Mine was only a 114 mm. I used to collimate using a film canister with a hole drilled through the lid. I don't see why you couldn't use a Cheshire/sight tube. Presumably a laser wouldn't work. I didn't have one of these until recently.

I was able remove mine and find focus. The spherical abberations were intollerable though
