I am in the US where it's summer, and most of the restrictions are lifted. Luckily the outdoors are especially low risk for covid spread so the mountains are the best place to be. With most photography I'd say gear is less of a factor than a good eye and knowing how to read a light meter. Unfortunately astrophotography requires some fast lenses and high ISO capabilities, so that advice would only go so far... Best of luck, stay safe out (or in) there!
