I set up the scope when I expect a run of clear nights. If the chance of rain is basically zero I leave the scope set up; OTA, eyepieces and all. I put the caps on the scopes and eyepieces and leave the dew strips running (I use a 240V to 12V power supply). If there is a chance of a small amount of rain but then clearing for the next night I take the OTA inside and use a BBQ cover and plastic bags on the mount. If I won't be able to observe for a few days I take in the whole rig. I'd like to get the setup a bit more permanent but it's scarcely an issue atm: I've had one clear night since Sept.
