Yes the bit sticking out is threaded. It looks like it is part of the mirror cell. I am uncertain how the baffle will be connected. The rear is threaded on the outside (the shiny bit). It will not be independent. Rear collimation is done via the collimation bolts 60 degrees from the fans but further out. Rear collimation is rarely used, but necessary for RC's. Front collimation is the same as any cassegrain.
