Hi ausastronomer,

I think I may need to ask the shop where I bought the scope how to correctly collimate my scope.
I'm worried I may do something wrong adjusting the secondary mirror.
I'm a little unsure what you mean by moving the secondary so its 3mm to 6mm closer to the primary. Do you mean so in the image the reflection of the focuser and collimator eyepiece look centered?
By holding the secondary spider pane and twisting slightly clockwise and looking through the collimator pinhole, I can see that the reflection of collimator moves up, more centered in the sec. mirror reflection.
