That definition of astronomical twilight - 18 degrees below the horizon is discouraging for sure and even nautical twilight as 12 degrees is to a degree. But with such an event as this, you just have to try and make the best of the situation on the day. As has been suggested, it might be worth doing some images a few days before - the separation is not a5 its minimum but seeing should be better. I’m going to try.
