Hello,
I am trying to figure out an easy/economical way to collimate the primary mirror in Skywatcher 130PS (Az-GTi).
Unfortunately there are no 3 screws to collimate the primary mirror as it is fixed in position on the back plate disc which screws on to the tube.
Unfortunately the telescope is not 100% collimated. I have used a laser pointer to adjust the secondary, but the star images are not sharp.
I have tried to search for a reasonably priced collimatable primary bracket for that size but so far unsuccessfully.
Has anyone found a hack to do it (eg 3d printing) or primary mirror holder that can be fitted on the telescope tube? I do not mind a bit of DIY.
