lost sticktion

The integrated dew shield on the Questar has lost its sticktion. It slowly slides down the tube, especially if vertical. So I threw an elastic band around the shield. When needed, the rubber band can be rolled off the shield onto the tube.

The tolerances of the Questar are so tight though that the band cannot be left on the bottom end of the shield. So, for storage, I flipped the dew shield tube.
