Muddy, maks cannot be collimated by the user. It needs to go back to the dealer for repair.
Bird, I have been saying this for nearly a year. I think that I was considered obsessed with collimation. This is one good thing about owning an SCT. Collimation is slightly easier than other scope designs; although much more critical. Barlowed collimation is necessary for ultra tight collimation. Everytime I move my scope it gets a collimation check. Usually, it has moved just a little, enough for my eyes to see it, but not enough for the untrained observer. I also keep records with the toucam with images of out of focus stars. It helps to review your collimation techniques.
Incidently, I would like to stress that collimation should only be performed on a cooled scope. If you collimate before this you will get incorrect difraction rings. Also moving the scope from one side of the meridian to the other will affect collimation. Not a lot, but some movement will be detected. Collimation should be undertaken after a meridian flip also.
Good topic Anthony.
