A good tutorial for night shots with the 5700 is here: http://www3.photosig.com/viewarticle.php?id=671
But to answer your question yes, the larger the F value the more star like light will appear, a good compromise is to use a mid value like f4-f5 and a longer exposure. You can buy a corded remote (the MC-EU1) or use the timer so you don't have to hold the button down.

Nicely said nita ,
Would like to add that you can create your own cabel release adapter by ways of traditonal screw cabel onto a metal bracket thats held there by the tripod socket(bend some alloy into proper shape to hold above shutter then drill a correct size hole and attach a washer to keep it through.
I had to write this since I forgot where the article is thats described it. try a search if you dont get what Im saying.
Also its a good idea to bracket since you are shooting digital.

Thank you Nita, I've read the article you've indicated and found it very useful. Do you know if the remote allows for long exposure without needing to keep the finger on the release button ?

When you have the camera set to bulb exposure mode (in "M" Manual), I believe you do have to manually hold down the shutter button on the cable release to continue the exposure. Otherwise you can only go up to 8 sec (? I think that's the limit, it's been awhile since I had a coolpix) by using the timer setting .

Having just read this thread, I am a bit confused by the terms small aperture as used by Christian and Nita's response about large F number. Excuse me if I am wrong Nita, but my experiece has been that the star effect is a result of a small f stop, anywhere from f:11 to f:32 and that this effect would be quite reduced by a larger f stop of say f:4 or 5.6
The attached photo, also posted on this site at http://www.usefilm.com/showphoto.php?id=3241 is an illustration of this techniqe. I have not tried the star effect with my digital camera but I believe it worked with the standard lens due to the internal leaf diaphram. I'm not sure if digital lenses are controlled in the same manner.
Sounds like an experiment waiting to happen.

John, I figured that "large" f values refer to the value of the number rather than to the actual aperture. F16, or f22, would be a "large" f value, but a small aperture, and a f2.8 would be a "small" value, but a large aperture.

John Charlton is correct in his explanation of apentures. Sorry for my incorrect phrasing, but Christian is correct in assuming I was referring to the actual value of the number itself.
