you have received a number of great replies... if you were shooting on land... but you are not. now I have have not read all of the replies, but using your short lens... not your long lens will work best for you unless you are over 3/4 of a mile from the launch site. if you are closer to the launch site than 1/4 mile, please find a new site as that is just too close. you will need to shoot at 1/60th sec or faster as the boats movement is going to cause blur... even if the water is like glass. shoot it wide open an pray that you have some good shots... quite frankly, you are doing things backwards to getting great shots... it could happen, but not likely. Sorry for all of the negatives, but you asked how to do this.

I recently purchased a Nikon D7200 and, due to circumstances, the evening of the 4th will be my first night shooting opportunity. I'll be in a boat shooting fireworks in Bar Harbor, Maine. I'd like some pointers on how to achieve superior images, please. My kit includes all Nikon lenses with AF and VR: 18-200mm, 70-300mm, 105mm, 35mm 1:1.8G, 18-55mm, 55-200mm. My first choice would be the 18-200 but will defer to recommendations from those of you who have experience shooting fireworks.
