First, bring the telescope indoors and allow it to acclimate to room temperature. This will allow moisture to evaporate. Once adapted back to room temperature, put on all caps and store out of direct sunlight. Do not display your telescope indoors without the caps.
You can remove the Optical Tube Assembly (OTA) from the mount, and store it vertically or horizontally, although vertically for reflectors with the primary side down (bottom side down) is the preferred method.
