Get coordinates at specific time

Hi to all , this is my first question,
I am wondering if there is a way to get coordinates based on specific time, for example , I can see veil nebula and I get its coordinates but I should to get these coordinates when it is 02:30 by the night.
I searched but I didn’t find it.
thanks

I can answer myself it is not needed, it is really a stupid question.
Lack of knowledge.
