Protecting kit overnight

[Swoop1]

I have a Telegizmo 365 cover for my pier and mount but it isn’t big enough to cover my scope as well.

I plan to be up in the morning for the occultation of Mars but would like to set up before bed.

Do you think covering the scope and mount with an old vinyl shower curtain will do?

 I am quite confident re garden security, it is just weather conditions that concern me.

I leave all my kit outside all night when imaging so I can't see this being a problem. I do use the 'Rain Alarm' app and I also have a rain sensor, but if the forecast is good, I don't see everything out overnight being a problem. FWIW I actually converted a cheap BBQ cover to a lightweight scope cover, which works quite well. Just taped up the seams.
