Hello Marc. No, the baffle must be in their place. If not, the light of the sky will enter directly to the camera or eyepiece. If you see the new barrel images, you see the original aluminium trefoil between the two new trefoils. The first one is fixed to the original (in this way, the telescope can be focused with their knob) and the second one is floating with spring and screws as a normar Newton barrel; and the rear cover now have three holes to access to the colimation screws. The central hole in the second trafoil have just a slight play with the baffle, and a small collar fit the mirror centered. The mirror is glued to this second trefoil with silicone. Is difficult to write for explain it... will be easier with a pen in my hand (and a bier in the table
)
