So my scope loses collimation when I engage the mirror locks. I’m going to put a Crayford on the back and lock it down then collimate that way see if it works. At this stage I’ve followed the process but stars appear like they have a small comet tail after collimation is done and I try to lock the mirror. Any one no any trick I don’t with collimation or am I supposed to chase it all night long. I forgot to mention that I’ve also found that the course focuser is adding to the issue with the mirror flopping around a fair bit when trying to re focus the star. Could the focus mechanism be the issue here and if so how do you tighten the tolerances? Is it a know issue for the course focuser to put misalignment into C14s after collimation is done and refocusing the star? I’m scratching my head here not knowing what can be causing it?? Mirror locks or focuser?
