Tight screw

[davidlf]

Hi...just taken delivery of my new Sktwatcher 200P ...what a beauty.. !! However, I need to collimate it but when I try to loosen the philips screw on the secondary mirror so i can make adjustments, it just wont budge. I dont want to end up distorting the spider vanes , any ideas of how to loosen it would be of great help, it really is very tight...!!

Thanks in advance for any suggestions

My 150p was the same, I loosened the 3 allen screws first and then carefully held the secondary mirror holder whilst adjusting the philips screw.

This might be of interest, the 150p had this problem.
