Hello, I just bought a used Skywatcher 200p. I just tried to collimate it but without much success. The collimation screws don't have springs but instead it has rubber washers in where the springs are on my 150p. Is this normal or a previous owner's bodge? Also the locking screws are missing so I need the right size etc to try to find replacements?

Thanks

Are you sure there isn't a screw in that hole next to the Philips screw? It will be a socket head grub screw and black. I think I can see it, but not certain. You will need a hex (Allen) key to turn it. IIRC they are M6.

Hello, there were little screws right where you said . .  thanks

The 200P has lock bolts (the Allen keys) and tilt is adjusted by the silver coloured Phillips screws. There are always springs and once the lock bolts are tightened the main mirror does not shift in my experience.
