Dew falls onto a surface. So long as your shroud is covering the upper openings what is exposed on the underside does not matter too much. Once you have the tubes extended in place then maybe attach with tape ( small bit just to see if it works) or even Velcro tabs between the upper assembly that holds the eyepiece and the lower assembly that holds the main mirror. Make it tight enough so the material does not sag into the light path. The small secondary mirror opposite the eyepiece is generally protected from dew by the upper assembly tube.
soon be time to get yourself a moon atlas so you can name what you see and know how wide and deep different craters are or how tall the mountains in the middle are.
Good luck. Clear Skies
not sure if this will work but here goes
