collimation free dob?

Hi All,

Something to ponder about and whether its doable. If you think I'm mad, I apologise now.

Do you think its possible/feasible to design a DOB such that it never requires to be collimated. I understand that from time to time the primary may need a clean, but can it be replaced back into its cell such that its aligned.
Or are there too many variables for it to be doable (like the glass cooling/expanding).

Better still what about a self collimating dob ? (I dont mean collimating it yourSELF either).

Something to think about !!!
