Municipal fireworks displays in the US are often held on Saturday night, just as it is getting dark -- i.e. right at tzeis hakochavim, time for Ma'ariv, Havdalah, etc.
Assuming there is a vantage point to view the fireworks within walking distance, is there any problem getting into position before Shabbos ends and postponing Ma'ariv, Havdalah, etc, until the fireworks are over?
Does it take something away from the honor of Shabbos to do this? What if it meant missing davening in a minyan?
