Hi Anthony : )
I did collimate on a star about 3 years ago but wasn't experienced enough to know exactly what to look for . I did centre the donut but the secondary may have been off . I appreciate the link and have taken notice , thank you ! That method will be the next experiment .
I assumed that the Primary mirror was tilting forward when in focusing position but I pulled the corrector plate off to measure the difference and there was no dramatic tilting (maybe half a millimetre) so I really don't know what's going on or which part of the scope to concentrate on .
I pulled off the Moonlight focuser and replaced it with the original Meade back and eyepiece holder in a process of elimination .
I couldn't wait till dark so I tried a light projected through the eyepiece and onto the wall . Not a precise way of doing things but you could see the shadow of the secondary get larger and smaller . I'll now wait till I have time to look at it again . The guiding on the other scope needs more refining .
