and something went wrong.

I am a newbie who now struggles with calibrating the polarscope of my newly bought SW AZ-EQ6 Pro mount. Following some Youtube advices, I centred a distant object on the reticle, and found some gap between the object and the centre when I turned around the shaft 180 degrees. I tried to calibrate it by turning the three screws as advised. But the object image would move father and farther away from the centre. Judging from that right turn screwing has reached the limit on all three screws and left-turn screwing is the only option left but leading to the increasing gap, am I right in thinking that the reticle has dropped inside? I remember that I had turned around the screws mistakenly for trying to solve another problem a few day ago. If I have to take out the whole polarscope to reset the reticle inside, will it be technically too demanding for people like me who has useless fingers? Your advice will be greatly appreciated.
