    I took the following pic with a Canon Powershot Pro1 set on highest
    (superfine and Large) quality, shutter open for 15sec (i know there is a
    term for that but don't know it) on F2.8.

    The picture is very grainy, is there a way to get a good night time
    picture without it being so grainy??

    Any help appreciated as I want to learn to use the camera to it's full
    capacity. Are there any good sites to teach this sort of stuff?

    President Bush was receiving his daily briefing from his defence
    secretary, who concluded: "Three Brazilian soldiers were killed in an
    accident."
    "Oh, no!" exclaimed Bush, who held his head in his hands in a show of
    emotion which startled his staff. Finally the president looked up and
    asked: "Just how many is a brazillion?"

    Are you able to change the ISO setting on that camera (sorry I have a EOS
    10D,so I'm not familiar with yours)? If so, change it to the lowest setting
    (maybe 50?).

    Also, see if you camera can do "dark frame subtraction". Basically once the
    first picture has been taken, an identical picture is then taken immediately
    afterwards except the shutter remains closed. This second shot basically
    only contains the noise from the camera's CCD/CMOS, which is then subtracted
    from the first picture to (hopefully) give a picture which has less noise.

  3. Like he said, use the lowest ISO possible, and turn on Noise reduction,
    or NR or dark-frame subtraction if you have it (RTM).

    Finally, if you are just wanting small prints or web-sized images, you
    can easily blur the image (experiment with the amount and you will
    obliterate most of it without hurting the detail too much), resize it,
    and then sharpen - presto. Or try Neat Image or any of it's
    competitors. At that size, no noise should be visible if you do it
    right.

    Or get a DSLR.

    Noise ninja is good to remove grain (noise). As suggested above, use a
    low ISO... it is likely your camera is set on Auto iso if you don't
    usually control this manualy..... this will not be helping.

    dark fram subtraction was also suggested above..... this involves taking
    2 photos... one normal... and one without exposing the sensor (lens cap
    on)... the noise is then subtracted from the exposed image... your
    camera does not have this function.... but plug "dark frame subtraction
    noise astro" into google... through astrophotography websites you should
    find software that allows you to do this in postproduction... you still
    need to take the second photo though.... unlike camera like the 20d that
    do it automatically.

    Looks like a typical PS Pro night/low light shot. I have one as well:
    great lens but noisy sensor at anything over 100 ISO.
    DSLRs are now the same price as the PS Pro...
